VIAIR 450H - Manual (Page 4)

OPERATING INSTRUCTIONS
1. IMPORTANT: Always operate the compressor at or below the MAXIMUM PRESSURE RATING of
the compressor. Please refer to Application & Specifications Sections of this manual for details.
2. Always observe the MAXIMUM DUTY CYCLE of the air compressor. Refer to Compressor
Applications and Specifications Sections of this manual for details. Operation exceeding
maximum pressure ratings and/or duty cycle will result in damage to the air compressor.
3. Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR.
This feature is designed to protect the air compressor from overheating and causing permanent
damage to your air compressor. The thermal overload protector will automatically cut power to
your air compressor should the internal operating temperature of the air compressor rise above
safe levels during excessive use.
4. Should at any time during use, your air compressor automatically shuts off; do not attempt
to restart the air compressor. Turn power switch to the air compressor to the OFF position.
The automatic thermal overload protector will automatically reset when internal temperature of the
air compressor drops below safe levels. Allow air compressor to cool off for about 30 minutes,
before resuming use of the air compressor.
5. Keep the vehicle engine running while using the air compressor to prevent discharge of
your vehicle’s battery.
6. ONLY OPERATE THE AIR COMPRESSOR IN WELL-VENTILATED AREAS.
7. Compressor performance is also enhanced when operating compressor with vehicle’s
engine running.
TIRE INFLATION
This air compressor comes with 1.5 feet heavy duty heat-resistant leader hose with 1/4” industrial
series quick connect stud. By attaching an air hose with 1/4” industrial series quick coupler to the
leader hose, your air compressor is ready to inflate tires. Read and follow tire inflation instructions
carefully to avoid personal injury and damage to air compressor or vehicle.
1. Use heat-resistant, minimum 200PSI-rated working pressure extension hose. Do not use
aftermarket hoses with less than 200PSI working pressure. Some aftermarket hoses may not be
suitable for use with this air compressor due to heat and pressure typically generated by this type
of air compressors.
2. Use of our convenient 25ft. extension coil hose with in-line deflator and Built-in Pressure Gauge
is recommended (Part No. 00025, 5-in-1 Inline Inflator/Deflator).
3. Use of a close-ended tire chuck will cause excessive pressure buildup if tire chuck is not attached
to tire valve stem while air compressor is in operation. Always use an Open-Ended tire chuck
such as the tire chuck equipped on the Inflator/Deflator Coil Hose (P/N 00025) for tire inflation.
4. Always inflate tires to manufacturer’s recommended tire pressures. Exercise extreme caution
when driving with aired down tires. Re-inflate tires before high speed road way travel.
MAINTENANCE & REPAIRS
1. Periodically check all electrical and fitting connections. Clean and tighten or repair as needed.
2. Periodically check all mounting bolts. Tighten as needed.
3. Replace air filter element periodically. Replacement frequency depends on operating frequency
and operating environment. For frequent use in dusty environment, we recommend that you
replace air filter element at least once a month.
4. Regularly clean dust and dirt from compressor cooling fins and motor housing.
5. Your air compressor is equipped with a permanently lubricated, maintenance-free motor.
Never try to lubricate compressor.
6. All repairs should be performed by Manufacturer or Manufacturer’s Authorized
Service Agencies only.
CAUTION: Never touch the air compressor or fittings connected to the air compressor, with bare
hands during or immediately after usage. The leader hose and fittings connected to the leader
hose will become very HOT during and after use. If necessary, wear heat resistant gloves to handle
fittings, air line, and leader hose.
