Protection Against
Deep Discharging
The lithium ion battery is protected against deep
discharging by the "Electronic Cell Protection
(ECP)" . When the battery is discharged, the tool
is switched off by means of a protective circuit.
Variable Speed Controlled Trigger
Switch
Your tool is equipped with a variable speed trig-
ger switch. The tool can be turned "ON" or "OFF"
by squeezing or releasing the trigger. The speed
can be adjusted from the minimum to maximum
nameplate RPM by the pressure you apply to
the trigger. Apply more pressure to increase the
speed and release pressure to decrease speed
(Fig. 1).
When the trigger switch is released it activates
the brake to stop the chuck quickly. This is espe-
cially useful in the repetitive driving and removal
of screws.
Forward/Reversing Lever
and Trigger Lock
After tool use, lock trigger
in "OFF" position to help
prevent accidental starts and accidental dis-
charge.
Your tool is equipped with a forward/reversing le-
ver and trigger lock 6 located above the trigger
(Fig. 10). This lever was designed for changing
rotation of the bit, and for locking the trigger in an
"OFF" position.
For forward rotation, (with chuck pointed away
from you) move the lever to the far left.
For reverse rotation move the lever to the far right.
To activate trigger lock move lever to the center
off position.
Do not change direction of
rotation until the tool comes
to a complete stop. Shifting during rotation of
the chuck can cause damage to the tool.
Gear Shifting
Your tool is equipped with two separate gear
ranges, low gear and high gear. Low gear pro-
vides high-torque and slower drilling speeds for
heavy duty work or for driving screws. High gear
provides faster speeds for drilling lighter work. To

change speeds slide switch, to the high or low
position (Fig. 1).
ATTENTION: If your tool appears to be running,
but the chuck will not turn, check to make sure
the gear shifting switch is pushed fully into de-
sired setting.
Adjustable Clutch
Your tool features 21 clutch settings. Output
torque will increase as the clutch ring, is rotated
from 1 to 20. The drill "
up the clutch to permit drilling and driving heavy
duty work (Fig. 1).
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).
