1.1 General Introduction

Section 2 - Safety Considerations and Precautions
Before installing and operating the MMP Precleaner, 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 3 - Pre-installation Checks and Options
• Check that the cleaner size is correct for the beltline width
• Check the belt cleaner carton and make sure all the parts are included
• Review the “Tools Needed” list on the top of the installation instructions
• Check the conveyor site:
- Will the cleaner be installed on a chute
- Is the install on an open head pulley requiring mounting structure
(see 3.3 - Optional Installation Accessories)
- Are there obstructions that may require cleaner location
adjustments (see 3.2 - Cleaner Location Adjustments)
3.1 Checklist
7
In certain applications it is necessary to modify the location of the precleaner pole due to permanent
obstacles that obstruct the desired location. Relocating the pole location can be done easily and does not
hinder the performance of the cleaner as long as the “C” dimension is maintained.
NOTE: In the following example we will be lowering the pole location in the “Y” direction, but the same
method could also be applied in the “X” direction.
Conveyor situation:
Pulley Diameter: 610mm (24")
X = 321mm (12 5/8")
Y = 305mm (12")
C = 441mm (17 3/8")
1. Determine the given location dimensions and define the change needed. Aer laying out the given X &
Y dimensions, determine the distance of the modication required for adequate clearance of the pole and
tensioning system. (In the example we decide to lower the pole 50mm (2") to clear the support structure).
2. Write down known dimensions. We can now determine two of the three required dimension which will
allow us to nd the third. We know we cannot alter the “C” dimension, so this will remain the same. Also
we are required to lower the unit in the “Y” dimension 50mm (2"), so we add 50mm (2") to the given “Y”
dimension.
X = ?"
Y = 306 + 50 = 356mm (12 + 2 = 14")
C = 441mm (17 3/8")
3. Determine final dimension. On a at vertical surface, using a level, draw one horizontal line and one
vertical line creating a right triangle (Fig 3a). Measure down from the intersection the determined “Y”
dimension and mark (Fig 3b). With the tape measure starting at the modied “Y” mark, swing the tape
across the “X” line and mark at the “C” dimension where it crosses the “X” line (Fig 3c). Measure from the
intersection to the “C” intersection and this will be your new “X” dimension (Fig. 3d).
X = 260mm (10 1/4")
Y = 356mm (14")
C = 441mm (17 3/8")

3.4 Correct Blade Installation and Tensioning
For optimal cleaning eciency and long wear life, the TuShear™ blade must be located and tensioned correctly on
the belt head pulley. 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.
Incorrect:
no gap
Correct Tension:
Full contact
between blade
face and belt
Fig. 4
Tip pushed away
from belt
Incorrect:
Larger than
3mm
(1/8") gap
Fig. 2 Fig. 3
Correct Tensioning:
e blade should be tensioned until the gap is gone (Fig. 4).
Possible Problems:
• Pole location too far out - e initial blade/belt
contact gap will be larger than 3mm (1/8") (Fig. 2).
If the blade is correctly tensioned it may ip through
before it is fully worn. If tensioned too lightly, it
will develop the “smile eect” quickly and not clean
prop e r l y.
• Pole location too far in - If there is no gap at the initial
blade/belt contact (Fig. 3), the tip of the blade may not
be touching the belt. In this case, the blade will push
away and lose its shearing (cleaning) eect. e blade
may also develop a ap at the tip which may trap
material.
Correct Location:
When blade contact is made against the head pulley (prior to tensioning) there
should be a 1.6mm (1/16") to 3mm (1/8") gap at the bottom of the blade
face (Fig. 1).
For optimal cleaning and reduced blade retensioning, the cleaner blade width should be sized to t the material
path of the belt. e material path is typically the center 2/3 of the belt width. Choosing a blade only slightly wider
than the material path can decrease dierential blade wear which reduces blade retensioning maintenance, as well
as reducing the frequency of blade replacement.
