Safety warnings

General air tool warnings

1. Read and understand this entire manual before at t em pt i ng assembly or operation.

2. Read and und erstan d all warnin gs posted on the tool an d in th is manu al . Failur e t o comp ly with all of thes e warnings may caus e serious injury.

3. Replace warning labels if they become obscur ed or r em o ved .

4. Do not use this tool for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

5. Alw ays wear appr oved saf ety glass es or f ace shield while using this tool. (Everyday eyeglasses only have impact resistant lenses; they are not safet y glas ses.)

6. Wear ear protectors (plugs or muffs) if the noise exceeds safe levels.

7. Wear gloves and protective clothing if operati on produc es sp arks or fl ying part icles. Gloves s hould be t ight-fitti ng, withou t frayed fingers or hangi ng threads . Keep h ands and body away from the work in g ar ea of to ol.

8. Some dust created by power sanding, sawing, grinding, drilling and other construction activit ies c ont ai ns ch em ic als known t o c aus e cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and other mas onry produc ts .

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you d o this type of work. To reduce your exp osure to th ese chemic als, wor k in a well-ventilated ar ea and work with approved safety equipme nt, su ch as face or dust masks that are specifically designed to filter out microscopic particles.

9. D o not operat e an air tool continu ally at full throttl e wit h ou t a w ork l oad on the tool.

10. The air tool must be properly lubricated before operatin g.

11. Never start a percussion type air tool (chipper, breaker, buster, etc.) without securing the tooling in the retainer and placing the tip against the work surface.

12. Do not operate air tool without its guards in place. Do not modify the tool.

13. Do not oper ate this tool w hile tired or un der the influence of drugs, alcohol, or any medication.

14. Adopt a comfortable posture with proper balance, and maintain secure footing at all times. Non-slip footwear or anti-skid floor strips are recommended.

15. Do not wear loose clothing or jewelry. Confine long hair.

16. Excessive air pressure and too much free rotati on m ay dec r ease life of the tool and may cause a haz ar d ous sit uation.

17. Check air hoses for wear, and keep them away fr om heat and s harp edg es. Rep air or replace damaged air hose immediately. Do not carry tool by the air hose.

18. Air hose may c ause tripping hazards; keep hose away from traffic areas.

19. Do not us e this tool near flamm able objects , or in pot entially exp losive envir onments. Do not use near live electrical wires.

28. Repetitive motions and/or exposure to constant vibration can be harmful to hands and arms. Take frequent breaks and relax hands during extended operation. Change postur e t o avoi d dis comfort or f ati g u e.

29. Compressed air can be harmful if directed toward s ensitive areas of the body, and may propel small particles caught in the air stream. Exercise proper c auti on.

30. Use only recommended accessories; improp er accessori es m ay b e haz ar d ous .

31. Maint ain tools with c are. Keep air tool clean and oiled for best and safest performance.

32. Do not use combustible gases, carbon dioxid e, oxygen or any bottl ed gas as an air sourc e for the t ool. Thes e can pr es ent risk of explosion and serious injury.

33. Do not lubricate the tool with combustible liquids, such as kerosene, diesel or jet fuel.

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.
