When the trigger switch is released it
activates the brake to stop the chuck quickly.
This is especially useful in the repetitive
driving and removal of screws.
Set Forward/Reversing lever to the center (off
position). Slide charged battery pack into the
housing until the battery pack locks into
position (Fig. 8).
Your tool is equipped with a secondary locking
latch to prevent the battery pack from
completely falling out of the handle, should it
become loose due to vibration.

You will extend the life of your bits and do
neater work if you always put the bit in
contact with the work before pulling the
trigger. During the operation, hold the tool
firmly and exert light, steady pressure. Too
much pressure at low speed will stall the tool.
Too little pressure will keep the bit from
cutting and cause excess friction by sliding
over the surface. This can be damaging to
both tool and bit.
DRILLING WITH VARIABLE SPEED
The trigger controlled variable speed feature
will eliminate the need for center punches in
hard materials. The variable speed trigger
allows you to slowly increase RPM. By using
a slow starting speed, you are able to keep
the bit from "wandering". You can increase
the speed as the bit "bites" into the work by
squeezing the trigger.
DRIVING WITH VARIABLE SPEED
Variable speed drills will double as a power

Operating Tips
BUILT IN WORK LIGHT
Your tool is also equipped with a light that turns
on automatically when the switch is activated,
for better visibility when drilling/driving (Fig. 1).
To remove the battery pack, press the battery
pack release button and slide the battery pack
forward (Fig. 9).
Press the battery pack release button again
and slide the battery pack completely out of
tool housing (Fig. 9).

screwdriver by using a screwdriver bit in the
drill mode. The technique is to start slowly,
increasing the speed as the screw runs
down. Set the screw snugly by slowing to a
stop. Prior to driving screws, pilot and
clearance holes should be drilled.
FASTENING WITH SCREWS
This procedure shown in (Fig. 10) will enable
you to fasten materials together with your
Cordless Drill/Screwdriver without stripping,
splitting or separating the material.
First, clamp the pieces together and drill the
first hole 2/3 the diameter of the screw. If the
material is soft, drill only 2/3 the proper
length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the
second hole the same diameter as the screw
shank in the first or top piece of wood.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
