CAUTION:
• Your mower is designed to cut normal residential grass
of a height no more than 250 mm.
Do not attempt to mow through unusually tall dry or wet
grass (e.g., pasture) or piles of dry leaves. Debris may
build up on the mower deck or contact the engine exhaust
presenting a potential fire hazard.
10.6 FOR THE BEST RESULTS WHEN
MOWING
Clear lawn of debris. Be sure that the lawn is clear of
stones, sticks, wire or other foreign objects which could
be accidentally thrown out by the mower in any direction
and cause serious personal injury to the operator and
others as well as damage to property and surrounding
objects. Do not cut wet grass. For effective mowing
do not cut wet grass because it tends to stick to the
underside of the deck preventing proper mowing of the
grass clippings. Cut no more than 1/3 the length of the
grass. The recommended cut for mowing is 1/3 the length
of the grass. Ground speed will need to be adjusted so
the clippings can be dispersed evenly into the lawn.
For especially heavy cutting in thick grass it may be
necessary to use one of the slowest speeds in order to
get a clean well mowed cut. When mowing long grass
you may have to cut the lawn in two passes, lowering the
blade another 1/3 of the length for the second cut and
perhaps cutting in a different pattern than was used the
first time. Overlapping the cut a little on each pass will
also help to clean up any stray clippings left on the lawn.
The mower should always be operated at full throttle
to get the best cut and allow it to do the most effective
job of mowing. Clean underside of deck. Be certain to
clean the underside of the cutting deck after each use
to avoid a build-up of grass, which would prevent proper
mulching. Mowing leaves. The mowing of leaves can also
be beneficial to your lawn. When mowing leaves make
sure 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.
