Clearing a blockage in the suction path

Wear appropriate PPE.

Never raise the hopper where the load it contains or the ground you are on could 
cause the vehicle to become unstable.
Ensure that the hopper prop is fully engaged when the hopper is in the raised 
position, see page 9. Fail
ure to do so could result in serious injury.
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.

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.

2.

Raise the hopper 

, which deploys the safety prop. Stop engine. Remove 

ignition key.

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.

5.

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. Assure the 
suction is correctly functioning.

8.

Return to the start of the trail created by the blockage and continue sweeping.

Area most susceptible to blockage.
