ROUTINE

LUBRICATION

REQUIREMENTS

Lack of or an excessive amount of lubrication will affect the perfor-

mance and life of this motor. Use only recommended

lubricants at

below time intervals:

EVERY 8 HOURS OF MOTOR OPERATION

- Fill lubricator res-

ervoir 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 MOTOR OPERATION

- Lubricate gear-

ing. Pack bearings, coat shafts and lubricate gears with NLGI #l

"EP" grease (33153). Gearing should contain approximately

1/8

oz. (3.5 g) of grease.

AIR SUPPLY REQUIREMENTS

For maximum operating efficiency, the following air supply specifi-

cations should be maintained to this air motor:

AIR PRESSURE

- 90 p.s.i.g. (6.2 bar)

AIR FILTRATION - 50 micron

LUBRICATED

AIR SUPPLY

HOSE SIZE - 5/16" (8 mm) I.D.

An AR08

model C28231-810 air line FILTEWREGULATOR/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 motor or shut off air supply and ex-

haust (drain) line of compressed

air before performing

mainte-

nance or service to the motor.

It is important that the motors be serviced and inspected at regular

intervals for maintaining safe, trouble-free

operation of the motor.

Be sure the motor is receiving adequate lubrication, as failure to

lubricate

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 motor.

Maintenance

and repair shall be performed

by authorized,

trained, competent personnel. Hose and fittings shall be replaced

if unsuitable for safe operation. Responsibility should be assigned

to ensure that guards or other safety devices are installed and be-

ing used properly on certain motors. Maintenance

and repair re-

cords should be maintained

on all motors. Frequency

of repair

and the nature of the repairs can reveal unsafe application.

Scheduled

maintenance

by competent

authorized

personnel

should detect ant mistreatment

or abuse of the motor and worn

parts. Corrective action should be taken before returning the mo-

tor 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 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 part for identification.

Always use clean, dry air. Dust, corrosive fumes and/or excessive

moisture can damage the motor. An air line filter can greatly in-

crease the life of an air tool. The filter removes rust, scale, mois-

ture and other debris from the air lines. Low air pressure (less than

90 p.s.i.g.) reduces the speed of the air motor. High air pressure

(more than 90 p.s.i.g.) raises performance

beyond the rated ca-

pacity of the motor and could cause injury. Shown below is a typi-

cal piping arrangement.
