they are dry and are not laying too thick on the lawn. Do
not wait for all the leaves to be off the trees before you
mow.
WARNING: If you strike a foreign object, stop the
engine. Remove wire from spark plug, thoroughly inspect
the mower for any damage and repair the damage before
restarting and operating the mower. Extensive vibration of
the mower during operation is an indication of damage.
The unit should be promptly inspected and repaired.
8-6 GRASS CATCHER
Empty and clean the bag, make sure it is clean and
ensure its meshwork is ventilated. (Fig. 23)
8-7 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 scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
8-8 HEIGHT ADJUSTMENT
INSTRUCTIONS
CAUTION: Do not at any time make any
adjustment to lawnmower without first stopping the engine
and disconnecting the spark plug wire.
CAUTION: Before changing mowing height, stop
mower and disconnect spark plug cable. Your mower is
equipped with a central height adjustment lever offering
5 height positions.
1. Stop mower and disconnect spark plug cable before
changing mower cutting height.
2. The central height adjustment lever offers you
5 different height positions.
3. To change the height of cut, squeeze adjuster lever
toward the wheel, moving up or down to selected
height (Fig. 24). All wheels will be in the same height
