400P-RV-AUTOMATIC ACCESSORIES:

45-Degree Extended Reach, Angled Chuck:

Open-ended air chuck allows reach into areas difficult to reach by hand. 

Connects to Tire Inflation Gun.

90-Degree Twist-on Chuck:

This open-ended air chuck can be attached to any inflation valve where there is limited clearance.

Primary Hose & Extension Hoses:

Dual hoses, with quick connect couplings.

Tire Inflation Gun:

Normally closed-ended chuck, (until lever is engaged) all air chucks attach to the Tire Inflation Gun 

with quick connect couplings.

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.

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.

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.
