Warnings and Hazards
• CO Poisoning: Exhaust from engine contains carbon monoxide, a poisonous gas that can cause
carbon monoxide poisoning and possible death if inhaled. ONLY run air compressor OUTDOORS and
at least 20 feet from the home, away from windows, vents, and air intakes, to allow proper
ventilation. If you start to feel sick, dizzy, or weak while using the air compressor, shut off the engine
and get to fresh air RIGHT AWAY.
• Injection Injury: High-pressure air stream can pierce skin and underlying tissues, leading to serious
injury and possible amputation. Such an injection injury can result in blood poisoning and/or severe
tissue damage.
• Flying Debris: High-pressure air stream can cause flying debris and possible surface damage.
• Electric shock: Operating equipment in wet conditions or near water can cause electric shock.
• Not For Breathing Air: AMP compressors are NOT designed, intended, or approved for supplying
breathing air. No compressed air should be used for breathing unless air is treated in accordance
with applicable standards.
• Fire/Explosion: Sparks from air powered tool heads or attachments can ignite fuel or other
flammable liquids or vapors in the vicinity. Exceeding the maximum pressure for air tools or
attachments could cause them to explode.
• Burns: Compressor pump, engine and discharge tubing are hot surfaces that can cause burn
injuries. Detailed safety information about these hazards appears throughout this manual.
Inspect your air compressor carefully for any damage that may have occurred during transit. Be sure
to inspect and tighten all bolts, screws, and fittings before attempting to start the unit. Do not
attempt to operate a damaged unit. It may burst and cause serious injury or property damaged.
Your compressor comes equipped with a guard over the drive wheel and belt
assembly. Never attempt to operate this unit if the guard is damaged or removed.
Personal injury could result from contact with moving parts.
Never remove or attempt to adjust the safety valve. Keep it free from paint or any
other accumulations.
This unit may cause electrical arcs that could ignite flammable gas or vapor. Keep
flammable items away from the compressor and keep the compressor from
flammable conditions

Compressor Pump requires 30SAE oil. Fill to middle or top
of red dot in sight glass. Do not overfill or this will cause
damage and oil spills.
For all Engine related information please refer to separate
manual provided for Kohler rh265-3124 engine.
MINIMUM DISTANCE FOR CLEARANCE IS 3 FEET FOR ALL
COMBUSTIBLE MATERIAL
FOR OUTDOOR USE ONLY!
NEVER USE THIS UNIT INSIDE OF ANY BUILDING, ENCLOSURE OR A RECREATION VEHICLE (RV). NO
MODIFICATIONS WILL ELIMINATE THE DANGER OF POSSIBLE CARBON MONOXIDE POISONING, FIRE
OR EXPLOSION.

OPERATION INSTRUCTIONS
UNDERSTANDING YOUR AIR COMPRESSOR
•Hose and Regulator Use 3/8-inch hose and regulator that has a minimum rating that
exceeds the maximum working pressure of the compressor. The amount of air pressure
released at the hose outlet is controlled by the regulator.
•ACM Safety Valve This valve will release excessive pressure if the maximum pressure is
exceeded.
•Discharge Tube This tube carries compressed air from the pump to the check valve. Never
touch the discharge tube because it becomes very hot during operation.
•Unloader Valve used to release all pressure from the tanks and pump for starting.
•Check Valve This is a one-way valve that allows air to enter the tank but prevent air from
going out of the tank.
•Handle The handle is provided to move the compressor.
•Belt Guard The belt guard covers the belt and pulley.
•Drain Petcock Each tank has a drain petcock on the bottom and is used to drain moisture
from the tank. Open the petcock and reduce air pressure below 10 psi and allow moisture to
drain. This should only be done daily to reduce the risk of corrosion.
STARTING YOUR UNIT
•1. Move the manual throttle/choke lever into the start position.
•2. Put unloader in open position.
This picture
shows open
position.
This is
closed
position

5
•Gently Pull starter grip slowly until resistance is felt.
• Pull cord briskly
• Return starter cord gently into the recoil housing.
• Move throttle choke lever to desired rpms.
• Close the unloader valve
You may need to pull recoil start multiple times before engine starts.
Please refer to Kohler Engine manual for troubleshooting.
Units are sometimes pre-tested. If unit has trouble starting, open ACM Safety Valves
on each tank. Then follow starting steps above. Close the valves once started.

