OPERATION

WARNING:

Make sure to insert the drill bit straight into the chuck

jaws. Do not insert the drill bit into the chuck jaws at

an angle then tighten, as shown in figure 7. This could

cause the drill bit to be thrown from the drill, resulting in

possible serious personal injury or damage to the chuck.

 Tighten the chuck jaws securely on the drill bit, using the

chuck key provided.

 Remove the chuck key.

TO REMOVE BITS

See Figure 6, page 12.

 Unplug the drill.

 Loosen the chuck jaws using the chuck key provided.

 Remove the drill bit.

 Remove the chuck key.

USING THE AUXILIARY HANDLE ASSEMBLY

See Figure 8, page 12.

The drill is equipped with an auxiliary handle assembly. For

ease of operation, use the handle with either the left or right

hand. The handle can be rotated 360°.

To adjust the auxiliary handle assembly,

 Loosen the handle assembly by turning the handle

counterclockwise.

 Rotate the auxiliary handle assembly to the desired

operating position.

 Securely tighten by turning the auxiliary handle clockwise.

Be sure the auxiliary handle is securely tightened against

the depth stop clamp. This secures the depth stop rod at

the desired depth of cut. It also secures the auxiliary handle.

NOTE: For convenience and ease of starting threads, the

hex nut has been trapped inside the molded slot in the

auxiliary handle.

The depth stop rod helps control the depth of drilled holes.

NOTE: When properly installed, the teeth on the depth stop

rod should be aligned with the teeth indicator on the depth

stop clamp.

Adjust the depth stop rod so that the drill bit extends

beyond the end of the rod to the required drilling depth.

When drilling holes with the depth stop rod installed, the

desired hole depth has been reached when the end of the

rod comes in contact with the surface of the workpiece.

SELECTING HAMMER MODE OR DRILLING

MODE

See Figure 9, page 12.

To adjust for type of drilling, slide the selector on top of the

motor housing to hammer mode or drilling mode. The ham-

mer mode symbol is on the right and the drill bit symbol is

on the left.

 Push in and hold the lock-on button, located on the side

of the handle.

 Release the switch trigger.

 Release the lock-on button and the drill will continue

running.

 To release the lock, depress and release the switch

trigger.

If the lock-on feature is engaged during use and the drill

becomes disconnected from the power supply, disengage

the lock-on feature immediately.

WARNING:

Before connecting the drill to a power supply source,

always check to be sure it is not in lock-on position (de-

press and release the switch trigger). 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 switch trigger in applications where the drill may need

to be suddenly stopped.

DIRECTION OF ROTATION SELECTOR

(FORWARD/REVERSE)

See Figure 5, page 12.

The direction of bit rotation is reversible and is controlled

by a selector located above the switch trigger. With the drill

held in normal operating position, the direction of rotation

selector should be positioned to the left of the switch trig-

ger for forward drilling. The drilling direction is reversed

when the selector is to the right of the switch trigger.

NOTICE:

To prevent gear damage, always allow the chuck to

come to a complete stop before changing the direction

of rotation.

To stop the drill, release the switch trigger and allow the

chuck to come to a complete stop.

NOTE: The drill will not run unless the direction of rotation

selector is pushed fully to the left or right.

Avoid running the drill at low speeds for extended periods

of time. Running at low speeds under constant usage may

cause the drill to become overheated. If this occurs, cool the

drill by running it without a load and at full speed.

TO INSTALL BITS

See Figures 6 - 7, page 12.

 Unplug the drill.

 Insert the chuck key and twist counterclockwise.

 Open or close the chuck jaws to a point where the open-

ing is slightly larger than the bit size you intend to use.

Also, raise the front of the drill slightly to keep the bit from

falling out of the chuck jaws.

 Insert the drill bit.
