Health and Safety advice
• Only trained operatives should be allowed to drive or work on this machine.
• Never work under a raised hopper or rear door without the appropriate safety prop in position.
• Do not drive the vehicle with the hopper raised. The red warning symbol on the LCD monitor remains illuminated until the hopper is fully
down.
• Before working on the vehicle ensure that it is on firm, level ground, apply the hand brake, stop the engine and remove the ignition key.
• Before raising the hopper or opening the rear door, ensure that there is sufficient clearance and it is safe to do so.
• Before starting the auxiliary engine, ensure that all controls are switched off and the vehicle’s gearbox is in neutral.
• Before driving the vehicle, ensure that all vehicle checks have been carried out and that all equipment is stowed and that brush(es) are
raised.
• Do not overload the hopper.
• High pressure water can be dangerous, always wear suitable eye protection when operating the high pressure water pump nad when using
the lance. Do not direct the water jet at other persons. Beware of electrical installations on public buildings and lamp posts etc. and always
exercise extreme caution in public places.
• The suction fan is an extremely heavy rotating mass. Vibrations emanating from the suction fan must be investigated, the cause
determined, and rectified immediately.
• When working on the suction fan. Never attempt to slow or stop the fan by using the hands or by inserting any item into the fan chamber,
even at low speeds. failure to comply can result in serious injury.
• When operating the machine in any mode always be aware of objects and people in the immediate vicinity, especially at the rear of the
machine when reversing.
• Whatever the situation, remember that the rules of traffic and road safety must be observed.
• While operating this machine the safety and well being of other people are the sole responsibility of the operator.
Cautions
If the suction fan vibrates, it should be cleaned immediately (refer to the operating instructions). Prolonged vibration will result in damage
to the fan, bearings and, in extreme cases, the hopper.
In the event of a hydraulic oil leak, stop the engine and investigate.
The high and low pressure pumps must never be permitted to run dry or the piston seals will be damaged.
Do not direct the high-pressure jet directly at paintwork or electrical connections on the vehicle.
Routine daily maintenance
1. Check vehicle’s general condition (including tyres, lights and all fluid levels) in accordance with chassis manufacturers’ recommendations.
2. Check hydraulic oil level. (note: if the oil level is not maintained, the sweeping panel will automatically shut down until the oil level is correct).
3. Check condition of brushes and remove any items such as string that may be entangled.
4. Check ground clearance of suction box rubber flaps (20 mm front / 30 mm rear & sides) suction power can be lost if clearances are incorrect
but it is possible to slightly vary these settings to better suit specific sweeping conditions according to operator’s experience.
5. Check water spray jets for blockages.
6. Clean the oil cooler and check that cooling fan functions (note: if fitted, red light and buzzer operate when maximum temperature is reached).
7. Wash the vehicle, ensuring that the suction fan and hopper screens are cleaned.
8. Lubricate brush links, pivot points and wide sweep bearings.
9. Remove and clean the water-strainer elements.
10. Always leave the vehicle with the rear door slightly open to allow water to drain out.
11. In frosty weather, drain pumps & tank, remove water-strainer elements, switch on all water sprays and run low-pressure pump until dry.
Hydraulic oil: HPL 32 or an equivalent.
Coolant: Ethylene Glycol (Eskimo long life).
Engine oil: 15w - 40
