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 drain plug under
hydraulic tank and allow tank to drain, reinstall drain plug. Fill tank with 20w - 50 motor oil to the
top of the baffle in the tank and replace cap. Block up the rear of unit until wheels will rotate freely
and start engine at a slow idle, move the motion control levers forward and run for several min-
utes. 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.
