Storage and transportation

Danger: Do not move the belt by rolling it. This could cause serious injury or even death if someone is caught beneath the belt.

Warning: Keep the belt clear of open flames. To avoid the risk of fire, do not store near heat sources or devices producing electric sparks, such as stoves, and avoid storage near steam, oil and chemicals.

Warning: When lifting the belt, use cranes and hoists that match the weight of the belt.

Caution: Store the belt at temperatures between -10 and 40°C, with low humidity levels, and avoid direct exposure to sunlight, wind and rain.

Caution: Use a stopper under the belt so that it does not roll or tip over in storage.

Caution: Do not store or transport the belt on its side, in a leaning position, or in a distorted state.

Caution: Use a protective cover when lifting the belt to protect the belt edges.

Routine inspection

Routinely inspect the belt before use, and take corrective action when needed. Contact your dealer if abnormalities continue after taking corrective action.

Inspection items	Remedial actions
1. Belt body damage or wear	Repair or replace
2. Belt joint separation or damage	Repair
3. Defective roller rotation	Servicing or replace
4. Accretion on pulley or rollers	Remove accretion
5. Take-up device operation abnormality	Servicing
6. Skirt or belt cleaner abnormality	Servicing
7. Abnormality in the chute	Servicing
8. Foreign object adherence	Remove foreign object(s)

* Never touch a moving belt. It is only safe to inspect a belt after it has come to a complete stop.

During operation

Danger: Install safety barriers and covers to prevent any type of body contact with the belt.

Danger: Do not enter areas behind safety barriers while the belt is in operation.

Danger: Do not wear a necktie or items that may dangle from clothing. These items could be drawn into the belt operation.

Danger:: Keep your hands and body off of the belt surface.

Warning: Do not place foreign objects on the belt, particularly cigarette butts which may cause a fire.

Caution: Check control panel switches and emergency stop device before operating the belt, and know the location of emergency exits.

Caution: Comply with maximum load (weight) limitations to prevent abnormal tension, which can cause malfunction.

Caution: Place loads so that they do not fall from the conveyor.

Caution: Install devices to detect or prevent abnormal operation, such as a reverse running prevention device, belt tracking detector, emergency shut-off device, etc.

Caution: If you detect trouble needing maintenance, such as an abnormal sound or belt tracking, stop the belt immediately and conduct an inspection.

Caution: Do not walk under the belt or enter the area under the take-up device.

Caution: Do not remove or dispose of build-up while the belt is in operation.

While belt is stopped

Danger: Turn the operating switch off and hang a tag on it indicating that the belt is "Not in operation."

Danger: Do not get on the belt or walk on it unless necessary for repairs.

Danger: Do not stop the belt with hot items still on it, as there is a danger of fire.

Danger: Confirm that the entire length of the belt is safe before re-starting operations.

Caution: Do not wear spiked shoes if you must get on the belt for repairs.

Caution: Do not allow oil, chemicals, welding sparks, or heavy or foreign objects to fall on or adhere to the belt and cause damage.

Performance considerations

Warning:

Do not use the belt outside the ranges listed in the catalog.

Examples

(1) Belt performance: cover rubber performance, belt strength, adhesion performance, etc.
(2) Design conditions: safety factors, pulley diameters, etc.
(3) Use conditions: appropriate properties of items transported, etc.

Caution: Do not transport items having temperatures above the allowable ranges on heat-resistant belts.
Heat-resistant belts are not resistant to flames.

Caution: Flame-resistant belt performance complies with JIS K6324, but may ignite depending on operating conditions.

Caution: Do not use ordinary belts for special applications requiring heat resistance, oil resistance or flame resistance.
(Cover rubber performance in accordance with JIS K6322.)

Caution: Use Bando Sunline Belts for the conveyance of unpackaged foods, or in applications where rubber may come into contact with food.

Belt joints

Danger: Open flames are prohibited at worksites to prevent the risk of fire.

Warning: During the splicing process, do not allow exposure to direct sunlight, water or dust to prevent a lowering of adhesive strength.

Warning: Ensure adequate ventilation when using rubber cement or solvents as they may pose a health risk.

Warning: Do not leave rubber cement or solvents at the worksite as they cause fire.

Caution: Follow manufacturer-recommended procedures when splicing belts.

Caution: Use only manufacturer-specified materials when splicing belts. Also, do not use bonding materials beyond their expiration date.
