Change Hydraulic Fluid and Filter

(Figure 26)

NOTE: Change hydraulic fluid and filter after

the first 75 hours of operation and then every

400 hours. Use 20W-50 engine oil with an SL

API classification.

1. Place container under oil filter to catch

oil.

2. Remove the filter guard and oil filter from

the transaxle.

3. Remove the oil drain plug or fitting from

the inlet port and allow the transaxle to

drain completely.

4. Clean the filter mounting surface and

then lubricate rubber gasket on new oil

filter with clean hydraulic oil.

5. Spin new oil filter onto filter housing until

it makes contact. Tighten oil filter

another 3/4 turn.

6. Install the filter guards removed in

step 2. Tighten the mounting screws to

65 lbf-in (7.3 N•m).

7. Fill with 20W-50 engine oil with an SL

API classification until oil appears at the

bottom of the drain plug (about 2 quarts

per transaxle). Install the drain plug and

tighten it to 180 lbf-in (20.3 N•m).

8. Repeat steps 1–7 for the other

transaxle.

9. Follow the instructions in “To Add

Hydraulic Fluid:” on page 25.

Purging the Hydraulic System

1. With the unit up to and facing a wall, jack

up the unit so that both drive wheels are

off the ground.

2. Disengage the parking brake and put the

transaxle bypass levers in the neutral

position (see MOVING UNIT

MANUALLY on page 16).

3. Start the engine and slowly move the

steering levers in forward and reverse

five or six times.

4. Stop the engine and put the transaxle

bypass levers in the drive position (see

MOVING UNIT MANUALLY on

page 16).

5. Start the engine and slowly move the

steering levers in forward and reverse

five or six times.

6. Stop the engine, check the oil level and

add oil as needed.

7. Repeat steps 2–6 until the transaxles

operate smoothly in forward and reverse

at normal speeds without excessive

noise.

Figure 25

The hydraulic fluid should be at the cold

fill line of the expansion tank.

WARNING: This adjustment

requires operating the engine.

Use extreme care to avoid

contact with moving parts and hot

surfaces. Be sure rear of unit is

well supported and secure before

starting engine.
