engine damage which may not be covered under
warranty .
• Do not use gasoline containing methanol.
• Do not store fuel either in the fuel tank or fuel
containers over the winter unless you use a fuel
stabilizer .
• Do not add oil to gasoline.
Using Stabilizer/Conditioner
Use fuel stabilizer/conditioner in the machine to keep
the fuel fresh longer when used as directed by the
fuel-stabilizer manufacturer .
Important: Do not use fuel additives containing
methanol or ethanol.
Add the amount of fuel stabilizer/conditioner to fresh
fuel as directed by the fuel-stabilizer manufacturer .
Filling the Fuel T ank
1. Park the machine on a level surface, disengage
the PT O, move the motion-control levers to the
N EUTRAL -L OCK position, and engage the parking
brake.
2. Shut of f the engine, remove the key , and wait
for all moving parts to stop before leaving the
operating position.
3. Clean around the fuel-tank cap and remove the
cap.
4. Fill the fuel tank to the bottom of the ller neck.
Note: Do not ll the fuel tank completely full.
The empty space in the tank allows the fuel to

Performing Daily
Maintenance
Before starting the machine each day , perform the
Each Use/Daily procedures listed in Maintenance
( page 27 ) .
Breaking in a New Machine
New engines take time to develop full power . Mower
decks and drive systems have higher friction when
new , placing additional load on the engine. Allow
40 to 50 hours of break-in time for new machines to
develop full power and best performance.
Using the Safety-Interlock
System
W ARNING
If safety-interlock switches are disconnected
or damaged, the machine could operate
unexpectedly , causing personal injury .
• Do not tamper with the interlock switches.
• Check the operation of the interlock
switches daily , and replace any damaged
switches before operating the machine.
Understanding the
Safety-Interlock System
The safety-interlock system is designed to prevent
PT O from engaging unless you do 1 of the following:
• Move either motion-control lever to the center ,
unlocked position.
• Press the O N position on the PT O switch.
The safety-interlock system is designed to stop
the blades/attachment if you move or release
both motion-control levers into the N EUTRAL - LOCK
position.
The hour meter has symbols to notify the user
when each interlock component is in the correct
position. When the component is in the correct
position, a triangle lights up in the corresponding
square ( Figure 7 ).
