13. Do not pass or stand on the grass discharge side
of any mower with the engine running. Stop
operation when another person approaches.
14. Use only Scag approved riding attachments.
Scag Approved Riding Attachments:
RS-2
RS-ZT
Usingunapprovedattachments,(especially"stand-
up" riding attachments) may be hazardous.
MAINTENANCE AND STORAGE
1. Disconnect the spark plug wire from the spark
plug to prevent accidental starting of the engine
when servicing, adjusting or storing the machine.
2. If the mower must be tipped to perform mainte-
nance or adjustment, remove the battery, drain
the gasoline from the fuel tank and the oil from
the crankcase.
3. To reduce potential fire hazard, keep the engine
free of excessive grease, grass, leaves and accu-
mulations of dirt.
4. Be sure the machine is in safe operating condition
by keeping nuts, bolts, and screws tight. Check
the blade mounting bolts and nuts frequently to
be sure they are tightened.
5. If the engine must be running to perform a
maintenance adjustment, keep hands, feet, cloth-
ing and other parts of the body away from the
cutter deck blades and other moving parts.
6. Do not overspeed the engine by changing gover-
nor settings. To be sure of safety and accuracy,
have an authorized dealer check maximum engine
speed with a tachometer.
7. The engine must be shut off before checking the
oil or adding oil to the crankcase.
8. Allow the engine to cool before storing the
mower in any enclosure such as a garage or
storage shed. Make sure the fuel tank is empty if
the machine is to be stored in excess of 30 days.
Do not store the mower near any open flame or
where gasoline fumes may be ignited by a spark.

container.
10. Be careful when servicing the battery as it con-
tains acid, which is corrosive and could cause
burns to skin and clothing.
11. Batteries release explosive gases when being
charged or discharged. Keep batteries away
from any source of sparks and/or flame.
INITIAL RUN-IN PROCEDURES
(FIRST DAY OF USE OR APPROXI-
MATELY 10 HOURS)
1. Check the belts for proper tension at 2, 4 and 8
hours. Adjust as needed.
2. Check the steering control rods for neutral
adjustment. (See Adjustments, page 6)
3. Checkthetiresforproperpressure.
CasterWheels 25psi.
DriveWheels 15psi.
4. Checkforloosehardware. Tightenasneeded.
5. Checkthesafetyswitchesforproperadjustment:
* Theenginewillcrank,butnotstartifthe

6. Applylubricantto allthegrease fittings.
Lubricant was applied at the factory. This is
just a precautionary check to make sure that
allthefittingshavebeenlubricated.
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.
* Fill the fuel tank with clean, fresh, lead-free
gasoline.
* Open the fuel valve on the bottom of the
fuel tank.
MOWER OPERATION
-NOTE-
Use gasoline with an octane rating no less than
87.
* The transmission must be in NEUTRAL.
* The blade clutch switch must be in the OFF
position.
* The operator's presence levers must be
released.
* The neutral latches must be in the neutral
lock position.
* The key switch 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.
4. Engagethecutterbladesbypullingthebladeclutch

PULL UP TO ENGAGE
PUSH DOWN TO DISENGAGE

-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 cutter blades come
up to speed. For best equipment life, engage the
clutch with the engine at 1/2 throttle, not under
full load.
To avoid serious bodily injury and damage to the
transmission, the machine must be at a full stop
before shifting between gears or shifting between
forward and reverse.
5. Shift the transmission into gear for the desired
mowing speed.
-NOTE-
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
machinewill travelstraight. Tomakearightturn,
squeezetheRHlever. Toturnleft,squeezetheLH
lever.
8. TO STOP, squeeze both levers, lock the neutral
latches, and shift the transmission into neutral.
