Operation
Follow Operation Safety Rules
Before starting the compressor, review the safety rules
found below and throughout the manual.
WARNING
Failure to follow safety rules may result in serious injury
or death to the operator or bystanders.
Instruct Operators. Owner must instruct all operators in
safe set-up and operation. Do not allow anyone to
operate the compressor who has not read the
Owner’s Manual.
Safety Guarding. Only operate with safety covers,
guards and barriers secured and in good working
order.
Moving Parts. Keep hands, feet, hair and apparel away
from moving parts. Never remove any guards while
the unit is operating. Do not reach into an air vent or
cavity, as they may cover dangerous moving parts.
Ear Protection. Hearing can be damaged from
prolonged, close-range exposure to the noise level
produced by this compressor. Ear plugs or other
hearing protection is recommended for persons
working who are exposed within 15-20 feet of the
running compressor for an extended period of time.
Eye Protection. Wear ANSI/OSHA required “Z87.1”
safety glasses when operating or servicing the
compressor.Pressurized air spray from this unit can
cause severe injury to the eyes. Also, small objects
will become airborne as the air spray contacts them.
Respirator. Wear a respirator when using the
compressed air for spraying. Spray in a well-
ventilated area to prevent health and fire hazards.
Prepare for Operation
Make sure that any regular maintenance has been
performed as prescribed in “Maintenance & Repair”
section.
Drain receiver tank of any moisture.
Check for any unusual noise/vibration.
Ensure the area around compressor is free from
rags, tools, debris and flammable or explosive
materials.
Ensure covers are securely in place.
WARNING: Entanglement hazard
Do NOT operate with protective covers or guards
removed. Beneath these covers are high speed moving
components, which can entangle the operator or
bystanders. Entanglement in this equipment may result
in serious injury, amputation or death.
Start-Up Procedures
CAUTION: Break-in period
Before initial use, run the compressor without air tools
attached and through open air line for 30 minutes to
break-in pump parts.
1. Verify that the tank drain valve is closed.
2. Before turning the power on, connect the RED
clamp to the positive (+) terminal and the
BLACK clamp to the negative (-) terminal on the
12-Volt DC battery.
3. Verify that the pressure switch is in the OFF
position (Figure 13).
Figure 13
4. Turn the regulator clockwise.
5. Verify that the pressure gauge reads zero.
6. Turn the pressure switch to the ON position and
allow compressor to run for minimum of 20
minutes (for the break-in period only).
7. Adjust regulator to desired pressure.
8. Allow pressure in receiver tank to build.
9. Ensure that the compressor shuts down at pre-
set maximum pressure (see note).
Note: This compressor is equipped with a pressure
switch that automatically turns the motor off when the
tank pressure reaches its preset level. Once air
pressure in the tank drops to a preset low level, the
pressure switch automatically turns the motor back on.
