Maintenance (continued)

GUIDE BAR

The guide bar has a sprocket at its base that must be lubricated with grease using a lubrication syringe (Fig. 40).

Reverse the guide bar every 8 working hours to ensure uniform wear.

Keep the bar groove and lubrication hole clean using the bar groove cleaner (Fig. 41).

Check the bar rails frequently for wear. If they are sufficiently worn, remove the burs and square-up the rails using the flat file (Fig. 42).

Never mount a new chain on a worn sprocket (Fig. 43). Wear eye protection during maintenance.

AIR FILTER

Rotate the knob (A, Fig. 44) and check the air filter (B) each time you use the chain saw. Wash the filter in a clean, non-flammable detergent liquid (e.g. hot soap water), then dry.

When refitting the air filter (B), fit it into the cover

(A) before reassembly.
