Chain Tension Adjustment
1. Loosen the guide bar nuts.
2. Using a gloved hand, hold the guide bar nose up and turn the chain tension
adjuster screw clockwise until saw chain touches bottom of guide bar.
Tighten both guide bar nuts with the guide bar nose held up.
3. Test the chain tension by pulling the saw chain around the guide bar with a
gloved hand. Reduce saw chain tension if tight spots are felt.
4. Keep the proper tension on the saw chain at all times.
Chain lubrication
/
verification
To test if chain lubricating oil is adequately dispensed unto the guide bar, hold
the guide bar above a dry surface and engage the throttle to half speed for 30
seconds. A thin line of “thrown” oil should be seen on the dry surface. Never
operate the saw without chain lubrication. Running the saw without lubrication
even for a short moment, can cause irreparable harm to the entire cutting
system.
Kickback safety precautions
Kickback is the name given to a sudden, rapid upward movement of the saw
cutting mechanism in an upward arc towards the operator. Kickback occurs when
the upper quadrant of the bar nose comes in contact with a solid object or is
pinched. The rotational force of the chainsaw can be reversed in the opposite
direction of the chain movement. This may fling the bar up and back in an arc
towards the operator. Serious injury or even death can result from contact
between the moving saw chain and the operator.
The best protection against injury due to kickback is to avoid
situations
that can cause kickback:
- Grip saw firmly. Hold the chain saw firmly with both hands when the motor is
running. Use a firm grip with thumbs and fingers encircling the chain saw
handles.
- Do not over-reach. Keep proper footing and balance at all times.
- Don’t let the nose of the guide bar contact a log, branch, ground or other
- obstruction.
- Don’t cut above shoulder height.
-
Use devices such as low kickback chain, guide bar nose guards, chain brakes
and special guide bars that reduce the risks associated with kickback.
- Only use replacement bars and chains specified by the manufacturer or the
equivalent.
CHAIN BRAKE
OPERA
TION
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 closing a “brake band” around the clutch drum. 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.
!
WARNING!
Never touch the chain while motor is running. Turn off motor before adjusting
the saw chain tension. Not doing so may cause severe personal injury or death.
