GENERAL MACHINE MAINTENANCE - Cont.
RECYCLING PUMP ESP SYSTEM
The recycling pump is located under the seat. The pump is
electric and except for daily cleaning of the pump intake screens,
it requires no regular maintenance.
RECYCLING PUMP STORAGE
Always drain pump for extended storage, especially when
freezing temperatures may be encountered.
REAR SQUEEGEE
The squeegee will require service when the inner edges of the
blades become round with wear, impairing the wiping action or
water pickup. To service the rear squeegee use the following
steps:
1. Loosen the four aluminum knobs.
2. Remove the squeegee tool and turn upside down to
service the blades or caster wheels. The
squeegee blades are designed to flip over and use
another unworn edge.
To service the blades:
1.
Loosen the clamp bolts which clampsqueegee tool
together.
2.
Loosen far enough to slip the end clamp brackets off the
squeegee tool. This will allow flipping the blades or
installing new blades.
3.
Install blades so that the outer blade is 3/16” longer than
the inner blades. This is achieved by assembling the top
edge of the blade against the squeegee tool weldment.
4. Reinstall the squeegee clamp band and tighten the clamp
bolt.
SQUEEGEE CASTER WHEELS
There are two (2) grease fittings on each caster wheel. The
casters should be greased each time the blades are serviced.
ADJUSTING CASTERS
Lower the squeegee on a flat surface, making sure the rear
squeegee blade is perpendicular to the surface. Adjust the
caster 3/16” above the flat surface. Lock the jam nuts.
