engine speed for a few minutes. Turn the steer-
ing wheel to the left and right a couple of times to
purge any trapped air out of the hydraulic system.
13. Shut o the power unit engine and allow the
power unit to sit for a minimum of ve minutes.
14. Check the hydraulic oil level. Refer to the Checking
the Hydraulic Oil Level section.
15. Inspect both of the hydraulic lters for signs of
leakage. If any leaks are evident, the lter may
need tightened further, or the lter may need to
be removed, the gasket and lter mount cleaned,
and the lter reinstalled following the procedures
for changing the lter.
16. Reinstall the hydraulic lter access cover.
Changing the Hydraulic Oil
1. Wash the underside of both the front and rear
transaxles thoroughly.
2. Park the power unit on a level surface and adjust
the steering to aim the power unit straight ahead.
3. Fully raise the front hitch and lower the 3 point
hitch (if equipped).
4. Shut o the engine and allow time for the hydrau-
lic system to cool.
WARNING
Hot oil can cause severe burns. Allow the oil tem-
perature to drop from hot to warm before draining
the hydraulic oil.
5. Place a drain pan (minimum 13.5 liter / 14 quart)
under the front transaxle.
6. Remove the drain plug (A) from the front trans-
axle and allow the hydraulic oil to drain from the
system. Loosen the cap on the hydraulic oil tank
to allow venting.
7.
A
If the transaxle is equipped with a pipe plug,
clean the drain plug and apply pipe sealant to the
threads, making sure to leave the last two threads
bare to prevent the thread sealant from contami-
nating the hydraulic oil. Reinstall the plug into the
front transaxle and tighten 1 to 1-1/2 turns past
nger tight (approximately 48-54 Nm / 35-40 ft-lbs
of torque).
If the transaxle is equipped with an o-ring plug,
reinstall the plug into the rear transaxle and
torque to 34-39 Nm (25-29 ft-lbs).
ATTENTION
Do not overtighten the transaxle plug. Overtighten-
ing can cause the transaxle case to crack.
8. Clean up any spilled oil and dispose of oil in accor-
dance with local laws.
ATTENTION
Oil is hazardous to the environment. Drain oil into
an approved container and dispose of used oil in
accordance with local laws.
9. If the hydraulic lters are being changed with the
oil, proceed to the Changing the Hydraulic Oil
Filters section before completing the remaining
steps in this section.
10. Add HydroTorq XL synthetic hydraulic oil to the
hydraulic oil tank until the oil level in the plastic
sight tube is within the proper range indicated by
the oil level decal.
11. Start the power unit and let it run at low idle
engine speed for a few minutes. Turn the steer-
ing wheel to the left and right a couple of times to
purge any trapped air out of the hydraulic system.
