• 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).

• 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.

• Cutting tools used with these drill motors are sharp. Handle them

carefully to avoid injury.

Before mounting any positive feed drill, check

the lock screws in the tooling fixture and drill

bushing. Make sure both are in good condi-

tion and securely tightened.

Positive feed drills can exert high torques and high thrust loads.

If failure of the lock screws or drill bushing occurs, the drill may

suddenly spin and back away from the drill fixture.

Always remove chuck key or drill drift before operating tool.

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.

Some non-ferrus metal chips (or dusts) are

combustible. Examples: Aluminum, mag-

nesium, Titanium, and Zirconium. See the

material safety data sheets for combustibility of materials drilled.

Never collect spark generating material with combustible mate-

rial. Examples: Collecting both steel and aluminum or steel and

titanium.

Safety Recommendations

For your safety and the safety of others, read and understand

the safety recommendations and operating instructions be-

fore operating any drill motor.

Always wear protective equipment:

For additional information on eye and face protection, refer to

Federal OSHA Regulations, 29 Code of Federal Regulations,

Section 1910.133., Eye and Face Protection, and American

National Standards Institute, ANSI Z87.1, Occupational and Edu-

cational Eye and Face Protection. Z87.1 is available from the

American National Standards Institute, Inc. 11 West 42nd Street,

New York, NY 10036.

Hearing protectors are required in high noise areas, 85 dBA or

greater. The operation of other tools and equipment in the area,

reflective surfaces, process noises and resonant structures can

substantially contribute to, and increase the noise level in the

area. For additional information on hearing protection, refer to

Federal OSHA Regulations, 29 Code of Federal Regulations,

Section 1910.95, Occupational Noise Exposure, and American

National Standards Institute, ANSI S12.6, Hearing Protectors.

Follow good machine shop prac-

tices. Rotating shafts and mov-

ing components entangle and

entrap, and may result in seri-

ous 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 de-

signed to operate on 90psig (6.2

bar) maximum air pressure us-

ing the proper hose. Excessive

air pressure increases the loads and stresses on tool parts and

drills, and may result in breakage. The installation of a filter-

regulator-lubricator in the air supply line ahead of the tool is highly

recommended.

Do not wear loose fitting clothes,

long hair, gloves, ties or jewelry.

WARNING

CAUTION

CAUTION!

CAUTION

Quackenbush drills

are often used with

lubricant or cooling

systems which must

be properly main-

tained to avoid leak-

age. Failure to do so

can result in serious injuries from slipping on oily surfaces.

Nose pieces usually used with these drills are generally slotted for

visibility and access to chuck and cutter.

The spindle on positive feed drills usually

retracts at a much faster rate than it feeds.

Care should be taken to avoid entrapment.

Keep fingers and hands away

from slots in the tool nose at

all times. Rapid spindle re-

traction occurs automatically

on most models after drilling

cycle and can be activated

manually even with the air

supply disconnected on some

models.

Due to the multitude and variety of tooling applications, the User's

Methods Engineering, Standard Tooling Engineering, and/or Safety

Engineering Departments, etc., must consider any hazards that

may be associated with each specific application of this product

and provide adequate operator protection from inadvertent con-

tact with any moving components.

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 vascu-

latory 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 gradu-

ally 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 con-

trolled through tool selection and work location.

Safety Recommendations

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, clumsi-

ness 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 following recommendations will help reduce or moderate the

effects of repetitive work motions. The operator of any drill should:

• Use a minimum hand grip force consistent with

proper control and safe operation

• Keep body and hands warm and dry

• Avoid anything that inhibits blood circulation

— Smoking Tobacco

— Cold Temperatures

— Certain Drugs

• Avoid awkward postures

• Keep wrists as straight as possible

• Interrupt work, activities, or rotate jobs to provide

periods free from repetitive work motions.

Safety Labels

The safety labels found on these tools are an

essential part of this product. Labels should

not be removed. Labels should be checked

periodically for legibility. Replace safety la-

bels when missing or when the information

can no longer be read. Safety labels should

always be placed on any tool nose before

installing on tool. Replacement labels can

be ordered using number below.

STORAGE

In the event that it becomes necessary to store the tool for an

extended period of time (overnight, weekend, etc.), it should re-

ceive a generous amount of lubrication at that time and again

when returned to service. The tool should be stored in a clean

and dry environment.

OPERATING INSTRUCTIONS

The 15QD & 15QDB-S125 Positive Feed Drill is designed to

operate on 90 psi air pressure using a 5/16'' hose up to 10' in

length. If additional hose is required, a larger hose may be

attached to the 5/16" hose.

Three rotatable collars control the adjustment and operation of the

drill.

Throttle ring A starts and stops the motor and spindle rotation.

Collar B (Rear Stroke Adjustment) locates the starting position of

the spindle relative to the workpiece.

Collar C manually starts forward motion of the spindle (feed), and

manually retracts the spindle.

ADJUSTMENT AND OPERATION

Lock unit into drill fixture. Rotate collar B counterclockwise,

advancing drill tip close to the workpiece.

