WARNING:  Periodically inspect the blade
adapter for cracks, especially if you strike a
foreign object. Replace when necessary.

•

When sharpening the blade, follow the original 
angle of grind as a guide. It is extremely important 
that each cutting edge receives an equal amount of 
grinding to prevent an unbalanced blade. An 
unbalanced blade will cause excessive vibration 
when rotating at high speeds, may cause damage 
to the mower and could break, causing personal 
injury.

•

The blade can be tested by balancing it on a round 
shaft screwdriver. Remove metal from the heavy 
side until it balances evenly. It is recommended that 
the blade always be removed from the adapter for 
the best test of balance.

•

Before reinstalling the blade and the blade adapter 
to the unit, lubricate the engine crankshaft and the 
inner surface of the blade adapter with light oil (or 
engine oil). Lubricating the bolt holes, bolts and 
inner surface of the nuts is also recommended.

•

Be sure to install the blade with the side of the 
blade marked “Bottom” (or with part number) facing 
the ground when the mower is in the operating 
position.

•

Be certain the blade is aligned with and seated onto 
the blade adapter flanges.

•

Place blade bell support on blade. Make sure the 
notches on the blade bell support are aligned with 
the small hole in the blade.

•

Replace hex bolt.

•

Tighten to torque: 450 in. lbs. min., 600 in. lbs. max.

•

To ensure safe operation of mower, check all nuts 
and bolts periodically for correct torque.

•

The underside of the mower deck should be 
cleaned after each use to prevent a buildup of 
grass clippings, leaves, dirt or other matter. If this 
debris is allowed to accumulate, it will invite rust 
and corrosion, and may prevent proper mulching.

•

The deck may be cleaned by tilting the mower and 
scraping clean with a suitable tool (make certain the 
spark plug wire is disconnected). Do not use high 
pressure cleaners or water. 

•

We do not recommend the use of pressure 
washers or garden hose to clean your unit. They 
may cause damage to electric components, 
spindles, pulleys, bearings or the engine. The use 
of water will result in shortened life and reduce 
serviceability.

•

Refer to the separate engine manual for all engine 
maintenance instructions.

•

Maintain ENGINE OIL as instructed in the engine 
manual.

•

Service AIR CLEANER every 25 hours under 
normal conditions. Clean every few hours under 
extremely dusty conditions. Poor engine 
performance and flooding usually indicates that the 
air cleaner should be serviced. To service the air 
cleaner, refer to the engine manual.

•

The SPARK PLUG should be cleaned and the gap 
reset once a season. Spark plug replacement is 
recommended at the start of each mowing season; 
check engine manual for correct plug type and gap 
specifications. 

•

CLEAN the engine regularly with a cloth or brush. 
Keep the cooling system (blower housing area) 
cleaned to permit proper air circulation which is 
essential to engine performance and life. Be certain 
to remove all grass, dirt and combustible debris 
from muffler area.
