– Be sure that all decals are legible and in place
– Check the hydraulic power unit oil level
– Platform and Ground Control Panel must be
tested prior to use to determine that such
controls Panel are in safe working condition.

7. Aerial Lifts
 Work Place Inspection
– Do a visual inspection of the work area prior to
beginning work
• Hazardous locations
– Drop-offs or holes
– Bumps, floor obstruction or debris
– Inadequate surface support to withstand all load forces
imposed by the machine
• Clearance
• Overhead obstructions
– High voltage conductors
• The presence of unauthorized personnel
• Other possible unsafe conditions

8. Aerial Lifts
 Set up
– Position machine below desired work area
– Insert key and turn to the ground control
position
– Pull out the red Emergency Stop buttons at the
ground and platform controls
– For TMZ – 34/19:
• Pull the four (4) outriggers release handle and lower
