LIMITED WARRANTY-COMMERCIAL EQUIPMENT
This warranty extends to the original retail purchaser
only and commences on the date of original retail pur¬
chase.
Any part of the Scag commercial mower manufactured by
Scag and found in the reasonable judgment of Scag to be
defective in material or workmanship, will be repaired or
replaced by an Authorized Scag Service Dealer without
charge for parts and labor.
The Scag mower including any defective part must be re¬
turned to an Authorized Scag Service Dealer within the
warranty period. The expense of delivering the mower to
the dealer for warranty work and the expense of returning
it back to the owner after repair or replacement will be
paid for by the owner. Scag’s responsibility in respect to
claims is limited to making the required repairs or
replacements, and no claim of breach of warranty shall
be cause for cancellation or rescission of the contract of
sale of any Scag mower. Proof of purchase will be required
by the dealer to substantiate any warranty claim. All
warranty work must be performed by an Authorized Scag
Service Dealer.
This warranty is limited to one year from the date of
original retail purchase for any Scag mower that is used
for commercial purposes, or any other income-produc¬
ing purpose (90 days for rental use).
This warranty does not cover any mower that has been
subject to misuse, neglect, negligence, or accident, or that
has been operated in any way contrary to the operating
instructions as specified in the Technical Manual. The
warranty does not apply to any damage to the mower that
is the result of improper maintenance, or to any mower
or parts that have not been assembled or installed as
specified in the Technical Manual.
The warranty does not cover any mower that has been al¬
tered or modified so as to adversely affect the product's
operation, performance or durability or that has been al¬
tered or modified so as to change the intended use of the
product. In addition, the warranty does not extend to
repairs made necessary by normal wear, or by the use of
parts or accessories which, in the reasonable judgment of
Scag, are either incompatible with the Scag mower or ad¬
versely affect its operation, performance or durability.
This warranty does not cover engines, electric starters,
batteries, belts and tires which are warranted separately
by their manufacturer and for a different period of time.
Scag Power Equipment reserves the right to change or
improve the design of any mower without assuming any
obligation to modify any mower previously manufactured.
All other implied warranties are limited in duration to the
one (1) year warranty period or ninety (90) days for
mowers used for rental purpose. Accordingly, any such
implied warranties including merchantability, fitness for
a particular purpose, or otherwise, are disclaimed in their
entirety after the expiration of the appropriate one year
or ninety day warranty period. Scag's obligation under
this warranty is strictly and exclusively limited to the
repair or replacement of defective parts and Scag does
not assume or authorize anyone to assume for them any
other obligation. Some states do not allow limitations on
how long an implied warranty lasts, so the above limita¬
tion may not apply to you.
Scag assumes no responsibility for incidental, conse¬
quential or other damages including, but not limited to,
expense for gasoline, expense of delivering the mower to
an Authorized Scag Service Dealer and expense of return¬
ing it back to the owner, mechanic’s travel time,

during the lime warranty repairs are being performed,
travel, loss or damage to personal property, loss of
revenue, loss of use of the mower, loss of time or
inconvenience. Some states do not allow the exclusion or
limitation of incidental or consequential damages. So the
above limitation or exclusion may not apply to you.
This warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.

