Checking and/or changing the spark plug
The type of snow clearer is equipped with a two-cylinder engine. This means that it has two
sparkplugs. These are screwed into the cylinder head.
The sparkplug is a crucial component which plays a significant role in determining combus
tion efficiency. You must therefore check the sparkplugs after every 50 hours of use.
For your information:
Read the engine manual thoroughly.
• Turn the engine off and leave to cool down. Remove the key
from the ignition.
• Remove both sparkplug caps from the sparkplugs.
• Clean the area around the spark plug and remove the spark
plug from the cylinder head. (SW 13/16”)
• Using a feeler gauge, check whether the distance between
electrodes is 0.8 mm.
• If necessary, bend the side electrode carefully until the correct distance has been reached.
• The sparkplug must be replaced if it shows heavy deposits or is very dirty.
• Sparkplugs must be replaced after 200 working hours.
Caution:
Replacing an old sparkplug or putting in a new one must be done with utmost
caution, avoiding any possible damage to the screw thread in the cylinder.
• Secure the sparkplug with a torque of 20 Nm.
