BOARDING STAIRS - RIGHT

A set of boarding stairs is attached to the right side machinery house platform. When lowered, the stairs allow entrance to the machinery house from ground level. These stairs must be in their raised and latched position to enable the operator’s controls.

POWER STEP

The Power Step is one of the means for boarding the machine. It is located on the left side of the machinery house, near the center of the lower platform. Use the lock / release handle from ground level to lower the power step for boarding. When the power step is NOT latched in place, the operator’s controls are deactivated.
