METHOD FOR WASHING WASHABLE FLOOR

On the washable cab floor, it is possible to flush out the dirt directly with water.
Select a firm flat place for work.
When setting the machine at an angle, use strong blocks to stabilize the base of the machine and be
extremely careful when performing the work.
If the control lever is touched by accident, the machine may move suddenly, and this may lead to a seri-
ous personal injury or death. Always set the lock lever securely to LOCK position (L) before leaving the
operator's seat.
The cabin must be tilted towards the front left side.

During the operation, be careful not to get water on the monitor, connector, air conditioner and its filter
