CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING.
CHECK GUIDE BAR
Conditions which require guide bar mainte- nance:
SSaw cuts to one side or at an angle. S Saw has to be forced through the cut. S Inadequate supply of oil to bar/chain.
Check the condition of guide bar each time chain is sharpened. A worn guide bar will damage the chain and make cutting difficult. After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole.
To maintain guide bar:
S Move ON/STOP switch to STOP.
S Loosen and remove bar nuts and clutch cover. Remove bar and chain from saw.
S Clean the oil holes and bar groove after each 5 hours of operation.
Remove Sawdust From
Guide Bar Groove
