FUEL IN CONTAINERS SPECIFICALLY DESIGNED FOR THAT PURPOSE. ADD FUEL OUTDOORS ONLY
AND IF THE FUEL IS SPILLED, DO NOT START THE ENGINE. MANUALLY PUSH THE MOWER AWAY FROM
THE SPILL AND IMMEDIATELY WIPE UP.
Refer to the Engine Owner’s Manual for the type of fuel to use.
A fuel shut off valve is located on the bottom of the fuel tank. (Refer to Figure 2, page 10). It is recommended
that the fuel be shut off when transporting between job sites and when storing the mower for extended periods

The recommended tire pressure for the two drive wheels is 28 P.S.I. The recommended tire pressure for the
two front wheels is 22 P.S.I. Incorrect tire pressure may cause the mower to pull to one side and/or an uneven
cut. Always use caution when filling the tire and never exceed the recommended tire pressure.
Blades
DANGER: BEFORE WORKING ON THE BLADES, MAKE SURE THE ENGINE IS OFF, KEY REMOVED, AND
THE SPARK PLUG(S) WIRES REMOVED FROM THE SPARK PLUG (S) AND HIDDEN TO PREVENT ACCIDEN-
TAL CONTACT.
CAUTION Beware of the cutting edges on the blades. Always wear work gloves when performing blade
maintenance.
Blades should be inspected on a daily basis for nicks, bends, and or excessive wear. If the blades is worn,
cracked, bent, or damaged, replace with a new blade immediately before using the mower. Use only genuine
manufacturer’s replacement blades since substitute blades may not meet the manufacturer’s specifications
and may be dangerous.
To remove the blades, refer to page 13, section “Removing And Adjusting The Blades.”
When sharpening the blades, sharpen only the cutting edges and maintain the original angle of the blade. Do
not make the cutting edge “razor sharp” and remove the same amount from each side of the blade so that
balance is maintained.
Cleaning The Mower
It is recommended that the mower be cleaned in a daily basis. Excessive accumulation of dirt, debris, oil,
etc., causes premature wear on the components and may present a potential safety hazard.
