Working on the Hook-Lift

Before working on a raised hook-lift the body must be removed from the hook-lift.
And the tip-support must be in place to support the hook-lift. Failure to do so, can
lead to serious injury or death.

The hook-lift has a tip-support, as illustrated
and described below.

This is used when working on the hook-lift. It
support the hook-lift when it is raised and act as
a safety measure in the event there is a
hydraulic failure.

The adjacent image shows where the tip-sup-
port (red) is stored.

The tip-support is anchored onto the hook-lift
using two red anchor points, as shown oppos-
ite. Locate these on the hook-lift and place the
tip-support between them before working on a
hook-lift.
