Safety Recommendations
For your safety and the safety of others, read and understand
the safety recommendations and operating instructions before operating any drill motor.
!
• Before the tool is connected to the air supply, the throttle
should be checked for proper operation (i.e., throttle valve
moves freely and returns to closed position).
Always wear protective equipment:
!
WARNING
• Before removing a tool from service or changing drill bits,
make sure the air line is shut off and drained of air. This will
prevent the tool from operating if the throttle is accidently
engaged.
Impact resistant eye protection
must be worn while operating
or working near this tool.
For additional information on eye protection, read the latest edition
of ANSI Z87.1, Occupational and Educational Eye and Face
Protection. This standard is available from the American National
Standards Institute, Inc., 11 West 42nd Street, New York, N.Y.
10036.
!
CAUTION
CAUTION
• Cutting tools used with these drill motors are sharp.
Handle them carefully to avoid injury.
• The collet and mandrel must be inserted into a properly
sized pre-drilled hole before starting the tool. An improperly sized pre-drilled hole prevents the mandrel from
engaging the collet and could result in slippage of the tool.
An improperly selected collet and mandrel can also result
in slippage of the tool.
Personal hearing protection is
recommended when operating
or working near this tool.
!
Hearing protection is recommended in high noise areas (above
85dBA). Close proximity of additional tools, reflective surfaces,
process noises, etc., can contribute substantially to the sound
level experienced by the operator.
!
WARNING
Wear respirator where
necessary.
Drilling or other use of this tool may produce hazardous fumes
and/or dust. To avoid adverse health effects, utilize adequate
ventilation and/or a respirator. Read the material safety data
sheet of any cutting fluids or materials involved in the drilling
process.
!
Do not wear loose fitting clothes,
long hair, gloves, ties or jewelry.
Follow good machine shop practices. Rotating shafts and moving
components entangle and entrap, and may result in serious
injuries. Never wear long hair, loose-fitting clothes, gloves, ties,
or jewelry when working with or near a drill of any type.
Quackenbush drills are designed to operate on 90psig (6.2 bar)
maximum air pressure using the proper size hose. Excessive air
pressure increases the loads and stresses on tool parts and drills,
and may result in breakage. The installation of a filter-regulatorlubricator in the air supply line ahead of the tool is highly recommended.

Safety Labels
WARNING
Exposure to vibration can
injure your hands and arms.
Some individuals are susceptible to disorders of the hands and
arms when exposed to vibration and/or tasks which involve
repetitive work motions. Those individuals predisposed to vasculatory or circulatory problems may be particularly susceptible.
Cumulative trauma disorders such as carpal tunnel syndrome and
tendinitis can be caused or aggravated by repetitious, forceful
exertions of the hands and arms. These disorders develop gradually over periods of weeks, months, and years. Tasks should be
performed in such a manner that the wrists are maintained in a
neutral position, which is not flexed, hyperextended, or turned side
to side. Stressful postures should be avoided and can be controlled through tool selection and work location.
Any tool operator should be aware of the following warning signs
and symptoms so that a problem can be addressed before it
becomes a debilitating injury. Any user suffering from prolonged
symptoms of tingling, numbness, blanching of fingers, clumsiness
or weakened grip, inability to hold objects, nocturnal pain in the
hand, or any other disorder of the shoulders, arms, wrists, or
fingers should notify their employer so that a review of what steps
might be taken to prevent further occurances. These steps might
include but are not limited to, repositioning the workpiece or
redesigning the workstation, reassigning tool users to other jobs,
rotating jobs, changing worker pace, and/or changing the type of
tool used so as to minimize stress on the operator. Some tasks
may require more than one type of tool to obtain the optimum
operator/ tool/ task relationship.
The safety labels found on this tool are an essential part of this
product. Labels should not be removed. Labels should be checked
periodically for legibility. Replace safety labels when missing or
when the information can no longer be read. Replacement labels
can be ordered by the part numbers shown on this page.

