Section 1 - Important Information
1.1 General Introduction
Page 5
3
Before installing and operating the U-Type® Secondary Cleaner, it is important to review and understand the following
safety information.
ere are set-up, maintenance and operational activities involving both stationary and operating conveyors. Each
case has a safety protocol.
2.1 Stationary Conveyors
e following activities are performed on stationary conveyors:
• Installation • Blade replacement • Repairs
• Tension adjustments • Cleaning
DANGER
DANGER
WARNING
WARNING
WARNING
!
!
!
!
!
It is imperative that OSHA/MSHA Lockout/Tagout
(LOTO) regulations, 29 CFR 1910.147, be followed before
undertaking the preceding activities. Failure to use LOTO
exposes workers to uncontrolled behavior of the belt
cleaner caused by movement of the conveyor belt. Severe
injury or death can result.
Before working:
• Lockout/Tagout the conveyor power source
• Disengage any takeups
• Clear the conveyor belt or clamp securely
in place
Use Personal Protective Equipment (PPE):
• Safety eyewear
• Hardhats
• Safety footwear
Close quarters, springs and heavy components
create a worksite that compromises a worker’s
eyes, feet and skull.
PPE must be worn to control the foreseeable
hazards associated with conveyor belt cleaners.
Serious injuries can be avoided.
2.2 Operating Conveyors
ere are two routine tasks that must be performed while the conveyor is running:
• Inspection of the cleaning performance
• Dynamic troubleshooting
Every belt cleaner is an in-running nip hazard. Never
touch or prod an operating cleaner. Cleaner hazards
cause instantaneous amputation and entrapment.
Never adjust anything on an operating cleaner.
Unforseeable belt projections and tears can catch
on cleaners and cause violent movements of the
cleaner structure. Flailing hardware can cause
serious injury or death.
Belt cleaners can become projectile hazards.
Stay as far from the cleaner as practical and use
safety eyewear and headgear. Missiles can inict
serious injury.
Section 2 - Safety Considerations and Precautions

Section 3 - Pre-Installation Checks and Options
3.3 Correct Blade Installation and Tensioning
For optimal cleaning eciency and long wear life, the U-Type® blade must be located and tensioned correctly on
the belt. If the cleaner pole is in the wrong location the performance of the new blade may be adversely aected.
See “Possible Problems” below. For tensioning, please follow these instructions.
Correct Tensioning:
Correct tension is determined and set by blade width. Check the information provided with the tensioner being used
or consult the installation instructions.
Possible Problems:
• Pole location too low - e initial cleaning will be
concentrated in the center of the belt, failing to
clean the outer edges eciently.
• Pole location too high - e intial cleaning will be
concentrated to the outer edges of the belt, failing
to eciently clean the center of the belt.
• Tension too low - Without the optimal tension,
the cleaning eciency is reduced and chatter or
bouncing of the blade can occur.
• Tension too high - Although the cleaning may
appear ecient, accelerated blade wear may
occur; and in some cases less eciency on the
outer edges of the belt, which could result in
increased belt wear.
Correct Pole Location:
When the blade contacts the belt (before tensioning)
there should be blade-to-belt contact across the
entire blade (Fig. 1). If contact is more in the center
with a gap on the outer edges, the pole will need to
be raised until full contact is achieved (Fig. 2). If
contact is more on the outer edges with a gap in the
center, the pole will need to be lowered until full
contact is achieved (Fig. 3).

UST Tensioner Instructions
1. Choose conveyor location where cleaner will be installed.
e U-Type may be positioned at any spot from where belt leaves head pulley on down the conveyor line (see
positions A to B). If a chute area is too small due to a snub pulley, it may be necessary to mount cleaner behind
chute (see position C). In chute applications a minimum of 150-200mm (6”-8”) is required between cleaner and
chute wall to prevent clogging of material.
NOTE: For U-Type cleaners using UST Tensioners, proceed to Steps 2U - 7U.
For U-Types using J-Bolt Tensioners, skip ahead to Steps 2J - 8J on Page 10.

4U. Tighten torque arm set screws.
a. Spring tension nuts should be moved near the end of the threaded rod. Insert a screwdriver or small rod
through holes on end of cleaner pole. Pushing on screwdriver or rod, rotate cleaner blade into a position
with pole parallel to belt (Fig. 4Ua). Blade should not be touching belt at this time. e gap between the torque
arm and pivot block should be approximately 50mm (2").
b. Center the blade to the belt and make sure torque arm, stop collar, bearing and slide plate are tight together on
both sides. en tighten stop collar set screw and lock nut with stop collar touching top of bearing mount stop
to hold blade parallel to belt, and remove screwdriver or rod.
c. Push torque arm down to contact the spring and tighten the torque arm set screws and lock nuts on both sides
of the cleaner (Fig. 4Ub).
6U. Set the blade tension.
a. Set spring length to determined length (Fig. 6U).
Tighten spring tension nuts on threaded rod.
IMPORTANT: Always be sure there is uniform
contact between blade and belt.
b. If blade is not in full contact with belt at edges
and center, either raise or lower pole position of
cleaner and reapply tension.
c. Please note, when fully tensioned there should be
approximately 19mm to 38mm (3/4" to 1-1/2")
of space between the torque arm and pivot block
(Fig. 5U).
5U. Adjust the blade to the belt.
a. Loosen slide plate set screws and lock nuts. Adjust by
turning adjusting bolts either up or down (Fig. 5U).
b. Adjust blade either up or down until both blade ends and
the center make full contact with belt. If possible, adjust
both sides of the cleaner up to the belt at the same time
for even blade contact across belt (reduces chance of
overtensioning on one side).
IMPORTANT: In some cases, due to irregular belt wear
or cupping, it may be necessary to make nal adjustments
independently on both sides.
c. Tighten lock nuts on adjusting bolts to secure blade in
correct position. Also tighten slide plate set screws and
lock nuts.