SAFETY INSTRUCTIONS
Your mower is only as safe as the operator! As with any
type of power equipment, carelessness or error on the part
of the operator may result in serious bodily injury. In
addition, improper maintenance of the machine can also
result in injury. To reduce the potential for injury, please
read and follow these instructions on safe operatioh and
be certain that anyone using this mower fully understands
and complies with the following instructions.
Before Operating
1. Read and understand the contents of this Technical
Manual before operating the machine. Become familiar
with all controls and know how to stop quickly. A free
replacement manual is available by sending complete
Model and Serial Number to:
Scag Power Equipment, Inc.
W226 N900 Eastmound Drive
Waukesha. Wi 53186
2. Do not allow children to operate the machine. Do not
allow adults to operate the machine without proper
instruction.
3. Before attempting to start engine, shift transmission
into neutral, move blade clutch lever into STOP position
and move neutral latch to NEUTRAL LOCK.
4. Remove all debris or other objects that might be
picked up and thrown by the cutter blades. Keep all
bystanders away from the mowing area.
5. Keep all shields, safety devices, and decals in place.
If a shield, safety device or decal is defective or damaged,
repair or replace it before operation is commenced. Also,
tighten all loose nuts, bolts and screws to assure machine
is in safe operating condition.
6. Do not operate machine while wearing sandals, tennis
shoes, sneakers or shorts. Also, do not wear loose fitting
clothing which could get caught in moving parts. Always
wear long pants and substantial shoes. Wearing safety
glasses and safety shoes is advisable and required by some
local ordinances and insurance regulations.
7. Fill fuel tank with gasoline before starting the engine.
Avoid spilling gasoline. Since gasoline is flammable, handle
it carefully.
A. Use an approved gasoline container.
B. Do not fill tank while engine is hot or running.
C. Do not smoke while handling gasoline.
D. Fill fuel tank outdoors and up to about one inch
(25 mm) below the bottom of the filler neck.
E. Wipe up any spilled gasoline.
While Operating
8. Start engine when neutral latches are in neutral lock
position, cutter blades are disengaged, and transmission
is in neutral.
9. Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
10. 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 hazards.
C. Do not drive close to a drop-off, ditch, creek or other
hazard.
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 handle and walk—never run.
F. Do not operate where conditions are slippery.
11. The discharge chute must always be installed and in
the down position on the side discharge cutting unit
except when optional grass catcher is completely in¬
stalled. If the cutting unit discharge ever plugs, shut
engine off and wait for all movement to stop before
removing obstruction.
12. Disengage the blades and wait for them to stop before
crossing gravel drives, walks or roads.
13. Shut the engine off and wait until the blades come
to a complete stop before removing the grass catcher
container.
14. Never raise the cutting unit while the blades are ro¬
tating.
15. If the cutting blades should strike a solid 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 a
warning of trouble. Check the cutting unit and traction
unit for damaged or defective parts. Repair any damage
before starting the engine and operating the cutter unit.
Be sure blades are in good condition and blade bolts are
tight.
16. Always park the mower and/or start the engine on a
level surface. If this is not possible, block the wheels to
prevent the mower from moving when you are not in the
operator’s position.

17. Cut grass slopes carefully. Do not start, stop, or turn
suddenly. Mow across the face of slopes; never up or down.
Do not mow excessively steep slopes.
18. Do not touch engine or muffler while engine is running
or soon after it is stopped. These areas could be hot
enough to cause a burn.
19. Before leaving the operator’s position or leaving
mower unattended, shift transmission into NEUTRAL, place
neutral latches in NEUTRAL LOCK position, move cutter
blade engagement lever to STOP and shut OFF engine.
20. Do not pass or stand on the grass discharge side of
any mower with the engine running. Stop operation when
another person approaches.
Maintenance and Storage
21. Disconnect high tension wire from spark plug to
prevent accidental starting of the engine when servicing,
adjusting or storing the machine.
22. If tractor and mower must be tipped to perform main¬
tenance or adjustment, drain gasoline from fuel tank and
oil from crankcase.
23. To reduce potential fire hazard, keep the engine free
of excessive grease, grass, leaves and accumulations of
dirt.

keeping nuts, bolts, and screws tight. Check the blade
mounting bolts and nuts frequently to be sure they are

authorized dealer check maximum engine speed with a
tachometer.
27. Engine must be shut off before checking oil or adding
oil to the crankcase.
28. Allow engine to cool before storing mower in any en¬
closure such as a garage or storage shed. Make sure the
mower fuel tank is empty if machine is to be stored in
excess of 30 days. Do not store mower near any open flame
or where gasoline fumes may be ignited by a spark.
29. Always store gasoline in a safety-approved, red metal
container.
