Problem Possible Cause Solution
The OIL LED is on. • Oil tank is empty
• A shut-off valve at the outlet of
the oil tank might be closed
• Oil flow from the oil tank may be
obstructed; the oil filter may be
clogged
• Oil blockage between the
Dripmaster outlet pipe and the
line-shaft—excessive oil briefly
flows from a built-in overflow
hose
• Refill the oil tank
• Open the shut-off valve
• Change the oil filter, or clean out
any obstructions in the pipe
between the oil tank and the
Dripmaster inlet
• Clean out any obstructions in
the pipe between the
Dripmaster outlet and the line-
shaft.
Note: Reset the system after fixing
the problem. See Resetting
the Dripmaster on page 18.
After restoration, the
counter displays 00, and the
drip search function causes
the motor to open the
needle valve until drops are
detected, after which normal
stabilization occurs.
