Section 2 - Safety Considerations and Precautions
Before installing and operating the RBP1 Belt Positioner it is important to review and understand the following safety
information.
ere are setup, 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 • Impact bar replacement • Repairs
• Skirt rubber adjustments • Cleaning
!
DANGER
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 impact
bed 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
!
WARNING
Use Personal Protective Equipment (PPE):
• Safety eyewear
• Hardhats
• Safety footwear
Close quarters 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
components. 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 sealing performance
• Dynamic troubleshooting
!
DANGER
!
WARNING
Every belt conveyor is an in-running nip hazard.
Never touch or prod an operating impact bed.
Conveyor hazards cause instantaneous amputation
and entrapment.
!
WARNING
Conveyor chutes contain projectile hazards. Stay as far
from the trainer as practical and use safety eyewear and
headgear. Missiles can inict serious injury.
4RBP1 Belt Positioner
Never adjust anything on an operating impact
bed. Unforseeable materials falling into the chute
can cause violent movements of the impact bed
structure. Flailing hardware can cause serious
injury or death.

Section 3 - Pre-installation Checks and Options
3.1 Checklist
• Check the model and size of the belt trainer. Is it the right one for your beltline?
• Check the RBP1 Belt Positioner to be sure all the parts are included in the shipment.
• Find the Information Packet in the shipment.
• Review the “Tools Needed” section on the front of the installation instructions.
• Prepare the conveyor site:
- Identify the point(s) of mistracking, expecting 50' (15M) of downstream and upstream inuence.
- Position the unit in the center of the mistracking.
- Optimal location: No closer than 3' (.9M) and no further than 6' (1.8M) from a return roller.
- Remove old tracking devices.
3.2 Optional Installation Accessories
Optional tools can make the installation of the RBP1 Belt Positioner easier and faster.
e Flexco Flex-Lier makes the job of liing the
conveyor belt easy and safe. Using two Flex-Liers,
the belt can be quickly lied out of the way to install
the PT Smart™. e Flex-Lier has the highest safe li
rating available at 4000 lbs. (1810 kg) for Medium and
Large, 6000 lbs. (2750 kg) for XL. And it’s versatile.
It can also be used to li topside or return side belt
for splicing, roller replacement or other maintenance
jobs. Available in three sizes: Medium for belt widths
36" - 60" (900 - 1500mm), Large for belt widths 48" 72" (1200 - 1800mm), and XL for belt widths 72" - 96"
(1800 - 2400mm).

Locating the Positioner
• Look at the belt on the return side and identify where the belt is mistracking.
• Locate the Positioner in the center of the problem area.
• Generally, if the belt is correctly positioned at the tail pulley (A) so the belt is
center loaded, it will run straight on the top side.
• Another problem area may be at the counter-weight pulley (B and C).

later use
1. Reposition mounting brackets (Fig. 1). Remove the
mounting brackets from the inner shipping position,
move them down toward the rollers, and remount them
on the outside of the frames. Remove the mounting
bolts, lock washers and nuts from the brackets and set
them aside for Step 4.
2. Determine Positioner location on the belt (in the
selected location). Measure an equal distance from a
common point on both sides of the structure and mark
both sides at the measured points (Fig. 2). e unit must
be square to the conveyor.
NOTE: e Positioner should be centered between
two standard return rollers. For general applications-standard belts up to 72" (1800mm): position the unit no
closer than 3' (.9M) to a return roller and no farther than
6' (1.8M).

3. Adjust unit for conveyor width.
a. Measure the structure’s inside width from side to side.
b. Loosen the four jam nuts and set screws on the frames
and slide the unit apart to the same dimension as the inside
structure width measurement minus 1/2" (13mm) to ensure
an easy t. Retighten set screws and jam nuts (Fig. 3).
NOTE: e inner tubes between the two frames should be
kept centered to ensure both sides have maximum support.
Center marks on the inner tubes make it easy to see that
the tubes are centered.
4. Mount unit on the conveyor.
Align the unit with the location marks on the structure.
NOTE: Check the slot adjustment range of the frame and
the mounting bracket (Fig. 4). If there is not 4" to 6" of slot
visible, turn the mounting brackets upside down for more slot
adjustment. Clamp or hold the unit in place, drill mounting
bolt holes on each side and secure with mounting bolts, lock
washers and nuts, or weld in place.

5. Adjust Positioner to the belt.
Loosen the two frame adjustment bolts on the side the belt is
running o and apply pressures as follows (Fig. 5):
a. Push down on unit until roller contacts 6" to 8" (150 to
200mm) of the belt. e roller on the other side should be set
to contact the belt 4" (100mm) or less. Tighten all nuts.
b. Allow the conveyor to run a minimum of ve revolutions
and evaluate the results.
IMPORTANT: If more correction is needed, increase the
roller-to-belt contact pressure on the side running o; if
necessary, decrease contact pressure on the opposite side.
MAINTENANCE
e rollers on the Positioner are sealed for life.

Section 5 - Pre-Operation Checklist and Testing
5.1 Pre-Op Checklist
• Recheck that all fasteners are tight
• Apply all supplied labels
• Be sure that all installation materials and tools have been removed from the belt and conveyor area
5.2 Test Run the Conveyor
• Run the conveyor for at least 15 minutes and conrm the belt is tracking properly.
• If belt is still mistracking too far to one side, increase the roller-to-belt contact pressure on the side
running o; if necessary, decrease contact pressure on the opposite side.

Section 6 - Maintenance
Flexco belt trainers are designed to operate with minimum maintenance. However, to maintain superior performance
some service is required. When the trainer is installed a regular maintenance program should be set up. is program
will ensure that the trainer operates at optimal eciency, and problems can be identied and xed before any damage
is done to the belt, the trainer, other conveyor components, or structure.
All safety procedures for inspection of equipment (stationary or operating) must be observed. e RBP1 Belt
Positioner 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 RBP1 Belt Positioner has run for 15 minutes a visual inspection should be made to ensure the trainer
is performing properly. Make adjustments as needed.
6.2 Routine Visual Inspection (every 2-4 weeks)
A visual inspection of the RBP1 Belt Positioner can determine:
• If the belt is tracking as required
• If the main frame is free of material and rolling properly
• If there is damage to the main frame or other components
• If the rollers are turning freely and without damage
If any of the above conditions exist, a determination should be made on when the conveyor can be
stopped for trainer 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 trainer
to perform the following tasks:
• Clean material buildup o the trainer and components.
• Closely inspect main roller for free movement and wear. Replace if needed.
• Closely inspect complete unit for damage.
• Inspect all fasteners for tightness and wear. Tighten or replace if needed.
• When maintenance tasks are completed, test run the conveyor to ensure the trainer is
performing properly.
