Pre-start checklist
A)
The dipstick will register the amount of oil in the
pump. (Fig. 2) 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 dipstick. If the oil level is low, replenish oil through
the filling hole so that the amount of oil will come to
a point between the maximum notch and the minimum
notch on the dipstick according to the OIL TYPE
CHART on page 8.

B) Remove any moisture in this compressor air tank.
Gradually open the drain cock and discharge the
drain. Close tightly when drained.
C) Make sure the engine switch is in the "OFF"
position.
D) Make sure the safety relief valve is working correctly.
(Fig. 3)
The safety relief valve is designed to prevent system
failures by relieving pressure from the system when
this compressed air reaches a predetermined level.
The safety relief valve is preset by the manufacturer
and must not be modified in any way. To verify the
safety relief valve is working properly, pull on the
ring. Air pressure should escape. When the ring is
released, it will reset.
E) Make sure all guards and covers are in place and
securely mounted.

OPERATION

A) Read safety warnings before performing operation.
B) When the toggle is in the upright position, all air
from this compressor is vented through the
discharge muffler (Fig. 4). This gives an easy start
feature. For normal operation, the toggle is in the
90° position.
