ENGINE
The normal engine operation and maintenance procedures are covered in a separate manual,
which is furnished by the engine manufacturer. We do suggest, however, due to the dusty conditions in
which these machines operate, that engine fan inspection and replacement should be accomplished
more frequently than the engine manufacturer may suggest. Inspect the fan every 300 to 400 hours. The
dust in the air will eventually erode the fan blades to a condition that may cause a safety hazard or an
operational failure. Replace the fan if it is deteriorated to the point that it may not provide enough air
movement for cooling or when the blades become too sharp or too chipped to safely perform maintenance
around. This erosion is considered to be a normal wear item on this type of machine.
STORAGE
The storage of this machine follows the pattern of any construction equipment. We do however
recommend that when leaving a machine out in the weather that has wire as part of the core and it is
exposed to the weather, a light spray of oil be applied to retard rusting.
Do not store polypropylene (poly) brushes in direct sunlight! Polypropylene is chemically affected
in direct sunlight. After prolonged exposure to sunlight, the material can deteriorate and will greatly
shorten the life of the bristle.
Do not let this machine sit with the sweeping core lowered with the weight on the bristles. This
will cause a flat spot on the brush and make it bounce when in use. To avoid this, use a cylinder stop on
the sweeping core lift cylinder to hold the bristles off the ground or use blocks under the ends of the
core frame.
BROOM WAFERS
Poly wafers are used in normal dry sweeping conditions: dirt, sand, leaves and other light
debris. These types of jobs will give the wafers their longest life. Poly is recommended for most
applications due to their increased flicking ability and is more economical to replace.
A combination of ½ poly and ½ wire wafer is not recommended except in conditions where
aggressive sweeping is needed. In most cases the standard all poly brush will be adequate. The wire
wafers will wear faster than the poly and cost much more to replace. Wire has sharp tips for cutting
action and can reach down into cracks and crevasses better than poly. The sharp ends of the wire cut
through ice and snow faster than poly wafers. We recommend no more than a 2” down pressure pattern
be used with wire wafers or a combination of poly and wire to prevent breakage of the bristles. If too
much down pressure is exerted on the bristles they will flex too much and break off close to the wafer
base, leaving the bristles on the pavement. Excessive down pressure reduces broom life considerably.
The life span of brush wafers is directly related to the way they are used. When properly used
the brush wafer life can be extended by 50 to 100 hours.
