Boom Adjustments
HC Boom Only
Boom Slides
The poly slides on the boom tend to wear over time. Adjust the pressure on the poly slides as
needed to compensate for wear.
To adjust the pressure on the poly slide pads, locate the large locknuts (located by each pad) on the
tank side of the slide tower. Tighten the locknuts to increase the pressure on the poly slide pads.
Tighten all the pads equally.
Boom Breakaways
The tension of the boom breakaways should be checked and adjusted as needed. If the tension on
the breakaways is too great, the boom may be damaged if it strikes a stationary object. Tightening
the nuts on the extension spring for the breakaway increases the tension. Turning the nuts out
decreases the tension. The springs are located between the primary and secondary boom wings.
Boom Level
If the boom does not hang level, secure the boom with an overhead hoist or other suitable means.
Loosen the six nuts on the bolts which hold the boom to the tower slides. These bolts fit through
slotted holes. Level the boom and retighten the nuts.
Boom Wing Alignment
Align boom inner and outer wings with the parallel connecting link. Remove the pin from the clevis
on the end of the link. Turn the clevis in or out on the threaded shaft intil the link is properly aligned.
Reinstall the pin.
