Warming Up Hydraulic System Oil

CQ262080-UN-11APR06

A - Hydraulic filter

Hydraulic system may operate more slowly when started in cold weather. This is due to the hydraulic oil not flowing as freely through the hydraulic system filter (A).

Steering also operates more slowly if the oil is not sufficiently warmed up.

Hydraulic system works normally once hydraulic oil is warmed up.

1. Start engine and run at idle to 1000 rpm.
2. Turn steering wheel fully to the right and fully to the left.
