Introduction
This electric hoist EQS is designed and manufactured for the purpose to lift and lower a load within a normal
work environment.
The manual trolley is designed and manufactured for the purpose to move the lifted load laterally
with the combination with the electric hoist.
Movement of a load in a 3D direction such as up/down, forward/backward and right/left is also enabled by
combining with a crane.
This Owner's Manual is intended for those operating the KITO electric hoist EQS and maintenance engineers
(* pesonnel with expertise).
Other than this manual, Disassembly/Reassembly Manual is also available for the maintenance engineers.
Assign the maintenance engineers and use these materials for inspection and repair. Please contact the nearest
distributor or KITO for these materials.
* A person who has a thorough knowledge of the structure and rolls concerning Electric chain block and is
recognized as an expert by an entity.

•Carry out daily inspection by user.
•Carry out inspection (monthly, annual) by maintenance engineer.
•Keep the record of the inspection.
Failure to comply with these instructions causes bodily injury or loss of property.
■General Matters on Handling of Dual Speed VFD Model
The Dual Speed Variable-Frequency Driver (hereinafter referred to as "VFD") model is controlled by VFD for
important items related to safety such as operation, braking and emergency stop. Be sure to follow the safety
precautions below as well as the above safety precautions.
•Do not reassemble the Dual Speed VFD model to contactor type.
•Do not change parameters.
When parameters need to be changed, ask distributor or KITO.
•Do not carry out the work such as maintenance and inspection within 5 minutes after power off.
Wait for the completion of discharging of the capacitor inside the VFD and dual power converter (hereinafter referred
to as "DPC").
•Do not change the connection of the VFD and DPC.
When the wires were removed for any reason, connect them again correctly checking the wiring diagram inside the
controller cover.
•Do not carry out withstand voltage test and insulation resistance measurement of a circuit by megger while
the VFD is connected.
•Do not turn off the power while operating.
•Never turn off the power when a load is suspended.
Never, under any circumstances, turn off the power when a load is suspended. Doing so will cause the load to be
slightly lowered after the power is turned on again due to control system initial preparation.
Failure to comply with these instructions may result in death or serious injury and the damage of VFD and DPC.
Prohibited
DANGER
Mandatory
•USE KITO genuine VFD and DPC.
The VFD and DPC requires the special specification for KITO. Be sure to use genuine VFD and DPC.
Failure to comply with this instruction may result in death or serious injury.

How to Use
•Do not use the Hook without a Hook Latch or damaged Hook.
•Do not use the Load Chain with heavy elongation, abrasion or deformation.
•Do not cut, extend, or weld the Load Chain.
•Do not use the Load Chain with the Bottom Hook without smooth motion.
•Do not use the Load Chain when its brake does not function securely even without load, or when the stopping
distance is too long.
•Do not use the product if it moves oppositely to the direction indicated on the push button switch.
Failure to comply with these instructions may result in death or serious injury.
•Carry out daily inspection before operation.
(When any abnormality was found during inspection, turn off the power, indicate “FAILURE" and ask the maintenance
engineer for repair.)
•Check the slinging devices for no abnormality.
Failure to comply with these instructions may result in death or serious injury.
Mandatory
CAUTION
KITO Model EQS Electric Chain Hoist is a dual speed VFD and a single speed model. For the three phase power Single
speed model, such products are provided that can travel/traverse when combined with a trolley or a crane. Their push
button switches for operation differ in the size and the operating method. Check the product model of the hoist and use it
properly.
Prohibited
•Do not use the product with an illegible nameplate or warning label affixed to the body size.
•Do not install a chain above the specified lifting height.
Failure to this instruction may result in the injury or the property damage.
•When using the product for the first time, affix the labels indicating East, West, North and South on the push
button switches.
•Check the contents of the work and make sure that the electric chain hoist has proper performance for the load
and lift.
•Check the contents of the work and operate the electric chain hoist at a place enabling to look out the operating
area without hindrance.
•When looking out the operating area is difficult, arrange the monitor near the place for safety.
•Operate the electric chain hoist at a place with firm foothold without danger of falling, stumbling, slipping or over
turning.
•Before moving the load, warn all the surrounding people.
•Even if the crane or the electric chain hoist is permanently installed and used for the same purpose repeatedly,
check the contents of the work and make sure that the work does not exceed the capacity on each occasion.
•Appoint the maintenance engineer or competent personnel among the qualified personnel for operation of
cranes and electric chain hoists. Indicate the name of the personnel on a place with legibility.
•The maintenance engineers shall check the result of daily inspection.
•When informed of abnormality of the electric chain hoist, the maintenance engineers shall take immediately any
necessary measures such as prohibition of use and repair.
•When carrying out inspection and repair, secure the environment for safe work without electric shock and falling.
Failure to comply with these instructions may result in bodily injury or property damage.
