3. How to Operate the Machine
CAUTION
- Do not operate the gun lever with the discharge port facing to another person during machine
operation. A direct hit against the human body may result in an accident such as skin damage.
- Regarding a secondary accident such as hose damage that may be caused without shutting off of the
air supplied to the hose or installation contamination due to a leak from the valve or gun after
completion of the work or at night, the responsibility rests with the user side.
- When the pump causes a malfunction or operation stop, do not disassemble the pump thoughtlessly
and disassemble only necessary portions referring to the item pertaining to <Troubleshooting and
Corrective Measures> on page 4 and judging the situation properly.
<Note>
The electric grease pump runs continuously even if the grease gun closed. When internal pressure goes up to
28 MPa, the grease is relieved by relief valve automatically. Thus this unit is overload free. The grease returns
to pail through the outer tube.
1) Wipe the grease nipple to be used for greasing completely. After that,
push the hydro chuck of the high-pressure grease gun against the nipple
to perform chucking as vertically as possible. (Fig. 4)
2) Pull the lever of the high-pressure grease gun to supply grease. The
pump is automatically operated to supply grease. When grease is
normally injected, old grease will be squeezed out from the groove or
clearance bear the nipple.
3) After completion of grease supply, release the gun lever. The grease
supply will be stopped and the pump will also be stopped automatically.
4) Remove the hydro chuck of the grease gun. Since pressure is applied to
the hydro chuck, the head of the nipple may be broken if it is suddenly
pulled. Incline the hydro chuck to bleed the internal pressure and loosen
the claw bite, and the chuck can be easily removed. (Fig. 5)
5) After completion of greasing work or when the pump is not used for a long
time, be sure to shut off the supply air and bleed the internal air of the
pump, grease gun, and hose by operating the gun lever.
6) If the pump is suddenly started, it may be due to non-existence of grease
in the grease can or a cavity produced. Stop the greasing work and make
a check. If the grease is used up, replace the grease can.
[Replacing the grease can]
CAUTION
- When replacing the grease can, be sure to shut off the supply air for safety and pull the gun lever to
bleed the internal pressure of the pump and hose beforehand.
7) Unscrew the 3 wing bolts of the lid, and remove the pump unit from used the grease can and take out the follower
plate.
8) Remove the lid of a new grease can and place the follower plate on the grease horizontally and push the follower
plate by rubbing it until grease comes out from the central hole.
9) Insert the pump in the packing in the middle of the follower plate and set the lid on the pail can. Screw the 3 wing
bolts equally so fix the lid securely.
