5.2 Adjusting the Height of the Chain Running Gears:
Caution Danger of Tilting!
In any case, two persons are required to adjust the height of the chain
running gears! Adjust the supports such that the aerial work platform
cannot fall over (max. inclination 14.5°, 26 %)! When adjusting the chain
running gear, always adjust the supports to wide support position
Caution Risk of Injuries!
With narrow-adjusted chain running gear, never loosen the locks if the
aerial work platform is supported high (chain running gear shoots down)!
Procedure for pushing the chain running gears inward (narrow adjustment):
To push in the chain running gear, jack it up by means of the supports until the chain
running gear has no ground contact anymore (max. 10-20 mm off the ground)
