SECTION 4: MAINTENANCE
ENGINE MAINTENANCE
Engine maintenance procedures and schedules can be found in the engine manual. Follow those instruc- tions for performing engine maintenance.
Using the Engine Oil Drain Valve
•Locate the oil drain valve on the left side of the engine.
•Pop open the protective cap on the end of the oil drain valve to expose the oil drain port. See Figure 21.
•Push the oil drain hose (packed with this man- ual) onto the oil drain port. Route the opposite end of the hose into an appropriate oil collection container with a capacity great enough to collect the used oil (62 oz.- ZT42; 80 oz.- ZT50).
Protective
Cap
•If acid spills on clothing, first dilute it with clean water, then neutralize with a solution of ammonia/ water or baking soda/water.
•NEVER connect (or disconnect) battery charger clips to the battery while the charger is turned on, as it can cause sparks.
•Keep all sources of ignition (cigarettes, matches, lighters) away from the battery. The hydrogen gas generated during charging can be combustible.
•As a further precaution, only charge the battery in a well ventilated area.
•Always shield eyes and protect skin and clothing when working near batteries.
WARNING: Batteries contain sulfuric acid and may emit explosive gases. Use extreme caution when handling batter- ies. Keep batteries out of the reach of children.

HYDROSTATIC TRANSMISSION MAINTENANCE
The zero turn tractor is equipped with dual integrated hydrostatic pumps, motors, and transaxles that are sealed and do not require regular maintenance. All service work on the hydrostatic transmissions should be performed by your White Outdoor dealer.
GENERAL BATTERY INFORMATION
WARNING:
•Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.
•Should battery acid accidentally splatter into the eyes or onto the skin, rinse the affected area immediately with clean cold water. If there is any further discomfort, seek prompt medical attention.
The battery is located on the right/rear of the tractor beneath the seat box frame.
To remove the battery:
•Push downward on the top rear of the battery holddown rod and pull the bottom rearward to release it from the tab in the frame. Rotate the holddown rod upward and maneuver out of the hole in the seat box.
•Remove the hex cap screw and sems nut secur- ing the black negative battery lead to the negative battery post (marked NEG). Move the cable away from the negative battery post.
•Remove the hex cap screw and sems nut secur- ing the red positive battery lead to the positive battery post (marked POS).
•Carefully lift the battery out of the tractor.
Install the battery by repeating the above steps in the reverse order.
WARNING: Always connect the positive lead to the battery before connecting the negative lead. This will prevent sparking or possible injury from an electrical short caused by contacting the tractor body with tools being used to connect the cables.
