Engine Oil Change; Transaxle (Transmission) Fluid Change - Husqvarna MZ 52 Operator's Manual

Engine oil change

NOTE: Change the engine oil when the engine
is warm. Refer to the engine owner's manual
for the correct replacement oil and filter change
recommendations.
WARNING!
To prevent burns, the engine should
be shut off and allowed to cool slightly
so the engine is still warm but the
surrounding surfaces and oil are not.
1. Park on a level surface. Apply parking brake.
2. Clean the dirt and debris from the area around the
oil fill cap.
3. Remove the cap/dipstick.
4. Locate the drain hose at the left rear of the
engine. Place an adequately sized container
under the end of the drain hose and remove the
oil drain plug.
5. Allow the oil to fully drain from the engine.
6. Replace the drain hose plug and tighten securely.
7. Fill the engine with new oil to the bottom of the fill
tube threads. Check the level with the dipstick.
8. Replace the oil fill cap securely when the oil level
is FULL.
9. Refer to the Service Journal for oil checking and
changing intervals.

Transaxle (Transmission) Fluid Change

This transaxle is designed with an external filter for
ease of maintenance. To ensure constant fluid quality
levels and longer life, an oil filter change interval of
every 200 hours is recommended.
The following procedure is performed with the
transaxles installed in the mower and the mower on
level ground. Apply the pump release valve for each
transaxle and set the parking brake.
1. Remove the three ¼" filter guard screws and filter
guard. Clean any loose debris from around the
perimeter of the filter. See illustration.
2. Place an oil drain pan (12" or more diameter and
8 qt. capacity is optimal) beneath the oil filter.
Remove the oil filter from the transaxle.