Start motor by rotating the throttle ring A to the on position. Rotate

collar C counterclockwise maintaining steady pressure on collar

until feed mechanism is engaged, starting drilling operation. The

feed stops at the end of the stroke. The spindle is returned to the

starting position by rotating the feed collar Cclockwise. However,

the operation can be stopped at any time by rotating the feed collar

C clockwise, disengaging positive feed mechanism and retracting

spindle. The rotating of the spindle must be stopped by rotating the

throttle ring A to the off position.

LUBRICATION

An automatic in-line filter-lubricator is recommended as it in-

creases tool life and keeps the tool in sustained operation. The

in-line lubricator should be regularly checked and filled with a

good grade of 10W machine oil. Proper adjustment of the in-line

lubricator is performed by placing a sheet of paper next to the

exhaust ports and holding the throttle open approximately 30

seconds. The lubricator is properly set when a very light stain of

oil collects on the paper. Excessive amounts of oil should be

avoided.

No 864239, which is used in the 1400 RPM gear train, can then

be removed from the first reduction spider.

The gear train on the 2000 RPM and 3000 RPM power units is

disassembled by unscrewing the gear case, No. 611534, from

the motor housing. Unscrew the spindle nut, No. 613073, and

press the spider out the rear of the gear case.

To remove the motor unit from either the straight motor housing

or the pistol grip, hold the rotor shaft in a soft jawed vise and slip

the motor unit out of the motor housing. Using a soft faced mallet,

tap the rotor out of the front rotor bearing, No. 844772. The front

bearing plate, No. 864235, cylinder, No. 864236, and four (4)

rotor blades, No. 864234, may now be removed. Remove the

rotor bearing retainer, No. 812231, and the rotor shims from the

rear of the rotor. Rest the front face of the rear bearing plate, No.

864232, on top of the vise jaws and with a suitable driver, tap the

rotor out of the rear rotor bearing, No. 847095.

To disassemble the straight motor housing, remove the throttle

ring retainer, No. 613059. This will allow the throttle ring, No.

To remove the throttle lever, No. 864650, clamp the motor hous-

ing in the vise and drive out the throttle lever pin, No. 864671.

This will allow the throttle lever to drop into the handle and it may

then be removed through the front of the housing. The muffler,

No. 881646, can be removed at this time for inspection. The trig-

ger, No. 864652, and trigger bushing, No. 864649, may be re-

moved by driving out the trigger stop pin, No. 844653.

REASSEMBLY

The tool is reassembled in the reverse order of disassembly. All

parts should be thoroughly cleaned and inspected for damage or

wear. Damaged or worn parts should be re- placed. Bearings

which feel rough or have excessive end play should be replaced.

Rotor blades should be replaced every repair cycle or if they

measure less than 7/32" (5.6mm) at either end.

When assembling the motor, a clearance of .0015" is desired

between the front face of the rear bearing plate and the rear face

of the rotor. If the rotor rubs the face of the rear bearing plate, it

indicates that the rotor collar is too short and must be replaced. If

clearance is more than .0015", sand the square face of the rotor

collar until the desired clearance is obtained. After the rotor collar

has been fitted, install rotor shims between the retainer ring and

the rear rotor bearing to keep the bearing against the rotor collar.

As the gear train and drill head are assembled, apply a generous

amount of NLGI 2-EP grease to all of the gears, gear case teeth,

gear spiders, and bearings. On the triple reduction gear train, be

sure that the notch in the ring gear, No. 864329, is aligned with

the ring gear pin in the front gear case. As the gear train is as-

sembled to the motor and motor housing, make sure that the

teeth on the rotor mesh properly with those in the gear spider.

During reassembly of the cross shaft, place the worm wheel over

the long end of the cross shaft with the hub covering the hexagon

portion of the shaft. Place the worm wheel spacer over the shaft

with the slot aligned with the pin hole and insert the pin. Apply

grease to the two (2) slots and two (2) holes in the worm wheel

hub. Insert the two (2) pins and two (2) steel balls. Holding the

cross shaft assembly with the worm wheel to the right of the clutch,

press the clutch spring over the hub of the worm wheel engaging

the steel balls with the holes in the clutch spring.

NOTE: The clutch spring must wrap on the hub away from you

with respect to the holes in the spring.

NOTE: Wrapping the spring in the opposite direction will decrease

the holding power of the clutch.

Insert the snap ring, No. 844965, in the gear body with the open

section toward the pinion, No. 619119, for clearance of the pin-

ion. "Lubriplate 907" grease or equivalent should be packed in

and around the lead screw to aid in cushioning the retract cycle.

When installing the half-nuts in the thrust collar, the radius on the

half-nuts is to the left when facing the housing.

After the tool is assembled, place a few drops of 10W oil in the air

inlet bushing before attaching the air hose. This will insure imme-

diate lubrication of all motor parts as soon as the air is applied.

Must be replaced if

7/32" (5.6mm) or less

at either end.
