SERVICE TRANSMISSION

Hydraulic Oil

Use only 5W-50 or 15W-50 all synthetic oil.

Checking Hydraulic Oil Level

IMPORTANT: Avoid damage! Check oil level in reservoir tank when oil is cold.

Do not overfill oil reservoir tank. Oil will expand during operation and could overflow.

1.Park machine safely. (See Parking Safely in the Safety section.)

A

MX15294

2.Unscrew and remove hydraulic reservoir cap/dipstick (A) from hydraulic oil reservoir.

3.Wipe dipstick with a clean cloth.

4.Install dipstick and allow the cap to rest on the end of the tube. Do not tighten the cap.

5.Remove dipstick and check oil level. Oil level should be at top mark on dipstick.

6.If necessary, add oil through oil reservoir filler neck.

7.Install cap on filler neck.

Changing Hydraulic Oil and Filter

IMPORTANT: Avoid damage! Contamination of hydraulic fluid could cause transmission damage or failure. Do not open oil reservoir cap unless absolutely necessary.

Severe or unusual conditions may require a more frequent service interval.

1.Park machine safely. (See Parking Safely in the Safety section.)

2.Allow engine and hydraulic oil reservoir to cool.

3.Clean area around reservoir filler cap, and remove filler cap from reservoir.

4. Remove cap (A) from oil reservoir tank filler neck.

B

MX15312

5.Turn hydraulic oil filter (B) counterclockwise to remove.

6.Allow hydraulic oil to drain into a drain pan with at least a 3.8 L (1.0 gal) capacity.

7.Apply a film of clean oil on gasket of new filter.

8.Install filter. Turn filter clockwise until gasket makes contact with mounting surface. Tighten 1/2 to 3/4 turn after gasket contact.

NOTE: Reservoir capacity is approximately 1.9 L (2.0 qt). Total system capacity is approximately 3.5 L (3.75 qt).

9.Fill oil reservoir with approximately 1.9 L (2.0 qt) of oil. 10.Install reservoir cap.
