ROUTINE

LUBRICATION

REQUIREMENTS

M20

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 40 HOURS OF TOOL OPERATION

- Flush tool with a

solution of three (3) parts cleaning solvent to one (1) part spindle

oil. After flushing, apply a small amount of spindle oil in air inlet and

run tool for one minute to insure proper lubrication. Built-in oiler

reservoir (pistol grip models) should be filled with spindle oil

(29665).

EVERY 180 HOURS OF TOOL OPERATION

- Lubricate gear-

ing. Pack bearings, coat shafts and lubricate gears with NLGI #1

"EP" grease (33153). Gearing should contain approximately 114

oz. (7 g) of grease per reduction.

AIR SUPPLY REQUIREMENTS

For maximum operating efficiency, the following air supply specifi-

cations should be maintained to this air tool:

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 ARO@ 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

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 "O"

ring assembly. When assembling "O" rings or parts adjacent "O"

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 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.
