GUIDE BAR AND OIL HOLES

Clean guide bar before use. Follow instructions for removing and installing guide

bar and saw chain. Remove guide bar and clean groove of the guide bar with a

small screwdriver. Clean oil holes with a wire (see below). Check the sprocket

and the clutch and clean the bar mount area before installing the bar. Guide bar

with sprocket nose should be lubricated with grease using a lubricating syringe.

Invert the symmetrically shaped guide bar every 8 working hours or each time

the chain is removed to ensure uniform wear. Check the bar rails frequently for

wear and remove burs and square up the rails using a at le. Clean the Oiler

port on the saw every time the saw chain and guide bar are removed.

SPROCKET

A damaged drive sprocket will cause premature wear or damage of the chainsaw.

Check the sprocket when installing a new chain. When outer diameter of sprocket is worn 0.5mm (0.020”) or

more, replace it. Always clean sprocket, clutch and bar mount area before installing guide bar.

SAW CHAIN SHARPENING

It is advisable to have professional shops sharpen saw chains. It is beyond the expertise of the typical home

owner to sharpen saw chains. An improperly sharpened saw chain will not cut effectively, require more physi-

cal effort, and cause high vibrations and a higher rate of wear.

CARBON BRUSHES

1. Check the condition of the carbon brushes after 50 hours of use of your new chainsaw. If the brushes are

worn to 1/8 inch in length, replace them.

2. Remove the motor cove to inspect the brushes.

3. Replace them if necessary.

REPLACING THE GUIDE BAR

1. To replace the guide bar, remove the adjust block by loosening the screw holding the adjust block to

guide bar.

2. Use the replacement bar recommended by manufacturer. Attach the adjust block to new guide bar by

tightening the screw.

3. Refer to "Installing Guide Bar and Chainsaw" section in manual (p. 8)

MAINTENANCE



Before accessing the carbon brushes, be sure that the

chainsaw is disconnected from the power source.
