LUBRICATOR --- IF EQUIPPED
1. Lubricator Operation
(1) Turn power switch (8) ON to activate the pump (1).
Grease is sucked up and supplied to high-pressure
grease gun (3).
IMPORTANT: When the pump 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) Open front right cover (9), turn switch (10) ON.
(3) Take out grease gun (3) from front right cover (9). Get
high-pressure grease gun (3) and pay out the hose from
hose reel (4) to the length required.
(4) Press hydro-chuck (5) protruding from high-pressure
grease gun (3) into a grease nipple and pull the gun le-
ver (11) to discharge grease.
(5) Release the gun lever (11) when greasing is complete;
grease discharge will stop.
IMPORTANT: When detaching hydro-chuck (5) from grease
nipple (7), grease nipple (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
nipple (7).
(6) When all greasing work is complete, turn power switch
(8) OFF, then pull grease gun (3) lever to release remain-
ing 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.
NOTE: The hose has a limited service life. Periodically inspect
the hose for cracks, grease leakage, or any other dam-
age. If any damage is found, replace the hose.
