STIHL 180 does not start well when hot

Broken fuel line

During the operation of the chainsaw, vibration occurs, which can cause damage or breakage of the fuel line of the chainsaw. In this case, the chainsaw will stall and it will be impossible to start. To diagnose a malfunction, you need to conduct an inspection and determine the presence of fuel leaks.

STIHL 180 does not start well for hot reasons.

Chainsaw breakdowns often occur due to insufficient chain lubrication due to oil line leakage and clogged channels. Therefore, if the chain becomes dry, it is necessary to urgently clean the channels supplying oil to the tire. Then an inspection of the joints of the pipes with the oil pump fittings is carried out. If a strong leakage of oil from the points of contact or cracks in the oil line is detected, the pipes are changed, and the joints are sealed with a high-quality sealant.

Some parts of chainsaws must be changed after the expiration of the passport service life. Therefore, do not forget to look at the instructions, where they are clearly spelled out. Such parts include the tire, the drive sprocket, the chain, parts of the anti-vibration system.

If the replacement is not done on time, the wear of these components will negatively affect the serviceable parts of the chainsaw. For example, a long delay in replacing a drive sprocket results in increased vibration, which quickly breaks down the crankshaft bearings.

Therefore, it is necessary to regularly check the working depth of the teeth, which should not exceed 0.5 mm. The tire resource is usually enough for 3-4 chains, after which it also needs to be replaced.

If, when inspecting the spark plug, it is found that it is wet and sparking on the contacts does not occur, this means that the problem should be looked for in the ignition system, inspect the coil, check the gap between the flywheel and the coil contacts. You can also check how tightly the cap of the high-voltage wire sits on the candle, and the candle itself. Try to replace it with a new one.

Other malfunctions

  • For many owners, the question regarding the correct idle speed after emptying the fuel from the gasoline tanks is relevant for many owners. According to experts, there is no need to worry too much about this. However, if you have to deal with a similar problem often, then it is enough to manipulate the carburetor by reducing the engine speed in order to restore the normal operation of the tool.
  • In some cases, the owner may need to clean the muffler as this part may be causing the malfunction. This operation is quite simple. It must be remembered that many owners are faced with problematic chainsaw operation due to a faulty carburetor.
  • Although in some cases it may be quite simple to troubleshoot a malfunction, it is most preferable if specialists will repair this equipment. After all, not each of us has the necessary knowledge and skills, and this is fraught with the fact that during self-troubleshooting there is a risk of completely disabling the tool.

Spark plug

The spark plug is one of the main elements of the ignition system. A spark is formed on its electrodes, and if this element fails, it will be difficult to start, or it is not possible at all.

The plug can fail completely, or work intermittently or give out a weak spark. It is quite simple to check the spark plug, for this you need to unscrew it from the engine, attach it to the high-voltage wire cap and, putting it on the cylinder, pull the starter. If the candle is in order, the spark will be powerful with a bluish tinge. A faint reddish spark is a sign of a problem. Defective spark plug must be replaced.
