DISASSEMBLY
1. Loosen (3) cap screws. Remove shear head by twisting
and pulling forward.
2. Remove the (3) cap screws completely. Be careful not to
lose rear bushing when removing middle cap screw.
3. Remove center scissor blade from shear housing by
tapping blade gently rearward. Be careful not to lose
bushing from hole in center blade. Side knife and side
spacer will now drop out of housing.
ASSEMBLY
1. Install spacer (part #1546) over planet cage, then
eccentric bearing assembly. Tighten bearing assembly.
Lubricate bearing with a good grade of bearing
grease.
Installing cutter blades:
2. Place the side knife and side spacer in position in the
shear housing. Insert center cap screw with rear spacer
bushing (part #14-1556) between them - start cap screw
into threads just enough to hold blades in position. DO
NOT TIGHTEN.
3. Insert spacer bushing into hole in center scissor blade and
lubricate with a good grade of bearing grease.
4. Install center scissor blade into shear housing by tapping
blade gently forward, using a drift to line up hole in center
blade with forward holes in housing.
5. Insert and tighten forward cap screw, making sure spacer
bushing in center blade stays in position.
6. Apply a good grade of bearing grease to yoke of center
blade where it rides on the eccentric bearing assembly.
7. Insert rear cap screw but do not tighten.

LUBRICATION
Air Motor Lubrication
Use "Air Lube 10H-NR" which has a paraffin base. Air Lube is available from CooperTools in one gallon containers by
ordering part number 533485. In-line oilers should be used, adjusted to yield about one drop per minute (not per cycle) ini-
tially. Oiler adjustments vary (50 clicks/drop, 20 clicks/drop, etc.). If in doubt, contact your supplier. Each time the tool
cycles, a drop or partial drop is released into the tool.
Planetary Gear Lubrication
Use teflon grease, available from CooperTools in one pound cans, under part number 513156. Establish a routine inspec-
tion and re-lubrication program, don't short cut. Re-lubricate planetary by filling 1/3 to 1/2 full. Midget grease fittings are
provided on the gear housings and internal gears for external lubrication.
During periodic maintenance, re-lubrication or service where the gears are not replaced, use Cooper's teflon grease. Fill
1/3 to 1/2 full but do not overfill. Too much grease will cause overheating.
GEARING REASSEMBLY
Planetary Gearing
Place a small amount of grease in each planet gear, as
illustrated at right, and place on a smooth clean surface.
Insert a planet pin - notched end up - in each gear. Then,
install the correct number of rollers (12) around each gear.
Grease will hold the rollers in position when the planet gears
are removed.
MOTOR REASSEMBLY
1. Install ball bearings into both the front and rear plates.
2. Assemble rotor to rear plate/bearing assembly with the
rotor's retaining nut. Position and set the rotor as close as
possible to the rear plate, without dragging or rubbing.
a. A good practice is to stone the blade slots and polish the
ends with a medium grit emery cloth.
b. Assemble components making sure the bearing is firmly
seated in the rear plate.
RECOMMENDED SPARE PARTS LIST
These parts are suggested as a recommended inventory of spare parts. Where parts are small, low cost, or
easily lost, then we recommend stocking 3 - 4 for every 10 tools. Other larger, lower wear, or more expensive
parts should be maintained as one (or one set) for every six to ten tools.

3. Begin tightening rotor nut without over tightening to avoid
damaging the ball bearing. Alternately spin the rotor while
tightening until clearance is judged to be proper - about
0.001" clearance.
a. One method, shown at right, is to use a piece of
pipe which is slightly longer than the rotor, and tap
lightly against a work bench several times. This
helps seat threaded components.
b. A second method is to hold the rotor rear plate
assembly vertically (plate downward) and lightly
strike the edge of the plate with a wood block,
alternating sides.
PARTS INSPECTION
1. Wash all parts except ball bearings in solvent. Dry
and place on a clean cloth for inspection.
2. Check ball bearings for wear. Bearings should turn
smoothly with no appreciable shake or looseness.
3. Check rotor blades for wear by comparing with a new
blade. Replace if worn more than 1/32" in height.
4. Check motor cylinder for grooves, gouges or pitting.
Honing is permissible, however, never remove more than
about 0.001" or 0.002" of material. Replacement is
usually recommended.

