4.6 Load and Safety Drop Stop Chain Replacement
(Normal Maintenance)
The materials required for the chain replacement are shown in Figure 4-6:
Step 1. Use the Down button to rest the cart’s boom / fixture on a supporting surface.
Ensure all of the boom / fixture weight is set down on the supporting surface.
Step 2. Using the Down button to slack the chain.
Step 3. Turn the cart’s power OFF and ensure that the cart is unplugged.
Step 4. Remove both chains from the chain nest. The bottom bolt releases the Safety Drop
Stop (SDS) chain and the top bolt releases the Load chain.
A 4mm allen wrench will be required to accomplish this.
(Refer to Figure 4-7)

disengaged from the chain nest.
