2.2. General Safety Information
Read and understand all safety instructions, safety decals, and manuals and follow them when operating or
maintaining the equipment.
• Owners must give instructions and review the information initially and annually with
all personnel before allowing them in the work area. Untrained users/operators
expose themselves and bystanders to possible serious injury or death.
• Use for intended purposes only.
• Modification of the conveyor in any way without written permission from the manufacturer is not covered
by the warranty.
• Follow a health and safety program for your worksite. Contact your local occupational health and safety
organization for information.
• Follow applicable local codes and regulations.
2.3. Chain Conveyor Safety
• Keep body, hair, and clothing away from moving chain
conveyor.
• Do not climb, sit, stand or walk on conveyor at any time.
• Lock out power before removing cover(s).
• Shut off and remove key or lock out power source before
inspecting or servicing the chain conveyor.

2.4. Torque Arm Safety
Bucket Elevator gear reducers may be equipped with backstops
and torque arms / swing base. Never remove the torque arm /
swing base when the bucket elevator is loaded. Removal of the
torque arm / swing base may cause the reducer to suddenly
rotate resulting in serious injury or death.
2.5. Rotating Parts Safety
• Keep body, hair, and clothing away from rotating parts.
• Do not operate with any guard removed or modified. Keep
guards in good working order.
• Shut off and lock out power source before inspecting or
servicing machine.
2.6. Combustible Dust
The conveyor has been designed for safe use in areas where hazards due to combustible dust
may potentially occur. Help reduce the risk of a dust explosion by following the preventive
measures below.
Control the dust:
• Clean grain to reduce fines.
• Use equipment to minimize breakage.
• Use a filtering system to capture dust.
• Use an air system to reduce dust.
• Spray edible mineral oil on the grain to reduce air-born dust when handling.
• Paint equipment that is in the interior of a facility with a coating that is slick, not allowing dust to accumulate.
• Clean up dust deposits after equipment operation.
• Enclose all equipment to keep dust from escaping.
Control the ignition source:
• Where applicable, use an electric motor rated for the dust classification area.
• Do not smoke in any potentially hazardous area.
• Use only explosion-proof lights and electric tools.
• Do not use anything around or inside the equipment that may produce a flame or sparks unless the air and
equipment are free of dust. For example: Do not use a match/lighter, grinder, or power saw. Use brush-less
electrical tools and explosion proof flash lights.
• Where possible, keep the work area wet such that dust cannot be dispersed in the air and smoldering
processes from sparks cannot develop.
• Follow the maintenance schedule to keep equipment operating properly at low temperatures.

• Purchase replacement parts from the manufacturer or authorized dealer/distributor. Original manufacturers
parts are designed with explosion proof features where applicable.
2.7. Ladder Safety
• Do not climb ladder if damaged, wet, icy, greasy, or slippery.
• Remove slippery materials on platforms, rungs and gripping
surfaces.
• Maintain good balance by having at least three points of
contact at all times.
• Use a fall restraint and arrest system when required. Consult
your local health and safety organization.
2.8. Fall Protection System Safety
• Ensure that the personal fall protection equipment meet the requirements of the
applicable national and local codes.
• Follow all safety and user instructions provided by the personal fall protection equipment
manufacturer during installation and use of this system.
• All users must be trained thoroughly in the safe use and limitations of the personal fall
protection equipment. Misuse of this system could result in serious injury or death.
• Ensure that the fall protection system is inspected, tested and maintained in accordance
with the manufacturer’s recommendations.
• Inspect components before each use for wear, damage and other deterioration.
• If the fall protection system has been subjected to a fall arrest or impact force, all
equipment used to arrest fall must be inspected and approved by the manufacturer or by
a competent and/or qualified person prior to being used again. If any damage is detected,
replace the equipment before resuming use.
• If a fall event should occur, immediately call emergency responders.
2.9. Platform Safety
• Check the platform working load. Do not overload. Contact AGI before adding any equipment to a platform.
• Close platform access door before and after working on the platform.

source and follow lockout and tagout procedures to prevent inadvertent start-up and
hazardous energy release. Know the procedure(s) that applies to your equipment from the
following power source(s). Ensure that only 1 key exists for each assigned lock, and that
you are the only one that holds that key. Ensure that all personnel are clear before turning
on power to equipment.
