9.7 Rubber Springs - Replacement
The rubber springs require periodic replacement.
NOTE
:
Exposure to abrasions, over-stretching and
heat build-up from prolonged operating cycles all
contribute to shorter spring life. Stop the Ho-Pac
during repositioning to help minimize heat-aging of
rubber.
CAUTION
Crush injury. Do not place hands or
fingers between mounting frame and
compaction plate during removal of
spring mounts.
Ensure all loads are adequately supported before
performing any service work.
CAUTION
Some components of the Ho-Pac are heavy. Use
approved lifting equipment to properly support and
stabilize loads.
NOTE:
If multiple mounts are to be replaced, it is
recommended to replace one mount at a time.
1.
Position Ho-Pac on flat, stable surface.
2.
Support top mounting frame to remove weight
from mounts.

9.8 Threaded Fasteners – Replacement &
Preparation
IMPORTANT
All threaded fasteners must be checked frequently
for loose, broken or missing bolts. Keep threaded
fasteners tight. Replace with new if missing or
damaged. Replacement fasteners must be the same
type and grade. Follow proper tightening procedures
and bolt torque. Failure to follow these instructions
when tightening can have serious consequences.

With a nut and bolt combination, a hardened
washer must be used under the element to be
turned. AND the element not turned must be
prevented from rotating during tightening.
x
All threads must be free of damage and foreign
debris. Surfaces to be bolted must be flat.
