SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
2--15
Cab Pressurisation Monitor (where fitted)
To improve protection against chemical vapours
entering the cab when spraying, the blower can be
used, in conjunction with charcoal filters, to raise the
air pressure inside the cab above that of the external
air pressure. Whilst this differential is maintained,
chemical vapours should not enter the cab. Ensure
all cab apertures are fully closed. To monitor the
internal pressure, a gauge is mounted inside the cab.
Cab Air Pressurisation Gauge
Observe the reading on the pressure gauge. If the
lower edge (1) of the yellow indicator centres in the
green area you have an adequate differential
between the internal and external air pressure.
Adjust the blower speed to maintain that reading. If
the yellow indicator rises into the red area, increase
blower speed to raise the internal cab pressure.
CAUTION
If, during spray operations, the lower edge of the
yellow indicator enters the red section of the gauge,
carry out the checks below and follow the chemical
manufacturers recommendations for safe operation.
With the blower in the off position the yellow indicator
should move into the red area. If the indicator does
not register correctly, the gauge should be replaced
before operating with chemical spray equipment.

If the blower is unable to maintain the correct
pressure inside the cab then the following checks
should be made to determine the cause.
1. Check blower is on maximum speed.
2. Ensure all doors, windows and roof panel are
fully closed.
3. Check external air filters for blockage or
restriction.
4. Examine all cab aperture seals for damage.
5. Check sealing around linkages and levers where
they pass through the cab panels.
If, after all the checks have been made the cab
interior pressure cannot be maintained, consult your
authorised dealer.
