Cleaning the air filter Dismantle the air filter cover and remove the air filter. Wash in clean, warm soapy water. Ensure that the
filter is dry before refitting. An air filter used for a long period of time can never be cleaned completely. Therefore it is necessary to replace the filter from time to time with a new filter. A damaged air filter must always be replaced.
Angle gear
The angle gear is filled with a sufficient quantity of grease at the factory. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Use JONSERED special grease.
Normally, the grease does not need to be changed except when the angle gear is repaired.
If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.
Filing the grass blade
!WARNING!
Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it.
•See the cutting
equipment’s packaging for correct filing instructions.
• The blades are sharpened using a single cut flat file.
• Sharpen all edges equally to maintain the balance of the blade.
!WARNING!
Always discard a blade that is bent, twisted, cracked, shattered or damaged in any other way. Never attempt to straighten a twisted blade for use again. Only use original blades of the prescribed type.
