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

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

Maintenance
Lubrication
The imp act wr enc h sh ould b e lubr ic ated d aily ( 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. Plac e 4 or 5 dr ops of air tool oil int o air in let
(Figure 1).
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. Re-connect air. Run impact wrench at low
throttle without load for a few seconds to
distribu te the oil throug 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 inlet; re-conn ec t air and run t h e t ool for a
few sec onds to distri but e the oil. Dis connect
air.
The imp act clutc h in the h ousing is pre-gr eased
and should not require further lubrication.
Storage
Avoid storing the impact 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 impact wrench.
3. Set air pressure to 90 psi.
Excess air pressure
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
8 JAT-206 Impact Wrench
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 esis t ant f or th e fr ont c as e c ompon en ts on
air impact wr enc h es , grin d er s and s an d ers.
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.
