(Fig. 30)
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.
7-6 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.
7-7 GRASS CATCHER
There is a level indicator on the top of the grass catcher
that shows whether the catcher is empty or full
(Fig. 32,
Fig. 33) :
- The level indicator inflates if the catcher is not full
during the moving. (Fig. 33)
- If the catcher is full, the indicator collapses; once this
happens, stop moving immediately and empty the
catcher, make sure it is clean and ensure its meshwork
is ventilated.
(Fig. 32)
IMPORTANT
If the position of indicator opening is very dirty, the
indicator will not inflate-in this case, clean the position of
indicator opening immediately.
7-8 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).
7-9 HEIGHT ADJUSTMENT
INSTRUCTIONS
CAUTION: Do not at any time make any
adjustment to lawn mower 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 8 height positions.
The height (the blade to the ground) can be adjusted from
20 mm to 75 mm (8 height positions).
(Fig. 34)
The lowest adjustment: 20 mm (position 1), the highest
adjustment: 75 mm (position 8).
1. Stop mower and disconnect spark plug cable before
changing mower cutting height.
2. The central height adjustment lever offers you 8
different height positions. (Fig. 34)
To change the height of cut, squeeze adjustment lever
toward the wheel, moving up or down to selected height.
