Change Hydraulic Oil and Filter

The hydraulic system oil and filter must be changed ini­ tially at 200 hours and thereafter every 800 hours of op­ eration or seasonally, whichever comes first. NOTE: Change oil and filters every 400 hours if equipped with Model 30726 Hydraulic Kit. The hydraulic system is de­ signed to operate on anti–wear hydraulic fluid. The ma­ chines reservoir is filled at the factory with approximately 12 U.S. quarts (11.4 liters) of Mobil 424

hydraulic fluid (See Check Hydraulic Oil in this section for recommended fluids). Check level of hydraulic fluid before engine is first started and daily thereaf- ter.

1.Start engine, park machine on a level surface, lower implement to the shop floor, set the parking brake, and shut engine off.

2.Clean area around dipstick cap and remove cap from axle filler tube.

3.To ease access to axle housing drain plug, imple­ ment may be removed from traction unit.

4.Remove drain plug from axle housing and allow oil to flow into drain pan.

5.Clean area around hydraulic oil filter and remove fil­ ter. NOTE: Also replace filter for Model 30726 Hydraulic Kit.

6.Lubricate new filter seal and install filter.

7.Install drain plug in axle housing.

8.Through axle filler tube, fill axle to proper level with Mobil 424 hydraulic fluid. Install dipstick cap.

9.Start and run the engine at idle speed for about two minutes, raise and lower implement and turn the steer­ ing wheel lock to lock to purge air trapped in the system. Shut the engine off.

10.Let machine set for two additional minutes, then re­ move dipstick and check oil level in axle. If level is low, add oil until level matches groove in dipstick. If level is too high, remove drain plug and drain oil until oil level matches Full mark on dipstick.
