Product Safety Information

WARNING

Failure to observe the following warnings, and to avoid these potentially hazardous situations, could result in death or serious

•

injury.
Read and understand this and all other supplied manuals before installing, operating, repairing, maintaining, changing accessories

•

on, or working near this product.
Always wear eye protection when operating or performing maintenance on this tool. The grade of protection required should be

•

assessed for each use and may include impact-resistant glasses with side shields, goggles, or a full face shield over those glasses.
Always turn o the air supply, bleed the air pressure and disconnect the air supply hose when not in use, before installing, removing

•

or adjusting any accessory on this tool, or before performing any maintenance on this tool or any accessory.

Note: When reading the instructions, refer to exploded diagrams in parts Information Manuals when applicable (see under Related Documentation

for form numbers).

Lubrication

Use Ingersoll Rand No. 10 Oil to lubricate the motor.
Each time a Series QP Drill is disassembled for maintenance and
repair or replacement of parts, lubricate the tool as follows:

Coat all exposed gears with Ingersoll Rand No. 67 Grease

1.

and work some of the Grease into the gearing of the Spindle
Assembly (29).

2.
Inject approximately 1 to 2 cc of oil into the air inlet before
attaching the air hose to the tool.

Speed Adjustment

Series QP Drills are furnished with the ability to precisely control,
within certain ranges, the optimum drilling speed for exotic
materials. Setting the speed requires a tachometer and a jeweler’s
screwdriver. Therefore, the adjustment, although simple, should
only be attempted by a competent technician using the proper
equipment.

A small, round opening is located adjacent to the Inlet Bushing
Assembly (4) in the molded exhaust vent. A tiny screw at the bottom
of that hole controls the location of the exhaust control plate. Take
an initial reading of the tool speed by applying a tachometer to the
end of the Chuck without a drill bit and with the trigger completely
depressed. If the tachometer has a concave tip, close the chuck
completely; if the tip is convex, open the chuck completely.

After determining the actual velocity, shut o the air supply and
insert a small jeweler’s screwdriver into the slot of the exhaust control
plate screw and rotate the screw approximately fteen degrees.
Restore the air supply and check the velocity again. The control plate
provides unrestricted exhaust for 90 degrees, completely restricted
exhaust for 90 degrees and variable, adjustable exhaust for 180
degrees. Determine which direction you need to rotate the screw
to obtain the desired speed and then move the screw accordingly.
Best results are achieved by using gradual increments and frequent
tachometer readings. Be sure to turn o the air supply when making
adjustments to the screw.

Disassembly