Introduction and General Information
The Q-Matic nut plate drill motor has been developed for
drilling an countersinking the two holes required for attachment of nut plate fasteners.
Utilizing an air/hydraulic system, and expanding collet grips
the work with 240 lbs. holding force during the complete drilling
and countersinking operation.
The air powered motor develops 1HP and consumes 35 CFM
at 90 psi, the recommended air line pressure. The tool developes
200 lbs. of drilling thrust, and is capable of drilling holes up to
.128 in. diameter in aluminum. Total feed stroke is .562 in.;
maximum colleting stroke is .400 in.
Each Q-matic nut plate drill can be used to drill holes for all
three types of nut plate fasteners: single wing, double wing and
Mickey Mouse. By simply changing the front bearing support
block, lift finger and pressure foot, one tool can be used for all
types of nut plate fasteners. This feature eliminates the need
for a specific tool to drill and countersink the varied nut plate
configuration.
Depth Control
Individual spindle adjustment knobs located at the rear of the
tool controls the countersink depth accuracy to within + or .001 in.
Depending upon the hardness of the material being drilled,
drilling cycle time can be adjusted from 1.5 sec. to 34 sec. by
means of an externally mounted feed control valve.
The Q-Matic nut plate drill is available in three speed models:
600 rpm, 6,000 rpm and 20,000 rpm. An adjustable throttle
control valve located in the handle enables the tool spindle
speed to be reduced as much as 50%, allowing the tool rpm to
be matched to the material being drilled, thereby providing
optimum drill bit life.
An optional externally mounted pneumatic booster pump is
available for use on the 600 rpm models. This optional pump
increases both thrust and clamping force of the tool by as much
as two and one-half times.
Tool Start-Up
The Q-Matic nut plate drill motor is shipped from the factory
equipped to the customer's specifications; spindle RPM, nut
plate styles, drill spindle spacing and optional booster pump (if
needed). Collets, mandrels and drills can be supplied for
customers with start-up nut plate drilling applications.
After unpacking, examine the customer specified equipment
on the Q-Matic tool to verify style and size of components.
Attach air line to 1/4" NPT inlet bushing. If 1/4" quick disconnect plugs are minimum recommended size for standard units
and 3/8" quick disconnect fittings are minimum recommended
size for units with booster pumps, the recommended air hose
size is 3/8" inside diameter equipped with in-line filter and
lubricator.
With air line attached, pull trigger to start tool and allow tool to
run through a full cycle with drills in fully extended position.
When trigger is released, drills return to original position and
collet extends to open position.
To adjust depth of countersink, turn the spindle adjusting
knobs at the rear of the tool to the appropriate depth. Turning
the knobs counterclockwise reduces depth; clockwise increases depth.
Testing the tool on a separate piece of material will insure that
the tool is operating properly and that the countersink depth
has been accurately set.
Use a conventional drill to drill the pilot hole in the material. The
size of this pilot hole should match the diameter of the collet
and mandrel selected for the tool.
Insert the collet in the pilot hole while holding the pressure foot
firmly against the surface to be drilled, and actuate the trigger.
The collet will retract and clamp the tool firmly against the work
while the two drills will begin feeding into the material. The
drilling cycle is complete when the drills have reached the
maximum pre-set depth. Releasing the trigger will cause the
drills to retract and the collet to release.
The tool is now ready to begin another cycle.
Tool Operation
Optimum performance of the Q-Matic nut plate drill motor
requires a supply of clean, 90 psi air at 35 cfm. Using an in-line
lubricator will provide the proper lubrication for the air motor
and will significantly increase tool life expectancy.
Because O-rings are extensively used to seal systems within
the tool, the elimination of foreign particles and other contaminants will reduce the possibility of damage to these parts.
Always inspect O-rings for damage or wear, and replace as
required. The use of silicone O-ring lubricant is strongly
recommended during reasembly. The addition of oil in the air
line will also increase motor and valve life as well as the life of
the O-rings.

SYMPTOM
REASON
SOLUTION
Air motor and/or clamp and feed functions do not start when trigger is depressed.
Trigger or pilot valves clogged with foreign matter.
Disconnect air line then remove trigger
and pilot valves and inspect for debris.
Inspect "O"-rings and replace if necessary.
Air motor does not run when trigger is
depressed, but feed and clamp functions work properly.
Gears damaged or jammed with debris.
With air line disconnected from tool,
remove backhead, clean and inspect
hears for damage and check both
spindles for free rotation.
Foreign matter in motor inlet.
Remove motor and clean debris from
the motor inlet ports.
Motor throttle valve adjusted too far,
stopping air flow to motor.
Adjust valve until end of valve stem is
flush with the end of housing.
Broken rotor blades, rotor or gear bearings.
Remove motor and inspect rotor blades
and bearings. Replace if necessary.
Pilot valve sticky (not fully closed), or bad
"O"-rings on valve sleeve.
Remove and inspect valve for debris
and for free movement of valve spool.
Inspect "O"-rings, lubricate and reassemble.
Leaking "O"-ring on air motor rear bearing support.
Remove and inspect "O"-rings. Replace
if necessary and reassemble.
Feed control needle valve "closed".
Turn feed control needle valve counterclockwise until feed commences.
Debris in hydraulic system.
Remove feed control valve needle and
bleed hydraulic system until fluid is clear.
Air in hydraulic system.
If air in hydraulic system continues to be
a problem, remove the hydraulic reservoir piston and check or replace its "O"rings. Also check or replace the inner
and outer "O"-rings on the pressure head
located in the main cylinder.
Damaged or worn "O"-ring on collet piston.
Check or replace "O"-ring.
Air motor "idles" when trigger is released.
Motor runs and the tool clamps workpiece
but does not feed.
Tool lunges during feed or when drills
exit the far side of the workpiece or
variation in feed rate.
