Section 2 – Safety Considerations and Precautions
Before installing and operating the H-Type® Precleaner with XF2-Tips, 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
- Is the install on an open head pulley requiring mounting structure
- Are there obstructions that may require cleaner location adjustments

Section 3 - Pre-Installation Checks and Options (cont.)
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: 900mm
X = 322mm
900mm
Y = 482mm
C = 580mm
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 50mm to clear the support structure).
X
C
Y
2. Write down known dimensions. We can now determine two of the three required dimensions 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 50mm, so we add 50mm to the given “Y” dimension.
X = ?"
Y = 482mm + 50mm = 532mm
C = 580mm
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 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 = 231mm
Y = 532mm
C = 580mm
This distance is
new “X” dimension

Y (532mm)

1. Find X, Y & C measurements. Find the X and Y measurement
specifications for the pulley diameter. See charts on page 8. The pulley
diameter measurement should include lagging and belt.
Pulley Diameter ________"; X=________"; Y=________"; C=________".
Using the correct X and Y coordinates will position the cleaner blades at
15° below the horizontal plane on the head pulley.
2. Measure head pulley shaft.
Determine the diameter of the pulley shaft
and divide by 2. ________"
3. Locate horizontal line from center of pulley shaft.
the pulley shaft and draw a horizontal line A. Measure down from Line
A half the diameter of the pulley shaft and draw Line B parallel from the
pulley shaft (Fig. 1).
4. Mark X dimension.
Subtract the above dimension (Step 2) from the
selected X dimension to establish the modified X dimension. With this
new X dimension measure horizontally from the front of the pulley shaft
forward on Line B and mark on the chute (Fig. 2).

5. Determine Y dimension.
From the X mark, draw a line vertically down to the
selected Y dimension and make a mark (Fig. 3). This is the correct position for the
X
Y
center of the pole.
6. Locate offset bracket position. To locate the position of the offset bracket, position
offset bracket template with the large hole notches aligned with the layout lines on
the chute wall (Fig. 4). The template can be used with the bracket holes either below
or above the Y mark.
7. Cut pole opening. Using template provided, trace and cut the large opening and the
mounting holes.
8. Install offset brackets. Locate the offset brackets in the correct
position on the chute wall and bolt or weld in place (Fig. 5).

9. Install the pole. Slide the pole across the pulley and through the
chute openings. Allow the tips to hang down.

12. Center the cleaner on the belt and lock in place. Center the tips on the
belt and install a pole lock collar on one end of the pole. Slide the collar
snugly up to the mounting plate and tighten.
13. Install the QMT spring tensioner.
Remove the adjusting nuts, bushings
and spring from the pivot rod. Insert the pivot arm through the slot in the
torque arm. Slide the torque arm onto the pole end (be sure the rotation
of the arm is correct to tension the blade) and rotate it until the pivot shaft
bracket lines up with the desired bolt holes (Fig. 7). Remove bolts, nuts and
washers from mounting plate and reinsert through the pivot shaft bracket
and mounting plate.
