Service Hoist Safety Props (optional)
The service hoist safety props must be set when any work is performed under a lifted body. This
feature comes with the service hoist option.
Safety props ensure that heavy body parts will not move inadvertently.
Setting the Service Hoist Safety Props
The safety props ensure that an empty body will not lower when you are working underneath it.
Figure 2 - 2 Service hoist safety props
To set the service hoist safety props:
1.
Make sure that there is enough clearance above the body to raise it safely and that the truck is on
safe level ground.
2.
Put the key to the “ON” position without starting the truck.
3.
Unlatch the 2 front body latches (see Figure 2 - 3).
Before unlatching them, measure the length of the spring.
Spring should be between 3.25” and 3.5” long.
Warning!
Always unload the body before setting the hoist safety props.
Danger!
Always set the service hoist safety props when performing maintenance underneath a
raised body. Failure to do so may result in severe injury, or even death.
