Maintenance
4.
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 and life. Be certain to remove all
grass, dirt and combustible debris from muffler area.
Deck
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 scrap-
ing clean with a suitable tool (make certain the spark plug
wire is disconnected).

are tight.
2. Tip mower as specified in separate engine manual. If
it does not specify turn mower on its side making sure
that the air filter and the carburetor are up.
3. Remove the bolt and the blade bell support which
hold the blade and the blade adapter to the engine
crankshaft. See Figure 5-1.
4. Remove blade and adapter from the crankshaft.
Lubrication
1.
Lubricate the pivot points on the blade control handle
at least once a season with light oil. The blade
control must operate freely in both directions. See
Figure 5-1.
2.
If your mower is equipped with ball bearing wheels,
lubricate at least once a season with a light oil, all
other types require no lubrication. However, if the
wheels are removed for any reason, lubricate the
surface of the axle bolt and the inner surface of the
wheel with light automotive oil.
5.
The blade may be resharpened by removing it and
either grinding or filing the cutting edge keeping as
close to the original bevel as possible. Do not attempt
to sharpen the blade while it is still on the mower.
It is extremely important that each cutting edge
receives an equal amount of grinding to prevent an
unbalanced blade.
We do not recommend
the use of pressure
washers or garden
hose to clean your
unit. These may cause
damage to electrical
components, spindles,
pulleys, bearings, or
the engine. The use
of water will result in
shortened life and
