Á WARNING:
For safety reasons, the operator must read the sections of this Owner’s Manual
ntitled “GENERAL SAFETY WARNINGS”, “POWER TOOL SAFETY”, “SPECIFIC
AFETY RULES”, “BATTERY & CHARGER SAFETY” and “SYMBOLS” before
using this drill.
Verify the following every time the hammer drill is used:
1. Safety glasses, safety goggles, or face shield is being worn.
2. Hearing protection and dust mask are being worn when drilling in concrete
3. The chuck has not worked loose on the spindle
4. The bit is in good condition, and is properly tightened into the chuck
Failure to observe these safety rules will significantly increase the risk of injury.
DRILLING
When drilling into smooth, hard surfaces such as metal, use a center punch to
mark the desired hole location. This will prevent the drill bit from slipping off
center as the hole is started.

(Y) Westinghouse
INNOVATION YOU CAN BE SURE OF
ASSEMBLY AND OPERATING
The workpiece to be drilled should be secured in a vice or with clamps to keep it
from turning as the drill rotates (Fig. 16)
1. Check the drill bit to make sure it is firmly locked into the drill chuck, and verify
that the forward/reverse switch is in the forward
2. Set the torque clutch to the drilling position
3. Hold the drill firmly with both hands whenever possible. Use one hand to grasp
the handle and switch end the other to grasp the body of the drill
NOTE: Make sure the hand placed on the body of the drill does not cover the air
vents. Covering these air vents will reduce motor cooling, and possibly lead to
overheating the motor.
4. While holding the drill firmly, place the point of the drill bit at the point to be
drilled. Squeeze the switch trigger to start the drill.
NOTE: Always use a higher drill speed when drilling small holes. Use a slower drill
speed when drilling large holes.
5. Move the drill bit into the workpiece applying only enough pressure to keep the
bit cutting. Do not force the drill bit or apply sideways pressure to elongate the
hole.
Á WARNING: Be prepared for binding and bit breakthrough. When these
situations occur, the drill bit has a tendency to grab the workpiece. This action
will kick the drill opposite to the direction of the drill bit rotation, and could
cause loss of control when breaking through material as you complete drilling
the hole. If you are not prepared, this loss of control can result in serious injury.
When drilling metals, use light oil on the drill bit to keep it from overheating. The
oil will prolong the life of the drill bit and improve the cutting action. If the bit jams
in the workpiece, or if the drill/stalls, release the trigger switch immediately.
Remove the bit form the workpiece and determine the reason for jamming.

DRIVING SCREWS
When driving screws, care must be taken to use the bit that correctly fits the
screw being driven. Make sure you use the largest bit size that will properly fit into
the head of the screw.
1. Select the correct screwdriver bit for the screw being driven
2. Fasten the screwdriver bit into the chuck, making sure the flat sides of the bit
are gripped by the chuck jaws
3. Set the torque clutch to the appropriate setting.
NOTE: If the workpiece material is particularly soft or porous, set the torque
clutch to a lower setting to avoid overdriving the screw.
4. If the screw is driven too far into the workpiece before the clutch releases, set
the clutch to a lower setting, and do not pull the trigger switch fully back. If the
screw is not driven far enough into the workpiece, set the clutch to a higher
setting.
NOTE: Do not continue to drive the screw once the clutch has released. This
causes unnecessary wear of the clutch
REMOVING A CHUCK
1. Remove the battery pack from the drill
2. Insert a 5/16” (8 mm) or larger hex key (1) into the chuck (2) and tighten the
chuck jaws securely (Fig. 17). Make sure each of the chuck jaws (3) is seated on
the flat surfaces of the hex key.
3. Tap the hex key sharply with a mallet (4) in clockwise direction. This action will
loosen the screw in the chuck for easy removal

After installing a chuck that has previously been removed, the chuck may become
loose on the spindle and develop a wobble. Also, the chuck screw may become
loose, causing the chuck jaws to bind and prevent them from closing. To tighten
the chuck, follow these steps:
1. Insert the hex key into the chuck and tighten thechuck securely
2. Tap the hex key sharply with a mallet in a CLOCKWISE direction (Fig. 20) This
will tighten the chuck on the spindle.
3. Open the chuck jaws and remove the hex key
4, Tighten the chuck screw using a #2(+) screwdriver.
NOTE: Turn the screw COUNTER-CLOCKWISE to tighten it. This screw has a
left-handed thread.

serious injury.
NICKLE-CADMIUM BATTERY MAINTENANCE
Nickle-cadmium batteries are powerful, rugged and provide hundreds of charge/-
discharge cycles if properly maintained and periodically “exercised”. Exercising is
required to recover most of the capacity lost during usage. This process reduces
the size of the active cadmium hydroxide crystals on the anode, to expose the
entire surface area and restore capacity.
How to care for your Nickle-cadmium battery
1. Never allow a battery to freeze.
2. Do NOT charge a battery when the work area or the battery temperature is at or
below O*C (32°F) or above 45°C (113°F). Allow it to sit at room temperature for at
least 30 minutes before charging.
3. Do not charge a battery if it feels warm to the touch
4. Never charge a battery after a short use. Let it sit until it is needed again
5. Never charge the battery until the tool in which it is being used cannot produce
useful work.
HOW TO EXERCISE A NICKLE-CADMIUM BATTERY
NOTE: Ni-Cd and Ni-Mh batteries have a self-discharge rate of approximately 1%
per day. The self-discharge rate depends upon the temperature.
1. Every two months or after 30 charge/discharge cycles, whichever comes first,
fully discharge your battery. To fully discharge the battery, place it in the tool that
it came with and work with the tool until it nearly stops and no longer produces
useful action.
2. If the tool came in a kit with a worklight insert the battery into the light. Turn the
switch ON and leave it ON until the filament is cherry read.

3. Let the battery rest for 30 minutes at room temperature 21°C (70°F) before
charging
4. Charge the fully discharged battery for approximately 1 hour at 21°C (70°F).
