7. Release throttle lever to stop die grinder.
Maintenance
Lubrication
The die grinder should be lubricated daily (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.
2. P l 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 mach ine oil may b e us ed
as a substitute. Do not use detergent oil.

turnin g wr ench on coll et nu t.
2. Fully insert 1/4-inch shank of grinding
attachment (not included) into collet, and
retigh t en collet nut s ecur el y wi th wr enc hes.
3. Remove protecti v e cap from air i nl et (Figur e
1). If an in-line oil er is not bei ng used, add 4
or 5 dr ops of air t ool oil ( not i nclud ed) i n to
the air inl et.
4. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90psi.
3. Re-connect air. Run die grinder at low
throttle without load for a few seconds to
distri bu te the oil thr oug hout tool.
4. When finished operating die grinder,
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 t o distribut e th e oil. Dis connect air .
The die grinder h as b een pre-gr eased fr om the
manuf actur er, and it is gener ally u nneces sary t o
grease the tool during its normal lif e. However,
should th e tool req uir e fut ur e s ervici ng, a gr eas e
fitting is supplied on the head. Use Lithium
Compl e x M oly 2 greas e or equi valent.
Periodically apply 1 or 2 drops of air tool oil to
throttle lever and safety lever pivots, and work
lever to distribute th e oil.
JET 7
Storage
Rule of Th um b
Avoid storing the die grinder 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.
2. Make sure air compressor supplies clean,
dry air at correct CFM for the tool.
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.
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 th e air lin e may enter the tool an d
cause damage.
5. C h ang e f ilt ers on t h 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 .
General Air Tool
Information
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- 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 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.
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
excessive air pressure or air volume.
• Improper or no lubrication.
8 JAT-405,406 Angled Die Grinders
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 resis tant for f ront c ase c ompon ents on air
impact w renches, gr in d ers and sander s .
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.
