4.1
External Power Unit
External power units should be placed within thirty feet (hose length) of the machine to avoid
excess pressure drops. External power units must be protected from moisture and weather.
4.2
Pit Installation
Do not install this machine in a pit unless the machine has been designed for such
installation. Shear points exist and can cause severe injury. Platforms traveling
below floor level may require guarding in accordance with ANSI MH 29.1. Guarding
must be installed before operation.
1. Verify that the pit dimensions match the pit plan.
2. Verify that pit is clear of tools and other debris before lowering the machine into the pit.
3. Follow General Installation instructions to complete the installation.
