REGULATIONS!
WARNING FAILURE TO COMPLY WITH ALL SAFETY
REGULATIONS MAY RESULT IN SERIOUS INJURY.
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.”
Safe Work Practices Symbol
WARNING The signal word “Warning” identifies all notes on safe
work practices in this operating instruction, alerting to hazards for life
and health of people. Observe these notes and proceed with special
care in the cases described. Pass all safety instructions on to other
operators. In addition to the safety instructions in this operating
instruction, the general local safety and accident prevention rules must
be observed.
Important Notes
CAUTION The signal word “caution!” identifies all portions of this
operating instruction meriting special attention to ensure that
guidelines, rules, hints and the correct work procedures are observed;
and, to prevent damage to and destruction of the machine and/or parts.
1The number in a square is a “service note” reference indicating
additional information for the correct assembly or disassembly of this
product. See Service Note page at end of this manual.
(•) Indicates recommended spare part (or set) for every five (5)
tools. Small, low cost or easily lost parts should be stocked as 3-4
per 10 tools.
WARNING Disconnect the air supply hose before servicing the tool.
INSTALLATION & OPERATION
All 15LN2.. & 15LS2.. models covered by this
parts list...
These models are lever operated horizontal--type motors
with angle heads. The operator actuates and releases the
lever which starts and stops the air motor, gearing and
output spindle.
For best tool performance, a working air pressure of 90
pounds per square inch is recommended. Pipings, fit-
tings and hose should be adequate to maintain 90 psig
while the tool is in operation. An air line filter and lubri-
cator, such as Cooper Power Tool’s #F02--M Filter (1/4”
NPT) and #L02--EP Lubricator (1/4” NPT) should be used
(refer to Cooper’s “F--R--L” brochure). Hose should be
blown out before attaching to the tool.
LUBRICATION
Motor
Lubricate the motor with an air line lubricator, using a
light air tool oil. Adjust the lubricator to dispense one drop
per cycle or three drops per minute. This oil is available in
one (1) quart (540397) or one (1) gallon (533485) quanti-
ties. A high film strength oil (536333) is also available;
this oil cannot be used in Atomist type lubricators, use
only with Economist or serv-oil type lubricators.
Planetary Gearing
Thoroughly grease all gears with Cooper Power Tools
teflon grease every 100,000 cycles. Whenever the tool is
disassembled, pack the gearing with approximately 1/4
ounce of grease. Teflon grease is available in one (1)
pound cans (513156) or two (2) oz. tube (540395).
Establish a routine inspection 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. Too
much grease will cause overheating.
CAUTION Do not use substitutes for oil and
grease. This could result in damage to the tool.
Angle Head Gear Lubrication
When angle head gearing is replaced, wipe on a thin coat
of Molykote, grade G; only a small amount is necessary.
An 8 ounce tube is available under part number 540394.
Molykote has been shown to improve the wearing
characteristics of angle gearing.
