Mast
guard
If the mast
guard is improperly fastened, it
cannot adequately protect
platform occupants. Therefore,
make sure that hinge fasteners
(circled in the drawings) are
tightened to 35ft·lb of torque.
Retighten the connection to 35
ft·lb whenever:
1. The work platform is taken
out of storage:
 Raise the upper portion of
the mast guard, and then
 Tighten the bolts and nuts.
2. If the mast guard is bumped
or deflected from vertical.
 Immediately lower the
platform to the ground; then
 Straighten the mast guard
(return it to the vertical
orientation) and retighten the
bolts and nuts.

and bottom portions of mast guard.
