Drill only action: For drilling in woods,
metals, plastics or other non concrete
materials. The drill position overrides the
clutch for drilling.
Drill with hammer action: For drilling in
concrete, asphalt, tile or other similar hard
materials. The hammer drill position
overrides the clutch for hammer drilling.
Autolock™
Your tool is equipped with an automatic
locking system. This feature will lock the
bit holder in one position when the trigger
switch is released. This will allow you to
tighten or loosen a nut or screw by rotating
the tool by hand with the switch off. This is
convenient when higher turning torque is
needed.
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).
Battery Charge Condition
Indicator Lights
Your tool is equipped with charge condition
indicator lights (Fig. 1). The indicator lights
shows the charge condition of the battery
for a few second when the On/Off trigger is
pressed halfway or fully.

Operating Tips
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 oper a tion, 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.
DRIVING NUTS AND BOLTS
Variable speed control must be used with
caution for driving nuts and bolts with
socket set attach ments. The technique is to
start slowly, increasing speed as the nut or
bolt runs down. Set the nut or bolt snugly
by slowing the drill to a stop. If this
procedure is not followed, the tool will
have a tendency to torque or twist in your
hands when the nut or bolt seats.
DRILLING
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 oper a tion, 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 switch trigger with variable speed
adjustment helps in maintaining control of
the tool. When the drill bit starts to remove
material, speed of the drill bit may be
increased by squeezing the trigger.
DRIVING WITH VARIABLE SPEED
Variable speed drills will double as a power
screwdriver by using a screwdriver bit.
Prior to driving screws, pilot and clearance
holes should be drilled. Place the threaded
end of the screw in the pilot or clearance
