SWEEPING IN COLD TEMPERATURES
Operating Temperature 0°C To +5°C
For sweeping in cold conditions above freezing, it is possible to use the water system
providing the machine has been left in a warm garage overnight.
Care must be taken to ensure water sprayed onto the road does not freeze.
Do not use full suction capacity above 1500 rev/min. as the air speed up the nozzle could
cause the water to freeze.
Operating Temperature 0°C To -15°C
It is possible to use the machine for short periods without water in the tanks.
Sweeping can be carried out using low to medium suction 1200 - 1500 rev/min.
Note:
When operating the equipment without water dust will be emitted from the fan outlet, and
premature wear will be experienced on some components.
