& MAINTENANCE INSTRUCTION

SAFETY FIRST
WARNING
Always observe the basic rules of safety when working
with any conveyor system. To avoid injury and equipment
damage, be sure that all controls to the conveyor are
locked out and the power source is disconnected at all
times during installation.
Please completely read and understand these instructions before attempting the installation of the belt
cleaning system. Failure to do so could lead to serious injury and equipment damage. Ensure that all
controls and power sources to the conveyor system are properly disconnected and locked out while in-
stalling, adjusting or maintaining the belt cleaning system. Never attempt any installation, adjustment,
or service procedure while the conveyor is in operation.
Ensure that all required safety equipment is on hand, such as a fire extinguisher and first-aid kit before
proceeding. Those who use and maintain the belt cleaning system must be properly trained in its
proper use, know of its dangers, and read and understand this entire manual before attempting to
install, operate, or service this device. Failure to observe all instructions could result in serious injury.
It is the owner’s responsibility that the owner and each operator read and be familiar with this manual.
Please contact our ASGCO engineering Department at 1.800.344.4000 if you have further questions or
are unsure of these procedures.

USCRAPE™ INSTALLATION
DETERMINE CLEANER LOCATION
MOUNTING BRACKET
The U-Scrape™ is a Secondary Cleaner and as such should be located on the return side of the belt
after the belt leaves the head pulley as shown below. Preferably not much further from the confines of
the head or dribbled chute.
Determine the desired position of the mounting brackets. Attach the mounting brackets to the conveyor
frame using the two holes on top of each mounting bracket.

Step 2
Hang the U-Scrape with its tube on the bush-
ing adj. angles, and slide on the 2 each tube
bushings.
Step 3
Next bolt into place the tube bushings using
the supplied hardware.
USCRAPE™ INSTALLATION
PROCEDURE
Step 1
Pre-assemble the spring hanger extension
brackets to the spring plates, and the bushing
adjusting brackets with supplied hardware
before hanging the bolt-up brkts.
Mount the bolt-up brackets first. The mounting holes need to accept 1/2” bolts. You can install the bolt-
ups with the supplied hardware and leave the brackets hanging down just enough to install the spring
plates. Then tighten the bolt-ups down.

Step 4
Next insert the locking collar and the power arm,
and the machine screw & nut. Put on the end
caps, do this to both sides, tighten both lock
collars only.
Step 5
With an extra hand, have someone push the
U-Scrape cleaner up against the belt. Install
both springs, move the power arms downward
until there is some tension on the springs and
tighten the set screws on the power arm.
Step 6
To properly tension the U-Scrape, adjust
machine screw until each spring is extended
the distance listed in the chart, based on
your belt width.

OPERATION
Additional adjustments will be made on the nut for the machine screw that is attached to the spring.
If tube bushings are at the same location in relationship to the conveyor frame, both nuts need to be
tightened equally for even tension.
Test run the belt to see how well the cleaner is functioning.

TROUBLE SHOOTING
After one day of operation
• Inspect the cleaner for proper belt cleaning and operation.
Weekly operation
• Frequent inspection is the key to proper belt cleaning and easy Scraper servicing. Weekly
inspections are recommended, but actual service frequency may vary widely depending on
various plant operating conditions.
• Wash the entire cleaner regularly to prevent excessive buildup. If material tends to accumulate
on the Scraper Assembly then possible scraper relocation may be in order.
• Carefully inspect the wear tip of the cleaner blade. Make sure blade is not chipped or worn out.
(Replace when necessary)
• Inspect the belt surfaces and edges for cracks, splits, tears, holes or any other worn or damaged
condition occurring on the surfaces or edges of the belt itself. If necessary make repairs to the belt.
• Upon wear, it will be necessary to tightened the spring up using the nuts on the machine screw.
• When running out of thread on the machine screw, you will need to adjust the cleaner upward
using the bolt for the adjusting angle. Loosen the tube bushing bolts first to do this.
• There is even more upward adjust using the hanger extension bracket, or downward movement
of the power arms.
SolutionProblem
Excess vibration of the scraper.
Excess carryback.
Excess belt movement, cupping.
Unable to tension scraper properly,
belt moves away from blades.
Frozen material on scraper.
Make certain all bolts are tight. Move the center line of the tube closer to the belt
Install a hold down roller to stabilizer the belt surface.
Check for proper Scraper tension. Put additional tension on cleaner.
Check for wear on the cleaning tip.
Check thickness of carryback. If the cleaner must remove more than about 1/8” of material then an
additional cleaner may be needed
Install a hold down roller to reduce sag of the belt when tensioning.
Place heaters near scraper to melt frozen material. Or shut off the belt lock it out, test that the belt
does not turn on, and chip debris off. CAREFULLY . Use caution not to burn belt or cleaner.
