Check in ALL directions, including above the work platform, for obstructions and electrical conductors.
Protect the control console cable from possible damage while performing checks.
1. Move the machine, if necessary, to an unobstructed area to allow for full elevation.
2. Pull Chassis Emergency Stop Switch to the ON position.
3. Pull Platform Emergency Stop Switch to the ON position.

approximately 2,1 m (7 feet). BLOCK THE ELEVATING ASSEM-
BLY AS DESCRIBED ON page 12.
6. Visually inspect the elevating assembly, lift cylinder, cables, and hoses for cracked welds and structural
damage, loose hardware, hydraulic leaks, loose wire connections, and erratic operation. Check for miss-
ing or loose parts.
7. Verify that the Depression Mechanism Supports have rotated into position under the machine. REMOVE
