WHILE OPERATING
8.
Start engine when neutral latches are in neutral lock
position, cutter blades are disengaged, and transmis-
sion is in neutral.
Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous
and could possibly be deadly.
. Using the machine demands attention. To prevent loss
of control:
A. Mow only in daylight or when there is good artificial
light.
Watch for holes or other hidden hazards.
Do not drive close to a drop-off, ditch or creek bank
or other hazard.
Reduce speed when making sharp turns and when
turning on hillsides.
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.
m D OW
. Thedischarge chute must always be installed andinthe
down position on the side discharge cutting unit except
when optional grass catcher or mulching plate are com-
pletely installed. if the cutting unit discharge should
plug, shut engine off and wait for all movement to stop
before removing obstruction.
. Disengage the blades and wait for them to stop before
crossing gravel drives, walks or roads.
. Shut the engine off and wait until the blades come to a
complete stop before removing the grass catcher
container.
. Never raise the cutting unit while the blades are rotat-
ing.
. 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.
. 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 inthe
operator’s position.
. 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.

ASSEMBLY INSTRUCTIONS
ELECTRIC START UNITS ONLY!
Before proceeding with assembly, prep the battery. Fill
each cell with electrolyte until the top of the plates are
covered. Charge the battery at 3 to 4 amps for 4 hours (this
insures a good initial charge), check and add electrolyte as
needed to bring the fluid level to the bottom of the split ring.
Then wash and dry off the battery.
NOTE: Once the above fill and charge procedure has been
completed only distilled water should be added to the
battery cells.
Set the battery into the support, connect the positive cable
to the positive post, then connect the negative cable to the
negative post. Put the battery cover in place (at the back of
the battery), and clamp the battery into place (finger tight)
using the carriage bolts and wing nuts. DO NOT OVER
TIGHTEN.
WARNING: Severe chemical burns can result from im-
proper handling of battery electrolyte. Use proper eye, skin
and clothing protection to prevent contact with eyes, skin
and clothing.
External contact: Flush with water.
Internal contact: Drink large quantities of water, followed by
milk of magnesia, beaten egg or vegetable oil.
CALL A PHYSICIAN IMMEDIATELY!
IMPORTANT - In case of internal contact DO NOT give
fluids that would induce vomiting.
Eye contact: Flush with water for at least 15 minutes and
GET MEDICAL ATTENTION IMMEDIATELY!

ADJUSTMENTS
GENERAL ADJUSTMENTS
Check that all belts clear their guides by 1/8" to 1/4".
‚2. Adjust tension of blade drive belt by rotating turnbuckle
so that about 10 pounds pull sideways deflects belt
about a 1/2". DO NOT OVERTIGHTEN. Only a moder-
ate force should be required on the engagement lever.
3. Check tension of transmission drive belt (under engine
deck). A ten pound pull sideways should deflect belt
about 3/16". Slide idler pulley if required to adjust.
4. Thetension ofthe two Twin Power Wheel Drive belts is
self-adjusting. However, for adequate declutching,
adjust length of steering control rods on each side of
handle until about a 1/4" gap is provided between rod
and bottom of neutral latch slot, when neutral latch is in
drive position.
5. Adjust brake rods so that brakes will lock wheels while
pulling machine rearward with steering levers fully
squeezed. Check that machine rolls freely when neu-
tral latches are in neutral lock position.
CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, it is difficult to
suggest a setting that will work for every lawn. There are two
adjustments that can be made on these decks, pitch and
height.
PITCH is the angle of the blades (comparing front to rear).
A positive pitchis when the front (leading) edge of the cutting
plane is lowerthan the rear (trailing) edge, leve! pitchis when
both front and rear are the same height, a negative pitch is
when the leading edge is higher than the rear edge. We
suggest that a postive pitch be used when cutting grass. The
front of the deck should be 1/4" to 1/2” lower than the rear
of the deck.
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.
TAPERED BEARING SPINDLE ASSEMBLY
Adjusting the blade height can be done by moving any
number of the four smaller 1/4" spacers on the blade mount-
ing bolts to the top of the spindle shaft or below the spindle
shaft. (All blades should be positioned equally). The tapered
bearing spindle has a large 1/4" spacer that is installed
directly below the spindle housing and is secured to the
spindle with two roll pins. The blade can be adjusted all the
way up to the spindle assembly if all the smaller 1/4" spacers
are removed and installed above the pulley. The larger 1/4°
spacer can then be removed along with the roll pins. (Do not
install the larger 1/4" spacer above the pulley, store it in a
convenient location away fromthe machine). When any 1/4"
spacers are installed above the blades the larger 1/4" spacer
must be installed directly below the spindle housing. lf a
smaller 1/4" spacer is installed directly below the spindle
housing and contacts the retaining ring this will cause a
spindle failure and not be warrantable. For best cut and
discharge, a minimum of three spacers should be installed
between the blade and spindle. (see figure 10)

ADJUSTMENTS CONT'D
Additional range to the cutting height can be achieved by
repositioning the cutter deck in relationship to the engine
deck (This adjustment can also effect the pitch of the deck).
There are 3 positions (see figure 6), suggested mounting is
the middle holes. For cutting lower, mount the deck in the
top holes. To cut higher, mountthe deck inthe bottom holes.
Remember to check the cutter deck belt alignment. Shim-
ming or attaching the idler mounting bracket from under-
neath may be necessary to maintain belt life.
Caster spacers also can be repositioned to change cutting
heights and to change the pitch of the deck (see figure 11).

A WARNING
LIMITED WARRANTY-COMMERCIAL EQUIPMENT
Any part of the Scag commercial mower manufactured by Scag and found, in:the reasonable judgment of Scag, to be
defective in materials or workmanship, will be repaired or replaced by án 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:
* Frame, deck and structural components including oil reservoirs - 1 year
* Wear items including drive belts, blades, hoses and tires are warranted for 90 days
* Engines and electric starters are covered by the manufacturer's warranty period.
* Drive system components are covered by the manufacturer's warranty period.
(Excluding fittings, hoses, cooling system, oil reservoir, drive belts.) Drive systems
are warranted by Scag Power Equipment in conjunction with the component manufacturer.
* Batteries are covered for 1 year. |
* Any Scag product used for rental purposes is covered for 90 days.
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 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
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 incon-
venience. 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.
