WARNING
WARNING
MOVING PARTS HAZARD
Moving equipment parts can cause per-
sonal injury, including severing of hands
or fingers. Make sure all personnel are
clear of moving parts before operating
the equipment.
WARNING
To reduce risk of injury or damage to
equipment, be sure to tighten the bleed
stick after bleeding the air. Otherwise hot
material will leak out of the opening.
CAUTION
The use of a non-compatible lubricant can cause
material contamination or inadequate performance.
Use only a lubricant compatible with the material to
be pumped. Check with the material supplier for a
recommended lubricant.
CAUTION
To help avoid damage to equipment, do not use a
drumpail of material that has been dented or other-
wise damaged; damage to the follower wipers may
result.
1. Make sure the follower plate is high enough to put
a drumpail of material under it.
2. Open a drumpail of the proper material and locate
it under the elevated follower plate.
NOTE: Whenever drumpail changes are required, re-
move the cover from the drumpail of new ma-
terial by holding it level and lifting it straight up.
Tipping the cover may allow accumulated dirt
to spill into the drumpail, which may result in
damage to the equipment.
3. Lubricate the follower wipers with a lubricant com-
patible with the material to be pumped. Check with
your material supplier for compatibility.
4. Before lowering the pump into the drumpail, make
sure that nothing is between the follower plate and
the drumpail, or between the ram tie bar and the
top of the ram posts.
5. Lower the pump into the drumpail of material.
a. To lower the pump and follower into the drum-
pail, move the ram hand valve lever to the
DOWN position and slowly adjust the air regu-
lator.
b. As the follower enters the drumpail, loosen the
bleed stick. Removing the bleed stick allows
trapped air between the follower plate and the
top of the material to escape.
c. When air stops exhausting from the bleed stick
port, replace and tighten the bleed stick.
6. Place a material waste container under the dis-
pense gun.
7. Slowly adjust the pump air regulator. This will start
the pump and fill the material passage.
8. Dispense material from the dispense gun until air-
free material is dispensed. Allow the system to
heat for approximately 30 minutes.
