Part One
Set-Up
This section will cover assembly of the saw and prepara-
tion for operation. All necessary tools and equipment have
been included with your saw.
THE CHAIN BRAKE
The saw is shipped with the chain brake engaged. This
chain brake is designed to stop the rotation of the chain in
l
ess than one-twentieth of a second. If kickback should
occur, the violent reverse action will drive the chain brake
handle back into the operator's top hand, engaging the
chain brake and stopping movement of the chain. We
utilize a sealed inertia chain brake which works on the
same principle as an auto seat belt.
The chain brake has three positions -
Fig. 3. Back position, to disengage chain brake.
To disengage the chain brake, pull the chain brake handle
back completely to the saw's top handle (Fig. 3). It is
important that the chain brake handle comes to full contact
with the saw's handle. Any obstructions, such as your
hand, will prevent disengagement of the chain brake. Once
you have pulled the chain brake handle back completely,
let go and it will snap back to the center or operating
position.
THE CLUTCH COVER
Now, place the power head on your work surface. Once
you have disengaged the chain brake, use the combo bar
wrench to loosen the two clutch cover nuts (Fig. 4).
Fig. 1. Neutral position, chain brake disengaged.
During operation, the brake is in the neutral, or center
position (Fig. 1). This allows the chain to turn freely.
Fig. 4. Clutch cover nuts.
Fig. 2. Forward position, chain brake engaged.
When engaged, the chain brake handle is in the fully
forward position (Fig. 2). At this point, the chain will not
turn.
Remove the clutch cover. Now you can visually inspect the
chain brake to see how it operates. When engaged, the
chain brake band grabs the spinning clutch drum and
i
mmediately stops it.
