1. Follow the Before Servicing procedure, page 31.
2. If you are only replacing the corner seals (21)
and not the ram plate seal (501, remove the rivet
(22) and replace each corner seal individually. Do
not remove all 4 corner seals at the same time or
the ram plate seal may move out of place. Be care-
ful not to puncture the ram plate seal. Skip to step 8.
If you are replacing the ram plate seal (501),
remove the rivets (22), then remove all 4 corner
seals (21). Check the corner seals for damage and
replace if necessary.

supply tube (14).

tool to avoid damaging the seal. Carefully disen-
gage the air stem from the hole in the ram plate

plate (502) hole. To avoid puncturing the new seal,
carefully slide the seal in place around the ram
plate.
