maintenance or repairs, disengage the PTO,
move the drive control levers fully outward in

unintended starting.
Engine
Refer to the Kawasaki Owner's Manual for all engine
maintenance intervals, procedures, specifications and
instructions.

Changing the Engine Oil

WARNING! If the engine has been recently run,
the engine, muffler and surrounding metal
surfaces will be hot and can cause burns to the
skin. Exercise caution to avoid burns.
To complete an oil change, proceed as follows:
1. Run the engine for a short time to warm the engine
oil. The oil will flow more freely and carry away more
impurities. Use care to avoid burns from hot oil.
2. Locate the oil drain port on the right side of the engine.
3. Pop open the protective cap on the end of the oil drain
valve to expose the drain port. Refer to Figure 6-1.
Remove the oil fill cap/dipstick from the oil fill tube.
4. Push the oil drain hose (packed with this manual) onto
the oil drain port. Route the opposite end of the hose
into an appropriate oil collection container with at least
a 2.5 quart capacity, to collect the used oil.
5. Pinch the tabs on the oil drain valve, then pull outward
to begin draining oil. See Figure 6-1.

6. After the oil has finished draining, push the end of
the oil drain valve back in, until the tabs click into
place. Re-cap the end of the oil drain valve to keep
debris from entering the drain port.
7. Replace the oil filter, and refill the engine with new
oil as instructed in the Kawasaki Owner's Manual.
Air Cleaner
Service the pre-cleaner and cartridge/air cleaner
element as instructed in the Kawasaki Owner's
Manual.

Spark Plug

The spark plugs should be cleaned and the gap reset
once a season. Refer to the Kawasaki Owner's Manual
for correct plug type and gap specifications.

Hydrostatic Transmission

The zero turn tractor is equipped with dual integrated
hydrostatic pumps/transaxles that are sealed and are
maintenance-free. Fluid levels cannot be checked and
fluid cannot be added or changed.
General Battery Information
WARNING!
• 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.
• 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 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.
• Batteries contain sulfuric acid and may emit
explosive gases. Use extreme caution when
handling batteries. Keep batteries out of the
reach of children.
