WARNING

DO NOT attempt any maintenance, adjustments or service

with engine and blade running. STOP engine and blade.

Disconnect spark plug wire and secure away from spark

plug. Engine and components are HOT. Avoid serious

burns, allow sufficient time for all components to cool.

Belt Service

On self-propelled mowers, the engine belt transmits power

from the engine to the transmission that powers the rear

wheels. Should the belt become worn, it could cause

slippage, which would impair mower performance. The

condition of the engine belt should be checked after every

25 hours of mower operation.
