VIAIR 460C - 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 to the air compressor OFF. The automatic thermal overload
protector will automatically reset when internal temperature of the air compressor drops below
safe level. After allowing air compressor to cool off for about 30 minutes, you can safely resume
use of the air compressor.
5. To prevent discharge of your vehicle’s battery, we recommend that you keep the vehicle’s engine
running while using the air compressor.
6. ONLY OPERATE THE AIR COMPRESSOR IN WELL-VENTILATED AREAS.
7. Compressor performance is enhanced when operating compressor with vehicle’s engine running.
MAINTENANCE & REPAIRS
1. Periodically check all electrical, fittings connections. Clean and tighten as needed.
2. Periodically check all mounting screws. 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 the 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 use. The leader hose and fittings connected to leader hose will become very
HOT during and after use. If necessary, wear heat resistant gloves to handle fittings, air line, and
leader hose.
