BLADE BOLT INSTALLATION
IMPORTANT: DO NOT use components other than the original blade, blade
bushing, spring disc washer, and blade bolt supplied with the unit. Failure to use
all original components and assembled as shown will increase the risk of a blade
bolt becoming loose or weak after striking a foreign object.
POTENTIAL HAZARD

bolts can be dangerous.
WHAT CAN HAPPEN
♦ A loose or weakened blade bolt could allow a blade
rotating at a high speed to come out from under the deck,
causing serious injury or property damage.
HOW TO AVOID THE HAZARD
♦ Always use Exmark blades, blade bushings, spring disc
washers, and blade bolts and install them in the correct
positions as shown.
Check safety interlock system.
Service Interval: Daily
