Lubricator Operation
1. Turn power switch (8) ON to activate pump (1).
Grease is sucked up and supplied to high-pressure
grease gun (3).
IMPORTANT: When pump (1) begins to suck grease, any
air inside pump (1) will be mixed in, making
grease turn whitish. Open check valve cock
(2) to bleed this air-mixed grease. Securely
close check valve cock (2) when all air-
mixed grease is bled out.
2. Get high-pressure grease gun (3) and pay out the hose
from hose reel (4) to the length required.
3. Press hydro-chuck (5) protruding from high-pressure
grease gun (3) into a grease fitting and pull the lever to
discharge grease.
4. Release the lever when greasing is complete; grease
discharge will stop.
IMPORTANT: When detaching hydro-chuck (5) from
grease fitting (7), grease fitting (7) tip may
break unless a special care, is taken, as
follows:
• Tilt nozzle (6) a little so as to release the
connecting pressure applied to hydro-
chuck (5).
• Slowly detach hydro-chuck (5) from grease
fitting (7).
5. When all greasing work is complete, turn power switch
(8) OFF, then pull grease gun (3) lever to release
remaining pressure from grease gun (3), pump (1), and
the hose so as to ensure long life of the components. A
little grease will be discharged at this time.
IMPORTANT: The hose has a limited service life.
Periodically inspect the hose for cracks,
grease leakage, or any other damage. If any
damage is found, replace the hose.
