OPERATION
SWITCH
See Figure 2.
To turn your hammer drill ON, depress the switch trigger.
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. The
direction of chuck rotation is controlled by a lever located
above the switch trigger. With your drill held in normal
operating position, the rotation lever should be positioned to
the left of the switch for drilling. 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
THE SWITCH LEVER IS PUSHED FULLY TO THE LEFT
OR RIGHT.
CHUCK KEY

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

When not in use, the chuck key can be placed in the storage
