SWEEPING AND BRUSH INFORMATION

Pick up oversized debris before sweeping. Flattenor remove bulky cartons from aisles beforesweeping. Pick up pieces of wire, twine, string,etc., which could become entangled in the brushor brush plugs.

NOTE: Debris can be placed in the hopperthrough the hopper access door on the front of thehopper.

Plan the sweeping in advance. Try to arrange longruns with minimum stopping and starting. Sweepdebris from very narrow aisles into the main aislesahead of time. Do an entire floor or section at onetime. Drive the straightest path possible. Avoidbumping into posts or scraping the sides of themachine. Overlap the brush paths.

Avoid turning the steering wheel too sharply whenthe machine is in motion. The machine is veryresponsive to the movement of the steering wheel.Avoid sudden turns, except in emergencies.

For best results, use the correct brush type foryour sweeping application. The following arerecommendations for main sweeping and sidebrush applications.

Polypropylene 8-double row main brush --Superior pick-up of sand, gravel, and paper litter.Polypropylene retains its stiffness when wet andcan be used indoors or outdoors with equalperformance. Not recommended forhigh-temperature debris.

Polypropylene and wire 8-double row mainbrush -- The wire bristles loosen slightly packedsoilage and heavier debris. The polypropylenebristles sweep up the debris with excellent hopperloading.

Polyester 8-double row main brush -- Polyestercombines the durability of nylon with the moistureresistance of polypropylene.

Polyester 24-single row main brush --Polyester combines the durability of nylon with themoisture resistance of polypropylene. This highdensity brush is recommended for applicationsthat sweep heavy accumulations of fine dust, sandor other similar material.

Natural Fiber 8-double row main brush -- Thenatural choice for cleaning fine debris on carpetand sweeping very heavy dust and other fineparticles on hard surfaces.

OPERATION

6400 MP429EN (9--96)28

Polypropylene Side Brush -- A good generalpurpose brush for sweeping of light to mediumdebris in both indoor and outdoor applications.This brush is recommended when bristles may getwet.

Nylon Side Brush -- A longer life, generalpurpose brush that is recommended for roughsurfaces.
