800D OPERATION
Override Switches – The 800D features two RCL override
switches for RCL/ATB lockout conditions:
• On/Off Key Switch
• Push Button
The override key switch (Figure 2-1) is located behind a
sliding door on the left (driver’s side) crane operator controls.
Turning the key to the ON position will override the RCL/ATB
continuously until the key is turned to the OFF position. Do
not use override to continue lifting operations in an overload
or two blocked condition.
The override push button (Figure 2-2) is located on the
bulkhead between the crane’s two operator positions. Push
down the button to temporarily override the RCL/ATB
system. When the button is released, the RCL/ATB system is
no longer in override condition. Do not use override to
continue lifting operations in an overload or two blocked
condition.
