2. Fit the display cover on the chassis.
Check that no cables are pinched
between the chassis and the display
cover. When assembling it is important
to first feed as much as possible of the
cables down into the chassis and then fit
the display cover on the chassis.
3. Screw the display cover and the chassis
together using the 4 screws (Torx 20). The
screws should be tightened crosswise.
4. Fit the HMI cable and the sensor cables
to the HMI circuit board.
5.2.5 Assembling the chassis
IMPORTANT INFORMATION
When assembling: Make sure parts are
clean and that no cables will be pinched.
An unsealed chassis can let in moisture,
which can result in faults in the mower.
Always use new sealing strips before
putting the chassis halves or the display
cover together. A sealing strip that has
already been used does not provide a
satisfactory seal.
1. Fit a new sealing strip to the lower section
of the chassis. Refer to 5.27 Assembling
the sealing strip on page 79.
Automowers 420, 430X and 450X have
a 5 millimeter sealing strip, unlike for
example models 220AC and 305, which
have a 4 millimeter strip.
IMPORTANT INFORMATION
A 5 mm sealing strip must be used on
Automower 420/430X/450X. Sealing may
be deficient if the wrong sealing strip is
used, leading to costly repair work.
