MAINTENANCE
5. Hardware: Stop engine and remove key thoroughly inspect the entire machine for any missing
or loose hardware. Check daily.
6. Air cleaner: Stop engine and remove key. Remove plastic cover and loosen wingnut on the 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.
7. Engine oil: Change oil to manufacturers specifications. Stop engine and remove key. Drain oil
when engine is warm. Thoroughly clean around cap before removing. Remove oil drain
cap from the right side of engine block and replace drain cap. Remove oil filter and replace. Put
a light coat of clean oil on the filter gasket before installing. Fill engine with oil using manufactur-
ers 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.
8. Hydraulic oil: Check daily. Thoroughly clean around cap. Remove cap. Oil level should be
1" below the bottom of the fill tube. If not, add oil. NOTE: Use only synthetic 15W - 50 Mobil 1.
9. Tire pressure: Check every 25 to 50 hours. Rear tires require 15 psi and caster tires 20 psi
10. Belts: Check every 25 hours. Stop engine and remove key. Check the condition of all belts.
12. Lubrication (every 25 hours): Caster tires and front caster pivots
(Clean grease zerk thoroughly before greasing)
13. Fuel filter: Replace annually or as needed.
14. Hydraulic filter and oil: Change every 500 hours or yearly. Stop engine and remove key.
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 Husqvarna 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 synthetic 15W - 50 Mobil 1. 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 occurred 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.
