Initial Material Loading

WARNING
PRESSURIZED FLUID HAZARD
To reduce the risk of serious bodily inju-
ry, such as fluid injection or splashing
fluid in the eyes or on the skin, ALWAYS
wear eye protection and protective cloth-
ing when installing, operating, or servic-
ing this dispensing system.
MOVING PARTS HAZARD
Moving equipment parts can cause
personal injury, including severing of
hands or fingers. Make sure all person-
nel are clear of moving parts before
operating the equipment.
CAUTION
The use of a non-compatible lubricant can cause
material contamination or inadequate perfor-
mance. Use only a lubricant compatible with the
material to be pumped. Check with the material sup-
plier for a recommended lubricant.
To help avoid damage to equipment, do not use a
drum of material that has been dented or otherwise
damaged; damage to the follower wipers may result.
An empty drum clamp can interfere with up and
down operation of the ram. When raising or lower-
ing the ram, make sure the drum clamp stays clear
of the follower assembly.
For information about specific air pressure settings,
refer to the Graco system documentation.
1. Raise the follower plate high enough to put a drum
of material under it. Make sure the drum clamp
stays clear of the follower assembly.

Installation
2. Open a drum of the proper material and place it
under the elevated follower plate.
NOTE: Whenever drum changes are required, re-
move the cover from a drum of new material by hold-
ing it level and lifting it straight up. Tipping the cover
may allow accumulated dirt to spill into the drum,
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 drum, make
sure that nothing is between the follower plate and
the drum, or between the ram tie bar and the top
of the ram posts.
5. Lower the pump and follower into the drum of ma-
