4. After striking a foreign object, stop the engine
(motor), remove the wire from spark plug,
thoroughly inspect the mower for any damage, and
repair the damage before restarting and operating the
mower.
5.
If the equipment should start to vibrate abnormally,
stop the engine (motor) and check immediately for
the cause. Vibration is generally a warning of trouble.
6.
Stop the engine (motor) whenever you leave the
equipment, before cleaning the mower housing, and
when making any repairs or inspections.
When cleaning, repairing or inspecting, make certain
the blade and all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire
away from the plug to prevent acciderttal starting.
Do not run the engine indoors.
8.
9.
Shut the engine (motor) off and wait until the blade
comes to a complete stop before removing the grass
catcher or unclogging chute.
10.
Mow across the face of slopes, never up-and-down.
Exercise extreme caution when changing direction on
slopes. Do not mow excessively steep slopes.
11.
Always disconnect electric mowers (line operated)
before cleaning, repairing or adjusting.
12.
Never operate mower without proper guards, plates
or other safety protective devices in place.
Keep washout ports and other mower-housing service
13.
openings closed when mowing.
MAINTENANCE AND STORAGE
1. Check the blade and the engine mounting bolts at
frequent intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
3. Never store the equipment with gasoline in the tank
inside of a building where fumes may reach an open
flame or spark. Allow the engine to cool before
storing in any enclosure.
4. To reduce fire hazard, keep the engine free of grass,
leaves, or excessive grease.

FIGURE 28. STARTING
EFFICIENT OPERATION
CAUTION
Stop the engine and disconnect the
spark plug wire from the spark plug
before making any adjustments.
Deck—The underside of rpower deck should be
cleaned after each period of use as grass clippings,
leaves, dirt and other matter accumulates. This
accumulation of grass clippings, etc., is undesirable
as it will invite rust and corrosion and may cause
an uneven discharge of grass clippings at next
cutting.
12
Page 13
2. The deck may be cleaned by tilting the mower
backward or on its side and scraping clean with a
suitable tool or by washing with a stream of wa
ter from a garden hose.
CAUTION
Do not direct the stream of water at a
hot engine as damage to the engine
may result.
3. For best results do not cut wet grass because it tends
to stick to the underside of the mower, thus pre
venting 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, other
wise 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, discharge towards cut portion then recut
at right angle to first direction.
Lawns should be cut in fall as long as there is
growth.
WARNING
1
1. The mower should not be operated without the
entire grass catcher or chute deflector in place.
2. The mower should not be operated without the
protective shield on the rear of the deck in place.
