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 1600 engine rpm 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 engine rpm.
Please note that some dust may be emitted from the fan outlet, and premature wear may be
experienced on some components.
