Maintenance and Repair

Never operate a chain saw that is damaged, improperly

adjusted or not completely or securely assembled.

Follow the maintenance and repair instructions in the

appropriate section of this manual.

WARNING !

Always stop the engine and make sure that the

chain is stopped before commencing any mainte-

nance or repair work or cleaning the saw. Allow the

chain saw to cool off before doing any maintenance

work (burn hazard)! Chain saws with catalytic con-

verter take longer to cool down! Do not attempt

any maintenance or repair work not described in

this manual. Have such work performed by your

DOLMAR service shop only.

Maintaining and storing the saw

Keep the chain, bar and sprocket clean and lubricated;

replace worn sprockets or chains.

Keep the chain sharp. You can spot a dull chain when

easy-to-cut wood becomes hard to cut and burn marks

appear on the wood.

Keep the chain at proper tension. Tighten all nuts, bolts

and screws except the carburetor adjustment screws

after each use.

Keep spark plug and wire connection tight and clean.

Store saws in a high or locked place, away from

children.

WARNING!

5. Logs under strain require special attention to

prevent the saw from pinching. The rst cut is

made on the compression side to relieve the

stress on the log (see g. 33, 34). The bucking

cut is then made as shown. If the saw pinches,

stop the engine and remove it from the log.

WARNING!

6. Only properly trained professionals should work

in an area where the logs, limbs and roots are

tangled (i. e. a blowdown area, g. 35). Working

in blowdown areas is extremely hazardous.

WARNING!

7. Drag the logs into a clear area before cutting.

Pull out exposed and cleared logs rst.
