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

• 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 off 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

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

Lubrication

Each time a Series QP Drill is disassembled for maintenance and repair or replacement of parts, lubricate the tool as follows:

1. Coat all exposed gears with Ingersoll Rand No. 67 Grease and work some of the Grease into the gearing of the Spindle Assembly (29).

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.

Disassembly

General Instructions

1. Do not disassemble the tool any further than necessary to replace or repair damaged
2. Whenever grasping a tool or part in a vise, always use leather- covered or copper-covered vice jaws to protect the surface of the part and help prevent This is particularly true of threaded members and housings.
3. Do not remove any part which is a press fit in or on a subassembly unless the removal of that part is necessary for repairs or
4. Do not disassemble the tool unless you have a complete set of gaskets and O-rings for

Disassembly of the Tool

Each Series QP Drill is made up using three modules or units which include a housing and throttle unit, a motor unit and a combined gearing and spindle unit. The tool can be disassembled for repairs to each individual unit without disturbing the other units. To separate the modules, proceed as follows:

1. Remove the Chuck (35) using the following technique:
2. Insert the short leg of a 1/4” hex wrench into the jaws of the Chuck and tighten the
3. Using a brass hammer, sharply rap the long leg of the wrench in a counterclockwise direction to loosen the
4. Unscrew and remove the Chuck from the
5. To separate the Gear Case (30) from the Housing (1), proceed as follows:
6. Install a standard 1-1/16” open end wrench on the flats of the Gear
7. Grasp the handle portion of the Motor Housing and rotate
8. Use Ingersoll Rand 10 Oil to lubricate the motor. Inject approximately 1 to 2 cc of oil into the air inlet before attaching the air hose to the tool.

After determining the actual velocity, shut off the air supply and insert a small jeweler’s screwdriver into the slot of the exhaust control plate screw and rotate the screw approximately fifteen 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 off the air supply when making adjustments to the screw.
