relationship of the handler frame to the front axle. Move
the lever to the right to tilt frame to right or move lever to
left to tilt frame to left.
Outrigger Levers: These levers raise and lower out-
riggers. Move levers forward to lower or pull levers to
rear to raise outriggers.
Parking Brake Light: This light glows to indicate that
