WarnInG - never use waste or reclaimed oil. this results in
damage to the oil pump, saw chain and guide bar.
WarnInG - always loosen locking knob before turning ten-
sion wheel otherwise sprocket cover and tension wheel will be
damaged. Do not over-tighten locking knob.
CHAIN LUBRICATING OIL
Use high quality chain lubricating oil to minimize wear between the saw chain and guide bar while in use.
We recommend using SAE No. 30 in the summer and SAE No. 10 in the winter or when cutting resinous
wood. Check the oil level prior to each use.
Oil tank capacity: 90 cc (3.1 fluid ounces)

CHAIN BREAK OPERATION
1. Loosen the locking knob.
2. Using gloved hand, hold the guide bar nose up and turn the tension wheel clockwise. The chain is correctly
tensioned when it is still possible to raise it by 2-3 mm in the middle of the guide bar.
3. Tighten the sprocket cover by turning the locking knob clockwise.
WarnInG - never touch the chain while chainsaw is running.
Unplug chainsaw from power source before adjusting the saw
chain tension. not doing so may cause severe personal injury
or death.
To test if chain lubricating oil is adequately dispensed onto the guide bar, hold the guide bar above a dry
surface and run the chainsaw for 30 seconds. A thin line of “thrown” oil should be seen on the dry surface.
Never operate the saw without chain lubrication. Even running the saw without lubrication can cause irrepa-
rable harm to the entire cutting attachment.
The chain brake stops the rotation of the chain during kickback. The chain brake does not prevent kickback.
An efficient chain brake stops the chain in 1/10th of a second or less by pushing the front handle guard for-
ward. The chain brake is designed to only stop the chain, if activated, during certain kickback situations. The
system must be properly maintained and in good working order for the chain brake to stop the rotation of the
chain.
To release the chain brake, pull the hand guard back towards the operator until a noticeable click is heard.
