Hydraulics / Air conditioning
Spool valves
The Hydraulic spool valves are operated by mini joystick controls on the main control panel. The decal around the joysticks indicates the normal control functions for spray boom folding. There may be up to 6 valves fitted (4 normally fitted as standard) which can be any combination of single and double acting spools. A double acting spool can be safely used to operate a single acting service if required.
The hydraulic system/spool valve(s) fitted are only designed for intermittent operation of hydraulic cylinders and should not be used to power motors or other hydraulic circuits. Maximum pressure at the spools is approx. 2300 psi (160bar) Please consult the manufacturer if you require higher pressures or if wish to use them for any other purpose.
Please ensure that all couplings are clean before connecting hoses and that any couplings that are not in use are protected with plugs / caps. Ingress of dirt into the hydraulic system can lead to premature wear and possible failure of major components.

Air
Conditioning / ventilation
The air conditioning unit is integrated into the ventilation system within the cab roof. The unit will cool or heat the air which is partly drawn in to the cab through a carbon filter and partly re-circulated. This ensures the cab is kept positively pressurised to keep dust and vapours out of the cab.
Operation
To operate the
fan, turn the centre switch in the roof panel clockwise until you
find the most preferred of the three speeds. The adjustable vents in
the roof console can be directed to wherever you require the air.
To reduce the
temperature of the air, turn the RH switch clockwise until the cab
temperature is reduced as required. For maximum efficiency the LH
control for the heater should be turned fully anti-clockwise.
Remember the chiller will only work when the engine is running at
over 800 rpm.
Always keep the
cab door closed to keep the cab cool.
To increase the
temperature of the air turn the LH heater control clockwise and the
chiller control anti-clockwise.
