HYDRAULIC FLUID
WARNING: HYDRAULIC FLUID can
result in severe burns. Fluid in
hydraulic system can penetrate skin
and result in serious injury or death.
Be sure to stop the engine before
doing any work on hydraulic parts.
Keep body and hands away from pin
holes or nozzles which expel
hydraulic fluid when under pressure.
Use paper or cardboard, not hands,
to search for leaks.
Ensure all hydraulic fluid
connections are tight and all
hydraulic hoses and lines are in
good condition before applying
pressure to system.
FOREIGN FLUID INJECTED INTO
BODY can result in gangrene. Fluid
must be surgically removed within a
few hours by a doctor familiar with
this form of injury.
Check Hydraulic Fluid Level
Check the system with the unit cold and
parked on a flat, level surface.
Then run the unit for about one minute and
recheck the levels.
To Add Hydraulic Fluid
1. Remove the cap from the expansion
tank.
2. Fill the expansion tank with 15W-50
synthetic motor oil (p/n 00057100) or
equivalent until oil level reaches the cold
fill line on the tank.
3. Install the expansion tank cap and then
purge the system. See Purging the
Hydraulic System on page 22.
The hydraulic fluid
should be at the cold
fill line of the
expansion tank.

Change Hydraulic Fluid and Filter
NOTE: Change hydraulic fluid and filter after
the first 75 hours of operation and then every
400 hours. Use 15W-50 synthetic motor oil
(p/n 00057100) or equivalent.
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 15W-50 synthetic motor oil
(p/n 00057100) or equivalent 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 21.
