Important Information
When testing must be done in a closed area, activate the brakes and use blocks to prevent the machine from moving during the tests. Let only approved personnel on the machine. Keep other personnel off the machine and in view of the operator.
All tests and adjustments must be made with the oil in the hydraulic control system at normal operating temperature. Be sure the linkage adjustments are correct before making any tests.
