SERVICE AND MAINTENANCE
Caring For Hoses
1.Inspect hoses before each use. If hoses have excessive wear, tears, or punctures, replace immediately.
2.To prolong the life of the hose, periodically rotate hose and turn hose end to end. Refer to Preventative Maintenance Schedule in this manual.
3.Avoid twists and sharp turns in the hoses, as they will increase wear on the hoses.
4.Avoid dragging the lower hose along the sides of buildings or other hard surfaces.
Cleaning Poly Mesh
The poly mesh on the collection system is located inside the container hood. For best results, clean poly mesh regularly.
DO NOT USE THE COLLECTION SYSTEM WITHOUT POLY MESH SECURELY IN PLACE.
