830P
The 830P rear axle brake assembly is actuated by a pivoting lever bar. When the platform is raised the lever bar is allowed
to raise at the front, this lowers the frame at the rear and pivots the tire up until it makes contact with the stop weldment
on the frame. That along with the front caster brakes helps hold the machine in place while the platform is elevated.
Adjusting the Brake Actuator Bar (5)
The brake actuator bar (5) is adjustable within the slots at the top of the L side brackets. Moving the actuator bar up or
down allows the amount of pivoting action of the frame assembly.
This may need adjustment if when moving the machine, the wheel is dragging on the frame stop weldment (6) with the
platform fully lowered. Or the frame stop weldment (6) doesn’t engage the wheel (1) at all, when the platform is elevated.
Adjusting the actuator bar higher in the L bracket slots pushes the Pivoting Lever Bar (2) down further in the front and
raises the frame higher at the rear, thereby increasing the gap between the wheel (1) and the frame stop weldment (6).
Adjusting the actuator bar lower in the L bracket slots raises the Pivoting Lever Bar (2) up in the front and lowers the frame
at the rear, thereby decreasing the gap between the wheel (1) and the frame stop weldment (6).
