Operation Continued
Unclogging a Clogged Hose
With engine running and unit secured to a trailer, truck bed, or other similar surface, fully
stretch hose in a straight line to dislodge the clog. If the clog will not clear, turn unit off, and
allow engine to come to a complete stop. Remove hose and manually clear the hose clog.
Note: The clogged debris may be sharp. Always wear durable gloves when removing clogs.
Unclogging a Clogged Housing or Exhaust Elbow
1. Turn engine off and wait for impeller to come to a complete stop.
2. Disconnect spark plug wires and battery cables.
3. Remove the hose from the housing and determine where the clog is located.
4. If possible, clear the clog through the intake opening. It may require removal of the intake
adaptor (item 6) to allow access to clear the housing.
5. If clog is in the elbow, carefully remove the elbow. Remove elbow by removing the bolts
and nuts on the elbow clamp so that the plates can be removed.
Note: Elbow is very heavy. Do not stand directly under elbow during removal!
Danger: The clog may contain sharp materials. Clear the clog wearing durable gloves!
Reconnect spark plug wire.
Hose Care
To increase hose life, periodically rotate hose and reposition nozzle and coupler on front
plate of unit. This ensures that the hose will not wear on only one side, further increasing its
life.
Keep hose as straight as possible and avoid sharp bends during operation for best pick-up
and to avoid clogs. Never drag hose. Always remove and store hose before transporting
unit. Store hose straight and flat to maintain flexibility for next use.

Maintenance

Interlock System

ing engine to run. Hose must be installed and switch
