Information

The PIWIS Tester II 9818 instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.

When changing the hydraulic fluid, the clutch system does not have to be bled using PIWIS Tester II. However, the air/leak test must be carried out and clutch adaptation must be performed using PIWIS Tester II.

Brake filling and bleeding device ATE WE 1096 must be connected.
The bleeder valve is located between the engine and drive motor at the bottom left.
Pull the dust boot -1- off the bleeder valve and attach the breather hose.
