VIAIR 400P-Auto - Manual (Page 5)

SAFETY PRECAUTIONS:
1. Always inflate tires to manufacturer’s recommended tire pressures. Exercise extreme caution
when driving with aired-down tires. Reinflate tires before high-speed roadway travel.
2. Never exceed 20 M.P.H. when driving with partially inflated tires.
3. Never make sharp turns while driving with reduced tire pressure.
4. Re-inflate tires before high speed traveling onto roadways.
5. Use heat-resistant, minimum 200 PSI-rated working pressure extension hose.
Do not use aftermarket hoses with less than 200 PSI 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.
IMPORTANT: Always use an Open-Ended tire chuck such as the tire chuck equipped on the
Deflator/Inflator Coil Hose for tire inflation when using a compressor without an air tank.
CAUTION: Never touch the air compressor or fittings connected to the air compressor other than
the ON/OFF switch with bare hands during or immediately after use. The extension hose and fittings
connected extension hose will become very HOT during and after use. If necessary, wear heat
resistant gloves to remove hose from the compressor quick connect stud.
RECOMMENDATION:
This compressor is equipped with a poppet pressure release head valve. Head pressure will slowly
decrease (pressure will be released through the intake port of the compressor) to allow smooth
re-starts under pressure. If compressor’s is hooked up to power source and if the power switch
is left in the ON position for more than 7 to 8 minutes, Compressor will automatically turn on for a
short duration (3 to 5 seconds) to recover pressure due to built-in pressure switch. This is a normal
function of the compressor. Always shut off power to the compressor when the compressor is
not in use.
MAINTENANCE & REPAIRS:
Your air compressor is equipped with permanently lubricated, maintenance-free motor.
Never try to lubricate the compressor. Regularly clean dust and dirt from compressor cooling fins
and motor housing. All repairs should be performed by Manufacturer or Manufacturer authorized
service agencies only.
