hook attaching to the end of the load chain. Before use, please read and comply with the
instructions in this Owner’s Manual.
Safety Precautions
CAUTION
This Owner's Manual describes specific information regarding the Cylinder Control
Electric Chain Hoist (125kg & 250kg). Before use, read and comply with both the
ER2 Series Electric Chain Hoist (125kg to 5t) Owner's Manual and this manual.
At the time of unpackage, make records of the Product (serial) No. and the specific
for upcoming inspection with reference to the ER2 Series Electric Chain Hoist
(125kg to 5t) Owner's Manual.

Assembly
When some parts may not be pre-installed depending on the specifications of your order, please
properly attach them in accordance with the following instructions.
Attachment of Top Hook (or Suspender)
1) Remove the Shaft Retainer Clip using plier.
2) Remove Socket Bolt from the Shaft Retainer, and remove the Shaft Retainer.
3) Remove two Connection Shafts.
4) Remove the Top Hook and replace it with the Connection Yoke.
5) Insert two Connection Shafts into the hole of the Body size.
6) Mount the Shaft Retainer with Socket Bolt.
Attachment of Stopper & Cushion Rubber
Insert the load chain into the cushion rubber at both chain ends and then fix the stopper at the
following chain link with the socket bolts.
On the load side, 32nd link from the end of the load
chain
On the no-load side, 3rd link from the end of the
load chain
Attachment of Cylinder Switch to Load Chain
Attach the load chain to the cylinder switch on the
top of the cord holder with the chain pin, slotted
nut, and split pin.

Operations
Lifting and Lowering Load
While holding the stationary grip of the cylinder switch,
move the movable grip of the switch up and down by
using the thumb and index finger.
To lift, move up the movable grip.
To lower: move down the movable grip
Shifting Speed (Dual-speed Inverter)
The selector switch can shift the speed between
high and low in the dual speed inverter hoist.
Low-speed
Pressing the selector switch to the right sets the
low-speed to turn on the green lamp (LED).
High-speed
Pressing the selector switch to the left sets the
high-speed to turn on the red lamp (LED).
Emergency Stop
In case of equipment failure and other unexpected danger, the emergency stop can stop lifting
or lowering operation.
To make emergency stop, press the red button on the side of the cord holder.
To release emergency stop, turn the pressed button to the right (in the arrowed direction as
shown above)
Resetting Inverter (for Dual-speed Inverter hoist)
In dual-speed inverter hoist, overload or overcurrent may trip the inverter. In the case of the
inverter being tripped, press the emergency stop button to reset the inverter because the
emergency stop also brings the inverter to a reset
DANGER
Make sure that the split pin is securely bent.
Make sure that the stopper and cushion rubber are attached to the correct chain link.
Failure to follow these precautions may cause serious accidents leading to serious or
even fatal injury.

Attaching & Detaching Bottom Hook
To attach
Insert the bottom hook into the underside of the hook
attachment.
To detach
Turn the section A to the left as shown in the picture on
the right.
Adjustable Speeds of Dual-speed Inverter
In the dual-speed inverter, the low and high speeds can be adjustable by changing the inverter
parameters. Make sure that these parameters are properly set in accordance with the KITO ER2
Series Electric Chain Hoist (125kg to 5t) Owner's Manual as well as the KITO ER2 Series Electric
Chain Hoist (125kg to 5t) Inverter Manual.
DANGER
Do not make excessive operations (inching, plucking), which may cause failure.
Do not stop moving a suspended load by pressing the emergency stop button while
the hoist is in the normal operation.
Do not handle the hook attachment while a load is suspended. (Do not detach the
bottom hook.)
After the bottom hook is attached, make sure that the hook does not come off from the
hook attachment.
Failure to follow these precautions may cause serious accidents leading to serious or
even fatal injury.
