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.
RECOVERY TANK LID AND TANK ACCESS
Remove the two hex head screws to access the inside of the recovery tank lid. The hydraulic oil cooler is located
inside the lid. To gain access to the Recovery Tank, open the engine cover and loosen the hold down strap located
on the side of the recovery tank.
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 flip over and use another unworn edge (item 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 flipping the blades or
installing new blades.
3. Install blades so that outer blade is 3/16” 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.
SQUEEGEE CASTER WHEELS
Grease caster wheel zerks (2) on each caster should be greased each time the blades are serviced for a total of 3
caster wheels.
ADJUSTING CASTERS
Lower squeegee on a flat surface, making sure the rear squeegee blade is perpendicular to the surface. Adjust
caster 3/16" above the flat surface, Lock jam nuts.
