If electrical sparks from the compressor come in contact with flammable vapors, they may ignite, causing fire or explosion.

Restricting any of the compressor ventilation openings will cause serious overheating and could cause fire.

RISK OF BURSTING

WHAT CAN HAPPEN

1. Failure to properly drain condensed water from the tank,

causing rust and thinning of the steel tank.

2. Modifications or attempted repairs to the tank.

3. Unauthorized modifications to the unloader valve, safety

valve or any other components which control tank pressure.

4. Excessive vibration can weaken the air tank and cause

rupture or explosion.

RISK OF BURNS

WHAT CAN HAPPEN

HOW TO PREVENT IT

Always operate the compressor in a well ventilated area free of combustible materials, gasoline or solvent vapors. If spraying flammable materials, spray material at least 20 feet away from the compressor. An additional length of hose may be required.

Store flammable materials in a secure location away from the compressor.

Never place objects against or on top of the compressor.

Operate compressor in an open area at least 18 inches away from any wall or obstruction that would restrict the flow of fresh air to the ventilation openings.

Operate compressor in a clean, dry and well ventilated area.

HOW TO PREVENT IT

Drain tank daily or after every use. If the tank develops a leak, replace tank or get a new air compressor. Never drill into, weld or make any modifications to the tank or its attachments.

The tank is designed to withstand specific operating pressures.

Never make adjustments or parts substitutions to alter the factory set operating pressures.

For essential control of air pressure, you must install a pressure regulator and pressure gauge to the air supply system.

HOW TO PREVENT IT outlet tubes, can result in serious burns.

ELECTRICAL INFORMATION

WARNING!

ALL ELECTRICAL WIRING OF THIS COMPRESSOR MUST BE DONE BY

A QUALIFIED ELECTRICIAN.

FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY! ALL

ADJUSTMENTS OR REPAIRS MUST BE DONE WITH THE ELECTRICAL

PANEL CIRCUIT BREAKER IN THE OFF POSITION (IF HARD WIRED) OR

WITH THE POWER CORD DISCONNECTED (IF POWER CORD IS

INSTALLED) FROM THE POWER SOURCE. FAILURE TO COMPLY MAY

RESULT IN SERIOUS INJURY!

ELECTRICAL INSTALLATION

Hard Wiring from Electrical Source

This compressor does not have a factory installed power cord, normally stationary compressors are permanently hard wired directly from the electrical source to the magnetic switch (A) Fig.1 by a qualified electrician.

This compressor must be grounded, the green conductor of the cord used must be connected to the grounding screw inside the magnetic switch. See grounding information below.

Warning!

Do not attempt to hard wire this compressor yourself unless you are a qualified electrician. Overheating, short circuiting and fire damage will result from inadequate wiring.

Electrical wiring codes, local or provincial may differ from area to area.

Source wiring, plug and protector must be rated for at least the amperage and voltage indicated on the main technical nameplate. Use a slow blow fuse type D or a circuit breaker.

Installing 240V Power Cord

A properly sized 240V 3 wire power cord (2 lines, 1 ground) having a ground conductor and plug may also be installed to the magnetic switch, the green conductor must be connected to the grounding screw in the magnetic switch. It is recommended to have the power cord installed by a qualified electrician. Refer to Fig.2 for power cord wiring diagram.

GROUNDING

This compressor must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current, to reduce the risk of electric shock.

WARNING: IF NOT PROPERLY GROUNDED, THIS MACHINE CAN

CAUSE ELECTRICAL SHOCK, PARTICULARLY WHEN OPERATED IN

DAMP LOCATIONS. TO AVOID SHOCK OR FIRE, IF THE CORD IS WORN

OR DAMAGED IN ANY WAY, HAVE IT REPLACED IMMEDIATELY.

MOUNTING AND

BREAK-IN PROCEDURES

MOUNTING

Warning! This compressor is not intended for outdoor installation. Never use the transport skid for mounting purposes.

Make sure you mount the air compressor in a clean, well ventilated area where the surrounding air temperature will not exceed 40 0 Celsius. Position the air compressor about 18 inches away from any wall. Make sure there is sufficient space to access the tank drain cock.

Floor mounting

This air compressor is extremely top heavy. Before operating, the air compressor feet (3) MUST be bolted to a flat, even, concrete floor. It is recommended to purchase rubber pads (not included) to absorb vibrations.

A flexible coupling (not included) should be installed between the ball valve and piping.

*IMPORTANT BREAK-IN PROCEDURES*

NOTE: SERIOUS DAMAGE MAY RESULT IF THE FOLLOWING

BREAK-IN INSTRUCTIONS ARE NOT CLOSELY FOLLOWED. THESE

PROCEDURES ARE REQUIRED BEFORE THE AIR COMPRESSOR CAN

BE PUT INTO SERVICE, AFTER REPLACING THE CHECK VALVE, AND

WHEN A PISTON OR A CYLINDER SLEEVE ARE REPLACED.

1) Make sure the pressure switch lever (A) Fig.3 is in the “OFF” position.

2) Make sure the compressor is properly wired to electrical source and grounded, if a power cord was installed, plug the power cord into a grounded 240V branch circuit receptacle.

3) Make sure the oil level in the crankcase reaches the centre dot of the oil sight glass (A) Fig.4, refer to maintenance section for instructions on fill the crankcase with oil.

4) Open the drain valve (A) Fig.5, turn it counterclockwise, this will prevent air pressure build-up in the tank.

5) Move the pressure switch lever (A) Fig.6 to “ON/AUTO”. The compressor will start.

6) Run the compressor for 15 minutes. Make sure the drain valve is open and there is no tank pressure build-up (tank pressure gauge at zero).

