Operating Instructions
Clearing a blockage in the suction path
A blockage in the suction path will be indicated by a trail of material behind
the vehicle.
Use the following instructions and the diagram opposite to locate and remove
the obstruction:-
1. With all sweep equipment retracted and stowed.
Never raise the hopper where the load it contains or the ground you are
on could cause the vehicle
to become unstable.
2. Raise the hopper
, deploying the safety prop. Stop engine. Remove
ignition key.
The hopper prop must always be in the deployed position when working
under a raised hopper. Failure to do so could result in serious injury.
3. Visually check the suction path to determine the nature and location
of the blockage. If no blockage is present, further investigation of the
suction system will need to be carried out.
4. 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.
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.
5. Stow the hopper prop and lower the hopper
but do not start the
suction fan at this stage.
6. Move the vehicle sufficiently to expose the cause of the blockage.
Stop the vehicle, apply the parking brake and remove the ignition key.
Carefully isolate the blockage and if appropriate, place it in the hopper
via the side loading hatch.
7. Resume sweep mode. Lower the suction box and switch on the fan. Ensure the suction is correctly functioning.
8. Return to the start of the trail created by the blockage and continue sweeping..
