Adjustment of engine lockout switches: The
micro switch must be positioned such that when
the actuating levers (transmission neutral detent
lever or cutter clutch idler arm) are in the neutral/
disengaged position the switches must be fully
closed. To adjust, set the appropriate lever in the
neutral/disengaged position, slacken off the switch
mounting bolts and slide the switch along its
mounting slots until the switch is heard to click
shut. Retighten mounting bolts.
Check the operation of the operator presence con-
trols, refer to DAILY BEFORE USE.

IMPORTANT: PREVENT DAMAGE - It is
essential that the relationship between the
bottom blade and the cutting cylinder is kept in
good adjustment in order to ensure good
cutting performance, minimum power con-
sumption and prolonged life for the cutting
edges.
Cutterhead cylinder to bottom blade adjust-
ment: Carry out the following procedure before
commencing work and re-check the settings every
few hours.
Check that the cutting cylinder is correctly set to
the bottom blade by holding a thin piece of paper
between the cutting cylinder and the bottom blade
as shown. Carefully rotate the cylinder and check
that the paper is cut cleanly at all points along the
length of the blade. Hold the paper at 90 degrees
(right angles) to the bottom blade to obtain the cor-
rect cutting action.
If adjustment is necessary proceed as follows:
Slacken the nearside and offside setscrews ‘A’.
Slacken both locknuts ‘B; and turn the adjusting
nuts ‘C’ in a clockwise direction. The adjust-
ing nuts should be rotated one flat of the nut at
a time, alternating end to end, while rotating the
cutting cylinder backwards until it is felt to be in
‘fleeting’ contact with the bottom blade along its
entire length. Re check the cutting action along the
length of the bottom blade using a thin piece of
paper and making marginal adjustments as neces-
sary.
