□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!

■WARNING LABELS etc. AND ATTACHMENT POSITIONS
For standard machines, warning labels etc. and their attachment positions are as follows:
1. WARNING LABELS
Label classification
Label
Instruction
■ALWAYS CONNECT TO EARTH
Ensure the conveyor is connected to earth at all
times to prevent electric shock.
■DISCONNECT POWER BEFORE SERVICING
Ensure that the power is switched off when carrying out
relocation, inspection, cleaning, etc. of the conveyor,
otherwise there is a risk that conveyor may start
unexpectedly.

1. Place conveyor frame upside down on table. (Assembly is easier this way.)
2. Install control unit delivered in separate packaging. → See p.12. (For constant-speed type using 200V
2. three-phase power source, controller is optional.)
3. If return rollers are delivered in separate packaging, stickers RETURN ROLLER FIXING POSITION are
2. affixed on side of frame. Return roller attachment tap pieces are temporarily bolted into frame
2. underside slots, just under the stickers. Install return rollers using the tap pieces as shown in figures
2. below. (Return rollers are individually packed and temporarily attached beside drive unit.)
NOTE: 1. For center drive type of 2m or less in length, machine has no return roller.
2. In the following cases, return rollers are delivered already installed as shown in fig. 1, i.e.
installation is unnecessary.
-3m or less in machine length and 60mm in frame depth
-3m or less in machine length, 30mm in frame depth and 300mm or less in belt width
3-1. INSTALLING STANDS AND RETURN ROLLERS
3
ASSEMBLY
Installation will become easier by inserting
and tightening bolt into end of tap piece.
4. Stands(optional) are delivered in separate packaging. Install them using the attached stand tap pieces.
NOTE: 1. Install each stand in appropriate position referring to “Standard Installation Positions of
NOTE: 1. Stands”, p.9.
NOTE: 2. For machine length of 1.2m or less, stand tap pieces are delivered inserted into conveyor frame.
5. When assembly is completed, turn over the entire conveyor and place on the floor.
6. Adjust conveyor height following “Stand Height Adjustment”on next page. Confirm full
6. length of frame is straight and level on top, and firmly tighten stand bolts and nuts.

■Standard Installation Positions of Stands
Considering frame depth and strength, installation positions of stands are determined as follows.
Unit：mm
When conveyor exceeds 3m in length, it is delivered packed as shown below. Assemble conveyor
following the procedures in the tables. (*Return rollers are individually packed and temporarily attached
beside drive unit.)
3-2. ASSEMBLING LONGER MACHINES
PACKAGING
Machine length: 3.01-6.0m Divided into 2 sections
Belt width of 300mm or less: 1 package
Belt width of 350mm or more: 2 packages
■Stand Height Adjustment
NOTE: When adjusting stand heights, take care not to pinch fingers. To prevent conveyor main body
NOTE: from rapidlygoing down, loosen fixing bolts little by little while supporting conveyor with the other
NOTE: hand.
Before starting adjustment, ensure tapered grooves(*1, *2)
and fixing bolts(*3, *4) are positioned correctly as shown
in figure, right. To lower stand upper post(*5), loosen
fixing bolt(*3). If tapered groove(*1) entirely goes down
into stand lower post(*6) while lowering upper post(*5),
tighten fixing bolt(*4) into tapered groove(*2). For more
adjustment, loosen fixing bolt(*4) again. Once adjustment
is completed, tighten fixing bolts(*3, *4). To finely adjust
conveyor level, use level adjusters beneath stand.
NOTE: For belt top height of 550mm or less, stand does
NOTE: not have tapered groove(*2).
