To Commence Sweeping
1. Start vehicle engine.
2. Ensure the intake blanking plate is not blanking the tube and is stowed on the body underside.
3. Start auxiliary engine.
4. Ensure warning beacons are operating - switch (R).
5. Ensure programme button (L3) is not illuminated.
6. Increase engine speed up to 1500 rev./min.
7. Lower pick-up head (G2) and lower channel brushes (gutter brooms) as required (E1/E2).
NB:
The brushes move out to their full working position whilst turning. Third position activates Hood
Water Sprays.
8. Set additional water jets to suit the debris being swept (J2, K2). Always operate (K3) body
interior sprays.
9. Commence sweeping at a forward speed between 2-12 kph depending upon the debris being
swept. Always use the slowest channel brush between 10 and 100 rpm to give satisfactory
suction performance.
10. The position of the channel brush can be altered (moved towards the chassis) by operating
switches C1 and C2 for the LH and RH channel brushes.
11. The channel brush ground pressure can be reduced by operating the Powasave regulations
BB.
