Joab Hookmaster, Manual

Page: 16 / 59

Do not tip, load, or unload bodies when the
vehicle’s axles are raised.
Do not make any modifications to the hook-lift
as this can effect its structural properties. If a
modification is required, contact JOAB for
advice before making a modification to the
hook-lift.
Emergency Operation
NOTE! when using the emergency operating system, the hook-lift's safety system is
disengaged. Caution must be taken! When the safety system is disengaged it is pos-
sible to damage the hook-lift or cause injury. Before using the emergency override
make sure that you are fully aware of its operation.
In the event of a failure in the hook-lift’s control
system it is possible to operate the hook-lift via
the hydraulic block, as shown opposite. An
emergency operating lever is supplied with the
hook-lift for this purpose. This is normally
placed in the driver's door.
If in any doubt about the use of the emergency
override, contact JOAB for advice before using
it.
