The Bosch
model
PS20 Cordless
Drill/Driver
has a chuck that accepts any 1/4" hex bit. The
low
RPM capability
of this model
is not a
deficiency.
On the contrary,
low speed means
high torque and high torque is a definite plus for
efficient drilling and driving. The low speed also
provides more control to prevent stripout of the
screw and damage to the work surface.
INSERTING AND REMOVING ACCESSORIES
To
avoid
loss
of control,
ensure
bit is locked in chuck
by pulling on bit after it has been inserted.
Your tool is equipped
with
a quick
release
chuck.
To insert
an accessory,
simply
pull
locking sleeve forward, insert desired accessory
into chuck
until the locking
sleeve
retracts
automatically,
locking the bit (Fig. 2).
To remove
an accessory,
pull locking
sleeve
forward and simply remove it from the chuck.
One inch
bits should
only
be used
along
with a bit holder as shown
in figure 2.
TRIGGER CONTROLLED
VARIABLE SPEED
Your tool is equipped
with a variable
speed
trigger switch. The tool speed can be controlled
from minimum
to maximum
nameplate
rated
RPM by the pressure you apply to the trigger.
Apply more pressure to increase the speed and
release pressure to decrease speed (Fig. 1).
BRAKE
When the trigger switch is released it activates
the brake to stop the chuck
quickly.
This is
especially
useful in the repetitive
driving
and
removal of screws.
FORWARD/REVERSING
LEVER
& TRIGGER
LOCK
Your
tool
is equipped
with
a forward/
reversing lever and trigger lock located above
the trigger (Fig. 3). This lever was designed
for
-g-
changing
rotation of the chuck, and for locking
the trigger in an "OFF" position to help prevent
accidental
starts
and accidental
battery
discharge.
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.
ADJUSTABLE CLUTCH
Your tool features 10 clutch settings. Output
torque will increase as the clutch ring, is
rotated from 1 to 10. The Drill ",lllu"
position
will lock up the clutch to permit drilling and
driving heavyduty work (Fig. 4).
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. 4).
