PRESSURE SWITCH BUTTON:
The compressor is built with a pressure switch combining stop button
/ start function. Find it in the upper side. The button shall be set in
the "UP" position to start the compressor and in the "DOWN" to
turn-off. (See gure A)
A
NOTE: Before starting the compressor any compressed air remaining
above the piston and in the feeding pipe shall be discharged. Press
the pressure switch button and lift it again into the "I" (ON) position.
The motor will start immediately.
AUTOMATIC OPERATION
Once the compressor is running it will automatically stop and start.
Your compressor is built with a factory preset pressure switch. It
stops the motor when the tank pressure reaches its maximum
operation pressure and starts the motor automatically when the tank
pressure lowers to the preset pressure.If necessary, to stop the
compressor before it reaches the cut-out pressure,
the switch button must be pressed. (See gure B).
B
COMPRESSOR RELIEF VALVE: The button in the upper side of the
black pressure switch activates a small check valve. It relieves air
from above the piston and the tank-feeding pipe. Press the button
now and then to assure the valve is functioning and relieving air
correctly.

MAINTENANCE
Maintenance made in a regular basis will assure maximum ef ciency
for a long period of time.
Preventive daily maintenance
OIL: Check oil level in the casing
and re ll if necessary. If the
compressor is not used every day,
check the oil level in the casing
before starting. Replace oil after
500 hours.
(See gure c).
WATER: Due to air condensation water gets
stored in the tank bottom. Drain using the
purge valve found in the lower side of the
compressor tank. Unscrew the warped ring to
drain and tighten back before starting the
compressor. (See gure D).
CAUTION: The pressure of tank must be less
than 10 PSI (68.9 kPa) when drain the tank.
LEAKS: Double-check to detect leaks in the compressor, connections,
feeding pipes and couplings. Reseal if necessary. Keep in mind that
even a very small leak could waste compressed air. Is an extra cost
in energy used and will reduce the compressor duty life.
SCREWS IN THE CYLINDERS HEAD: These shall be checked and
tightened after the rst day of operation, after 50 hours and later on,
every 4 months. The cylinder head shall be completely cold before
this operation. Torque value is 23 Nm (16.96 Lb-ft).
AIR FILTER: Inspect, and
clean blowing with
compressed air. If too
contaminated replace
cartridge. (See gure E).
SAFETY VALVE: Is set to
activate and release air
pressure in the event of fault
on the pressure switch. (See
Figure F)

AFTER 200 HOURS
BELT TENSION AND ALIGNMENT: Isolate the main power. Check the
motor pulley and the pump ywheel. Verify alignment and see that
movement in the middle point of the "V" shaped belt shall not exceed
0.47" Also verify the motor and pump fastening screws are tightened.
Look for wear in the belt.
Double-check both pump
ywheel and motor pulley
is fastened in their
respective shafts. (See
gure G).
