Clearing A Blockage In The Suction Path - Scarab MERLIN Operating And Basic Maintenance Instructions

A blockage in the suction path will be indicated by a trail of material behind the vehicle.
Use the following instruction 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,
The hopper prop must always be used when the hopper is in the raised position. 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
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.
