WHILE OPERATING

BEFORE OPERATING

1. Start the engine when the neutral latches are in

the neutral lock position, the cutter blades are

disengaged, the parking brake is on and the

speed adjustment lever is in the neutral position.

1. Know the controls and how to stop quickly.

2. Do not allow children to operate the machine.

Do not allow adults to operate the machine

without proper instruction.

2. Do not run the engine in a confined area without

adequate ventilation. Exhaust fumes are hazard-

ous and could possibly be deadly.

3. 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.

3. Using the machine demands attention. To

prevent loss of control:

4. 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

operating. Also, check all nuts, bolts and screws

for proper tightness, to assure the machine is in

safe operating condition.

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

bank, 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 handles and walk---never run.

F. Do not operate where conditions are slippery.

5. Do not operate the 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 regula-

tions.

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

removing the obstruction.

6. Fill the fuel tank with clean, fresh gasoline, with

a minimum octane rating of 87. Avoid spilling

gasoline. Gasoline is highly flammable, handle it

carefully.

5. Disengage the blades and wait for them to stop

before crossing gravel drives, walks or roads.

A. Use an approved gasoline container.

B. Do not fill the tank while the engine is hot or

running.

6. Shut the engine off and wait until the blades

come to a complete stop before removing the

grass catcher container.

C. Do not smoke while handling gasoline.

D. Fill the fuel tank outdoors and up to approxi-

mately 1" (25 mm) below the bottom of the

filler neck.

7. Never raise the cutter deck while the blades are

rotating.

E. Wipe up any spilled gasoline.

7. Before attempting to start the engine, move the

speed adjustment lever into the neutral position,

move the blade engagement switch to the OFF

position, apply the parking brake, and move the

neutral latches to neutral.

8. Always park the mower and/or start the engine

on a level surface. Apply the parking brake to

prevent the mower from moving when you are

not in the operator’s position.

Using unapproved attachments, (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.

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.

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.

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.

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 condi-

tion by keeping nuts, bolts, and screws tight.

Check the blade mounting bolts and nuts fre-

quently to be sure they are tightened.

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.

5. If the engine must be running to perform a

maintenance adjustment, keep hands, feet,

clothing and other parts of the body away from

the cutter deck blades and other moving parts.

12. Before leaving the operator’s position or leaving

the mower unattended, move the speed adjust-

ment lever into the neutral position, place the

neutral latches in the neutral lock position, apply

the parking brake, and move the blade engage-

ment switch to OFF. Shut the engine OFF and

remove the key.

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.

13. Do not pass or stand on the grass discharge side

of any mower with the engine running. Stop

operation when another person approaches.

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.

-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 1/2 throttle, not under

full load.

WARNING:

Figure 5. Caster Wheel Spacers

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.

BLADE HEIGHT ADJUSTMENT

Adjusting the blade height can be done by moving

any number of the five smaller 1/4" spacers on the

blade mounting bolts to the top of the spindle shaft

or below the spindle shaft.

HEIGHT is the nominal distance the blade is off of

the ground. This measurement is made with the

blades pointed side to side and distance is measured

between cutting tip and ground. (Also see Blade

HeightAdjustment)

-NOTE-

All blades should be positioned equally.

Changes to the cutting height can be achieved by

repositioning the cutter deck. (This adjustment will

also effect the pitch of the deck). There are three

available positions (see figure 4).

LIMITED WARRANTY-COMMERCIAL EQUIPMENT

Any part of the Scag commercial mower manufactured by Scag Power Equipment and found, in the reasonable judg-

ment of Scag, to be defective in materials or workmanship, will be repaired or replaced by an Authorized Scag Service

Dealer without charge for parts and labor. This warranty is limited to the original purchaser and is not transferable.

Proof of purchase will be required by the dealer to substantiate any warranty claims. All warranty work must be

performed by an Authorized Scag Service Dealer.

This warranty is limited to the following specified periods from the date of the original retail purchase for defects in

materials or workmanship:

* Wear items including drive belts, blades, hoses and tires are warranted for 90 days.

* Batteries are covered for 90 days.

* Frame, deck, and structural components including oil reservoir, fittings, and oil cooler

are warranted for 1 year.

* Engines and electric starters are covered by the manufacturer’s warranty period.

* Drive system components are warranted for 1 year by the component manufacturer, in

conjunction with Scag Power Equipment. (Excluding fittings, hoses, cooling system,

oil reservoir, drive belts).

* Electric clutches have a Limited Warranty for 2 years. (Parts and labor 1st year; Parts Only

2nd year)

* Cutter Spindle Assemblies 46631 have a Limited Warranty for three years (Parts and

labor 1st year; Parts only 2nd and 3rd year).

Any Scag product used for rental purposes is covered by a 90 day warranty.

The Scag mower, including any defective part must be returned 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

to the owner after repair will be paid for by the owner. Scag’s responsibility is limited to making the required repairs

and no claim of breach of warranty shall be cause for cancellation or rescission of the contract of sale of any Scag

mower.

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 Operator’s 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 Operator’s Manual and Assembly Manual. The warranty does

not cover any mower that has been altered or modified, changing performance or durability. 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 adversely affect its operation, performance or

durability.

Scag Power Equipment reserves the right to change or improve the design of any mower without assuming any obliga-

tion 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 limitation may not apply to you.

Scag assumes no responsibility for incidental, consequential 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 returning it to the

owner, mechanic’s travel time, telephone or telegram charges, rental of a like product during the time 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.
