ROUTINE
LUBRICATION
REQUIREMENTS
M32
5
Lack of or an excessive amount of lubrication will affect the perfor-
mance and life of this tool. Use only recommended
lubricants at
below time intervals:
EVERY 8 HOURS OF TOOL OPERATION
- Fill lubricator reser-
voir of recommended
F.R.L. with spindle oil (29665). If an in line or
air line lubricator is not used, apply several drops of spindle oil
(29665) in air inlet.
EVERY 160 HOURS OF TOOL OPERATION
- Lubricate clutch
parts with molybdenum
grease (40036-1).
Lubricate
gearing.
Pack bearings, coat shafts and lubricate gears with NLGI #1 "EP"
grease (33153). Gearing should contain approximately
1/32 oz.
(.9 g) of grease for single reduction and 3/32 oz. (2.7 g) of grease
for double
reduction.
Right-angle
assembly
should
contain
approximately
1/8 oz. (3.5 g) of grease. Clutch should contain
approximately
l/l 6 oz. (1.8 g) of grease.
AIR SUPPLY REQUIREMENTS
For maximum operating efficiency, the following air supply specifi-
cations should be maintained
to this air tool:
l
AIR PRESSURE
- 90 p.s.i.g. (6.2 bar)
l
AIR FILTRATION - 50 micron
l
LUBRICATED
AIR SUPPLY
l
HOSE SIZE - 5/16" (8 mm) I.D.
An AR0® model C28231-810
air line FILTER/REGULATOR/LU-
BRICATOR
(F.R.L.) is recommended
to maintain the above air
supply specifications.
RECOMMENDED
LUBRICANTS
After disassembly
is complete, all parts, except sealed or shielded
bearings, should be washed with solvent. To relubricate parts, or
for routine lubrication, use the following recommended
lubricants:

INSPECTION, MAINTENANCE AND INSTALLATION
Disconnect air supply from the tool or shut off air supply and ex-
haust (drain) line of compressed
air before performing
mainte-
nance or service to the tool.
It is important that the tools be serviced and inspected at regular
intervals for maintaining
safe, trouble-free
operation of the tool.
Be sure the tool is receiving adequate lubrication, as failure to Iu-
bricate can create hazardous operating conditions resulting from
excessive
wear.
Be sure that the air supply lines and connectors are of proper size
to provide a sufficient quantity of air to the tool.
Tool maintenance
and repair shall be performed
by authorized,
trained, competent personnel. Tools, hose and fittings shall be re-
placed if unsuitable for safe operation and responsibility
should
be assigned to be sure that all tools requiring guards or other safe-
ty devices shall be kept in legible condition. Maintenance
and re-
pair records should be maintained
on all tools. Frequency
of
repair and the nature of the repairs can reveal unsafe application.
Scheduled
maintenance
by competent
authorized
personnel
should detect any mistreatment
or abuse of the tool and worn
parts. Corrective action should be taken before returning the tool
for use.
Disassembly
should be done on a clean work bench with a clean
cloth spread to prevent the loss of small parts. After disassembly
is completed, all parts should be thoroughly washed in a clean sol-
vent, blown dry with air and inspected for wear levels, abuse and
contamination.
Double sealed or shielded bearings should never
be placed in solvent unless a good method of m-lubricating
the
bearing is available.
Open bearings may be washed but should
not be allowed to spin while being blown dry.
Upon reassembling,
lubricate parts where required. Use 33153
grease, or equivalent,
in bearings.
Use 36460 lubricant for "0"
ring assembly. When assembling
"0" rings or parts adjacent "0"
rings, care must be exercised
to prevent damage to the rubber
sealing surfaces. A small amount of grease will usually hold steel
balls and other small parts in place while assembling.
When replacement
parts are necessary, consult drawing contain-
ing the pan for identification.
Always use clean, dry air. Dust, corrosive fumes and for excessive
moisture can damage the motor of an air tool. An air line filter can
greatly increase the life of an air tool. The filter removes rust,
scale, moisture and other debris from the air lines. Low air pres-
sure (less than 90 p.s.i.g.) reduces the speed of the air tool. High
air pressure (more than 90 p.s.i.g.) raises performance
beyond
the rated capacity of the tool and could cause injury. Shown below
is a typical piping arrangement.
