IF SAW STALLS, RELEASE THE TRIGGER SWITCH AND BACK THE
SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN THE
CUT AND CLEAR OF THE CUTTING EDGE BEFORE RESTARTING.
As you finish a cut, release the trigger switch and allow the blade
to stop before lifting the saw from the work. As you lift the saw, the
spring-tensioned lower blade guard will automatically close under the
blade. Remember the blade is exposed until this occurs. Never reach
under the work for any reason. When you have to retract the lower
blade guard manually (as is necessary for starting pocket cuts), always
use the retracting lever.
WARNING: When cutting thin strips, be careful to ensure that
small cutoff pieces don't hang up on the inside of the lower blade
guard.
RIPPING (FIG. 13)
Ripping is the process of cutting wider boards into narrower strips –
cutting grain lengthwise. Hand guiding is more difficult for this type of
sawing and the use of a D WALT rip fence is recommended.

POCKET CUTTING (FIG. 14)
WARNING: Never tie the
lower blade guard in a raised
position. Never move the saw
backwards when pocket cutting.
This may cause the saw to raise
up off the work surface, which
could cause injury.
A pocket cut is one that is
made in a floor, wall or other
flat surface.
1. Adjust the saw shoe so
the blade cuts at desired
depth.
2. Tilt the saw forward and rest front of the shoe on material to be cut.
3. Using the lower blade guard retracting lever, retract the lower
blade guard to an upward position. Lower the rear of the shoe until
the blade teeth almost touch the cutting line.
4. Release the lower blade guard (its contact with the work will keep
it in position to open freely as you start the cut). Remove your
hand from the lower blade guard retracting lever and firmly grip
the auxiliary handle, as shown in Figure 14. Position your body and
arm to allow you to resist kickback if it occurs.
5. Make sure blade is not in contact with cutting surface before
starting saw.
6. Start the motor and gradually lower the saw until its shoe rests flat
on the material to be cut. Advance saw along the cutting line until
cut is completed.
7. Release the trigger switch and allow the blade to stop completely
before withdrawing the blade from the material.
8. When starting each new cut, repeat the above steps.