problems or when adjustments are needed later.
5.1 Pre-Op Checklist
5.2 Test Run the Conveyor
Page 16
14 U-Type® Secondary Cleaner
Section 6 - Maintenance
Flexco belt cleaners are designed to operate with minimum maintenance. However, to maintain superior
performance some service is required. When the cleaner is installed a regular maintenance program should be
set up. is program will ensure that the cleaner operates at optimal eciency and problems can be identied
and xed before the cleaner stops working.
All safety procedures for inspection of equipment (stationary or operating) must be observed. e U-Type Belt
Cleaner operates at the discharge end of the conveyor and is in direct contact with the moving belt. Only visual
observations can be made while the belt is running. Service tasks can be done only with the conveyor stopped
and by observing the correct lockout/tagout procedures.
6.1 New Installation Inspection
Aer the new cleaner has run for a few days a visual inspection should be made to ensure the cleaner is
performing properly. Make adjustments as needed.
6.2 Routine Visual Inspection (every 2-4 weeks)
A visual inspection of the cleaner and belt should look for:
• If spring length is the correct length for optimal tensioning
• If spring gap is correct for optimal tensioning (for J-Bolt tensioners)
• If belt looks clean or if there are areas that are dirty
• If blade is worn out and needs to be replaced
• If there is damage to the blade or other cleaner components
• If fugitive material is built up on cleaner or in the transfer area
• If there is cover damage to the belt
• If there is vibration or bouncing of the cleaner on the belt
• If a snub pulley is used, a check should be made for material buildup on the pulley
• Signicant signs of carryback
•
• If any of the above conditions exist, a determination should be made on when the conveyor can
be stopped for cleaner maintenance.
6.3 Routine Physical Inspection (every 6-8 weeks)
When the conveyor is not in operation and properly locked and tagged out, a physical inspection of the
cleaner to perform the following tasks:
• Clean material buildup o of the cleaner blade and pole
• Closely inspect the blade for wear and any damage. Replace if needed.
• Ensure full blade to belt contact
• Inspect the cleaner pole for damage
• Inspect all fasteners for tightness and wear. Tighten or replace as needed.
• Replace any worn or damaged components
• Check the tension of the cleaner blade to the belt. Adjust the tension if necessary using the chart
on the cleaner or the one on Page 16. For J-bolt Tensioners, use the spring tension gauge to set a
.7mm (.030”) gap between spring coils.
• When maintenance tasks are completed, test run the conveyor to ensure the cleaner is
performing properly

1. Release the blade tension.
UST Spring Tensioner: Loosen the tension
adjusting nuts on the tensioner pivot rods,
allowing the pole to rotate the blade down
(Fig. 1a).
J-Bolt Tensioner: Loosen both J-bolt jam
nuts and remove the tensioner adjusting
nuts and at washers, allowing the pole to
rotate against the stop collar and the blade
to rotate down (Fig. 1b).
Double check the blade type needed for your application:
F- Blade - for mechanically-spliced belts
C-Blade - for Flexco Solid Plate mechanically spliced and
vulcanized belts
V-Blade - for vulcanized belts. Can be used with mechanical splices
(solid bolt fasteners) that are recessed (skived) into the belt cover
(bolts must be ground on plate fasteners)

3. Install the new blade.
a. Center the blade in the holder (Fig. 3).
b. Tighten all plate retaining screws.
c. Tighten blade retaining screws 8 turns and tighten the blade
retaining screw locknuts (Fig 3).
5. Inspect for full blade contact to the belt. Important - Always be
sure there is uniform contact between the blade and the belt. If the
blade is not in full contact with the belt at the edges and center, raise
or lower the pole position of the cleaner and reapply the tension (See
Installation Instructions).
Section 6 - Maintenance
2. Remove the worn blade.
a. Loosen both locknuts on the blade retaining screws. Turn blade retaining screws out 8 turns (Fig. 2a).
b. Loosen or remove all plate retaining screws.
c. From one end, insert a screwdriver under the blade and lightly pry the blade up and out of the blade
holder (Fig. 2b). Once the blade breaks free, pull it out by hand.
c. Remove the blade from the holder and clean material buildup from holder with a wire brush (Fig. 2c).

4. Reset the blade tension.
UST Spring Tensioner: Refer to the chart for the spring
length required for the belt width. Lightly pull the pivot
arm toward the end of the torque arm slot nearest the
pole and turn the adjusting nuts until the required
spring length is achieved (Fig. 4a). NOTE: e chart
is also on the cleaner’s pivot sha bracket for future
reference for retensioning maintenance. Reference
Section 4 (Cleaner Installation Instructions) on page 6.
J-Bolt Tensioner: Rotate the pole and insert the J bolts
through the J bolt mount holes and install the at
washers and tensioner adjusting nuts. Turn the tensioner
adjusting nuts until a .7mm (.030”) gap (use Spring
Tension Gauge included with cleaner) appears between
all coils of the tension spring (Fig. 4b). Lock both J bolt
jam nuts.
Test run the cleaner. Run the conveyor for at least 15 minutes and
inspect the cleaning performance. Check the spring length for proper
tensioning. Make adjustments as necessary.
