Subject to modication
weight (50 ± 10)% of nominal lifting capacity specied by the manufacturer of the loader.
E.2 Test procedure
The test specied from E.2.1 to E.2.2 must be carried out according to each of the following conditions:
— position held after lowering the test load to a height of (1 ± 0.1) m (static test);
— position held after lifting the test load to a height of (1 ± 0.1) m (static test);
and at hydraulic system oil temperatures of between 40°C and 50°C.
E.2.1 The discharge device between the lifting rams and the control valve must be open
E.2.2 The total downward movement of the load must be measured at the implement's pivot point
E.3 Acceptance criterion
The total downward movement measured in E.2.2, during the rst 10 seconds, must not exceed:
— 100 mm, if the safety device is switched o󰀨 or manually deactivated;
— 300 mm, if the safety device is permanently activated.
After 5 min, additional downward movement must not exceed 100 mm. "
