Having a Bosch rotak lawn mower that won’t start or experiencing other problems?
This article will show you what to check before you pay someone to repair your mower.
It may be something as simple as the spark plug, fuel valve, or over-filling.
But before you pay someone to repair your lawn mower, check to make sure the batteries are at least 12.5 volts.
The battery is also important because it powers the electric motor and cuts grass.

Common causes of a lawnmower that won’t start
There are several reasons why your Bosch rotak lawn mower isn’t starting. If you see a white film on the gas gauge, you might need to change the oil.
The oil can be dirty from rain and can cause the engine to have difficulty starting. Another problem could be a faulty spark plug.
They could be dirty, disconnected, or simply worn out. Check these items for loose or broken connections. You can find them on the back or side of the engine.
First, you should check the spark plug. The spark plug is a small plug that controls the engine’s speed and should be held tightly against the engine. If you don’t have an assistant, try using a plastic clothes peg.
Make sure that the spark plug is properly attached and screwed in. Also, you should make sure that the “dead man’s handle” control is tight against the handle when starting the mower.
If it doesn’t start, you may need to turn on the manual choke. Be sure to do this only if the engine has been running for more than five minutes.
The oil level should be checked regularly. Check the oil level in the tank after using the mower several times a month or so.
You should also change the oil as necessary and add a few drops of oil. If this doesn’t work, you can remove the oil pan and clean it manually. Another simple way to prevent fuel from getting to the carburetor is to put some oil in the spark plug hole.
Proper fuel valve
Replacing the fuel valve on your Bosch rotak lawn mower is easy. This part sits between the carburetor and gas tank and is governed by the ignition key.
When the key is turned off, the valve retracts and prevents fuel from entering the engine.
To prevent this from happening, you should shut off the valve whenever you’re not using your mower. A fuel stabilizer can also be purchased for your mower to ensure its optimal operation in winter.
The fuel shutoff solenoid is an electrical valve installed on most modern Walk-behinds, Tractors, Ride-ons, Zero-turns, and zero-turn lawn mowers. This component connects to the fuel bowl via an electrical connector.
To replace the fuel valve on your mower, follow the steps below:
A properly functioning spark plug works in conjunction with the ignition coil to produce a timed spark within the cylinder. The spark plug itself is a simple device. It has a base electrode that passes through a ceramic insulator.
Another electrode is fixed on the base in a specific gap. This gap is where the spark is produced. If the valve is closed or dirty, the mower will not start.
Bad spark plug
If your lawn mower is having trouble starting, it might be time to replace the spark plug. The spark plug ignites the air and fuel mixture within the combustion chamber, which drives the piston that spins the mower’s blades.
Although spark plugs are designed to last for several years, they do have a limited life span. A failed spark plug can make the mower difficult to start or cause the engine to run more slowly than it should.
A faulty start switch can also cause your mower to not start. Test the switch with an ohm meter, and if it doesn’t spark, replace the switch.
Make sure that the switch is connected to a functioning power source. Once the spark plug has been replaced, try to start the lawn mower again. In the meantime, you should check the start switch with an ohmmeter to ensure that it is working properly.
If the spark plug on your lawn mower is faulty, it can affect the engine’s performance.
The spark plug is the most basic component of a lawn mower’s engine, so a basic understanding of how it works can help you diagnose and fix the problem.
It can be repaired if the electrode has become wet or distorted, but if it has been damaged physically, it must be replaced.
Overfilling
If you find that your Bosch rotak lawn mower overfills oil, the problem may lie in the fuel level. Check the level of the oil by removing the dipstick cap and wiping it clean before reinserting it. Compare the level with the recommended fill line.
If it is too high, drain the oil and refill it to the proper level. Add a small amount at a time until it matches the recommended line.
To test for overfilling oil, remove the oil tube from the engine. After that, tilt the mower so that the carburetor faces up. This prevents oil from entering the combustion chamber and carburetor. When the mower is tilted, clean up any spilled oil.
Make sure to clean all parts of the mower before you start the engine again. In some cases, oil will spill out from the crankcase, so be careful not to overfill it.
In some cases, overfilling can cause the engine to shut down or produce black smoke. This can occur because of a clogged air filter, oil overflow, or worn piston rings. If you notice black smoke coming from the exhaust, clean the air filter and check the oil level.
If the engine does not start, contact a qualified repair technician. Another sign of overfilling is grass not being cut correctly. The blade may be twisted or blunt. The cut might be uneven.
Viruses
If you are having trouble starting your Bosch Rotak lawn mower, then there may be a virus on your machine. There are a few ways to check for virus infections on your lawn mower.
The most common way is to perform a software update. Other methods may involve contacting a local dealer to receive a free virus scanner.
Viruses are typically caused by software that is outdated or not updated properly. If you suspect that a Bosch lawnmower has a virus, then you need to contact the manufacturer for advice.
The cutting performance of a lawn mower is a key factor when assessing its quality. The Bosch Rotak series is renowned for its high-quality mowing performance, but if you want a simple mower, you should opt for a low-end model.
The Bosch Rotak 34 has excellent performance on longer grass. The mower also performs well in damp conditions, though Bosch warns against using it on wet grass.
The smallest and cheapest Bosch lawnmower, the Rotak 32, is not designed to handle larger gardens. If you are using it in a large garden, you will likely run into problems with cutting and trimming.
The reason for this is that the Rotak 32 is designed for small to medium-sized gardens. The Bosch Rotak 32 is compact and lightweight, and has a 31-liter collection box.
Although the Rotak 32 is not a powerful mower, it will keep your garden trimmed.
Overheating
If your Bosch rotak lawn mower is overheating, you may have a few possible causes. The first thing you need to do is check your oil level.
You should add oil as needed to prevent engine seizing. However, you should check the oil level throughout the entire season. If you forget to add oil, your mower will seize up. So, what should you do? Here are some tips to keep your lawn mower cool and running smoothly.
Another cause of Bosch rotak lawn mower overheating is a bent or loose blade. While a bent or loose blade might seem like a minor thing, it will cause your lawn mower to overheat.
A bent or loose blade will make your lawn mower work less efficiently and put undue strain on the motor/engine.
If you notice a bent or loose blade, it is likely that the blade is the problem. If you notice a bent blade, it’s time to replace it.
When you’re changing a coil, be sure to get a new one that has the same part number. It’s important to find the exact part number to avoid making a mistake.
The coil is one of the cheapest parts on a lawn mower, so you need to make sure it’s working properly. Changing a coil is relatively easy – you can order the right coil online or from the manufacturer. Then, just install the new one and try your lawn mower again.
Damaged components
If you notice that your Bosch rotak lawn mower has stopped working properly, there are a few possible causes. In general, the motor is to blame, but there are some other issues that can cause it to stop working altogether.
One of the most common causes of lawn mower cutouts is improperly sharpened blades, and this is something that you should immediately address. If your Bosch mower is cutting out often and is causing excessive vibration, then it is highly likely that one of these issues is the cause.
You must make sure that your handle is properly attached to the body of the mower. If the handle does not have a tight connection, use a pipe clamp to fix the problem. Be sure to place the clamps on either side of the broken handle.

Also, make sure that the pipe clamps are close enough to the break to wrap around the aluminum rod.
Once you have secured the handle, you can then proceed with fixing any loose connections.
Another important thing to do is to check if the lawn mower has obvious faults or damaged components.
Also, make sure that the deflector guard is properly fitted. If not, you can always contact the Multiservice Center for assistance.
The center will offer you a variety of mutually beneficial benefits and will fix the faults quickly and effectively. If the problem persists, contact an authorised customer service agent for Bosch garden products.
