TEMPERATURE OVERLOAD
PROTECTION
Avoid using battery
continuously, for long periods of time, while
subjecting the tool to overload conditions, such
as drilling with large diameter accessories into
hard materials. Using battery powered tools at
extreme loads, may cause the battery to
exceed its allowable operating temperature
range. When the battery exceeds normal
operating temperature caused by overload, the
speed of the tool may be reduced and the tool
may appear to lose power. To regain the tool's
full performance, the battery must be allowed
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 variable speed trigger allows you to slowly
increase RPM. By using a slow starting speed,
you are able to keep the bit from "wander ing".
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
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 hole and start driving
the screw slowly, increasing the speed as the
screw runs down. Set the screw snugly by
slowing to a stop.
FASTENING WITH SCREWS
The procedure shown in Fig. 12 will enable
you to fasten materials together using your
drill without stripping, splitting or separating
the material.
to cool, until the operating temperature returns

RAPID SHUT-OFF (KICK BACK CONTROL)
To ensure better control of the tool during
operation, this tool is design to shut-off while in
use if a sudden or unexpected bind up
situation occurs. Bind up occurs when the bit
gets jammed during operation, which forces
the bit to stop spinning abruptly. If this occurs,
the tool will shut down and the Rapid Shut-off
will be indicated by a flashing LED on the tool.
This feature can only be activated when the
tool is running at maximum speed.
Operating Tips
First, clamp the pieces together and drill the
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
hole in the top piece of wood again to the
same diameter as the shank of the screw.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Realign the holes on the two pieces
and apply even pressure when driving the
screw. The screw shank clearance hole in
the first piece allows the screw head to pull
the pieces tightly together.
The adjustable screw drill accessory will do
all of these operations quickly and easily.
Screw drills are available for screw sizes No.
