□When using in a high or inclined position:
FOR YOUR SAFE USAGE
CAUTION : Improper handling of the conveyor may result in physical injury or damage!
■Transport and assembly
When transporting and assembling the conveyor, pay special attention not to drop it in order to
avoid physical injury or damage. When lifting by crane, pay attention to the balance of the conveyor.
■Earth and leakage breaker
Ensure the conveyor is connected to earth at all times to prevent electric shock. Also ensure that
an earth leakage breaker is connected to the power supply.
A. Prior To Use
■Emergency stop
Install an emergency stop device to immediately stop the conveyor in emergency.
■Start alarm
If it is not possible to supervise the operation of the full length of the conveyor from the operating
position, install a start alarm for increased safety.
■Keep the conveyor dry at all times
Do NOT use the conveyor in wet or humid areas. Do NOT splash liquids onto the conveyor. Do
NOT use or leave the conveyor outdoors. The machine is not waterproof. Do NOT touch electrical
parts with wet hands.
■Do NOT use in an explosive atmosphere
(Avoid explosive gas, explosive dust, etc.)
■Lower cover and guard
Install the optional lower cover or guard in order to prevent entry under the conveyor.
■Guide rail, top and side covers
To prevent objects from falling off the conveyor, install the optional guide rail, top and/or side
covers.
■Braking system
When using the conveyor on an incline, it is recommended that an optional braking system be
installed, in order to prevent reverse or other incorrect running of the conveyor.
■Environmental conditions
Ambient temperature
Ambient humidity
Atmosphere
Elevation
NOTE：
●Using the conveyor in a strong electric field (eg near broadcasting devices or high- frequency welding
machinery/equipment) could cause the conveyor to malfunction. In this case, install the conveyor at a
sufficient distance. Alternatively shield completely to avoid any interference with the conveyor.
●Using an inverter to this machine could cause other machines to get effects of high-frequency. In this
case, install the conveyor at a sufficient distance or shield completely.

B. During Operation
C. After Use
WARNING：Improper handling of the conveyor could result in serious physical injury or damage!
■Do NOT touch the conveyor when it is running
There is considerable risk of being caught and injured by the conveyor.
■Do NOT ride on or climb on the conveyor／Do NOT go under the conveyor
There is considerable risk of falling or being caught and injured by the conveyor.
■Beware of entanglement
When working close to the conveyor, take care not to get caught in the conveyor. There is
considerable risk of being injured by the conveyor.
■Do NOT remove safety covers
There is a risk of getting caught in the rotating parts such as pulleys. Only remove in case of
maintenance or inspection.
CAUTION：Improper handling of the conveyor may result in physical injury or damage!
■Do NOT apply force to ends of conveyor
Do NOT press down on, or hang off the sides of the conveyor. Injury may result from a toppling
conveyor.
■Secure the conveyor to the floor/ground
When using the conveyor, be sure to secure it to the floor/ground with anchor bolts etc. to
prevent it from toppling irrespective of indoor use or outdoor use.
■Switch off the power after use
Ensure that the power is switched off when carrying out relocation, inspection, cleaning, etc. of
the conveyor, otherwise there is a risk that the conveyor could start unexpectedly. When leaving
the conveyor unused for a long period, take plug out of the outlet /connector to prevent electric
shock or leakage.
NOTE：1. Always use in accordance with the Occupational Safety and Health Act.
2. If the owner modifies the conveyor, any ill effects will fall outside the conditions of the guarantee.
■Do NOT start the conveyor while it is loaded
The motor may become damaged due to overload. Additionally, the motors of variable-speed type
machines may burn out as a result of running at excessively low speeds for
long periods. Use the conveyor within the specifications, indicated in the instructions for use, and
in the catalogue.
CAUTION：Improper handling of the conveyor may result in physical injury or damage!
