Plug charger cord into your standard power
outlet, then insert battery pack into charger
(
Fig. 5).
The charger’s green indicator light will begin to
“BLINK”. This indicates that the battery is
receiving a fast charge. Fast-charging will
automatically stop when the battery pack is
fully charged.
When the indicator light stops “BLINKING”
(and becomes a steady green light) fast
charging is complete.
The battery pack may be used even though
the light may still be blinking. The light may
require more time to stop blinking depending
on temperature. When you begin the
charging process of the battery pack, a
steady red light could also mean the battery
p
ack is too hot or too cold.
The purpose of the green light is to indicate
that the battery pack is fast-charging. It does
n
ot indicate the exact point of full charge.
The light will stop blinking in less time if the
battery pack was not completely discharged.
When charging several batteries in sequence,
the charge time may slightly increase.
When the battery pack is fully charged,
unplug the charger (unless you're charging
another battery pack) and slip the battery
pack back into the tool.

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.
DRIVING 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 bolt
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 then 0.5 Sec. Therefore, work with low
RPM and switch the machine off immediately
when the screw is tight and the impacting
sound can be heard.
For screwing larger, longer wood screws into
hard material, pre-drilling is the best method.
