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 themagnetic switch.
It is recommended to have the power cord installed by a qualified electrician.
Refer to Fig.2 for power cord wiring diagram.
GROUNDING
FIGURE 1
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
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-INPROCEDURES*
NOTE: SERIOUS DAMAGE MAY RESULT IF THE FOLLOWING BREAKIN 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.
FIGURE 3
FIGURE 4
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 how
to fill the crankcase with oil.
4) Open the drain valve (A) Fig.5, turn it clockwise as shown, 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 counterclockwise. 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.
FIGURE 5
FIGURE 6

PIPING & COMPRESSOR CONTROLS
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 (A) Fig.7.
ADDITIONALREGULATORSANDCONTROLS
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.
OPERATIONCONTROLS
BALL VALVE OUTLET PRESSURE LEVER (B) FIG.7. This lever controls
the amount of pressurized air in the air delivery piping system.
CHECKVALVE (A) FIG.8. 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.9. The tank pressure gauge indicates
the reserve air pressure in the tank.
ON/AUTO-OFF SWITCH (B) FIG.9. Turn this switch ON to provide power to
the automatic pressure switch and OFF to remove power at the end of each
use.
PRESSURESWITCH (C) FIG.9. 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.
FIGURE 7
FIGURE 8
ASME SAFETY VALVE (D) 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.
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 clockwise to open (no pressure build-up) or counterclockwise to close
it (permits pressure build-up).
MAGNETIC SWITCH ((B) FIG.10). The magnetic switch has an automatic
thermal overload protector. If the motor overheats for any reason, the thermal
overload protector will shut off the motor. The motor must be allowed to cool
before restarting. Wait for motor to cool down, once motor is cool, restart.

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 undesireable 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 (D) 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 clockwise 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 (D) 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 counterclockwise 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)
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. 800 ml 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
FIGURE 11
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.