Maintenance & Troubleshooting

7
• RELEASE ALLPRESSURE FROM THE SYSTEM
BEFORE ATTEMPTING TO PERFORM ANY
MAINTENANCE.
• BEFORE EACH USE. CHECK THEAIR FILTER,
THE OIL LEVEL, AND THE GASOLINE SUPPLY
BEFORE STARTING THE ENGINE. TEST THE
ACM SAFETY VALVE BEFORE STARTING THE
ENGINE.
• PULL THE RING ON THE SAFETY VALVE AND
LET IT SNAP BACK TO ITS NORMAL POSITION.
THIS VALVE IS DESIGNED TO RELEASE AIR
AUTOMATICALLY WHEN THE TANK PRESSURE
EXCEEDS THEPRESET MAXIMUM. THE ACM
VALVE MUST BE REPLACED IF AIR LEAKS AFTER
THE RING HAS BEEN RELEASED OR IF THE
VALVE IS STUCK AND CANNOT BE ACTIVATED
BY THE RING.
• NEVER TAMPER WITH THE ACM SAFETY
VALVE! CLEAN DEBRIS FROM THE ENGINE,
FLYWHEEL, TANK, AIRLINES, AND PUMP
COOLING FINS BEFORE ATTEMPTINGTOSTART
THE ENGINE.
• AFTER EACH USE. BE SURE TO DRAIN THE
TANKS COMPLETELY AFTER EACH USE.
• COMPLETE TANK INSPECTION. CAREFULLY
INSPECT THE TANK OFTEN FOR CRACKS
FORMING AROUND THE WELDS. REMOVE
PRESSURE FROM THE TANK IMMEDIATELY
AND REPLACE THE TANK IF A CRACK IS
DETECTED.
• NEVER EVER ATTEMPT TO REPAIR OR
MODIFY A TANK!
•DRIVE BELT BELTS TEND TO STRETCH AS A
RESULT OF NORMAL USE. THE BELT WILL
DEFLECT ABOUT 1/2 INCH WITH FIVE POUNDS
OF PRESSURE APPLIED MIDWAY BETWEEN THE
ENGINE PULLEY AND THE PUMP.
• ADJUSTING THE BELT TENSION REMOVE THE
BELT GUARD.
• LOOSEN THE ENGINE BRACE.
•LOOSEN THE 4 FASTENERS HOLDING THE
ENGINE TO THE BASEPLATE.
• SHIFT THE MOTOR TO PROPERLY ALIGN BELT.
LAY A STRAIGHT EDGE AGAINST THE FACE OF
THE FLYWHEEL, TOUCHING THE RIM IN TWO
PLACES.
• ADJUST THE MOTOR OR THE FLYWHEEL
UNTIL THE BELT RUNS PARALLEL TO THE
STRAIGHT EDGE.
• USE A GEAR PULLER TOMOVE THE PULLEY ON
THE SHAFTAND TIGHTEN THE FASTENERS.
• ADJUST THE BRACE AND REINSTALL.
• STORAGE. DRAIN TANKS. DISCONNECT HOSE
AND HANG WITH OPEN END DOWN TO ALLOW
MOISTURE TO DRAIN.
• STORE IN A COOL, DRY PLACE.

pump
4.) Low oil in pump
1.) Move compressor to a well ventilated area
2.) Clean all cooling surfaces including air filers on
engine
and pump

pump. If
one or both heads are blowing air out, pump must
be replaced

oil as needed. Use SAE 30 in compressor pump
Excessive Belt Wear
1.) Pulley is out of alignment
2.) Belt too loose or too tight
