5. Operating the Mower
1. Set the height of c ut appr opr ia t ely for the condition of the lawn. Where the grass is long or wet, then ensure the hei ght of
cut is high initially. Reset the height of cut to the required height after first mowing the long grass.
2. For the best results only cut dry grass and cut regularly when the grass growing quickly.
3. Mow in parallel lines with a small overlap.
6. Adjustment / Maintenance of the Cutting Blades
The blade system has a cylinder blade which rotates within the mower housing against the bottom blade. The cutting action
is similar to a pair of scissors and when adjusted correctly will provide ideally a clean cut of each leaf of grass. Take care to
avoid contact with the sharp blades whilst undertaking the adjustment.
1. The hexagonal screws on the
bottom blade assembly allow the distance
from the cylinder and the bottom blade to be
adjusted.
2. Turn the hexagonal screw
clockwise moves the bottom blade closer to
the cylinder. Reversely, anti-clockwise moves
the blade from the cylinder.
3. Adjust the setting so th at the blades
are just touching. When they are too close
mowing will be difficult and noisy. Adjust so
that the blades rotate easily, but are still in
contact and cutting, rather than ripping the
grass.
4. Periodically check the blade adjustment.
