A guide to the main Power Barrows maintenance operations

Power barrows are a key aid for transporting heavy, bulky materials on difficult surfaces, such as rough and sloping terrain. They can be used for a variety of applications in both the hobby and professional fields and, thanks to their robustness and strength, allow loads of up to 1000 kg to be transported on uneven and sloping terrain. Proper maintenance of power barrows is therefore essential for their correct and ready use.

But what maintenance work does a power barrow require?

In this guide we will give a complete overview of all necessary maintenance work, all aspects to be evaluated and the most correct procedures to follow.

The two stages of petrol power barrow maintenance

Power barrows are widely used in various fields, from construction to gardening, from DIY to professional, in all seasons. In spring, for example, they can be used to transport plant pruning waste, in autumn they are perfect for transporting firewood to be used in winter.

Since they can be used throughout the year, it is essential to carry out maintenance on power barrows, which we can sum up in two main steps:

1. Routine maintenance;
2. Non-routine maintenance in case of an extended period of standstill.

1. Routine maintenance of the power barrow

We will first look in detail at the routine maintenance of the power barrow. Regular and careful care preserves engine efficiency, vehicle safety and component durability.

Below, we have listed all the various steps to follow and detailed instructions for each operation – from checking the oil to lubricating the moving parts – that are essential to ensure high performance and reliability for your power barrow.

1. Checking the engine oil level;
2. Cleaning and replacing the air filter;
3. Checking the spark plug and replacing it (if necessary);
4. Checking the body of the power barrow (especially the one with hydraulic tipping);
5. Condition and tension of the engine transmission/gearbox belt;
6. Power barrow ordinary maintenance.

1.1 Power barrow maintenance: checking and topping up the engine oil

Checking the engine oil level is essential in the maintenance of power barrows to ensure proper lubricationand prevent overheating of internal components. A low oil level can cause serious damage to the engine, hence top up the oil if the level is low.

1. Place the power barrow on a flat surface and switch off the engine, allowing it to cool down for at least 5–10 minutes.
2. Find the oil dipstick, usually located near the tank.
3. Pull the dipstick out, wipe it clean with a cloth to remove residue, then slide it back in all the way without tightening it.
4. Pull the dipstick out and check that the oil level is between the minimum and maximum marks.
5. If the level is low, top up the engine oil with the recommended type, pouring in a little at a time and checking the level with each top-up to avoid overfilling. Refer to the owner’s manual to find out the type of engine oil for your power barrow.
6. After reaching the correct level, tighten and secure the dipstick.

Tip: The oil level should be checked every 10 hours of use, or at least once a month if the power barrow is used less frequently.

1.2 Air filter check

The air filter prevents dust and debris from entering the power barrow engine, ensuring clean and efficient combustion.

1. Turn the power off and remove the filter cover, which is usually located on the side of the engine.
2. If you are not sure of the type of filter fitted to your power barrow, take the filter out and check what type it is (foam or paper). Alternatively, you can refer to the instruction manual.
3. For foam filters: wash it with soap and water, let it dry completely and lightly moisten it with filter oil.
4. For paper filters: blow gently with compressed air to remove dust. If it is very dirty, replace it with a new one.
5. Reinstall a clean or new filter, close and secure the cover.

Tip: For proper maintenance, clean the filter every 25 hours of use or at least once a month. The filter must be replaced if it is excessively dirty or damaged.

1.3 Power barrow maintenance: checking the spark plug and replacing it (if necessary)

The spark plug is responsible for the ignition of the fuel in the engine. A dirty or worn spark plug can affect engine performance and increase fuel consumption.

1. Make sure that the engine is switched off and cold.
2. Disconnect the spark plug cap to prevent accidental starting.
3. Use a dedicated spanner to remove the spark plug, then inspect the electrodes.
4. If the spark plug appears black or has deposits, clean it with a wire brush. In case of wear or visible damage, replace it with a new spark plug of the same type.
5. Screw the new (or clean) spark plug into the engine and reconnect the cap.

Tip: Check the condition of the spark plug every 50 hours of use, or at least every two months.

1.4 Checking the body (in power barrows with hydraulic or manual tipping)

The tipping mechanism of the body must work properly to ensure safe and smooth operation. Efficient tipping of the body allows the material to be easily unloaded, while any malfunction can compromise the stability of the load and vehicle operation. It is recommended to check its condition every 20 hours of use, especially when used on uneven surfaces or under heavy loads.

• Hydraulic body: Check the hydraulic oil level and verify that there are no leaks along hoses and connections. Small leaks may signal worn seals or loose connections, requiring immediate action to prevent pressure drops.
• Manual tipping body: Check the hinges and pivots to ensure that they are secure and wear-free. Any clearance or looseness can compromise tipping stability, rendering it dangerous.
• Motion test: Operate the body to ensure that the motion is smooth and free of jams or friction. In case of stiffness, consider lubricating or cleaning the hinges and joints.