7) After 15 minutes, close the drain valve by turning it clockwise. The air receiver will fill tank to cut-out pressure and the motor then will stop. The air compressor is now ready for use. Proceed to the following “Piping” instructions.

PIPING

Warning! Never use plastic (PVC) pipe for compressed air. Serious injury or death could result.

Any tube, pipe, or hose used must have a pressure rating higher than 150

PSI. Minimum recommended pipe size, keep in mind that a larger diameter pipe is always better:

Up to 50 feet long use 1/2”.

Greater than 50 feet use 3/4”.

The pipe gets installed to the 1/2” ball valve (B) Fig.6.

PIPING & COMPRESSOR CONTROLS

ADDITIONAL REGULATORS AND CONTROLS

Since the air tank pressure is usually greater than that which is needed, an air pressure regulator should be employed to control the air pressure ahead of any individual driven device. An air control unit which combines the function of air regulation, moisture and dirt removal should be used.

OPERATION CONTROLS

CHECK VALVE (A) FIG.7. When the air compressor is operating, the check valve is “open”, allowing compressed air to enter the air tank. When the air compressor reaches its “Cut-Out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank.

TANK PRESSURE GAUGE (A) FIG. 8. The tank pressure gauge indicates the reserve air pressure in the tank.

ON/AUTO-OFF SWITCH (B) FIG.8. Turn this switch ON to provide power to the automatic pressure switch and OFF to remove power at the end of each use.

PRESSURE SWITCH (C) FIG.8. The pressure switch automatically starts the motor when the tank pressure drops below the factory set “Cut-In” pressure.

It also stops the motor when the air tank pressure reaches the factory set

“Cut-Out” pressure.

ASME SAFETY VALVE (A) FIG. 9.

If the pressure switch does not shut off the air compressor at its cutout pressure setting, the safety valve will protect against high pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch cut-out setting).

WARNING!

: If the safety valve does not work properly, over pressurization may occur, causing air tank rupture or an explosion. Daily pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same ASME type of valve.

BALL VALVE OUTLET PRESSURE LEVER (B) FIG. 9.

This lever controls the amount of pressurized air in the air delivery piping system.

DRAIN VALVE (A) FIG.10.

The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use. Turn drain valve counterclockwise to open (no pressure build-up) or clockwise to close it (permits pressure build-up).

OPERATIONAL GUIDELINES

& MAINTENANCE

OPERATIONAL GUIDELINES

Moisture in compressed air

When humidity is high or when the compressor is in continuous use for an extended period of time, this moisture will collect in the air tank.

When using a spray gun or sandblast gun, this water will be carried from the tank through the hose and out of the gun as droplets mixed with the spray material. This will cause water spots in a paint job, especially when spraying other than water based paint. If sandblasting, it will cause the material to cake and clog the gun, rendering it ineffective. An optional air control unit with dirt and moisture removal should be used to prevent these undesirable results.

MAINTENANCE

Before doing any maintenance or adjustments to your air compressor, the following safety precautions should be taken:

- Turn power off (turn circuit breaker off or unplug power cord), drain air tank of pressure.

After Use:

1) Set the “On/Off” lever to the “OFF” position.

2) Pull ring on safety valve (A) Fig.9, allowing air to bleed from the tank until tank pressure is approximately 20 PSI. Release safety valve ring.

3) Drain water from air tank. Open drain valve (A) Fig.10, turn it counterclockwise to open.

WARNING!

: Water will condense in the air tank. If not drained water will corrode and weaken the air tank causing a risk of air tank rupture.

NOTE: If drain valve is plugged, pull ring on safety valve (A) Fig.9, and hold until all air pressure has been released. The valve can then be removed, cleaned, and reinstalled.

4) After the water has been completely drained, turn drain valve clockwise to close.

Daily or before each use

1) Check oil level. Oil level must be in the centre of the red dot of oil sight glass.

2) Drain condensation from tank.

3) Check for any unusual noise or vibration.

4) Be sure all nuts and bolts are tight.

Monthly

1) Inspect air system for leaks by applying soapy water to all joints. Tighten those joints if leakage is observed.

Initial oil change must be done after the first 100 hours

1) Once initial oil change is done after 100 hours of operation, change oil every

300 hours or 3 months, which ever comes first. See changing oil instructions.

2) Replace oil more often if used near paint spraying operations or in dusty environments.

CHANGING OIL (ORIGINALLY FILLED WITH SAE 20W OIL (ISO 68)

FIGURE 11

To change oil, oil must be drained from the crankcase by removing oil drain bolt

(A) Fig.11. Drain oil and replace oil drain bolt. To fill the crankcase with oil, first unscrew and remove oil fill cap (B), pour air compressor oil

(approx. 1.2 litres of SAE 30 weight non-detergent oil) into oil opening until the oil level reaches the red dot at the centre of the oil sight glass

(C). Reinstall the fill cap (B).

KEEP COMPRESSOR CLEAN

Periodically blow out all air passages with dry compressed air. Clean all parts with a soft damp cloth. CAUTION : Wear safety glasses while using compressed air.

REPLACING/TENSIONING DRIVE BELT

If the drive belt needs tensioning, the belt should be adjusted so when pressure is applied in the centre, there is approximately 1/2” slack. See Fig.12.

1) To install a new belt, remove the outer belt guard by removing the 3 hex. bolts that secure it. Loosen motor mount bolts and slide motor towards the pump, remove belt.

2) Install proper replacement belt, slide motor away from pump to provide recommended tension, align pulleys and fasten motor mount bolts.

3) Reinstall belt guard. Belt tension should be checked after 20 hours of operation. Check belt tension monthly thereafter.
