RIDGID R841151 Drill User Manual


 
13
This drill has an electric brake. When the trigger switch is
released, the chuck stops turning. When the brake is
functioning properly, sparks will be visible through the vent
slots on the housing. This is normal and is the action of the
brake.
Note: You might hear a whistling or ringing noise from the
switch during use. Do not be concerned, this is a normal part
of the switch function.
REVERSIBLE
See Figure 4.
This tool has the feature of being reversible. The direction of
rotation is controlled by a selector located above the switch
trigger. With the drill held in normal operating position, the
direction of rotation selector should be positioned to the left
of the switch for drilling. The drilling direction is reversed
when the selector is to the right of the switch. When the
selector is in center position, the switch trigger is locked.
CAUTION:
To prevent gear damage, always allow chuck to
come to a complete stop before changing the direc-
tion of rotation or the two speed gear train (hi-lo).
To stop, release switch trigger and allow the chuck to
come to a complete stop.
TWO-SPEED GEAR TRAIN
See Figure 7.
Your 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 your 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.
AUXILIARY HANDLE
See Figure 8.
An auxiliary handle is packed with the drill for ease of opera-
tion and to help prevent loss of control.
To use the auxiliary handle:
Open the clamping ring by turning the handle counter-
clockwise.
Slide the ring of the auxiliary handle onto the spindle collar
of the machine.
Tighten the auxiliary handle at the desired angle by
turning the handle clockwise.

To prevent thread damage and possible loss of control, the
auxiliary handle should be checked periodically for tightness.
Do not operate the drill with the handle loose.
