Installation & Assembly

The air compressor should be turned off and unplugged fromthe power source before any maintenance is performed aswell as the air bled from the tank and the unit allowed time

to cool. Personal injuries could occur from moving parts,electrical sources, compressed air or hot surfaces. Theregulator assembly must be attached before use. Failure toassemble correctly could result in leaks and possible injury.If unsure of assembly instructions or you experience difficultyin the assembly please call your local service department forfurther instruction.

Quick Connect Assembly1. Before assembly be sure that theQuick Connect (Q.C.) threads have asealant applied from the factory to preventleaks around the threads. If no sealant is

present, wrap the threaded portion withTeflon tape.2. Attach the Q.C. assembly to the air compressor byaligning the Q.C. threads to the regulator on the manifold.Be certain to align the threads before tightening to preventthread damage.3. The assembly should turn clockwise 1 to 1.5 revolutionsafter hand-tightening with a 13/16ths size wrench. To preventdamage and leaks, do notover-tighten.

To Install the Air Intake FilterRemove the air intake filter from the

poly bag and thread it onto the headof the compressor as shown.

Do not attempt to start the air compressor without first addingoil to the crankcase. Serious damage can result unless filledwith oil. The pump is shipped without oil from the factory.Only use non-detergent oils since multi-viscosity motor oilsleave carbon deposits on pump components, thus reducingperformance and compressor life.

Drain the tank to release all tank air _ _.=t_{ '_L

pressure before removing the oil fill cap.Be sure the air vent in the oil fill cap (see

figure to the right) is free from debris.If air vent is blocked, pressure can build

in crankcase causing damage to thecompressor and possible personal injury.

Lubrication and Oil

Remove the oil fill cap by turning it _ /_-,,,counter-clockwise by hand. Fill thecompressor pump with an air compressoroil such as SAE-30 non-detergent (API

CG/CD Heavy Duty) oil at slow intervalsuntil the oil reaches the center of the red

circle in the sight glass ( see figure above).Use SAE-10 during extreme winter conditions.

Location of the Air Compressor

The air compressor should always be located in a clean,dry, and well ventilated environment. The unit should haveat minimum, 12 inches of space on each side. The air filterintake should be free of any debris or obstructions. Checkthe air filter on a daily basis to be sure it is clean and inworking order.

PROBLEM POSSIBLE CORRECTION

Air leaks at the check valve A defective check valve results in a constant air leak at the pressure relief valve

or at the pressure relief valve, when there is pressure in the tank and the compressor is shut off. Drain the tank,

then remove and clean or replace the check valve.

Air leaks between head and Be sure of proper torque on head bolts. If leak remains, contacta servicetechnician.

cylinder.

Air leak from safety valve. Operate the safety valve manually by pulling on the ring. If the valve continues to

leak when in the closed position,it should be replaced.

Pressure reading on the

regulated pressure gauge

drops when an accessory isused.

If there is an excessive amount of pressure drop when the accessory is used,

replace the regulator.

NOTE:

Adjust the regulated pressure under flow conditions(while accessory is being used),

It is normal for the gauge to show minimal pressure loss during initial use of the

tool.

Excessive tank pressure. Move the Auto-On/Off lever to the Off position. If the unit doesn't shut off, unplugit

from the power source and contact a service technician.

Motor will not start. Make sure power cord is plugged in and the switch is on. Inspect for the proper size

fuse in your circuit box. If the fuse was tripped, reset it and restart the unit. If

repeated tripping occurs, replace the check valve or contact a service technician.

Excessive moisture in the

discharge air.

Air leaks from the tank bodyor tank welds.

Remove the water in the tank by draining after each use. High humidity

environments will cause excessive condensation. Utilize water filters on your air

line.

NOTE:

Water condensation is not caused by compressor malfunction. Be sure the

compressor's air output is greater than your tool's air consumption rate.

Never drill into, weld or otherwise modify the air tank or it will weaken. The tank can

rupture or explode. Compressor cannot be repaired. Discontinue use of the air

compressor.
