Section 2 – Safety Considerations and Precautions

Before installing and operating the EZP1T 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

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

There 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 inflict serious injury.

3.1 Checklist

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

· Are there obstructions that may require cleaner location adjustments

(see 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: 12" (300 mm)

X = 6 1/8" (154 mm)

Y = 5 1/2" (138 mm)

C = 8 1/4" (206 mm)

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" (50mm) to clear the support structure).

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 2" (50mm), so we add 2" (50mm) to the given“Y” dimension.

X = ?"

Y = 5 1/2 + 2 = 7 1/2" (138 + 50 = 188 mm)

C = 8 1/4" (206 mm)

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 = 3 1/2" (88 mm)

Y = 7 1/2" (188 mm)

C = 8 1/4" (206mm)

Section 4 – Installation Instructions

Physically lock out and tag the conveyor at the power source

before you begin cleaner installation.

Installation specs and instructions are based on

the assumption that the conveyor is in its working

position (angle). If the conveyor angle will be

different, the cleaner should be installed per the final

position. Call 91-44-6551-7771 if you need help on

determining the proper coordinates.

1. Locate the correct pole position. Measure and determine Dimension

A (see instructions above). Find Dimension A on the Pole Location

Chart at right and determine Dimensions X,Y and C. Measure out

horizontally from the center of the pulley shaft Dim X and mark. From

that mark, draw a long vertical line down,then measure and mark Dim

Y. This indicates the location of the center of the cleaner pole. Measure

and mark both sides. NOTE: If the location is obstructed,use Dim. C

and move on an arc from the center of the pulley shaft to find an open

position.Dim. C must remain constant to correctly locate the pole (see

drawing above). NOTE: For open head installs, first add mounting

support materials to the structure.

2. Mark and cut the mounting plate

holes. Using the mounting plate

template provided in the instruction

packet, position the large pole

access hole on the chute, aligning

the hole notches with the layout

lines. Position the keyway toward

the pulley. Trace the pole cutout and

mounting holes (Fig. 1). Cut the

holes on both sides of the chute.

NOTE: Hole cutouts are slotted for later adjustment if needed.

Section 4 – Installation Instructions (cont.)

3. Install the mounting plates. Bolt flat mounting plate (with

keyhole) to the side opposite where the tensioner will be

mounted. Keyhole should face the pulley (Fig. 2). Install torsion

mounting plate (with circular weldment) to the tensioner side.

Center plates on the slotted holes and tighten bolts.

4. Install the pole. Remove both blade pins and blade from the

pole (Fig. 3a) and insert the pole in through the mounting

plates (starting with keyhole plate) (Fig. 3b).

5. Center pole to the belt (Fig. 4a). Mark pole 3/4" (75mm)

outside torsion mounting plate (Fig. 4b).Feed pole further

through torsion mounting plate so pole can be cut on the mark

(slide pole away from UHMW bearing at least 6" before cutting

to prevent melting.) After cut is made, grind end of pole clean

from rough edges (Fig. 4c).

6. Reinstall blade. Reinstall blade with both blade pins.Center

the blade on the belt. Rotate the blade up to the belt and check

to insure that the blade is square to the pulley face (Fig. 5a). If

not,loosen a mounting plate on one side and adjust the plate

forward or backward to square the blade to the pulley, and

retighten the bolts (Fig.5b).

7. Install the tensioner. Slide torsion spring assembly into cut

end of pole until fully engaged with the pole (Fig. 6a). Hold

blade against pulley and rotate indicator mark until it is vertical.

Tighten set screws with 1/4" (6mm) allen wrench (Fig.6b).

9. Set the blade tension. While

holding the blade to the belt,

place cap over spring. Use

wrench on center hex shaft to

apply tension to spring at desired

angle (see chart).While holding

tension with wrench,tighten the

two set screws (Fig. 8).

8. Lock pole with collar. Ensure pole is flush (no space) on tensioner side.

Install and tighten pole lock collar on non-tensioned side (Fig. 7).

10. Confirm correct pole location. After the cleaner is installed, slide the Pole Location Gauge (provided in the

instruction packet) between the cleaner pole and the pulley, until it stops at a step (Fig. 9a). Read the flat area

where the pole is resting (Fig. 9b.) This diameter should be equal to Dim A used in Step 1.

NOTE: If the diameter reading on the Pole Location Gauge does not read the same as in Step 1, check the“C”

dimension and correct accordingly.

Test run the cleaner and inspect the performance. If vibration occurs or more cleaning efficiency is desired,make

the necessary tensioning adjustments.
