GENERAL MACHINE MAINTENANCE
RECYCLING PUMP ESP SYSTEM
The recycling pump is located directly behind and under the recovery tank. The pump is electric and except for daily
cleaning of the pump intake screens, it requires no regular maintenance.
NOTE
Do not run pump dry. The unit depends on the liquid pumped for lubrication.
RECYCLING (ESP) 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 item 10, (these hold the squeegee tool to the squeegee support).
2. Remove the squeegee tool and turn upside down to service the blades or caster wheels. The squeegee blades are
designed to fl ip over and use another unworn edge (items 5 & 6).
TO SERVICE THE BLADES:
1. Loosen the clamp bolts, which clamp items 8 & 9 together.
2. Loosen far enough to slip the end clamp brackets off the squeegee tool. This will allow fl ipping the blades or
installing new blades.
3. Install blades so that outer blade is 3/16” (4.7 mm) longer than inner blades, this is achieved by assembling the top
edge of the blade against the squeegee tool weldment.
4. Reinstall squeegee clamp band and tighten clamp bolt tight.
