1. Check the chain tension by pulling the saw
chain away from the chain bar. A properly
tensioned chain should have roughly 1/8
inch (3 mm) of distance between itself and
the bar guide (Fig. 1).
2. If adjustments are needed, loosen the bar
adjustment locking knob one full turn.
3. To adjust the saw chain tension, rotate the
chain tensioning wheel (Fig. 2). Rotating
the wheel upwards increases the tension
while rotating it downwards decreases
tension. A properly tensioned chain should
have no sag (Fig. 3) and should only be

WARNING!
If any part of the Chain Saw is missing or
damaged, do not connect the Chain Saw
to the power source until the damaged
part is repaired or replaced.
Unplug chain saw from power source
before adjusting saw chain tension.
Cutting edges on chain are sharp. Use
protective gloves when handling chain.
ALWAYS Maintain proper chain tension.
A loose chain will increase the risk of
kickback. A loose chain may jump out of
chainbar groove. This may injure operator
and damage chain. A loose chain will
cause chain, chain bar, and sprocket to
wear rapidly. The chain life of the saw
chain mainly depends upon sufcient
lubrication and correct tensioning. Avoid
tensioning the chain if it is hot, as this
will cause the chain to become over
tensioned when it cools down.

able to be pulled 1/8 inch (3 mm) away
from the chain bar of the saw.
4. Once the chain is properly tensioned,
tighten the bar adjustment locking knob.
DO NOT over-tension the chain: this will
lead to excessive wear and reduces the life
of both the bar and chain.
NOTE: The saw chain must be tensioned
properly in order to ensure safe
operation. The chain tension is optimal
if the saw chain can be lifted 1/8
inch (3 mm) from the center of the
chain bar. Since the saw chain heats
up during operation, its length can
thereforeuctuate.Checkthechain
tension every 10 minutes of operation
and adjust as necessary, particularly
for new saw chains. Slacken the saw
chain after the work is completed
since it shortens when cooling down.
In doing so, you can elongate the
chain’s life and prevent damage.
