Vehicle movement is prevented unless the platform is fully stowed.
Verify platform lighting when lift is deployed and pendant illumination when lift is powered.
Lift operation shall be prevented unless the vehicle is stopped and vehicle movement is prevented.
An audio warning (and visual warning for public lifts) will activate if at least 25 pounds is on the threshold area when the platform is at least one inch below floor level.
The platform will not fold/stow when at least 50 pounds is on the platform. The inner rollstop will not raise if occupied by at least 25 pounds. The outer barrier will not raise if occupied by at least 25 pounds.
Lowering the platform beyond the inner rollstop locking position is allowed only when the inner rollstop is locked in position. Raising the platform more than 3” off of the ground is prevented unless the outer barrier is raised. Process, fold and insert completed document in the lift-mounted operator’s manual storage pouch.

Outer Barrier
Vehicle movement is prevented unless the platform is fully stowed.
Verify platform lighting when lift is deployed and pendant illumination when lift is powered.
Lift operation shall be prevented unless the vehicle is stopped and vehicle movement is prevented.
An audio warning (and visual warning for public lifts) will activate if at least 25 pounds is on the threshold area when the platform is at least one inch below floor level.
The platform will not fold/stow when at least 50 pounds is on the platform. The inner rollstop will not raise if occupied by at least 25 pounds. The outer barrier will not raise if occupied by at least 25 pounds.
Lowering the platform beyond the inner rollstop locking position is allowed only when the inner rollstop is locked in position. Raising the platform more than 3” off of the ground is prevented unless the outer barrier is raised. Process, fold and insert completed document in the lift-mounted operator’s manual storage pouch.
