7. Before attempting to start the engine, shift the
transmission into neutral, move the blade engage-
ment switch to the OFF position, and move the
neutral latches to neutral.
WHILE OPERATING
1. Start the engine when the neutral latches are in the
neutral lock position, the cutter blades are disen-
gaged, and the transmission is in neutral.
2. Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are ha ard-
ous and could possibly be deadly.
3. Using the machine demands attention. To
prevent loss of control:
A. Mow only in daylight or when there is good
artificial light.
B. Watch for holes or other hidden ha ards.
C. Do not drive close to a drop-off, ditch, creek
bank, or other ha ard.
D. Reduce speed when making sharp turns and
when turning on hillsides.
E. Always be sure of your footing. Keep a firm
hold on the handles and walk---never run.
F. Do not operate where conditions are slippery.
4. The discharge chute must always be installed and
in the down position on the side discharge cutter
deck except when the Scag optional grass catcher
or mulching plate are properly installed. If the
discharge area should plug, shut the engine off
and wait for all movement to stop before remov-
ing the obstruction.
5. Disengage the blades and wait for them to stop
before crossing gravel drives, walks or roads.
6. Shut the engine off and wait until the blades come
to a complete stop before removing the grass
catcher container.
7. Never raise the cutter deck while the blades are
rotating.
8. Always park the mower and/or start the engine on
a level surface.

5
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 ha ardous.
MAINTENANCEAND 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 if it has
one, drain the gasoline from the fuel tank and the
oil from the crankcase.
3. To reduce potential fire ha ard, keep the engine
free of excessive grease, grass, leaves and
accumulations 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 mainte-
nance adjustment, keep hands, feet, clothing 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 authori ed 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.

9. If the cutting blades should strike a solid object
or the equipment should start to vibrate abnor-
mally, stop the engine, disconnect the spark plug
wire, and check immediately for the cause.
Vibration is generally a warning 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.
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.
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 a burn.
12. Before leaving the operators position or leaving
the mower unattended, shift the transmission into
neutral, place the neutral latches in the neutral
lock position, and move the blade engagement
switch to OFF. Shut the engine OFF and remove
the key.
13. Do not pass or stand on the grass discharge side
of any mower with the engine running. Stop
operation when another person approaches.
WARNING:

9. Always store gasoline in a safety-approved, red
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 ORAPPROXIMATELY 10
HOURS)

TRANSMISSION DRIVE BELT
The transmission drive belt on the SWU belt drive machine
has a spring-loaded idler system and needs no adjustment.
If you find that the transmission slips, see your local Scag
Servicing Dealer for service.
DRIVE CONTROL ADJUSTMENTS
1. Adjust the steering control rods so that there is
approximately 3/4" clearance from the bottom of
the rod to the bottom of the neutral latch slot when
in the drive position. (See Figure 1)
Figure 1. Steering Control Rod Adjustment
2. Adjust the steering brake rods so that the brakes do
not apply until the steering levers are pulled tight to
the handles. When the steering levers are locked in
the neutral position the machine should move freely.
"ADJUST-A-GRIP SETTINGS"
"Adjust-A-Grip," with three settings, allows hand force
adjustment in the field, with no tools required. To
operate the "Adjust-A-Grip", pull back on the handle
and move the lever up or down depending on the
amount of belt force needed (See Figure 2, page 8).
-NOTE-
When the PTO is engaged or (possibly) disen-
gaged, a sq ealing so nd from the nderside of
the machine is normal. It is ca sed by the
electric cl tch plates meshing as the c tter
blades come p to speed. For best eq ipment
life, engage the cl tch with the engine at 1/2
throttle, not nder f ll 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 s ggested only for transport!
6. While squee ing 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, squee e the RH lever. To turn left, squee e
the LH lever.
8. TO STOP, squee e both levers, lock the neutral
latches, and shift the transmission into neutral.
CUTTER DECK BELT ADJUSTMENTS
Due to a spring-loaded idler system, there is no adjust-
ment necessary for the cutter deck belts. The 36" cutter
deck has one spring-loaded idler. The 48" cutter deck
has two spring loaded idlers.
