ACCESSORY HOLDER
Install the accessory holder securely in the groove of the drill
and tighten the screw to fix the holder firmly. (Fig. G) A bit
may be stored on the accessory holder by snapping it into
place.
TEMPERATURE CUT-OUT
When used as intended, the driver cannot be subjected to
overload. But running continuously at full load for a long
time will cause the battery pack to overheat. If the allowable
battery temperature range of 32–158
o
F (0–70
o
C) is exceeded,
the battery pack will automatically stop operating and will not restart until it has cooled
to a safe level.
LOW-VOLTAGE CUT-OUT
The battery pack used on this tool is fitted with a low voltage cut out feature within
the circuitry. The low-voltage cut-out feature operates when the voltage drops below
a pre-set value. This feature automatically stops the tool from operating. When this
condition occurs you will need to either insert another battery pack into the tool or
recharge the existing battery pack.
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 starting the tool. 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.
OPERATING INSTRUCTIONS
DRIVING SCREWS WITH VARIABLE SPEED
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. Always hold the machine straight on the screw to be tightened.
The best method to determine the right impacting/tightening duration is by means of
a trial. For small screws, the right impacting/tightening duration can be reached in less
than 0.5 sec. Therefore, work with low RPM and switch the machine off immediately
when the screw is tight and the impacting sound is heard.
For screwing larger, longer wood screws into hard material, pre-drilling is the best
method.
TIGHTENING TORQUE
The tightening torque depends on the duration of the impacting/tightening action.
The largest tightening torque is achieved after approx. 6 to 10 seconds of impacting/

For middle or soft joining cases, the maximum tightening torque is less than for hard
cases. Therefore, a longer impacting/tightening action is necessary to arrive at the
maximum tightening torque.

refrigerator or freezer. To reduce the temperature of the cells
remove the battery pack from the tool and place the battery pack
in a free air environment, out of direct sunlight or any other heat
source.
NOTE: Attempting to restart the tool without either recharging
the battery or installing another battery (with charge) will lead to
tool restarting and then stopping again, after only a few seconds of
operation.
