Manual Ram Lock; Install A Platen Inflatable Seal - Graco SaniForce Operation

Manual Ram Lock

To reduce the chance of injury from the unexpected
lowering of the ram while changing drums or
working near the raised ram, engage the manual
ram lock.
The manual ram lock operation is performed using
the pin and collar at the bottom of the stop rod to
engage the bracket on the top of the air cylinder
closest to the control panel.
1. Raise the ram to the top of its travel.
2. Move the manual lock to the bracket on the right
air cylinder, lift the collar, engage the pin into the
notch of the bracket, and lower the collar over
the bracket.
NOTE: If the ram has not been lowered to cause
the pin to engage the bracket, the collar at the
bottom of the lock arm will keep the lock arm in
position over the bracket.

3. To disengage the manual lock arm, lift the collar
above the bracket and move the lock arm away
from the bracket and back onto the storage
bracket on the platen support rod so that the
manual lock arm is restrained from undesired
movement.
NOTE: It may be necessary to raise the ram if
the pin of the lock arm is firmly engaged in the
bracket notch.

Install a Platen Inflatable Seal
This procedure assumes that no inflatable seal is
currently installed on the platen and the platen is
attached to the drum unloader assembly. If the platen
is detached from the pump lower, the inflatable seal
can be installed entirely from the top of the platen.
If there is currently a seal installed, to remove the
inflatable seal, read the procedure below to become
familiar with the steps, and then perform in reverse
order.
1. Raise the ram assembly to full height and engage
the ram lock to prevent inadvertent ram lowering.
2. At the rear of the platen, insert the inflation tube
through the access hole in the recessed groove
and ensure that the hose protrudes out of the
hole on the top of the platen.
NOTICE
To prevent damage to the seal or seal air
hose, ensure that the inflation hose is properly
centered in the platen hole.
3. Carefully center the inflation hose in the hole
and press the seal into the platen groove. A
flat is provided on the platen retaining flange to
aid installation. Hold the seal in place and work
around one side of the platen, working the seal
into the platen groove. Repeat on the other side
of the platen.
NOTE: A food safe lubricant can be used to
assist in sliding the seal over the platen lip, but is
not required.
4. At the front of the platen, work the remainder
of the seal over the platen lip, working to install
the seal into the remaining portion of the platen
groove.
5. Verify that the seal inflation tube is properly
positioned in the hole at the back of the platen.
6. Attach the air supply for the seal.
7. Disengage the ram assembly lock.
