SERVICE PROCEDURE
ADJUST BODY POSITIONER
WARNING
If for any reason the maintenance is performed while the engine is running,
strictly follow the next rules.
One should sit on the operator's seat, preparing to stop the engine at
any moment, and contact with the other.
Set the dump lever at HOLD position to prevent the dump body from
moving. Also, set the parking brake valve lever at PARKING position to
prevent the machine from moving.
When working near fan or belts, do not bring your body or any materials
closer that can be dragged into.
Do not touch the gear shift lever or dump control lever. If you have to
operate the gear shift lever or dump control lever for any reason, always
give a signal to your fellow workers to tell them to move to a safe place.
If the materials or tools are dropped onto fan or belts, they fly away or
cut. Never drop or insert materials or tools.
With the positioner device, it is possible to automatically stop the dump body when it rises to the desired position (to
the dump body elevation). Adjust if it does not automatically stop or if the shock still remains.
