Raising And Lowering The Ram; Changing Empty Drums - Graco 918316 Instructions-Parts List Manual

Raising and Lowering the Ram

CAUTION
An empty drum clamp can interfere with up and
down operation of the ram. When raising or lowering
the ram, make sure the drum clamp stays clear of
the follower assembly.
Fig. 1. The ram hand valve (30) on the ram air control
has 3 positions:
D Ram UP raises the ram
D Ram DOWN lowers the ram
D Ram OFF puts the ram in "neutral." Moving the
hand valve to OFF does not change the position of
the ram, but it stops the air pressure from attempt-
ing to move the ram either up or down.

Operation

Changing Empty Drums

To help avoid damage to equipment:
D Be sure to reload the empty supply unit with a full
drum of material immediately. Do not allow the
supply units to operate when empty, which would
cause a pump runaway and cause damage to the
system.
D Do not raise the ram and remove the follower
plate from the empty drum until you are ready to
immediately install the new drum.
D 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.
WARNING
MOVING PARTS HAZARD
To reduce risk of injury or damage to
equipment, take care when adjusting
blow off pressure. Too much pressure
can cause the follower plate to rise very
quickly or burst the drum. Too little pres-
sure can cause the ram to lift the entire
drum from the ground.
PRESSURIZED FLUID HAZARD
Bursts of material and air will exit the
bleed port! To reduce risk of injury or
damage to equipment, wear eye
protection, gloves and protective clothing
whenever working with this supply
system.
