Figure 4
Rotate the socket head screw on the
front of the saw head clockwise to take
up the slack in the chain. (see gure 2
from previous step)
Replace the sprocket cover, bar clamp
and socket head screws in that order.
Adjust the tension on the chain before
use.
ADJUSTING SAW CHAIN TENSION
With the battery removed from the
power handle, pull the center of the
chain away from the bar at the center
of the bar with your ngers (always
wear gloves). The tension is correct
when you can pull the chain 1/8”
from the bar and it snaps back when
released. (see gure 5) The chain
should not sag away from the bar.
Figure 5
To adjust the chain tension, loosen the
socket head screw that hold the bar
clamp.
Turn the socket head screw on the
front of the saw head to loosen or
tighten the chain as needed. When the
chain is the correct tension, tighten the
two socket head screws that hold the
bar clamp in place.
Do not over-tighten the chain as this
will lead to premature wear of the
chain and bar. Over-tightening can
also reduce battery life and cause the
circuit breaker to trip.
Check the tension on the chain often
when it is new. New chain stretches in
the initial few hours of use.
OILING THE CHAIN
Oil the chain before each use with
unused SAE30 weight motor oil or saw
chain oil. Lubricate the chain along its
entire length.
