CAUTION:

T81389
T81389-UN-28JUN13

Avoid injury or death caused by objects falling on operator. Automatic cylinder extend feature (detent) must be deactivated before loader operation. If automatic extend feature is active, operator can unintentionally raise loader to full height and cause load to fall back on cab or operator. See Adjust Flow Rate and Timed Detent of Tractor SCVs and ICVs in Prepare the Tractor section.

Set tractor SCVs or ICVs to zero detent time or loader position before operating loader. See Adjust Flow Rate and Timed Detent of Tractor SCVs and ICVs in Prepare the Tractor section.

Set hydraulic flow rate for safe and smooth operation of loader. See Adjust Flow Rate and Timed Detent of Tractor SCVs and ICVs in Prepare the Tractor section.

Operate loader from operator’s seat only. Remain at controls until operating cycle is complete.

Use lock function when loader is not in use or when exiting tractor.

Oil flow limitations can prevent multiple loader operations at same time. The operation that requires the least amount of hydraulic force functions first.

Levers vary from tractor to tractor, but lever functions are the same, if the hoses are connected properly. See Identify Hose Connections in Service section for proper hose connections. See tractor Operator’s Manual for detailed setup and control of multi-function lever.

Multi-Function Lever: Lever returns to neutral position by itself from all positions except float. Pull lever back from float position to release into neutral.

Third function is operated with a rocker switch or button.

Some levers are equipped with an interlock switch actuator (H). The interlock switch actuator prevents loader operation if the operator's hand does not clasp the multi-function lever. If hand holds actuator open for longer than 10 minutes, lever operation is deactivated. Momentarily remove hand to reactivate lever controls. If hand clasps the lever when the tractor is started, lever operation is deactivated. Momentarily remove hand to reactivate lever controls.
