Bit Selection
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are many
the information on the bit's packaging for proper
usage.
• Do not use bits larger than the rated capacity of the
drill. Gear damage or motor overload may result
Installing Bits
Always remove the battery before inserting or remov-
ing bits. Select the proper style and size bit for the
application.
Installing Bits into Keyed Chucks
1.
Remove the battery pack.
2.
Open the chuck jaws wide
enough to insert the bit. Be
sure the bit shank and chuck
jaws are clean. Dirt particles
may prevent the bit from lining
up properly.
3. Insert the bit into the chuck.
Centre the bit in the chuck
jaws and lift it about 1/16" off of the bottom. Tighten
the chuck jaws by hand to align the bit.
4.
Place the chuck key in each of the three holes in
the chuck, turning it clockwise to tighten the chuck
securely.
NOTE: Never use a wrench or means other than
a chuck key to tighten or loosen the chuck.
5.
To remove the bit, insert the chuck key into
one of the holes in the chuck and turn it counter-
clockwise.
Installing Bits into 7/16" Hex
QUIK-LOK™
1. Remove the battery pack.
2.
To attach an accessory, press the shank into the
hex drive QUIK-LOK™chuck.
3.
To remove the accessory, pull out the QUIK-
LOK™chuck ring and remove the accessory.
Release the ring.
Side Handle
The side handle can be installed on either side of the
tool. To install the side handle, thread it into the socket
on the desired side of the tool and tighten it securely.
OPERATION
To reduce the risk
WARNING
wear proper eye protection marked
to comply with AS:NZS 1336:2014.
When working in dusty situations, wear
appropriate respiratory protection or use an
appropriate dust extraction solution.
Bit binding
If the bit binds, the drill will suddenly react in the
opposite direction of the rotation of the bit. Reduce
the chances of a sudden reaction by following the
instructions listed below. Prepare for a sudden reac-
tion by holding or bracing securely.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are many types
Chuck
of injury, always
• Keep selfeed bits aligned with the work surface so
bits go in straight (see "Drilling").
• Avoid drilling warped, wet, knotty, and/or pitchy
material if possible.
• Avoid drilling in material that you suspect contains
hidden nails or other things that may cause the bit
to bind.
The direction of reaction is always opposite of the
direction of bit rotation. Reaction is even more likely
to occur when enlarging already existing holes and
at the point when the bit breaks through the other
side of the material.
If the bit does bind:
1. Release the trigger immediately.
2. Reverse the motor.
3. Remove the bit from the work and start again.
4. Do not pull the trigger on and off to attempt to start
a stalled bit. This will damage the drill.
Bracing for forward rotation
When drilling in forward, the bit will rotate in a clock-
wise direction. If the bit binds in the hole, the bit will
come to a sudden stop and drill will suddenly react
in a counterclockwise direction.

A. Forward (clockwise) rotation
B. Reaction
C. Brace drill with motor housing here
If the bit binds, the motor housing braced against the
stud will hold the drill in position.

Bracing for reverse rotation
When drilling in reverse, the bit will rotate in a coun-
terclockwise direction. If the bit binds in the hole,
the bit will come to a sudden stop and the drill will
suddenly react in a clockwise direction.
