Instructions / Assembly

Caution: Proper saw chain tension is extremely important. If saw chain is too tight, the guide bar and saw

chain will be quickly damaged. If the saw chain is too loose, it may get out of the guide bar groove and

cause an injury.

Note: A new chain will stretch so adjust the tension after a few cuts. Watch saw chain tension carefully

for the first half hour of cutting.

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. 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 flat file. 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 physical effort, and cause high vibrations and a higher rate of wear.
