Part No. SCAZ043468 1.6.01 30 E&OE
Suction Path Blockage Clearance
Always wear appropriate personnel protective equipment (PPE).
A blockage in the suction path will be indicated by a trail of material behind the vehicle. The most likely cause is an obstacle either in the suction nozzle, or
the trunking immediately above it, around which other material collects as sweeping progresses. It is important that such problems are rectified as soon a
possible.
Before this can be achieved, however, the following health and safety concerns must be addressed. These are important and are intended to maintain safe
working conditions at all times, therefore:-
Never raise the hopper where the load it contains or the ground you are on could cause the machine to become unstable.
Never attempt to work beneath a partially raised hopper, i.e. where the safety prop cannot be deployed.
Never attempt to clear a blockage while the brushes are operating, always stop and retract all brushes, stop the engine and remove the ignition keys
before starting the procedure.
Always be aware of the risk from sharp objects and never place your hands into the blockage, even when wearing gloves. Exercise extreme caution
when handling any items removed from the suction system, keeping such activities to the absolute minimum.
Only when all of the foregoing points have been complied with, should the clearance procedure commence. If it is not possible to comply with these
conditions you are advised to consult your supervisor before acting.
The procedure for checking and clearing the blockage is as follows:
1. Raise the hopper, ensuring the hopper safety prop is deployed, to gain access to the top of the suction tube.
2. Visually check conditions inside the suction tube and nozzle box to determine the nature and location of the blockage and whether, without suction, the
blockage has dropped back to the road surface.
3. If the blockage is still present, use a suitable implement (a stout length of wood is ideal), to remove the obstacle by pushing it downwards.
4. Once the offending item has been successfully removed, restart the Machine and use the high-pressure hand lance, if fitted, to thoroughly wash out the
trunking and nozzle box.,
5. Lower the hopper, ensuring that the hopper safety prop has retracted, but do not start the suction fan at this stage.
6. Move the vehicle sufficiently to expose the cause of the blockage. Stop the Machine, apply the parking brake and remove the ignition key. Carefully
isolate the blockage and remove to a safe location.
7. Resume sweep mode. Lower the suction box and switch on the fan. Assure the suction is correctly functioning.
8. Return to the start of the trail created by the blockage and continue sweeping.
