INTERLOCK SAFETY SYSTEM
Theinterlock safety systems’s function isto prevent the enginefrom starting if theblades are engaged
or the drive levers are not locked in the thumb latches. It also causes engine shut down if the operator
falls from, or attempts to leave the operator position while the blades are engaged or the drive levers
are unlocked from the thumb latches. After the engine starts, the operator must hold down either the
left or right operator presence lever before engaging the blades or unlocking the drive levers from the
thumb latches. If neither operator presence lever is held down, the engine will stop. Check the function
of the safety electrical system on a regular basis.
1. Engine MUST kill if blades are engaged without at least one O.P. lever held down.
2. Engine MUST kill if the ddrive levers are unlocked from the thumb latches without holding down at
least one operator presence lever.
3. Engine MUST not start unless blades are off and the drive levers are locked in the thumb latches.
4. DO NOT operate the mower if the interlock safety system allows operation or starting in any
unsafe condition.
PUMP BELT
1. Before performing adjustments on pump belt, turn the mower off and disconnect spark plug
wire or wires.
2. Check tension on the belt. If it feels loose adjustment will need to be made.
3. Loosen the nut on the bottom of the idler pulley.
4. Slide the idler pulley against the belt, retighten the nut while applying pressure to the idler
pulley.

OPERATING INSTRUCTIONS
CONTROLS:
Be thoroughly familiar with all controls their function and how to operate them before operating the
mower.
1. Drive levers: Located on each side of the handle control direction of movement. The left
lever controls the flow of oil from the left hydro pump to the left wheel motor. The right lever
controls the flow of oil from the right hydro pump to the right wheel motor.
2. Ground speed lever: Located in the center of the console. Controls the forward speed of the
mower. Push the lever forward if you want to go faster, pull it back to go slower or pull it all the
way back to the neutral or stop postion.
NOTE: To begin motion the operator must move the ground speed lever forward before disengaging
the thumb latches. After you release the thumb latches allow the drive levers to move down at the
same time. The mower will move in a straight line in that direction.
Movement of the right lever down will cause the right wheel to rotate in a forward direction. Movement
of the left lever down will cause the left wheel to rotate in a forward direction. To stop forward travel pull
levers up into the stop position.
To turn right while moving in a forward direction pull the right drive lever up towards the stop position,
this will slow the right wheel and cause the mower to turn in that direction.
To turn left while moving in forward direction pull the left drive lever up towards the stop position, this
will slow the left wheel and cause the mower to turn in that direction.

MAINTENANCE
1. Engine oil level: Check daily with engine cold and on a flat surface. Remove the dipstick and
wipe clean. Reinsert the dipstick all the way,but do not screw down. Remove the dipstick and
check oil level. If oil level is low add oil. Use engine manufacturers specs for type of oil.
2. Pump drive belt: Stop engine and remove key. Check the tension on the belt.
3. Mower blades: Stop engine and remove key. Inspect blades and sharpen or replace as needed.
Check daily or more often if needed. The machine requires more power with dull blades and
gives a poor cut. If blades get bent, replace them. Blades shouldn’t have any notches from
hitting objects. The air foil on top of the blade should be sufficient to raise the grass for
cutting. If blades are in good condition, sharpen at an angle of 22 to 28 degrees about 2-1/2
inches in from the tips. Note: After sharpening, check blades for proper balance, if needed
correct balance to prevent excessive vibration.
4. Safety interlock system: Check daily and never operate the mower if this system is not func-
tioningproperly.
5. Hardware: Stop engine and remove key, thoroughly inspect the entire machine for any miss-
ing 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 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.
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 15w - 50 mobil1.
9. Tire pressure: Check every 25 to 50 hours. Pressure in all four tires should be 15 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 thor-
oughly before greasing)
13. Fuel filter: Replace every 100 hours or as needed.

15
MAINTENANCE
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
Yazoo/Kees p/n 102606, filter which has a bypass valve and the correct micron filter.
Remove the cap nut from the bottom of the tank and allow the tank to drain, reinstall the
cap nut. Fill tank with 15w - 50 mobil1, 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 respond an air lock has occured within the hydraulic system. Bleed air
from lines, or let stand overnight to allow the air to dissipate out of the oil. Retry re-
sponses & check the oil level.
Note: Serious damage to the pumps and wheel motors can occur if the system is run with an air
lock.
