The Sludge Scraper removes sludge from the power washer's reservoir to a bin or
barrel. The materials to be removed by the sludge scraper can be any solid material or
any material that is of a consistency that will not run off of the scraper bars.
The sludge scraper provides these benefits.

18.1. Theory of Operation
The washer is mounted on the sludge-scraper assembly, which replaces the original
floor of the washer's reservoir. Part of the assembly extends as a chute behind the
washer at a 45-degree angle.
When the Sludge Scraper is operating, angle scrapers move across the bottom of the
reservoir, collecting sludge and carrying it up the chute. At the end of the chute, the
sludge drops into a bin or barrel. The scrapers then move back down the chute into the
washer reservoir and begin to scrape the bottom of the reservoir.
The scrapers are attached to a sprocket-mounted drag chain that continuously rotates.
The drag chain is chain-driven by a gear motor through a sprocket torque-limiter.
The gear motor is a variable-speed DC-drive motor, with a speed controller located in
the washer's electrical control panel. You can set the motor from low to high speed.
