with both hands with the thumb and fingers encircling
both handles.
This tool is equipped with a variable speed trigger switch. To turn
the unit on, ensure chain brake is not engaged. Push down on
the lock off lever

, shown in Figure N, and squeeze the trigger
switch

. Once the unit is running, you may release the lock off
lever. The farther you depress the trigger, the faster it will operate.
In order to keep the unit running you must continue to squeeze
the trigger. To turn the unit off, release the trigger.
nOTE: If too much force is applied while making a cut the saw
will turn off. To restart saw, you must release the lock off lever
and the trigger switch

your cut again this time with less force. Allow the saw to cut at its
own pace.
WARNING: Never attempt to lock a switch in the
ON position.
Setting The Chain Brake
Your chain saw is equipped with a motor chain braking system
which will stop the chain quickly in case of kickback.
•
Remove the battery from the tool.
•
To engage the chain brake, push the chain brake / front
hand guard

forward until it clicks into place.
•
Pull the chain brake / front hand guard
handle
into the "set" position as shown in Figure O.

•
The tool is now ready to use.
nOTE: In the event of kickback, your left hand will come in
contact with the front guard, pushing it forward, toward the
workpiece. This will stop the tool.
Testing The Chain Brake
Test the chain brake before every use to make sure it
operates correctly.
•
Place the tool on a flat, firm surface. Make sure the saw chain
is clear of the ground.

•
Grip the tool firmly with both hands and turn the chain
saw on.
•
Rotate your left hand forward around the front handle
so the back of your hand comes in contact with the Chain
brake / front hand guard
workpiece. The saw chain should stop immediately.
nOTE: If saw does not stop immediately, stop use of tool and
bring it to a D
WALT service center nearest you.

Common Cutting Techniques
(Fig. A, P, Q, U, V, W)
Felling
The process of cutting down a tree. Be sure battery is fully
charged before felling a tree so you can finish on a single
charge. Do not fell trees in high wind conditions.
WARNING: Felling can result in injury. It should only be
performed by a trained person.
•
A retreat path should be planned and cleared as necessary
before cuts are started. The retreat path should extend
back and diagonally to the rear of the expected line of fall.
(Figure U)
Fig. U
•
Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direction
to judge which way the tree will fall. Have wedges (wood,
plastic or aluminum) and a heavy mallet handy. Remove
dirt, stones, loose bark, nails, staples, and wire from the tree
where the felling cuts are to be made.
•
Notching Undercut - Make the notch 1/3 of the diameter of
the tree, perpendicular to the direction of the fall. Make the
lower horizontal notching cut first. This will help to avoid
pinching of either the saw chain or the guide bar when the
second notch cut is being made (Figure V).
•
Felling Back Cut - Make the felling back cut at least 51 mm
higher than the horizontal notching cut. Keep the felling
back cut parallel to the horizontal notching cut. Make the
felling back cut so enough wood is left to act as a hinge. The
hinge wood keeps the tree from twisting and falling in the
wrong direction. Do not cut through the hinge (Figure V).
•
As the felling cut gets close to the hinge the tree should
13
begin to fall. If there is any chance that the tree may not fall
in the desired direction or it may rock back and bind the
saw chain, stop cutting before the felling cut is complete
and use wedges to open the cut and drop the tree along
the desired line of fall. When the tree begins to fall remove
the chain saw from the cut, stop the motor, put the chain
saw down, then use the retreat path planned. Be alert for
overhead limbs falling and watch your footing.
