Cab Ventilation
The cab side windows are fitted with over centre catches, which permit opening for fresh
air circulation and also act as a stay to hold them open at the desired position. When two
catches are fitted, open them simultaneously or breakage of glass may occur.
Do not open windows when hazardous dust and or chemicals are in the
atmosphere and ensure that sufficient air is drawn into the cab through the
filters to maintain a positive pressure within the cab to keep dust and vapours
out.
Note: Make sure the climate control unit is switched off when the windows are open.
