Maintenance
Lubrication
The imp act wrenc h s houl d be lu bric at ed dail y ( or
before each use) with air tool oil through the air
inlet. Durin g conti nual op erati on, 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,
proc eed as f oll ows :
1. D is c onn ec t air h os e f r om tool.
4. Drain water f rom air com press or tan k dail y,
as well as any condens ation from air lin es .
W ater in the air lin e may enter the t ool and
cause damage.
5. C h ang e f ilt ers on th e air syst em on a reg ul ar
basis.
6. Air-line pressure may be increased
accor di n gly to compensate f or extra- l ong air
hoses (usually over 25 feet). Inside diameter
of hos e sh oul d b e mini m um 3/8-inc h .
2. Pl ace 4 or 5 dr ops of air tool oil into air in l et
(Figure 1).
NOTE: Air tool oil not provided; it is available
at most major hardware and tool stores. SAE
#10 oil or s ewing mach ine oil may b e us ed
as a substitute. Do not use detergent oil.
3. Re-connect air. Run impact wrench at low
throttle without load for a few seconds to
distri bu te the oil thr oug hout tool.
4. When finished operating impact wrench,
disconnect air hose. Wipe off housing with a
dry cloth. Place 4 or 5 drops of air tool oil into
air inl et; re-c onn ec t air and r un t h e t ool for a
few s ec onds to distr i but e the oi l. Dis connec t
air.
The i mpact cl utch in th e housing is pre- greased
and should not require further lubrication.
Storage
Avoid storing the impact wrench in very humid
locations which promotes rusting of internal
mechan isms. A lways oil t he tool and disc onnect
air hose before storage.
Air system requi rements
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 gt h wil l c ause pressur e drop.
General Air Tool
Information
If the air tool is not performing according to
specif ications , th e foll owing are am ong t he most
common causes. (See also “Troubleshooting”
section.)
• C ontamin ated air suc h as a dirty air system
or water in the system.
• Using wrong size tool for the job.
• P oor main tenanc e pr actic es, suc h as usin g
excess i ve air press ure or air volume.
• Improper or no lubrication.
Rule of Th um 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 t oo smal l or
the air compressor CFM is not powerful enough
for the job. Continued use in either capacity will
cause damage to the tool.
Tool Pressure
JET Air Tools oper ate on 70-t o-100 psi ( 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.
2. Make sure air compressor supplies clean,
dry air at correct CFM for the impact wrench.
3. Set air pressure to 90 psi.
Excess air pressure
and/or un clean air will sh orten the tool’ s
life and may create a hazardous situation.
8 JAT-101,104,105 Impact Wrenches
Air System Recommendations
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.
W hen using multip le hos es, air hoses shou ld be
larger than leader hose. Join multiple hoses
directly, rather than with quick connect fittings
which m ay caus e pressure dr ops and tool power
reduction.
Use anti-whip devices across hose couplings to
prevent hose from whipping in the event of a hose
failur e or c oup li ng dis connec t.
Always us e m oist ure tr aps at th e c ompr ess or f or
the main distr ib ut ion line. Use mois ture traps an d
in-lin e oilers on eac h down line th at is to be used
for air tools. (See Figure 2). Place oiler as close to
air tool as possible f or best lubric ati on.
Lubrication
Use a lig ht oil contai ning rust in hibitors, such as
SAE #10. Many JET air tools have integral oil
reservoirs, which should be kept filled when in-line
oilers ar e not used.
If greasing is required, use a grease that is highly
water res ist ant f or t he f r ont c ase c omp onen ts on
air imp act wr enc h es , gr in d er s and s an d ers.
Recycling
Protect the environment. Your tool contains
materials which can be recovered or recycled.
W hen its us eful life has expired, please leave tool
at a specialized facility.
