WARNING
: Wear protective gloves
when handling chain. The chain is sharp and
can cut you even when it is not moving.
It is normal for a new chain to stretch during the

check your chain tension frequently and adjust
the chain tension as required. Always check
chain tension each time you use and refuel
your saw or when any sag in the chain is noted.
1. Move ON/STOP switch to the STOP
position.
2. Make sure chain brake is disengaged
(see CHAIN BRAKE in the OPERATION
section).
IMPORTANT:
Before proceeding to next

upright position as shown in illustration.
Chain will not tighten properly if the unit is not
in an upright position.
3. Use the chain adjustment tool (bar tool)
to move chain around guide bar to en-
sure kinks do not exist. The chain should
rotate freely.

BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
Only use Bar and Chain Oil for bar and chain
lubrication.
