Initial System Startup Procedure - Graco Uni-Drum Instructions Manual

Initial System Startup Procedure

To reduce the risk of serious bodily injury, such as
skin injection or splashing fluid in the eyes or on the
skin, always wear eye protection and protective
clothing when installing, operating, or servicing this
equipment.
Moving equipment parts can cause personal injury,
including severing of hands or fingers. Keep hands
and fingers away from the Follower Plate, Pump
inlets, and the drum when raising or lowering the
Follower Plate to reduce the risk of pinching or
amputating hands or fingers.
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.
To help avoid damage to equipment, do not use a
drum of material that has been dented or otherwise
damaged; damage to the Follower Plate wiper may
result.
To reduce risk of injury or equipment damage:
• Make sure all material hose connections are
secure.
• Do not pressurize the system until you have
verified the system is ready and it is safe to do
so.
