ADJUSTING THE TORQUE COLLAR
The clutch unit provides twenty clutch settings,
a "Drill" (solid lock-up) setting, and a hammer
(impact) position. Lowest torque is available at
setting #1, with maximum torque available at
the "Drill" setting. You can adjust the amount
of output torque by rotating the front collar
(A) Fig. 3, so that the desired torque setting is
aligned with the index mark (B) Fig. 3. Lower
torque settings are used for driving small
screws and other delicate work, while higher
torque settings are used for driving larger
screws. Use the "Drill" position for drilling and
for driving very large screws. Use the hammer position when "impacting" is
needed (concrete, bricks, etc).
TWO-SPEED GEAR SHIFT
The two-speed gear shift provides spindle
speed ranges of approximately 0-500 RPM
(LOW) and 0-1500 RPM (HIGH). To change
speed ranges, release the trigger switch to
stop motor. Slide the speed selector (A) Fig. 4
toward the rear for HIGH speed or toward front
for LOW speed.
The low speed position is normally used
when drilling larger holes and when driving or
removing screws. The high speed position is
normally used for drilling small holes.
DRIVER BIT STORAGE
Convenient storage areas with retaining clip (B) Fig. 4, for screwdriver bits are
located on each side of the tool.
CHARGING THE BATTERY PACK GENERAL
Before using your cordless tool for the first time, the battery pack should be
fully charged. If the battery pack is installed in the tool, remove it by following
instructions under INSTALLING OR REMOVING BATTERY PACK.
As a battery pack approaches the discharged state, you will notice a sharp drop
in tool performance. When the tool is unable to perform the task at hand, it is time
to recharge the battery pack. Recharging the battery pack before this condition is
reached will reduce the total work life of the pack. Discharging the pack beyond
this point can damage the pack.
NOTE: Battery temperature will increase during and shortly after use. Batteries
may not accept a full charge if they are charged immediately after use. Allow the
battery pack to cool to room temperature before charging for best results.
Do not operate the drill motor while installing or removing
bits. Operating the drill motor can cause bit to be thrown
