UNPACKING

• Remove the bolts securing the corner and
side braces to the frame bottom, then lift the
braces to remove.
• Cut the nylon straps securing the front and
rear wheel axles to the frame.
• Remove boxes containing loose parts,
assembly hardware, and documentation.
• Remove and set aside all accessible
packaging and wrap from unit and parts. Do
not discard the packing material until you
have carefully inspected and satisfactorily
operated the product.
WARNING
If any parts on the Loose Parts List are al-
ready assembled to your product when you
unpack it, verify the part is assembled correct-
ly, is properly tightened, and is torqued cor-
rectly (where applicable) before proceeding to
the next assembly step. Use of a product that
may have been improperly assembled could
result in serious personal injury.
• Inspect the product carefully to make sure
no breakage or damage occurred during
shipping.
NOTE: Mower should be assembled while po-
sitioned on the frame bottom. Once assembly
is complete, raise the cutting deck to its highest
position, then position a ramp next to the frame
bottom and slowly and carefully drive mower off
frame.
WARNING
Use care when driving the mower off of the
frame and press the brake pedal as needed
to control the speed. The mower will freely roll
if it is moved on an inclined surface without
pressing the brake pedal or setting the parking
brake. Failure to follow these instructions can
result in loss of control and result in death, se-
rious personal injury, or property damage.
WARNING
If no ramp is available, slowly and carefully
drive the mower off the frame in reverse while
looking down and behind. Driving the mower
off the frame in the forward direction without a
ramp can cause damage to the mower’s cut-
ting deck.

FINAL PREPARATION

CHECK TIRE PRESSURE
Check the air pressure in all tires before use.
Improper air pressure will affect handling,
steering response, traction, tire life, level cutting,
and operator comfort. Be sure tires are inflated
to the pressure shown below.
NOTE
Tire pressure should only be measured or
adjusted when tires are cold.
Front caster wheels 37 psi
Drive wheels 8 psi
WARNING
Check the tire pressure carefully while inflating.
Too much air in the tire could cause the tire to
burst, causing serious personal injury.
CHECK THE BATTERY CAPACITY
To verify mower batteries are fully charged,
check the battery level indicator. See battery
manuals for details.
WARNING
To avoid accidental starting or movement of
the mower that could result in serious personal
injury, always remove the start key and set
the parking brake when leaving the mower
unattended.
NOTE
Always charge batteries after each use.
TEST THE SAFETY INTERLOCK SYSTEM
This mower features a Safety Interlock System
to protect the operator by shutting off the blades
if the operator leaves the seat with the blades
running. Test the system to be sure it is working
correctly.
TO TEST:
• Make sure direction control switch is in
PARK position and PTO switch is down.
• Make sure the operator is on the seat.
Install start key and turn to ON ( ) position.
• Raise the PTO switch to activate blades.
• Briey lift off the seat, but do not get off the
mower.
The blades should shut off within 5 seconds. If
they don’t, verify you connected the seat plug
to the machine. If the plug is connected but the
system still doesn’t function, contact customer
service. Do not operate the mower until the
safety interlock system has been repaired.
