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.
To Reinstall Blade
•
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.
Deck Maintenance
•
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.
Engine Maintenance
•
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.
