General Safety Information
I
S
Because an air compressor is a piece
H
of machinery with moving and .
rotating parts, the same precautions
should be observed as with any piece
of machinery of this type when
carelessness in operation or
maintenance is hazardous to
personnel. In addition to the many
obvious safety rules that should be
followed with this type of machinery,
the additional safety precautions as
listed below must be observed:
1.
Read all instructions completely
before operating air compressor
or unit.
2.
For installation, follow all local
electrical and safety codes, as well
as the United States National
Electrical Code (NEC) and the
Occupational Safety and Health
Act (OSHA).
3.
Electric motors must be securely
and adequately grounded. This
can be accomplished by wiring
with a grounded, metal-clad
raceway system, to starter; by
using a separate ground wire
connected to the bare metal of
the motor frame; or other
suitable means.
4.
Protect the power cable from
coming in contact with sharp
objects. Do not kink power cable
and never allow the cable to
come in contact with oil, grease,
hot surfaces, or chemicals.
5.
Make certain that the power
source conforms to the
requirements of your equipment.

6.
Pull main disconnect switch and
disconnect any separate control
lines, if used, before attempting
to work or perform maintenance
on the air compressor or unit.
Tagout or lockout power source.
7.
Do not attempt to remove any
compressor parts without first
relieving the entire system of
pressure.
8.
Do not attempt to service any
part while machine is in an
operational mode.
9.
Do not operate the compressor
at pressures in excess of its rating.
10. Do not operate the compressor
at speeds in excess of its rating.
11. Periodically check all safety
devices for proper operation. Do
not change pressure setting or
restrict operation in any way.
12. Be sure no tools, rags, or loose
parts are left on the compressor
or drive parts.
13. Do not use flammable solvents
for cleaning the air inlet filter or
element and other parts.
14. Exercise cleanliness during
maintenance and when making
repairs. Keep dirt away from parts
by covering parts and exposed
openings with clean cloth or
Kraft paper.
15. Do not operate the compressor
without guards, shields and
screens in place.

16. Do not install a shut-off valve in
the discharge line, unless a
pressure relief valve, of proper
design and size, is installed in the
line between the compressor unit
and shut-off valve.
17. Do not operate compressor in
areas where there is a possibility
of ingesting flammable or toxic
fumes.
18. Be careful when touching the
exterior of a recently run motor
it may be hot enough to be
painful or cause injury. With
modern motors this condition is
normal if operated at rated load
modern motors are built to
operate at higher temperatures.
19. Inspect unit daily to observe and
correct any unsafe operating
conditions found.
20. Do not "play around" with
compressed air nor direct air
stream at body because this can
cause injuries.
21. Compressed air from this
machine absolutely must not be
used for food processing or
breathing air without adequate
downstream filters, purifiers and
controls.
22. Always use an air pressure
regulating device at the point of
use, and do not use air pressure
greater than marked pressure
maximum of attachment.
23. Check hoses for weak or worn
condition before each use and
make certain that all connections
are secure.
