Operation
The belt sander must be
properly lubricated before operation. See
“Lubricati on” se ctio n.
Disconnect sander from air
hose before making any repair or adjustment.
2. Remove protective cap from air inlet. If an inline oiler is n ot b ei ng used, add 4 or 5 dr ops
of air tool oi l ( n ot inc lu ded) into th e air inl et.
3. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT: Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the

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.

Maintenance
Lubrication
The san d er sh ould b e lubr ic ated daily (or before
each use) with air tool oil through the air inlet.
During continual operation, it should be re-oiled
every 1 to 2 hours. This can be done with an inline oiler , or manuall y. If done manu ally, pr oceed
as follows:
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.
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 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.

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.
3. Re-connect air. Run tool at low throttle
withou t load for a f ew secon ds to distr ibute
the oil th roughout tool.
10 JAT-750/ 75 1/ 752 Mini B elt S an d ers
• 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.
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 Fig ur e 1 0) . Place oiler as close
to air tool as pos s ib l e 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.
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.
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.