1.5 Checking the condition and tension of the engine drive/gearbox belt

The engine drive/gearbox belt plays a key role in delivering power from the engine to the transmission, ensuring that the gears work properly and that the power barrow can move. A well-maintained and well-tensioned belt ensures efficient performance, while a worn or loose belt can cause slipping, especially in high gears under load. It is recommended to check the condition and tension of the belt regularly.

As far as the condition of the belt is concerned, one in good order must be free of cracks, signs of wear or fraying along the edges. The surface should be smooth and even, with no worn or visibly worn parts. On the other hand, if the belt is cracked, showing signs of dryness, wear or frayed edges, it is likely that it is not properly delivering the motor’s power, causing slippage and loss of efficiency. In this case, it is recommended to replace it with a new one to avoid any damage to the drive system.

Before checking the belt tension, it is necessary to know that a belt which is too loose can cause slippage, especially in high gears (second and third) when the power barrow is under load. The tension can be checked by pressing the centre of the belt with your finger; if the belt moves too much, it may be too loose.

Since power barrows do not have an automatic tension regulator, the only way to correctly tension the belt is to move the engine slightly towards the operator.

Here’s how to “tension” the belt:

1. Loosen engine bolts: the engine is secured to the frame using screws and bolts on an oval housing, which allows the engine to slide slightly once these fasteners are loosened.
2. Move the engine: with the screws loosened, move the engine back a few millimetres (towards the operator) until reaching the desired belt tension.
3. Re-tighten the bolts: when the correct tension is achieved, re-tighten the bolts and check whether the engine is securely fastened to the frame.
4. Carry out a final test: After tensioning the belt, switch the power barrow on and try using the gears, paying attention to any slippage in high gears and under load. If the problem persists, check the tension again or consider replacing the belt if it is worn.

1.6 Power barrow regular cleaning

Regular cleaning of the power barrow is considered a good practice for proper power barrow maintenance, as it is essential to keep all its components in good condition. Dirt, dust, mud and plant residues can build up on the frame, near the bearings and moving parts, or even in the engine compartment, causing friction and interfering with the motion of mechanical parts. Keeping the power barrow clean also allows early identification of any damage, such as wear or cracks, that could compromise safe operation.

1. Preparation – Make sure the power barrow is placed on a stable surface, with the engine switched off and cooled.
2. Mud and coarse debris removal – Use a hard bristle brush or squeegee to remove thicker residues such as mud and debris accumulated in wheels, tracks and on frame parts.
3. Cleaning the frame and outer parts – Use a damp soft cloth and, if necessary, a mild detergent to remove dust and dirt. Avoid overly aggressive products that could damage painted surfaces or plastic components.
4. Cleaning mechanical parts – For mechanical parts (such as bearings and joints) that might build up oil and grease, use a cloth moistened with a special cleaner for mechanical parts, followed by a lubricant after drying.
5. Cleaning the engine and fan – Use an air compressor or soft bristle brush to remove dust and dirt from the cooling fins and areas around the engine, taking care not to force the air directly into sensitive parts.
6. Rinsing (if necessary) – For stubborn dirt, the power barrow can be rinsed with water, avoiding directing the jet towards electrical parts and the carburettor.

Tip: Clean the power barrow after each use, especially if it has been used on muddy or dusty ground. A thorough cleaning should be performed at least once a month.

Safety notice: When cleaning, always wear protective gloves and, when using cleaning agents, also wear safety goggles to protect your eyes from splashes.

2. Non-routine power barrow maintenance

When the power barrow is idle for a long period, such as during winter or after seasonal use, it is essential to carry out ‘Non-routine’ maintenance before putting the power barrow back in service. This process helps avoid starting problems, reduces the risk of breakdowns during use and keeps the machine in optimal shape over time.

The main tasks in the non-routine power barrow maintenance relate to:

1. Changing the fuel and cleaning the tank;
2. Checking the battery charge;
3. Checking the transmission or gear lever ;
4. Checking the tire pressure level or track tension (if fitted);
5. Lubricating moving parts (joints and bearings)

In the following paragraphs, we will analyse each operation in detail, explaining how to perform it correctly, why it is important and how often to carry it out after long periods of standstill.

2.1 Changing the fuel and cleaning the tank

After a long period of standstill, it is essential to change the fuel in the tank, as it can deteriorate and leave residue that could compromise the fuel system. Changing the fuel is a precautionary measure to avoid ignition problems and clogging inside the engine. Here’s how to do it right:

• Empty the tank completely, collecting the old fuel in a suitable container for disposal according to regulations.
• Clean the inside of the tank using a soft cloth toresidue or any traces of dirt.
• If necessary, use a specific fuel cleaner to ensure thorough cleaning.
• After cleaning is complete, fill the tank with new fuel to ensure optimal combustion and reduce the risk of difficult starting.

2.2 Checking and charging the battery on battery-powered power barrows

In battery-powered power barrows, battery condition and charge have a direct impact on service life and work performance. During downtime, the battery may gradually run down, and it is important to check its condition before each use to avoid interruptions. That is why we always advise unplugging the battery if your power barrow is to be stored for a long period of time. Furthermore, each battery has a limited service life, so it is essential to monitor its performance and replace it when it can no longer hold a sufficient charge.

