MAINTENANCE
Cutting Blade—The blade may easily be removed
for grinding or replacement as follows :
1. Remove bolt and lockwasher holding blade
and blade adapter to engine crankshaft.
2. Remove blade and blade adapter from engine
crankshaft.
3. Remove two bolts, lockwashers and nuts
holding blade to blade adapter (if necessary).
When sharpening blade, follow the original angle
of grind as a guide. It is extremeiy important that
each cutting edge receives an equai amount of
grinding to prevent an unbalanced blade. An
unbalanced blade will cause excessive vibration
when rotating at high speeds and may cause
damage to the mower. Upon reassembly, make
certain all parts are assembled properly and
tightened securely.
NOTE
To ipsure safe operation of your
unit, all nuts and bolts must be
checked periodically for correct
tightness.
Deck—The underside of the mower deck shouid
be cleaned after each period of use as grass
clippings, leaves, dirt and other matter wiil
accumulate. This accumulation of grass clip­
pings, etc., is undesirable as it will invite rust and
corrosion and may cause an uneven discharge of
grass clippings at the next cutting.
The deck may be cleaned by tilting the mower
forward or on its side and scraping clean with a
suitable tool or by washing with a stream of water
from a garden hose.
A'
____ ^CAUTION
Do not direct the stream of water at
a hot engine, as damage to the en­
gine may result.
STORAGE
The following steps should be taken to prepare
lawn mower for storage:
1. Clean and lubricate mower thoroughly as
described in the preceding instructions.
2. Refer to engine manual for correct engine
storage instructions.
3. Coat mower’s cutting blade with chassis
grease to prevent rusting.
4. Place blocks under deck to raise tires clear of
floor.
5. Store mower in a dry, dean area.
USING YOUR ROTARY
MOWER
For best results, do not cut wet grass because it
tends to stick to underside of the mower thus
preventing proper discharge of grass clippings. If
wet grass must be cut, reduce walking speed to
help distribute the clippings more effectively.
New grass should be treated as wet grass,
otherwise a normal walking speed is about the
right pace for efficient mowing. The best mowing
pattern is one that allows the clippings to
discharge towards the uncut part of the lawn. This
permits recutting of the clippings to further
pulverize them. When cutting high weeds, dis­
charge towards cut portion, then recut at right
angles to first direction.
Lawn should be cut in the fall as long as there is
growth.
