Autoquip HORIZONTAL BALL SCREW - Manual (Page 12)

LIFT BLOCKING INSTRUCTIONS
1. Remove all load from the platform. Never block the lift when loaded.
2. Raise the platform sufficiently for the base rollers to rollback past the flip-over
maintenance locks, located on the base frame of the lift.
3. Engage both maintenance locks by flipping them over (see Figure 7).
4. Lower the platform until the base rollers just come into contact with and rest against
the maintenance locks.
5. Always shut off the main electrical switch, when blocked, to prevent someone from
turning it on.
DANGER !
To avoid personal injury, NEVER go under the platform until the load is
removed and the lift is securely blocked in the open position.
6. To remove the maintenance locks, raise the platform by activating the “UP” switch to
provide sufficient clearance for the removal of the maintenance locks.
DANGER !
Maintenance locks that are bent, damaged, or non-functional must be
replaced immediately to avoid personal injury. Contact the Autoquip
Service Department for replacement parts and installation instructions.
