Chain Brake Operation and Service
Chain Can Move
Chain Brake Operation
This saw is equipped with a chain
brake designed to stop the saw chain
from rotating whenever the brake
lever is moved to the forward (2)
position.
Engaging the brake lever causes a
brake band to tighten around the
clutch drum, stopping the saw
chain.
The chain brake is designed to
engage whenever the brake lever
strikes the operator's hand.
The chain brake can also be
activated by pushing the brake
lever forward manually.
To release (disengage) the chain
brake, pull the brake lever toward you
(position 1).
WARNING!
The chain brake is installed only to
reduce the risk from kickback! The
chain brake is not a substitute for
careful operation!
IMPORTANT!
Release the throttle whenever the
chain brake is activated!

Chain Brake Inspection
(engine "off")
Before inspecting the chain brake,
stop the saw and remove the clutch
cover and clean any dirt or debris
from the chain brake mechanism.
Reassemble the clutch cover to the
saw, and use the following procedure
to test for proper adjustment:
1. Turn the engine "off," and verify
that the ignition switch is in the "0"
or "off" position.
2. Engage the chain brake by manu-
ally pushing the brake lever
forward to position 2 (brake is
engaged).
3. While wearing heavy gloves,
attempt to rotate the saw chain:
Grasp the chain behind one of the
cutters.
Attempt to push the chain around
the bar.
4. If the chain cannot be rotated, no
further adjustment is required. If
any chain movement is possible, go
to "Adjustment" (next page).
