1000 Series Ho-Pac
!! WARNING !!
Keep personnel away from the Ho-Pac
while in operation. Never operate the
Ho-Pac with workers in close proximity
to the Ho-Pac.
3. Activate the Ho-Pac with the switch
located in the operator’s cab.
!! CAUTION !!
Do not allow mounting frame to contact
base plate. Spring mount and frame
damage may result.
4. Apply down force with the carrier boom
to stretch spring mounts approximately
two-thirds their width (2.75 inch/70mm).
!! WARNING !!
Ground vibrations may collapse trench
walls. Stand clear.
5. As the material compacts, maintain a
constant down force with the carrier. For
larger areas, a repetitive, back and forth
sweeping motion is effective. The initial
pass is continued until compaction is no
longer apparent, typically 10 to 15
seconds.
!! CAUTION !!
Do not use the Ho-Pac to drag or move
dirt. Ho-Pac damage may result.
6. It may be necessary to try different lift
heights to determine the most effective lift
to achieve the desired level of compaction.
Compacted densities are reduced at the
bottom of excessively high lifts.
7. After compaction is complete, re-
position the Ho-Pac and/or carrier to
continue working. It is not necessary to
stop the Ho-Pac for minor carrier boom re-
positioning.
8. Repeat compacted lifts as necessary to
achieve finished grade.
