air cleaner. Remove the foam pre-cleaner and wash or replace if needed. Inspect paper filter
and replace if dirty. Check every 25 hours,  daily if in very dirty conditions.  Fuel efficiency,
engine RPM, and available power goes down rapidly if the air filter is dirty.  Prolonged effects
could damage the engine.

oil when engine is warm. 

Thoroughly clean around cap before removing.

drain cap from the right side of engine block and replace drain cap. Remove oil filter and re-

manufacturers specs, see Kawasaki owner’s manual. Start engine and idle slowly to allow the oil
to recoat the interior of the engine and then inspect for leaks.

Clean around the filter and the drain plug on the bottom side of the tank. Remove the filter and
allow any oil to drain from the filter head. Then replace with new filter. Use only Yazoo/Kees p/n
102606, filter which has a bypass valve and the correct micron filter. Remove one of the hydraulic
lines from the bottom of the tank and allow the tank to drain, reinstall the hydraulic line. Fill tank
with 20w - 50 motor oil 1” below the fill tube and replace cap. Block up the rear of unit until wheels
will rotate freely and start engine at a slow idle, move the control levers forward and run for
several minutes. Stop engine and recheck oil level.  If wheels don’t response an air lock has
occured within the hydraulic system.  Bleed air from lines, or let stand overnight to allow the air
time to dissipate out of the oil.  Retry responses & check the oil level.  Note:  Serious damage to
the pumps and wheel motors can occur if the system is ran with an air lock.