ALWAYS COMPLY WITH:
1. General industry Safety & Health Regulations, Part 1910,
OSHA 2206, available from: Sup’t of Documents; Government
Printing Office; Washington, DC 20402.
2. Safety Code of Portable Air Tools, ANSI B186.1 available from:
American National Standards Institute, Inc.; 1430 Broadway;
New York, NY 10018.
3. State and Local regulations.
Portions of the above codes and regulations are listed below for
quick reference.
THE FOLLOWING EXCERPTS ARE NOT INTENDED TO BE ALL
INCLUSIVE: STUDY AND COMPLY WITH ALL REGULATIONS!
1. TOOL INTENT: Tools shall be used only for purposes intended
in their design (refer to product catalog).
2. AIR SUPPLY: Test and operate tools at 90 PSIG maximum
unless tool is marked otherwise. Use recommended airline
filters-regulators-lubricators.
3. UNUSUAL SOUND or VIBRATION: If tool vibrates or produces
an unusual sound, repair immediately for correction.
4. OPERATOR PROTECTIVE EQUIPMENT: Wear goggles or
face shield at all times tool is in operation. Other protective
clothing shall be worn, if necessary. SEE REGULATIONS.
5. SAFETY MAINTENANCE PROGRAM: Employ a safety
program to provide inspection and maintenance of all phases
of tool operation and air supply equipment in accordance with
“Safety Code for Portable Air Tools.”
Safety First!
The SPEED TOLERANCE is rated speed minus 10%. The tool must NOT have a free speed higher than the
RPM stamped on the housing. Use an accurate tachometer to check the tool speed, with 90 psig air pressure at
the tool with the tool running.
CAUTION: Disconnect the air supply hose before servicing the tool.
INSTALLATION:
For best performance, a working air pressure of 90 pounds per
square inch is recommended. Pipings, fittings, and hose should be
adequate to maintain 90 psig while the tool in in operation. An air
line filter and lubricator, such as CooperTools’ #F02-M Filter (1/4”
NPT) and #L02-EP Lubricator (1/4” NPT) should be used (refer to
product catalog). Hose should be blown out before attaching to tool.
LUBRICATION:
The gears in angle head style tools must be lubricated every 8
hours of operation with high quality gear grease. CooperTools’
grease #45-0980 is recommended. A Grease Gun, #45-1982, is
furnished with each geared tool. Insert the nozzle into the flush type
lube fitting, located on the side or top of the angle head, and pump
four or five times. The motor must be lubricated and moisture free.
Use a high grade SAE #5 spindle oil, such as CooperTools’
Lubricating oil #45-0918 (one quart). Two or three drops per minute
should be sufficient lubrication. NOTE: Turbine motor type tools
(10-90 & 10-95) must NOT be oiled.
LOSS OF POWER:
It is seldom necessary to disassemble this tool for loss of power. A
loss of power may not be related to the tool. First, check the air line
regulator. Also, check the air line pressure; it should be 90 psig at or
near the tool while the tool is running. Check the size of hose and
fittings to be certain they are not causing air restrictions. Make
certain they are not plugged with dirt, rust, or scale.
SERVICE INSTRUCTIONS:
The parts of this tool are small and require careful handling. We
recommend the tool be returned to the factory for repair. However, if
the tool is to be repaired in the field, carefully follow instructions. Do
not squeeze the tool or parts in a vise except as specified. Care
must be used during assembly and disassembly. When pressing
bearings onto a shaft, press only on the inner race. When pressing
bearings into a bore, press on the outer race only. NOTE: Ball
bearings are the shielded type. They are lubricated for life by the
bearing manufacturer and should not be washed out with solvents to
clean.
WARNING!
CHECK SPEED OF TOOL WITHOUT WHEEL BEFORE IT IS RELEASED FOR USE.
