3.5 Bleeding air from Platform leveling system

If the platform does not stay level even after adjustment, air may have entered the platform leveling system. In this case, bleed air as follows.

(1) Set up the machine on firm and level surface, and set the boom horizontally, then extend the boom about 1 meter (3ft – 3in).

Danger: Do not allow any person or object on the platform when bleeding air.

(2) Pull the platform level adjust lever while pushing down the lock lever located beside the lower control box.

(3) Hold the dead-man switch in its ON position and operate the boom telescope switch to fully tilt the platform backward and forward several times.

(4) After adjusting the platform level, return the platform level adjust lever to its original position.

(5) Repeat the boom raising, lowering and telescoping operations several times and make sure that the platform stays level.
