turning the screwjack counterclockwise, until the
indicator lamp is no longer lit.

platform. Platform should not elevate.
DO NOT use a machine that elevates when

EMERGENCY LOWERING
If the platform should fail to lower, NEVER
climb down the mast.
Ask a person on the ground to open the Emer-
gency Lowering Valve to lower the platform. This
valve is located through a cutout in the power unit
cover on the left side of the mast.
1. Pull the knob out and turn one quarter turn
either direction to open the Emergency Lower-
ing Valve.
2. To close the Emergency Lowering Valve, turn
the knob until it snaps back in.
NOTE: Once the platform is fully lowered, be
certain that the Emergency Lowering Valve is
closed again. The platform will not elevate if the
Emergency Lowering Valve is open.
