Maintenance - RIDGID R86009 Operator's Manual

OPERATION
NOTICE:
Never change speeds while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
ADJUSTING TORQUE
See Figure 9, page 11.
When using the drill for various driving applications, it be-
comes necessary to increase or decrease the torque 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 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.
DRILLING/DRIVING SCREWS
See Figure 10, page 11.
WARNING:
Always use the auxiliary handle when using this
tool to help resist torque reactions. Binding or
stalling of this product could lead to serious
personal injury.
 Install the auxiliary handle.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Use LO (1) speed for high torque applications and
HI (2) speed for fast drilling or driving applications. Refer
to Hi-Lo Speed Switch and Adjusting Torque.
 Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
 Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
WARNING:
Do not drive a screw where there is likely to be
hidden wiring behind the surface. Contact with a
"live" wire will make exposed metal parts of the tool
"live" and possibly shock the operator. If you must
drive a screw where hidden wire may be present,
always hold tool by insulated gripping surfaces
(handle) when performing the operation to prevent
a shock to the operator.
 Depress the switch trigger to start the drill.
NOTE: Maintenance information begins on page 8 after French
and Spanish language sections. Illustrations start on page 9.

 Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING:
When drilling, be prepared for binding at bit
breakthrough. When these situations occur, drill
has a tendency to grab and kick opposite to the
direction of rotation and could cause loss of control
when breaking through material. If not prepared, this
loss of control can result in possible serious injury.
 With hard, smooth surfaces, use a center punch to mark
the desired hole location. This will prevent the bit from
slipping off-center as the hole is started.
 If the bit jams in the workpiece or if the drill stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
NOTE: This drill has an electric brake. When the switch trig-
ger 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.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
 Increase the speed as the drill bit bites into the material.
 When drilling through holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
Metal and Steel Drilling
 Use a light oil on the drill bit to keep it from overheating.
The oil will prolong the life of the bit and increase the
drilling action.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit.
