MAINTENANCE

Air filter

The air filter must be regularly cleaned to remove dust and dirt in order to avoid:

SCarburetor malfunctions S Starting problems

S Loss of engine power

S Unnecessary wear to engine parts S Excessive fuel consumption

Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air filter

Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry before refitting it.

An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new

one at regular intervals. A damaged air filter must always be replaced.

Bevel gear

The bevel gear is filled with the right quan- tity of grease at the factory. However, be- fore using the machine you should check that the bevel gear is filled three--quarters full with grease. Use JONSRED special grease.

The grease in the bevel gear does not nor- mally need to be changed except if repairs are carried out.

Sharpening grass cutters and grass blades

WARNING: Always stop the en- gine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cut- ting attachment has stopped com- pletely and disconnect the HT lead from the spark plug before you start to work on it.

SSee the cutting attachment packaging for

correct sharpening instructions.

SSharpen blades and cutters using a single--cut flat file.

SSharpen all edges equally to maintain the balance of the blade.

WARNING: Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be re- used. Only use original blades of the specified type.
