Cutting Height

CAUTION
For safety ensure that the Safety Key and Battery are
removed from the Mower before adjusting the height.
To ensure that the roller is aligned correctly, it is recommended
that the height is adjusted on a level surface. It is also
recommended that the Grass Collector be removed as this will
allow easier access to the Locking Knobs.
1. Pull out the knobs on both sides of the roller. (Fig 11)
Fig. 11
2. Holding both knobs, raise or lower the mower to the
desired height.
3. Allow the knobs to spring into the holes, ensure they sit
fully into the hole, are at the same height and properly
secured.

electronic circuit will warn of low battery level and RED LED
will be on, this indicates that the battery should be recharged
at this point.
GREEN LED ON–Normal operation.
RED LED ON–Battery flat, please charge to prevent over
discharge damage.

CAUTION
For safety ensure that the Safety Key and Battery are
removed from the Mower before adjusting the blade.
To adjust the blade turn the 2 bolts on the blade shield. The
cylinder should almost touch the blade, but do not over
tighten it. (Fig.13)

Cutting Cylinder
If the cylinder hits the blade,
it is too tight and will damage
the cutting edge; loosen
the nuts.
To check for correct
adjustment, insert a piece
of paper between the blade
and the cutting cylinder.
When the cutting cylinder
is turned by hand the paper
should be cut cleanly.
