CAUTION: Be sure to disconnect and ground the spark plug wire before working on the cutting blade to prevent accidental
engine starting. Protect hands by using heavy gloves or a rag to grasp the cutting blades.
Tip mower as specified in separate engine manual. Remove the hex bolt and washer, which holds the blade and blade adapter to
the engine crankshaft. Remove the blade and adapter from the crankshaft.
WARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when
necessary. For best results your blade should be sharp. Slightly worn blades may be re-sharpened with care. After removing the
blade, it may be ground or filed, so that the cutting edge is as close to the original bevel as possible. It is extremely important that
each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. Improper blade balance will result in
excessive vibration causing damage to the engine and mower. Be sure to carefully balance blade after sharpening. The blade
can be tested for balance by balancing it on a round shaft screwdriver. Remove metal from the heavy side, until it balances
evenly.
Before reassembling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the
blade adapter with light oil. Install the blade adapter on the crankshaft. Refer Fig.15. Place the blade with the part number facing
away from the adapter. Align the washer over the blade and insert the hex bolt. Tighten the hex bolt to the torque listed below:

Refer to the separate engine manual for engine maintenance instructions.
Maintain engine oil as instructed in the separate engine manual packed with your unit.
Read and follow the engine instructions carefully.
Service the air filter as per the separate engine manual. Clean every few hours under extremely dusty conditions. Poor engine
performance and flooding usually indicates that the air filter requires attention. To service the air filter, refer to the separate
engine manual packed with your mower. The spark plug should be cleaned and the gap reset annually. Spark plug replacement
is recommended at the start of each mowing season. Check the engine manual for the correct plug type and gap specifications.
Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to permit proper air
circulation, which is essential to engine performance. Be certain to remove all grass, dirt and combustible debris from the muffler
