Operating Instructions

General Safety Information


General Safety

Since the air compressor and other components (material pump, spray guns, filters, lubricators, hoses, etc..) used, make up a high pressure pumping system, the following safety precautions must be observed at all times:

1. Read all manuals included with this product carefully..


Be thoroughly familiar with the controls and the

proper use of the equipment..

2.Follow all local electrical and safety codes as well as in the United States, the National Electrical Codes (NEC) and Occupational Safety and Health Act (OSHA)..

3.Only persons well acquainted with these rules of safe operation should be allowed to use the compressor..

4.Keep visitors away and NEVER allow children in the work area..

5.Wear safety glasses and

use hearing protection when operating the unit..

6.Do not stand on or use the unit as a handhold..

7.Before each use, inspect compressed air system and electrical components for signs of damage, deterioration, weakness or leakage.. Repair or replace defective items before using..

8.Check all fasteners at frequent intervals for proper tightness..


electrical equipment and controls can cause electrical arcs that

will ignite a flammable gas

or vapor. Never operate or repair in or near a flammable gas or vapor. Never store flammable liquids or gases in the vicinity of the compressor.


operate compressor without a

beltguard. This unit can start automatically without

warning. Personal injury or property damage could occur from contact with moving parts.

9.Do not wear loose clothing or jewelry that will get caught in the moving parts of the unit..

Compressor parts may be hot even if the unit is stopped.

10.Keep fingers away from a running compressor; fast moving

and hot parts will cause injury and/ or burns..

11.If the equipment should start to vibrate abnormally, STOP the engine/ motor and check immediately for the cause.. Vibration is generally a warning of trouble..

12.To reduce fire hazard, keep engine/ motor exterior free of oil, solvent, or excessive grease..

An ASME code safety relief valve

with a setting no higher than 150 psi MUST be installed in the tank for this compressor. The ASME safety valve must have sufficient flow and pressure ratings to protect the pressurized components from bursting.

See compressor specification decal

for maximum operating pressure. Do not operate with pressure switch or pilot valves set higher than the maximum operating pressure.

13.Never attempt to adjust ASME safety valve.. Keep safety valve free from paint and other accumulations..

Never use plastic (PVC) pipe for

compressed air. Serious injury or death could result.

Never attempt

to repair or modify a tank! Welding, drilling or any other modification will weaken the

tank resulting in damage from rupture or explosion. Always replace worn, cracked or damaged tanks.

Drain liquid from tank daily.

14.Tanks rust from moisture build-up, which weakens the tank.. Make sure to drain tank regularly and inspect periodically for unsafe conditions such as rust formation and corrosion..

15.Fast moving air will stir up dust and debris which may be harmful.. Release air slowly when draining moisture or depressurizing the compressor system..

Spraying Precautions

Do not spray

flammable materials in vicinity of open flame or near ignition sources including the compressor unit.

16.Do not smoke when spraying paint, insecticides, or other flammable substances..

17.Use a face mask /

respirator when spraying and spray in a well ventilated area to prevent health and fire hazards..

18.Do not direct paint or other sprayed material at the compressor.. Locate compressor as far away from the spraying area as possible to minimize overspray accumulation on the compressor..

19.When spraying or cleaning with solvents or toxic chemicals, follow the instructions provided by the chemical manufacturer..


VT6315, VT6358, VT6361


Refer to Figure 1 to locate the following items..

Pressure switch - Auto/Off Switch - In the auto position, the compressor shuts off automatically when tank pressure reaches the maximum preset pressure.. After air is used from the tank and drops to a preset low level, the pressure switch automatically turns the motor back on.. In the off position, the compressor will not operate.. This switch should be in the off position when connecting or disconnecting the power cord from the electrical outlet..

When the pressure switch turns the motor off you will hear air leaking out of the pressure switch unloader valve for a short time.. This releases the air pressure from the discharge tube and allows the compressor to restart easier..

Regulator - The regulator controls the amount of air pressure released at the hose outlet..

Discharge tube - This tube carries compressed air from the pump to the check valve.. This tube becomes very hot during use.. To avoid the risk of severe burns, never touch the discharge tube..

To avoid the risk of severe burns, never

touch the discharge tube.

Check valve - One-way valve that allows air to enter the tank, but prevents air in the tank from flowing back into the compressor pump..

Handle - Designed to move the compressor..

Never use the handle to lift the

unit completely off the ground. Handle is intended only for pushing or pulling product.

Belt Guard - Covers the belt, motor pulley and flywheel..


operate compressor without a

beltguard. This unit can start automatically without

warning. Personal injury or property damage could occur from contact with moving parts.

Tank Drain Valve - This valve is located on the bottom of the tank.. Use this valve to drain moisture from the tank daily to reduce the risk of corrosion..

Reduce tank pressure below 10 psi, before opening drain valve..

Tank Pressure Gauge - Indicates amount of air pressure stored in tank..

Hose Pressure Gauge - Indicates amount of air pressure in hose used to operate tools.. This pressure is increased or decreased by the regulator..


Handle Assembly - Handle may be pre-assembled on some units..
