INSTALLATION, OPERATION
& 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 installing, 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.

BC2™ COMPONENTS
XX - BELT WIDTH 30”, 36” or 72”
The BC-2™ is a Secondary Belt Cleaner designed to be installed on the return side of the belt.
Identify and become familiar with all the parts. Ensure all parts have been included. If mounting structure
is not available, additional steel may have to be added.
NOTE: Excess mounting tube may be trimmed after installation.

BC2™ INSTALLATION
1. DETERMINE CLEANER LOCATION
2. CUTTING THE CHUTE OPENINGS
Although BC-2 is a secondary cleaner and as such should be located on the return side of the belt after
the belt leaves contact with the head pulley, this system is designed that it will function at the
6 o’clock position on the pulley as shown below. Preferably it should be located within the confines of
the head or dribble chute.
If the brackets are to be mounted to an enclosed chute, an elongated
hole will have to be cut into the chute wall to allow the mounting tube
to pass through from one side of the conveyor to the other.
See Fig. 3.

Note that the bracket can be flipped either way to bolt
to existing structure. See Fig. 2.

3. MOUNTING BRACKETS
4. MOUNTING TUBE
Insert the tube with attached blades through the chute cut outs. Determine the desired position of the
mounting brackets. Attach the mounting brackets to the chute wall by welding or bolting through the
mounting holes along the mounting brackets’ length, or to the conveyor frame using the two holes on
top of each mounting bracket.
A - Dimension will always be to the left hand side of the conveyor when looking at the tail from the
head pulley and B - Dimension will always be on the right.

It is important to note, if using optional mounting positions over recommended
mounting positions, rotate tube along the tube axis, not end over end. This will
ensure the A and B sides of the tube remain in the correct orientation.

OPERATION
With all modules inserted, bring the mounting tube up towards the belt ensuring the tube remains paral-
lel to the belt line and pulley. It is recommended to have both the tips”bottomed” out in the slots as
well as the modules inserted completely into the mounting tube.
Raise the tube until the back arms touch the belt. If the front arms touch first, adjust the rake angle and
ensure the arms are fully inserted into the mounting tube.

5. ARM TO TUBE INSTALLATION
With mounting brackets bolted or welded in place, insert the
tube through the chute cut outs.
Arms should be inserted into the mounting tube, alternating
short and long arms. On belt widths that have odd numbers of
arm modules, more short arms will be included than long arms.
Starting with a short arm will ensure correct arm arrangement.
A set screw and jam nut are provided to fasten the arm modules
to the tube. Regardless of mounting orientation, the set screw
will be inserted in the “Top” hole of the mounting tube. Hand
tighten the set screw so that the modules will not move around
will adjusting the mounting tube height.
If belt profile is “cupped”, tip angle may be adjusted individually
for better belt contact. Fine adjustment may be necessary to
avoid any gaps between the tips and the belt. This adjustment
will need to be done at the installed location, which may be
within a chute or under a conveyor system.

BC2™ INSTALLATION
OPERATION CONT.
Adjust the short arms up so that the tips contact the belt. Tighten all set screws and jam nuts
completely.
Ensure the blade tip is contacting the belt and then tighten lock nuts on the blade tips.
Adjust the rear blade tips so that they are fully contacting the belt surface and tighten the lock nuts.
Once belt contact has been made, tighten the adjustment angle lock bolt. Turn the adjustment bolt
until the blade tip has moved about ¼”. Tighten the tube clamp lock bolts.
Test run the conveyor. If chattering occurs, loosen the tube clamp bolts and rotate the mounting tube
in the direction of belt travel.

BC2™ MAINTENANCE
AFTER ONE DAY OF OPERATION
WEEKLY
REPLACEMENT AND RETENSIONING OF CLEANER BLADES
Inspect the cleaner for proper belt cleaning and operation.
1. Frequent inspection is the key to proper belt cleaning and easy Scraper servicing. Weekly inspec-
tions are recommended, but actual service frequency may vary widely depending on various plant
operating conditions.
2. 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.
3. Carefully inspect the wear tips of the cleaner blades. Make sure blades are not chipped or worn
out. (Replace when necessary)
4. 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.
1. Lower mounting tube to disengage the cleaner blades from the belt.
2. Remove the clamp block to remove the tube from the mounting brackets.
3. Loosen and remove the nuts holding the blades onto the arms.
4. Remove the worn blades and discard.
5. Position new blades on the arms and reinstall the nuts and bolts to hold the blades evenly across
the cleaner edge.
6. Reinstall mounting tube with blades in place and tension according to directions

BC-2™ w/Bolt-Up™ Tensioner
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. If the belt is non-reversing, rotate the blade about 5°
degrees in the direction of the belt movement.
Install a hold down roller to stabilize 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.
