Safety Recommendations
For your safety and the safety of others, read and understand the
safety recommendations and operating instructions before operating a drill.
Always wear protective equipment:
WARNING!
Impact resistant eye protection
must be worn while operating
or working near this tool.
For additional information on eye protection 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 Educational Eye and Face Protection. Z87.1 is available from the American
National Standards Institute, Inc., 11 West 42nd Street, New York,
NY 10036.
CAUTION!
Personal hearing protection is
recommended when operating
or working near this tool.
Hearing protection is recommended 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.
Excessive air pressure above 90 PSIG or worn motor components
can also increase sound level emitted by tool. Proper hearing
conservation measures, including annual audiograms and training
in the use and fit of hearing protection devices may be necessary.
For additional information on hearing protection, refer to Federal
Regulations, Section 1910.95, Occupational Noise Exposure, and
American National Standards Institute, ANSI S12.6, Hearing Protectors.

hazardous fumes and/or dust.
To avoid adverse health effects
utilize adequate ventilation and/
or wear a respirator. Respirators should be selected, fitted,
used and maintained in accordance with Occupational Safety
and Health Administration and
other applicable regulations.
Read the material safety data
sheet of any cutting fluids or
materials involved in the drilling
process.
Follow good machine shop practices. Rotating shafts and moving
components can entangle and entrap, and can 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.
CAUTION
!
properly sized and applied, higher air pressure is unnecessary.
Excessive air pressure increases the loads and stresses on the tool
parts and may result in breakage. Installation of a filter-regulatorlubricator in the air supply line ahead of the tool is recommended.
Before the tool is connected to the air supply, check the throttle for
proper operation (i. e., throttle moves freely and returns to closed
position). Being careful not to endanger adjacent personnel, clear
the air hose of accumulated dust and moisture. Before removing a
tool from service or changing a drill bit, tap, reamer, or any accessory
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.
Sudden and high reaction torque may be experienced with any drill
if:
• Drill motor stalls by excessive load being applied to drill bit or drill
bit snags on material being drilled.
• on break-through when the drill bit passes through the material
being drilled. User must be prepared to resist torque.
• Drill bits are sharp. Handle them carefully to avoid injury.
• Cutting tool maximum speed rating must equal or exceed rated
speed of tool.
• Drill bits or accessories not centered properly in the chuck can
cause excessive wobble or vibration.
• Use appropriately sized chuck key to securely tighten drill bit, tap,
or reamer in drill chuck. Always remove chuck key before starting
tool.
• Use care when drilling because of the possibility of the cutting tool
bending or breaking.
Tools equipped with chuck capacity over 1/4" should have at least
one handle offset at a right angle to drill axis to counteract torque
developed by tool. If tool is equipped with a chuck over 3/8" capacity,
two handles at right angles to the drill axis should be used. One
handle should contain the tool throttle, such as pistol grip or offset
handle models. Always use a dead handle with low RPM — high
torque tools.

lems, exposure to cold and dampness, diet, smoking and work
practices are thought to contribute to the conditions. 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 prolonged symptoms of tingling, numbness, blanching of fingers, clumsiness or weakened
grip, nocturnal pain in the hand, or any other disorder of the
shoulders, arms, wrists, or fingers is advised to consult a physician.
If it is determined that the symptoms are job related or aggravated
by movements and postures dictated by the job design, it may be
necessary for the employer to take steps to prevent further occurrences. These steps might include, but are not limited to, repositioning the workpiece or redesigning the workstation, reassigning workers to other jobs, rotating jobs, changing work 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.
CAUTION
!
The following suggestions will help reduce or moderate the effects
of repetitive work motions and/or extended vibration exposure:
• Use a minimum hand grip force consistent with proper control and
safe operation
• Keep body and hands warm and dry (cold weather is reported to
be a major factor contributing to Raynaud's Syndrome)
The warning 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 warning labels when missing or
when the information can no longer be read. Replacement labels
can be ordered as any spare part.

SAFETY RECOMMENDATIONS ON PAGES 2 thru 4 BEFORE OPERATING A DRILL.
OPERATION
The 111B and 136 Series drills and screwdrivers are designed to operate on 90 psig air pressure. The 111B should
be connected to a 1/4" hose and the 136 to a 5/16" hose.
All drills and screwdrivers are started by pulling the trigger,
and stopped by releasing the trigger.
LUBRICATION
An automatic in-line filter-lubricator is recommended as it
increases tool life and keeps the tool in sustained operation.
SERVICE INSTRUCTIONS
DISASSEMBLY - GENERAL - ALL MODELS
Insert a hex wrench into the drill chuck and tighten the chuck
securely. Use a suitable hammer to strike the hex wrench
sharply in a counterclockwise direction when facing the
chuck. Remove the drill chuck from the spindle. Unscrew
and remove the gear case. The motor unit may now be
removed from the front of the handle. See the following
paragraphs for complete disassembly instructions on the
various subassemblies.
GEAR TRAIN DISASSEMBLY
Unscrew (left hand threads) the spindle bearing retainer
202031. The spindle may now be pressed out of the spindle
bearings.
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 light stain of oil collects on the paper.
Excessive amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for
an extended period of time (overnight, weekend, etc.), it
should receive 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.

REASSEMBLY - GENERAL
All parts should be washed in a solvent and inspected for
damage or wear. Particular attention should be given to all
bearings, gears, gear pins, and rotor blades as failure of
these parts could cause damage to more expensive parts.
Particular attention should be paid to the governor assembly, replacing any of its' parts that show wear or damage. It
is recommended that new rotor blades be installed at each
repair cycle. If not replaced, the used ones must measure a
minimum of 3/16" (4.7mm) at both ends.Failure of these
parts could cause damage to more expensive components.
As the motor unit is assembled, the rear face of the rotor
should be set to within .0015" to the face of the rear bearing
plate. After final assembly, the cylinder should be held firmly,
but not tightly between the two bearing plates and the rotor
should turn freely and not rub either of the bearing plates.
136DL SERIES MOTOR INSTALLATION
When installing the motor unit into the backhead, the rear
bearing plate pin 812167, must engage the 1/8" hole in the
rear motor bore, The front of the backhead is marked to aid
in this operation.
DO HANDLE REASSEMBLY
When installing the throttle link pin, the notched end should
be installed into the backhead in a vertical position to engage
the throttle valve stem.
REASSEMBLY - COMPLETE
The rotor pinion (if required) should be installed on the rotor
shaft with the undercut side toward the rotor.
Install (left hand threads) the spindle bearing retainer on the
front of the gear case. Put a few drops of 10W machine oil
into the tool's air inlet to insure immediate lubrication of all
motor parts when the tool is tested.
Must be replaced if less than
3/16" (4.7mm) on either end.
Inspect and replace any "O" rings or seals that show signs
of wear or deterioration.
All gears, gear pins, and open bearings should receive a
generous amount of No. 2 Moly grease during reassembly.
Reassembly of all of the various sub-assemblies is in the
reverse order of disassembly, however, the following paragraphs list some of the more important reassembly procedures.
