Side Handle (Fig. B)
WARNING:
To reduce the risk of personal injury,
ALWAYS
operate the tool with the side handle
properly installed. Failure to do so may result in
the side handle slipping during tool operation and
subsequent loss of control. Hold tool with both hands
to maximize control.
The side handle can be placed in either side of the drill or
the top of the drill according to operator preference and
available working clearance. The spade handle can be
temporarily removed if working clearance at rear of tool is
limited. Always replace spade handle when possible.
Switch (Fig. A)
To start the drill, depress the trigger switch
1
; to stop the
drill, release the trigger.
A variable speed trigger switch permits speed control—the
farther the trigger is depressed, the higher the speed of the
drill.
NoTE:
Use lower speeds for starting holes without a center
punch, drilling in metal or plastics, driving screws or drilling
ceramics. Higher speeds are better for drilling wood and
composition boards and using abrasive and polishing
accessories.
The reversing lever
2
is used for withdrawing bits from
tight holes and removing screws. It is located above the
trigger switch. To reverse the motor, release the trigger
switch FIRST and then push the lever to the right. After any
reversing operations, return lever to forward position.
The locking feature
3
is for use when the drill is mounted in
a drill stand or otherwise firmly held…
NoT BY HaND.
Do not lock the switch “ON” when drilling by hand so that
you can instantly release the trigger switch if the bit binds
in the hole.
Be sure to release the switch locking button before
disconnecting the plug from the power supply. Failure to do
so will cause the tool to start immediately the next time it is
plugged in. Damage or injury could result.
Chuck
To insert bit, open chuck jaws by turning collar with fingers
and insert shank of bit about 3/4” (19 mm) into chuck.
Tighten chuck collar by hand. Place chuck key in each of the
three holes and tighten in clockwise direction. It’s important
to tighten chuck with all three holes.
To release bit, turn chuck key counterclockwise in just one
hole, then loosen the chuck by hand.
