WARNING
Do not hold the chuck with one hand and use the power
of the drill to tighten the chuck jaws on the drill bit. The
chuck body could slip in your hand, or your hand could
slip and come in contact with the rotating drill bit. This
could cause an accident resulting in serious personal
injury.
TWO-SPEED GEAR TRAIN (HI-LO)
The drill has a two-speed gear train designed for drilling
or driving at LO (1) or HI (2) speeds. A slide switch is
located on top of the drill to select either LO (1) or HI (2)
speed. When using drill in the LO (1) speed range, speed
will decrease and unit will have more power and torque.
When using drill in the HI (2) speed range, speed will
increase and unit will have less power and torque. Use LO
(1) speed for high power and torque applications and HI
(2) speed for fast drilling or driving applications.
NOTE:
to the other, turn the chuck by hand until the gears engage.
CAUTION
Never change gears while the tool is running. Failure
to obey this caution could result in serious damage to
the drill.
QUICK MODE SELECTOR
The Quick Mode Selector allows you to quickly switch
from drill mode to drive mode.
In general, drill mode should be used for drilling and other
heavy duty applications. Drive mode should be used for
driving screws. Hammer mode should be used for impact
drilling.
TORQUE ADJUSTMENT
When using the drill-driver for various driving applications,
it becomes necessary to increase or decrease the torque
in order to help prevent the possibility of damaging
screw heads, threads, workpiece, etc. In general, torque
intensity should correspond to the screw diameter. If the
torque is too high or the screws too small, the screws may
be damaged or broken.
The torque is adjusted by rotating the torque adjustment ring.
The torque is greater when the torque adjustment ring is
set on a higher setting. The torque is less when the torque
adjustment ring is set on a lower setting.
English
The proper setting depends on the type of material and the
size of screw you are using.
BIT STORAGE
When not in use, bits provided with the drill can be placed
in the storage areas located on the base of the drill.
SELECTING DRIVE OR DRILL SETTING
Using the chart below, choose correct speed and mode,
the type of bit, fastener, and material you will be using.
Choose your APPLICATION
Choose the correct SPEED: (1/LOW or 2/HIGH)
Choose the correct MODE: (DRIVE, DRILL, OR
HAMMER)
INSTALLING BITS
Lock the switch trigger by placing the rotation selector
in the center position.
Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend to
use. Also, raise the front of the drill slightly to keep the
bit from falling out of the chuck jaws.
Insert the drill bit.
Tighten the chuck jaws on the drill bit.
Make sure to insert the drill bit straight into the chuck
jaws. Do not insert the drill bit into the chuck jaws at
an angle then tighten. This could cause the drill bit to
be thrown from the drill, resulting in possible serious
personal injury or damage to the chuck.
NOTE: Rotate the chuck body in the direction of the arrow
marked LOCK to tighten the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
REMOVING BITS
Lock the switch trigger by placing the rotation selector
in the center position.
Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the
arrow marked UNLOCK to loosen the chuck jaws. Do
not use a wrench to tighten or loosen the chuck jaws.
Remove the drill bit.
