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 cover to inspect the brushes.
3. Replace them if necessary.
MAINTENANCE
Before accessing the carbon brushes, be sure that the
chainsaw is disconnected from the power source.
