If the cutting blades should strike asolid object or
the equipment should start to vibrate abnormally,
stop the engine, disconnect the spark plug wire, and
check immediately for the cause. Vibration is
generally awarning of trouble. Check the machine
for damaged or defective parts. Repair any damage
before starting the engine or operating the cutter
deck. Be sure the blades are in good condition and
the blade bolts are tight.
14. Use only Scag approved riding attachments.
Scag Approved Riding Attachments:
RS-2
RS-ZT
Using unapproved attachments, (especially "stand-
up" riding attachments) may be hazardous.
MAINTENANCE AND STORAGE
10. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tipping or loss
of control. Be especially cautious when changing
directions on slopes.
,WARNING:
DO NOT operate on steep slopes. To check a
slope, attempt to back up it (with the cutter deck
down), if the machine can back up the slope
without the wheels slipping, reduce speed and use
extreme caution. ALWAYS FOLLOW OSHA
APPROVED OPERATION.
11. Do not touch the engine or muffler while the engine
is running or soon after it is stopped. These areas
could be hot enough to cause aburn.
12. Before leaving the operator's position or leaving the

Disconnect the spark plug wire from the spark
plug to prevent accidental starting of the engine
when servicing, adjusting or storing the machine.
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.
To reduce potential fire hazard, keep the engine
free of excessive grease, grass, leaves and accu-
mulations of dirt.
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.
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.
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.
The engine must be shut off before checking the
oil or adding oil to the crankcase.
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.

CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, itis difficult
to suggest a cutter deck setting that will work for every
lawn. There are two adjustments that can be made on
these decks, pitch andheight.
PITCH is the angle of the blades (comparing front to
rear). A 1/4" downward pitch (front of deck down) is
recommended for best cutting performance.
HEIGHT is the nominal distance the blade is offofthe
ground. This measurement is made with the blades
pointed side to side and distance is measured between
cuttingtip andground. (Also seeBladeHeightAdjust-
merit, nextpage)
Changes to the cutting height can be achieved by reposi-
tioning the cutter deck (This adjustment will also effect
the pitch of the deck). There are three available posi-
tions (see figure 5).
LOW CUT (1 3/4" to 3")
MID RANGE
1/2" to 3 3/4")
HIGH CUT
(3 1/4" to 4 1/2")
