SWITCH
See Figure 2.

Release switch trigger to turn your hammer drill OFF.
LOCK-ON BUTTON
See Figure 2.
Your hammer drill is equipped with a "lock-on" feature, which
is convenient when continuous drilling for extended periods
of time is required. To lock-on, depress the switch trigger,
push in and hold the lock-on button located on the side of the
handle, then release switch trigger. Release lock-on button
and your drill will continue running. To release the lock,
depress the switch trigger and release it.
If you have the "lock-on" feature engaged during use and
your drill becomes disconnected from power supply,
disengage the "lock-on" feature immediately.
WARNING:
Before connecting your hammer drill to power supply
source, always check to be sure it is not in “lock-on”
position (depress and release switch trigger). Failure to
do so could result in accidental starting of your drill
resulting in possible serious injury. Also, do not lock the
trigger on jobs where your drill may need to be stopped
suddenly.
REVERSIBLE
See Figure 3.
Your hammer drill has the feature of being reversible in the
drill mode. The direction of chuck rotation is controlled by a
lever located above the switch trigger. With your drill held in
normal operating position, the direction of rotation lever
should be positioned to the left of the switch for drilling
operation. The direction of rotation is reversed when the
lever is to the right of the switch.
The design of the switch will not permit changing the direction
of rotation while the drill is running. Release the switch
trigger and allow the drill to stop before changing its direction.
NOTE: Your hammer drill will not run unless switch lever is
pushed fully to the left or right.
CAUTION:
Your hammer drill has not been designed for reverse
hammering. Failure to obey this warning may result in
property damage.

A chuck key has been provided for use when installing or
removing bits. It is also used when removing the chuck. (See
chuck removal section).
CHUCK KEY STORAGE
