Maintenance

Lubrication

The ratchet wrench should be lubricated daily (or before eac h use) with air tool oil throu gh the air inlet. D uring c ontinu al oper ation , it s hould b e reoiled every 1 to 2 hours. This can be done with an in-line oiler, or manually. If done manually, proceed as f ollows:

1. Dis c onnect air hos e from tool.

2. Pl ac e 4 or 5 dr ops of air tool oil into air inlet. NOTE: Air tool oil not provided; it is available

at most major hardware and tool stores. SAE #10 oil or s ewing m achin e oil m ay be used as a substitute. Do not use detergent oil.

3. R e-conn ect air. Run ratc het wrench at low throttle without load for a few seconds to distribu te the oil throug hout tool.

4. When finished operating ratchet wrench, disconnect air hose. Wipe off housing with a dry cloth. Place 4 or 5 drops of air tool oil into air inlet; re-connect air and run tool for a few seconds to distribut e the oil. Disc onn ect air .

The ratch et wrench has been pre-gr eased from the manufacturer, an d it is g en er al l y unn ec es sary to grease the tool during its normal life. However, should the t ool r eq uire f ut ure s er vici ng, a greas e fitting is supplied beneath the housing. Use Lithium C om pl ex M ol y 2 grease or equi valent.

Storage

Avoid storing the ratchet wrench in very humid locations which promotes rusting of internal mechan isms. Al ways oil t he tool and disconn ect air hose before storage.

Air system requiremen t s

1. Use proper air hose size (refer to tool specifications). The hose should be just long enough to serve the working area. Excessive hose len gth wil l c ause pressure drop.

2. Make sure air compressor supplies clean, dry air at correct CFM for the tool.

3. Set air pressure to 90 psi.

and/or unclean air will shorte n the tool’s

life and may create a hazardous situation.

4. Drain water fr om air c ompr essor tank d aily, as well as any c ondensati on from air lines. W ater in the air li ne may enter the t ool and cause damage.

5. Ch ange filters on the air syst em on a reg ul ar basis.

6. Air-line pressure may be increased accordi n gly to c omp ensate f or extra-long air hoses (usually over 25 feet). Inside diameter of hose sh oul d b e minimum 3/8- inc h .

General Air Tool Information

If the air tool is not performing according to specif ications , the f oll owing ar e am ong th e most common causes. (See also “Troubleshooting” section.)

• Contam inat ed air such as a dirty air s ystem or water in the system.

• Using wrong size tool for the job.

• Poor maint enanc e prac tices, such as us ing

excessive air press ure or air volu m e.

• Improper or no lubrication.

Rule of Thum b

If it takes more than 8 seconds to tighten or loosen a bolt or nut with an air impact wrench at maxim um settin g, the air wrenc h is too s mall or the air compressor CFM is not powerful enough for the job. Con tinued use in eit her capacit y will cause damage to the tool.

Tool Pressure

JET Air Tools oper ate on 70- to-100 ps i (pounds per square inch) air pressure measured at the tool when the tool is operating. Set tool to 90 psi unless indicated otherwise. Pressure in excess of 100 psi will shorten the life of the tool.

Air System Recommendat io ns

Equip the air compressor intake with a replaceable air filter that can be easily cleaned.

Use safety shut-off valves so air flow can be stopped quickly in case of a line break.

When us ing m ultipl e hoses , air hoses s hould be larger than leader hose. Join multiple hoses directly, rather than with quick connect fittings which may c ause press ure dr ops and tool pow er reduction.

Use anti-whip devices acr oss hose couplings to prevent hose from whipping in the event of a hose failure or c oup li ng dis connect.

Always us e m oistur e tr aps at t he c om press or for the mai n dis t r ib ut ion line. Use moistur e t r aps and in-line oi lers on eac h downli ne that is to be used for air tools. (See Figure 2). Place oiler as close to air tool as possible for best lubric ati on.

Lubrication

Use a light oi l contai ning rust inhi bitors, such as SAE #10. Many JET air tools have integral oil reservoirs, which should be kept filled when in-line oilers ar e not us ed.

If greasing is required, use a grease that is highly water r esist ant f or fr ont c ase c ompon ents on air impact wrenches, gr in d ers and sanders .

Recycling

Protect the environment. Your tool contains materials which can be recovered or recycled. When its us eful life has expir ed, pl ease leave tool at a specialized facility.
