2.6 DUMP CONTROL LEVER
• Always stop the machine before operating the dump body to the dump position.
• Position a signalman to ensure safety in the surrounding area, and follow his signals when carrying out the
dumping operation.
• Always operate the dump control lever slowly. If the dump body is suddenly stopped or it is allowed to hit the
frame when it is lowered, it will cause failures and will also cause problems of safety in the surrounding area.
• When leaving the operator’s compartment with the dump body raised, always lock the dump control lever.
In addition, use the safety bar to prevent the dump body from coming down.
Even when the engine is stopped, it is possible to lower the dump body.
[1] DUMP CONTROL LEVER
Dump control lever (1) is used to raise and lower the dump body.
There are three operating positions: RAISE, HOLD, and LOWER.
• RAISE: The dump body is raised.
• HOLD: The dump body is stopped and held in position.
• LOWER: The dump body is lowered.
When the control lever is released, it automatically returns to the HOLD
position.
[2] DUMP CONTROL LEVER LOCK
Lever lock (2) is used to hold the dump control lever at the HOLD position.
2.7 DUMP BODY SAFETY BAR
• If it is necessary to go under the dump body to carry out inspection and maintenance, always use the safety bar
to prevent the dump body from coming down.
• When using the safety bar, check that the bar is fitted securely to the dump body holder.
• The safety bar is a safety device used during inspection and maintenance. Do not use the safety bar to support
the dump body when replacing the dump cylinder, valve, hydraulic hoses, or other equipment.
In such cases always support the dump body with a crane.
Safety bar (1) is a device to ensure safety during operations, and is used when
going under the dump body to carry out inspection and maintenance.
