Servicing the Fuses
The electrical system is protected by fuses. It requires no maintenance; however, if a fuse
blows, check the component/circuit for a malfunction or short.
1. Park the machine on a level surface, disengage the blade-control switch, and move the
motion-control levers outward to the P
2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving
the operating position.
3. Replace the blown fuse with a new fuse.

Checking the Tire Pressure
Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can
cause an uneven cut. Check the pressure at the valve stem when the tires are cold to get
the most accurate pressure reading.
1. Inflate the front caster wheel tires to 206 kPa
(30 psi) or the pressure indicated on the
sidewall, whichever is lower.
2. Inflate the rear drive-wheel tires to 90 kPa (13
psi).
