Section 2 – Safety Considerations and Precautions
Before installing and operating the MHCP Precleaner, it is important to review and understand the following safety information.
There are set-up, maintenance and operational activities involving both stationary and operating conveyors. Each case has a safety
protocol.
2.1 Stationary Conveyors
The following activities are performed on stationary conveyors:
• Installation • Blade replacement • Repairs
• Tension adjustments • Cleaning
!
DANGER
!
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
2.2 Operating Conveyors
There are two routine tasks that must be performed while the conveyor is running:
• Inspection of the cleaning performance
• Dynamic troubleshooting
DANGER
!
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.
!
WARNING
Every belt cleaner is an in-running nip hazard. Never
touch or prod an operating cleaner. Cleaner hazards cause
instantaneous amputation and entrapment.
!
WARNING
Belt cleaners can become projectile hazards. Stay as far from
the cleaner as practical and use safety eyewear and headgear.
Missiles can inflict serious injury.
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.

Section 3 – Pre-Installation Checks and Options
3.1 Checklist
• 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
- Are there obstructions that may require cleaner location adjustments
(see 3.2 – Cleaner Location Adjustments)
- Is the install on an open head pulley requiring mounting structure
(see 3.3 – Optional Installation Accessories)

Section 3 – Pre-Installation Checks and Options
3.2 Cleaner Location Adjustments
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: 36"
X = 18"
Y = 14 3/8"
C = 23"
1. Determine the given location dimensions and define the change needed. After laying out the given X & Y dimensions,
determine the distance of the modification required for adequate clearance of the pole and tensioning system. (In the example
we decide to lower the pole 2" to clear the support structure).
36”
2. Write down known dimensions. We can now determine two of the three required dimension which will allow us to find 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 2", so we add 2" to the given “Y” dimension.
X = ?"
Y =14 3/8+2=16 3/8"
C = 23"
3. Determine final dimension. On a flat 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
Y (16 3/8")
tape measure starting at the modified “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 = 16 1/8"
Y = 16 3/8"
Fig. 3a
C (23")

This distance is the new
“X” dimension

(Adjustments can be made to the X & Y coordinates to move away
from obstacles as long as the C dimension remains constant.)
