Mower Operation - Scag Power Equipment SWZU Operator's Manual

MOWER OPERATION

1. Read and understand the safety instructions before
attempting to operate this machine.
2. Before starting the engine:
* Check the oil level in the engine and the
hydraulic reservoir.
* Fill the fuel tank with clean, fresh, lead-free
gasoline.
* Open the fuel valve on the bottom of the fuel
tank.
Use gasoline with an octane rating no less than
87.
* The speed adjustment lever must be in
NEUTRAL.
* The blade clutch switch must be in the OFF
position.
* The neutral latches must be in the neutral lock
position.
* The key switch must be on.
* The parking brake must be on.
3. Start the engine:
* Choke as required. If the engine is cold, pull the
choke knob out. When the engine starts, slowly
push the choke in. If the engine stalls, repeat the
above operation. When the engine is warm,
choking may not be necessary.
* Cold starting. In the spring and fall when the
morning temperatures are cool it may be difficult
to start the machine due to the parastatic load
from the hydraulic drive. To relieve this load, pull
out and up on the de-clutch chain located on the
right side of the machine behind the tire. This will
allow you to start the engine easily. When the
engine is warmed up, slowly release the de-
clutch chain to engage the hydraulic system.
4. Engage the cutter blades by pulling the blade clutch
switch into the ON position. Push the switch to the
OFF position to disengage the cutter blades.
-NOTE-
When PTO is engaged or (possibly) disengaged,
a squealing sound from the underside of the
machine is normal. It is caused by the electric
clutch plates meshing as the mower comes up to
speed. For best equipment life, engage the
clutch with the engine at 3/4 throttle, not under
full load.
WARNING:
If you are not familiar with the operation of the
hydrostatic drive and zero turn feature, practice
turning and maneuvering with the hand controls
before engaging the blades.
5. Release the parking brake. Move the speed adjust-
ment lever to the desired mowing speed.
Top speed is suggested only for transport!
6. While squeezing the steering brake levers with both
hands, release both neutral latches.
7. When the steering brake levers are released, the
machine will travel straight. To make a right turn,
squeeze the RH lever. To turn left, squeeze the LH
lever.
8. TO STOP, squeeze both levers, lock the neutral
latches, and move the speed adjustment lever to
neutral.
9. To move the machine in reverse, squeeze up on both
steering control levers.