• Visually check the battery: check for cracks or bulges, signs of wear or oxidation on the terminals, which are indicative of deterioration.
• Charge the battery before each use: use a compatible charger and plug it in until full charge is reached. Some battery charger models provide indications of residual capacity, a useful tool for assessing battery efficiency.
• Clean the terminals and check the connections: after charging, clean the terminals with a dry cloth to avoid oxidation and ensure a stable connection.
• Replacing the battery: in case of a significant drop in performance (e.g. if the power barrow works for less time than normal or does not recharge completely), it is recommended to replace the battery.

Typically, a battery has a service life of 3–5 years, but this may vary depending on the intensity of use. Replace it with a specific recommended model battery to ensure compatibility and optimal performance.

2.3 Power barrow maintenance: checking the transmission or gear lever

The transmission and gear lever are crucial components for ensuring safe driving and precise manoeuvrability of the power barrow, especially when transporting heavy loads or travelling over uneven surfaces. Smooth transmission operation reduces the risk of sudden jamming or malfunctioning, which could compromise operator safety and machine efficiency. It is recommended to check the transmission and gear lever at least once a season, increasing the frequency if the power barrow is used intensively.

1. Switching off the power barrow – Make sure the machine is switched off and placed on a stable surface, avoiding the risk of accidental motion during inspection.
2. Visually check cables and levers – Inspect connecting cables and transmission levers for wear, cracks or looseness. Worn or loose cables can cause shifting inaccuracy and should be replaced to prevent them from breaking during use.
3. Check lever operation – Shift the gear lever to all positions (e.g. forward, reverse and idle) to ensure that transitions are smooth and free of resistance or friction. Should jamming or resistance occur, the mechanism may need to be adjusted.
4. Lubricate pivot points – If the lever is affected by friction or rigid movement, apply a lubricant specifically for moving parts to the pivot points and connections of the lever. This helps to maintain smooth motion and reduces wear and tear.
5. Tighten loose bolts – Check that the bolts and nuts that secure the transmission are tight; if necessary, use a suitable spanner to tighten them, avoiding unwanted movement during shifting.
6. Final test – After checking and lubricating, start the power barrow briefly and test the gearbox on a flat surface to ensure that the transmission responds smoothly in all positions.

2.4 Checking the tyres and their pressure or track tension (if fitted)

Correct tyre pressure and track tension are essential to maintain the stability and manoeuvrability of the power barrow. Flat tyres or loose tracks can compromise grip on the ground and reduce manoeuvring precision, increasing the risk of accidents and early wear of components. This check should be carried out every month, but is also recommended before intensive use or in difficult terrain.

How to proceed (for tyres):

• Use a pressure gauge – Check the pressure of each rubber with a reliable pressure gauge that allows accurate measurement of pressure levels.
• Compare values – Check that the measured pressure matches that recommended by the manufacturer, which may vary depending on the model of the power barrow and the expected load. The ideal pressure is usually specified in the manual or on the sidewall of the tyre.
• Inflate or deflate tyres – If the pressure is lower or higher than recommended, use a compressor to inflate the tyre to the correct level, or release air to reach the ideal value. Correct tyre pressure ensures optimal grip and limits tyre wear.

How to procced (for tracks):

• Track visual inspection – Carefully inspect the surface of the tracks for cuts, cracks or excessive wear. A worn track can reduce grip and damage the traction mechanism.
• Tension check – Make sure the tension is correct by following the instructions in the manual: too low a tension can cause slipping, while too high a tension can accelerate wear on tracks and mechanical components.
• Tension adjustment – If the tracks are too loose or tight, use the adjustment system on the power barrow to achieve the correct tension level. Generally, the tension can be adjusted by acting on the tensioning bolts located on the sides of the tracks.

In both cases, we recommend carrying out a short test run of the power barrow after adjusting the tyre pressure or track tension to check whether it reacts stably and safely on a flat surface.

2.5 Power barrow maintenance: lubricating moving parts (joints and bearings)

Lubricating the moving parts of the power barrow is essential to avoid friction, reduce early wear and ensure that the joints and bearings move smoothly. Proper lubrication extends the service life of mechanical components and prevents sudden malfunctions, which could slow down work and increase repair costs.

1. Preparing the power barrow: Place it on a stable surface and make sure the engine is switched off and cold for safe operation.
2. Choosing the right lubricant: Use a lubricant specifically intended for mechanical moving parts, such as spray oil or grease, always following the manufacturer’s instructions. This ensures effective and long-lasting lubrication without risking damaging mechanical parts.
3. Apply lubricant to the joints and bearings: Carefully apply a small amount of lubricant to each pivot point and to the bearings. Avoid exceeding the amount in order not to create a build-up, which could gather dust and dirt and, in the long run, impair operation. In the case of bearings, gently rotate the part to spread the lubricant evenly.
4. Cleaning the excess: Remove any excess lubricant with a soft cloth, so that the surfaces remain clean and free of residue.
5. Final check: After lubrication, move the moving parts by hand to make sure that the joint or bearing slides without resistance. A smooth motion confirms that lubrication has been carried out correctly.
