WARNING: Do not operate this unit until you read this instruction
manual for safety, operation and maintenance instructions.
Break-in Procedure
NOTICE: Risk of property damage. Serious damage may result if
the following break-in instructions are not closely followed.
This procedure is required before the air compressor is put into
service and when the check valve or a complete compressor pump
has been replaced.
1. Make sure the Auto/Off switch is in the "OFF (O)" position.
2. Check oil level in pump. See Oil paragraph in the Maintenance
section for instructions.
3. Recheck all wiring. Make sure wires are secure at all terminals
connections. Make sure all contacts move freely and are not
obstructed.
4. Open the drain valve (clockwise) fully to permit air to escape
and prevent air pressure build up in the air tank during the
break-in period.
5. Move the Auto/Off switch to "AUTO (-)" position. The
compressor will start.
6. Run the compressor for 30 minutes. Make sure the drain valve
and all air lines are open so there is only a minimal air pressure
build-up in tank. NOTE: After about 30 minutes, If the unit does
not operate properly, SHUT DOWN IMMEDIATELY, and contact
Product Service.
7. Check all air line fittings and connections/piping for air leaks
by applying a soap solution. Correct if necessary. NOTE: Minor
leaks can cause the air compressor to overwork, resulting in
premature breakdown or inadequate performance.
8. Check for excessive vibration. Re-adjust or shim air compressor
feet, if necessary.
9. After 30 minutes, turn the Auto/Off switch to the "OFF (O)"
position.
10. Close the drain valve.
11. Turn the Auto/Off switch to the "AUTO (-)" position. The air
receiver will fill to "cut-out" pressure and the motor will stop.
The compressor is now ready for use.
Before Each Start-Up (Fig. 2)
1. Every day check the sight glass to ensure that the level of oil in
the pump is at the required level.
2. Place Auto/Off switch to "OFF (O)".
3. Close the drain valve.
4. Visually inspect air lines and fittings for leaks.
5. Check safety valve. See To Check Safety Valve under
Maintenance.
6. Attach hose and accessories.
WARNING: Risk of unsafe operation. Firmly grasp air hose in
hand when installing or disconnecting to prevent hose whip.
WARNING: Risk of unsafe operation. Do not use damaged or
worn accessories.
