RPM no load
On/Off Switch (Fig. A)
Saw is equipped with a switch lock-off feature to prevent
unintentional operation.
1. To operate the tool, press in on the lock-off button 
from either side of the saw and hold it in as you depress
the on/off switch 
.
2. After you have depressed the on/off switch and the
tool is running, release the lock-off button. The tool
will continue to run as long as the on/off switch
is depressed.
3. To turn the tool off, release the on/off switch.
nOTE: This tool has no provision for locking the tool on, and
the switch should never be locked on by any other means.

Automatic Electric Brake

Your saw is equipped with an electric blade brake which
stops the saw blade within 1–2 seconds of trigger release.
This is automatic and requires no adjustment.
Lower Blade Guard

WARNING: Laceration Hazard. The lower blade guard
is a safety feature which reduces the risk of serious
personal injury. Never use the saw if the lower guard
is missing, damaged, mis-assembled or not working
properly. Do not rely on the lower blade guard to
protect you under all circumstances. Your safety
depends on following all warnings and precautions
as well as proper operation of the saw. Check lower
guard for proper closing before each use as outlined
in Further safety instructions for all saws. If
the lower blade guard is missing or not working
properly, have the saw serviced before using. To assure
product safety and reliability, repair, maintenance and
adjustment should be performed by an authorized
service center or other qualified service organization,
always using identical replacement parts.

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle
material. Foreign objects in the workpiece such as wire
or nails can cause tips to crack or break. Only operate
saw when proper saw blade guard is in place. Mount
blade securely in proper rotation before using, and
always use a clean, sharp blade.

WARNING: To reduce the risk of injury, It is important
to support the work properly and to hold the
saw firmly to prevent loss of control which could
cause personal injury. Figure L illustrates typical
hand support.

Hints for Optimum Use
Pocket Cutting (Fig. A, N)

A pocket cut is one that is made when the edge of the
material does not push the lower guard open, but the
bottom edge of the rotating blade cuts into the middle of
the material.
WARNING: To reduce the risk of serious personal
injury, read, understand and follow all important
safety warnings and instructions prior to using tool.
WARNING: To reduce the risk of injury, remove the
battery, and follow all assembly, adjustment and set
up instructions.
Measure and mark work for cutting.
Support and secure work properly (refer to Supporting
Large Panels/Securing Workpiece).
Use appropriate and required safety equipment (refer to
Additional Safety Information).
Secure and maintain work area (refer to Safety
Instructions for All Saws).
With battery inserted, make sure switch turns saw on
and off.
WARNING: To reduce the risk of serious personal
injury, always hold the tool with both hands.
Keep your body positioned to either side of the blade,
but not in line with the saw blade. Kickback could cause
the saw to jump backwards. Refer to Further Safety
Instructions for all Saws and Kickback Causes and
Related Warnings.
Let the blade run freely for a few seconds before starting
the cut.
Apply only a gentle pressure to the tool while
performing the cut.
Work with the shoe pressed against the workpiece.
As some splintering along the line of cut on the top side
of the workpiece cannot be avoided, cut on the side
where splintering is acceptable.
Where splintering is to be minimized, e.g. when cutting
laminates, clamp a piece of plywood onto the top of
the workpiece.
WARNING: Never tie the blade guard in a raised
position. Never move the saw backwards when pocket
cutting. This may cause the unit to raise up off the
work surface which could cause injury.
