The maintenance prop must be used during all service and maintenance where the lift must be raised

from using it.

raised position.
2. Rotate the maintenance prop up to a vertical position.
3. Lock the maintenance prop into position by inserting the Lock pin through the locking tabs and
prop (ref. Figure 7).
4. Lower the scissor securing the maintenance prop in the support position.
5. To remove the maintenance prop, raise the scissor high enough to disengage the maintenance
prop and provide clearance for the maintenance prop to swing down.
6. Remove the Lock pin (ref. Figure 7).
7. Rotate the maintenance prop down to the stored position.
