Selecting the Drilling Mode (Fig. A)
•
For drilling in masonry, set the drilling mode selector to
the "hammer symbol"
•
For drilling in other materials and for fastening, set the
drilling mode selector to the "drill symbol"
Selecting the Direction of Rotation
For drilling and for tightening screws, use forward
(clockwise) rotation. For loosening screws or removing a
jammed drill bit, use reverse (counterclockwise) rotation.
nOTE: The direction of rotation is also depicted by an arrow
on the overmold of the tool near the forward/reverse
lever

.
Never change the direction of rotation while the motor
is running.
1. To select forward rotation, push the forward/reverse
lever to the right (when viewed from the chuck end).
2. To select reverse rotation, push the forward/reverse
lever to the left (when viewed from the chuck end).
Setting the Drilling Depth (Fig. A)
1. Slacken the side handle

2. Set the depth stop rod

The maximum drilling depth is equal to the distance
between the tip of the drill bit and the front end of the
depth stop rod.
3. Tighten the side handle by turning the grip
counterclockwise. Make sure that the side handle is
secure and does not slip.
Variable Speed Trigger Switch (Fig. A)
To turn the tool on, squeeze the trigger switch
the tool off, release the trigger switch. The variable speed
switch enables you to select the best speed for a particular
application. The more you squeeze the trigger, the faster
the tool will operate. Use lower speeds for starting holes
without a center punch, drilling in metals or plastics, or
driving screws. For maximum tool life, use variable speed
only for starting holes or fasteners.
nOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.

WARNING: The drill should only be locked ON
when it is held stationary in a drill press stand
or other means; NOT BY HAND! Never unplug the
tool with the locking feature engaged. To do so will
cause the tool to start immediately the next time it is
plugged in.
Drilling
•
Always unplug the drill when attaching or removing
accessories. When attaching accessories in the drill
chuck, it is important to securely tighten the chuck
using all three holes to prevent slippage. When using a
keyless chuck, hand tighten firmly.
•
Use sharp drill bits only.
•
Support and secure work properly, as instructed in the
Hammer Drill Safety Warnings.
•
Use appropriate and required safety equipment, as
instructed in the Hammer Drill Safety Warnings.
•
Secure and maintain work area, as instructed in the
General Power Tool Safety Warnings.
•
Run the drill very slowly, using light pressure, until the
hole is started enough to keep the drill bit from slipping
out of it.
•
Apply pressure in a straight line with the bit. Use
enough pressure to keep the bit biting but not so much
as to stall the motor or deflect the bit.
•
Hold the drill firmly with both hands to control its
twisting action. One hand should be placed on the
side handle.
•
Drills equipped with a side handle must use the
side handle.
•
If drill stalls, it is usually because it is being overloaded or
improperly used. Release trigger immediately, remove
drill bit from work, and determine cause of stalling. Do
not depress trigger on and off in an attempt to start a
stalled drill — this can damage the drill.
WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly to control the twisting action and avoid injury.
•
Minimize stalling on breakthrough by reducing pressure
and slowly drilling through the last part of the hole.
•
Keep the motor running while pulling the bit out of a
drilled hole. This will help reduce jamming.
Drilling in Wood
Holes in wood can be made with the same twist drill bits
used for metal or with spade bits. These bits should be
sharp and should be pulled out frequently when drilling to
clear chips from the flutes.
Drilling in Metal
Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry. The
cutting lubricants that work best are sulfurized cutting oil
or lard oil.
