CAUTION:
When using the tool as a spotlight, be sure
it is secured on a stable surface where it will not cause a
tripping or falling hazard.
CAUTION:
Remove all accessories from the chuck before
using the drill as a spotlight. Personal injury or property
damage could result.
Low Battery Warning
When in spotlight mode and the battery is nearing complete
discharge, the spotlight will flash twice and then dim. After two
minutes, the battery will be completely discharged and the
drill will immediately shut down. At this point, replace with a
fresh battery.
WARNING:
To reduce the risk of injury, always have a
back-up battery or secondary lighting available if the
situation warrants it.
Performing an Application (Fig. A, C)
WARNING: To reduce the risk of personal injury,
ALWAYS
ensure workpiece is anchored or clamped firmly.
WARNING:
Always wait until the motor has come to
a complete standstill before changing the direction
of rotation.
Prior to performing work:
• Set the speed selector
6
. Refer to
Speed Selection
.
• Install the appropriate bit or accessory into the chuck. Refer
to
Installing a Bit or Accessory into a Keyless Chuck
.
WARNING:
• Do not use this tool to mix or pump easily combustible
or explosive fluids (benzine, alcohol, etc.).
• Do not mix or stir flammable liquids
labeled accordingly.
Screwdriving
Your tool has a clutch with adjustable torque for driving
and removing a wide array of fastener shapes and sizes. The
numbers on the mode selection collar
5
are used to set a
torque range for screwdriving. The higher the number on the
collar, the higher the torque and the larger the fastener which
can be driven.
1. Turn the mode selection collar
5
to the desired position.
Refer to
Mode Selection
.
2. Pull the trigger switch applying pressure in a straight line
with the bit until the fastener is seated at the desired depth
in the workpiece.
Recommendations for screwdriving
• Start with lower torque settings, then advance to higher
torque settings to avoid damage to the workpiece
or fastener.
• Make some practice runs in scrap or on unseen areas of the
workpiece to determine the proper position of the mode
selection collar.
Drilling
1. Turn the mode selection collar
5
to the drill symbol. Refer
to
Mode Selection
.
2. Place drill bit in contact with the workpiece.
nOTE:
Use sharp drill bit only.
3. Pull the trigger switch applying pressure in a straight line
with the bit until it reaches the desired depth.
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.
4. Keep the motor running when pulling the bit back out of a
drilled hole to prevent jamming.
Recommendations for Drilling
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect the bit.

-
To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of the hole.
• Large holes (7.9 mm to 12.7 mm) in steel can be made
easier if a pilot hole (4 mm to 4.8 mm) is drilled first.
• If drilling thin material or material that is prone to splinter,
use a wood “back-up” block to prevent damage to
the work piece.
