10 MAINTENANCE INSTRUCTIONS
All chain saw service, other than items listed here in your user manual maintenance instructions,
should be performed by a professional.
10.1 Preventive maintenance
A good preventive maintenance program of regular inspection and care will increase life and
improve performance of your chain saw. This maintenance checklist is a guide for such a
program. Cleaning, adjustment, and parts replacement may be required, under certain
conditions, at more frequent intervals than those indicated.
10.2 Winter maintenance
Your chain saw requires winter maintenance. Please contact your local dealer for this.
It includes the following:
− Replacing spark plug
− Sharpening the chain
− Cleaning of air filter (Replacement if necessary)
− Cleaning of guide bar
− Oil pump check up
− Thorough cleanup
− Fine tuning and testing
10.3 Air filter
Caution: never operate saw without the air filter. Dust and dirt will be drawn
into engine and damage it. Keep the air filter clean!
To clean air filter:
▪ Release the lever (A) holding the air filter cover in place. Remove the top cover (B) by
releasing the cover retaining lever. Cover will lift off. (Fig. 16a)
▪ Lift the air filter out of air-box (Fig. 16b).
▪ Clean air filter with compressed air. When heavily polluted, wash filter in clean, warm,
soapy water. Rinse in clear, cool water. Air dry completely.
Note: it is advisable to have a supply of spare filters.
▪ Install air filter. Install engine / air filter cover. Make sure the cover fits properly. Close the
cover retaining lever.
Warning: never perform maintenance when the engine is hot, to avoid any
chance of burning hands or fingers.
