nOTE:

If the battery is put into

service after the date shown
on top/side of battery, charge
the battery as instructed in the
Product Care section prior to
operating the mower.

Fuel & Oil

1. The fuel tank has a capacity of five gallons. Remove the fuel cap by turning it counter-

clockwise. Use only clean, fresh (no more than 30 days old), unleaded gasoline. Do
not overfill the fuel tank. Fill the tank to the bottom of the filler neck, allowing some
space in the tank for fuel expansion.

WARNING: Use extreme care when handling gasoline. Gasoline is extremely

flammable and the vapors are explosive. Never fuel the machine indoors or

while the engine is hot or running. Extinguish cigarettes, cigars, pipes, and

other sources of ignition.

2. Your mower is shipped with oil in the engine. However, you MUST check the oil level

before operating. Refer to the Engine Operator’s Manual for oil checking procedures.

WARNING: Always check the engine oil level before each use as instructed

in the Engine Operator’s Manual. Add oil as necessary. Failure to do so may

result in serious damage to your engine.

Tire Pressure

The recommended operating rear tire pressure is 12 psi. The caster wheels are semi-
pneumatic and do not require air pressure. Check the tire pressure periodically and
maintain equal pressure in both rear tires at all times.

iMPORTAnT!

Refer to the tire sidewall for exact tire manufacturer’s recommended or

maximum psi. Do not overinflate. Uneven tire pressure could cause the cutting deck to
mow unevenly.

USE THE SLOPE GAUGE ON THE BACK COVER AS SHOWN TO DETERMINE IF A SLOPE IS TOO

STEEP FOR SAFE OPERATION!

To check the slope, proceed as follows:

1.  Open manual to the back cover and fold along the dashed line.
2.  Locate a vertical object on or behind the slope (e.g. a pole, building, fence, tree, etc.).
3.  Align either side of the slope gauge with the object.
4.  Adjust gauge up or down until the left corner touches the slope.
5.  If there is a gap below the gauge, the slope is too steep for safe operation.
