impurities. Use care to avoid burns from hot oil.

Locate the oil drain hose on the left side of the engine. 2.

Refer to Figure 6-1.

Route the free end of the oil drain hose toward an 3.

ZT 54 is equipped with a transmission oil expansion

reservoir. Under normal operating conditions, the oil

level in the expansion reservoir does not need to be

checked and no additional oil is needed.

If checking the reservoir oil level, proceed as follows:
