: Risk of bursting.
If the safety valve does not work
properly, over-pressurization may
occur, causing air tank rupture or
an explosion.
D) Oil level should be checked on a daily basis to
ensure it does not exceed the maximum notch or
does not fall below the minimum notch on the oil
sight glass. (Fig. 8)
If the oil level is low, replenish oil through the fi lling
hole so that the amount of oil will come to a point
between the maximum notch and the minimum
notch of the oil sight glass according to the OIL
TYPE CHART on page 8.
CAUTION: Overfi lling with oil will cause premature
compressor failure. Do not overfi ll.
E) Make sure all guards and covers are in place and
securely mounted.


Turn off the engine switch before move the compressor.
Transport the compressor in the correct manner.

The operation of this compressor is automatic and is
controlled by the pilot valve which idles it when the
pressure in the air-tank reaches the maximum level and
restarts it when the air pressure drops during use to the
restart level.
The pilot valve is preset by the manufacturer and must
not be modifi ed in any way.

protection during use. Under some
conditions and duration of use, noise
from this product may contribute to
hearing loss.
Adjustment of working pressure
The air pressure coming from the air tank is controlled by
the regulator knob (Fig.11). Turn the pressure regulation
knob clockwise to increase discharge pressure, and
counterclockwise to decrease discharge pressure.
