Cutting blade adjustment
It is essential that the relationship between the blade(s)
and mower body is kept in good adjustment and that
cutting edges are kept sharp to ensure good cutting
performance, minimum power consumption and
prolonged life for the cutting edges. Carry out the
following procedures before commencing work and
re-check the settings every 2 to 3 hours of mowing or
when the cutting performance is noticeably reduced.
During mowing, the blade tips can move relatively
to the mower body through normal work or by
hitting obstructions. Check that the cutting blade(s)
is correctly set to the mower body by measuring the
distance between the blades and the lawnmower
skirt, vertically. This distance should nominally be 3
mm. Disconnect the spark plug cable and carefully
rotate the blade by hand and check that the distance
is nominally correct all around the mower body. If
adjustment is necessary, proceed as follows:
•
Remove the
spark plug
cable from the
spark plug.
•
Rotate the
blade(s)
manually until
it is accessible
from the rear flap area.
•
Using a crescent spanner on the end of the blade,
apply an upward or downward force to correct the
distance.
•
Re-check each blade and make marginal
adjustments as necessary.
•
Re-fit the spark plug cable.
If it is impossible to obtain a good clean cut, it may
be necessary to take the mower to your local Service
Agent to have a new set of blades fitted.
Grass catcher
Your rotary lawnmower can be operated with the grass
catcher fitted, or removed as a utility mower.
Always disconnect the spark plug
lead when adjusting the blade, to
prevent accidental engine start.
Recommended check dimension 3mm inside mower body
Always shut off the engine and
ensure it has stopped before fitting
and removing the grass catcher or
raising the rear flap
Note that if the lawnmower is used with the catcher
removed, the rear flap must be fitted and located in
the down / closed position. To fit the grass catcher,
stop the engine and position the catcher on the
ground behind the mower. Raise the rear flap and lift
the catcher into position ensuring the catcher tongue
is located over the rear axle. Slide the catcher forward
and upward; lower the flap so that the lugs on the flap
locate into the square holes on top of the catcher. Your
catcher is now attached.
To remove the grass catcher, stop the engine, hold the
catcher by its top handle and raise the rear flap. Lift
the grass catcher up and away from the lawnmower
and return the grass flap to its down / closed position.
Avoid leaving the catcher in direct sunlight when not in
use. The catcher will not deteriorate if stored wet but
prolonged exposure to sunlight can cause premature
UV breakdown. Dust and clippings will build up inside
the catcher and on its venting screen, particularly
during wet weather mowing. This debris will impede
the function of the catcher so it should be removed by
hosing out with water when necessary.
Mulching models
Mulch mowing is recommended at the higher end
of the height of cut settings to allow a good even
cut and distribution of clippings through the lawn.
Mulch mowing involves different mowing practices
to conventional mowing and here are a few helpful
guidelines to provide the best results with your
mulching mower.
•
Avoid mulching the lawn in wet conditions. Wet
grass will build up on the inside of the body, fall off
in clumps and not spread evenly into the lawn. The
best time to mulch is in the late afternoon or early
evening. By this time the grass is usually dry and
the sensitive, newly cut grass is not exposed to the
direct sunlight.
Always wait until the engine has
stopped and the blade has stopped
rotating before fitting or removing
the mulcher plug.
