OPERATION cont.
FORWARD / REVERSE LEVER (Fig. 5)
The direction of bit rotation, forward or reverse,
Fig. 5
is controlled by the lever above the trigger switch.
Always have the trigger switch in the OFF position
Reverse
when operating the forward / reverse lever.
1. For the Forward Bit Rotation the lever should be
to the left of the trigger switch (as you hold drill,
pointing forward, looking down), pointing to the
embossed arrow pointing forward towards
the chuck.
This forward position is used for Rotary drilling / driving and Hammer drilling.
2. To reverse Bit Rotation when in the Rotary drilling / driving mode only, move the lever to
the right of the trigger, pointing to the embossed arrow pointing towards the rear of the drill.
This reverse position is ONLY USED when rotary drilling / driving to back out screws and
jammed bits.
NOTE: The hammer drilling function will not operate for reverse hammering.
CAUTION:
To prevent gear damage, always allow the chuck to come to a
!
complete stop before changing the direction of rotation.
POWER LOCK-ON FEATURE (Fig. 6)
The Power Lock-On button is for use only when the hammer drill is mounted in a drill press
stand or otherwise held stationary. Do Not use the power lock-on feature when drilling or
driving by hand, so you can instantly release the trigger switch and stop the drill if the bit
binds in the hole or fastener. Be sure to release the power lock-on feature before
disconnecting the plug from the power supply. Failure to do so will cause the hammer drill
to start immediately the next time it is plugged in. Damage or injury could result.
The power lock-on feature, is convenient for
continuous drilling for extended periods of time.
To lock-on:
1. Depress the variable speed trigger switch.
2. Push in and hold the lock-on button, located on
the side of the drill's rear handle.
3. Release the variable speed trigger switch.
4. Release the power lock-on button and the drill will continue running at maximun speed.
5. To release the power lock-on, depress and release the variable speed trigger switch.
WARNING:
Before connecting the drill to a power supply source, always
!
check to be sure it is not in the power lock-on position by depressing and
releasing the variable speed trigger switch. Failure to ensure that it is not
locked-on could result in accidental starting of the drill, resulting in possible
serious injury. DO NOT lock the variable speed trigger switch in applications
where the drill may need to be suddenly stopped.

OPERATION cont.
360° AUXILIARY HANDLE (Figs. 7 and 7a)
The auxiliary handle clamps to the front of the gear case as shown (see Fig. 7).
It can be rotated 360° to allow either right or left hand use, providing maximum balance
and control in any operating position.
Forward
To assemble the
auxiliary handle onto
the drill, slide the clamp's
assembly collar
completely over and past
the chuck onto the front
of the drill's gear case
(see Fig. 7a) and tighten
by twisting the handle.
DEPTH STOP ROD (Fig. 8)
The Depth Stop Rod is used to control the
depth of a hole when you are not
through-drilling.
The depth stop rod mounts into the clamp's
assembly collar of the 360°auxiliary handle.
To adjust the depth stop rod, forward or
backwards, loosen the collar of the clamp
assembly by twisting the auxiliary handle
to loosen or tighten.
To adjust the depth stop rod for drilling to a
selected hole depth, move the rod so that
the distance between the end of the rod
and the end of the drill bit equals the
desired hole depth (see Fig. 8).
Fig. 6
When drilling, stop when the end of the depth stop rod touches the surface you're drilling in.
The depth stop rod is marked in inches, 1 through 7.
Lock-On
1/2-IN. KEYED STEEL CHUCK (Fig. 9)
The steel chuck is designed,
constructed and machined for
heavy-duty use, durability and long
service life.
Easily and securely install or remove
accessory bits using the chuck key
provided and the spindle lock on the
drill.
Apply a light coat of premium machine
oil to the surface of the chuck face and
jaws from time to time for rust
resistance.
