Persons performing disassembly/reassembly
Disassembly/reassembly shall be performed by a competent person (a person duly authorized by the company as having
expertise on the structure and device of the electric chain hoist) or consult KITO.
This Disassembly and Reassembly Manual includes contents to prevent injury to any person performing
disassembly and reassembly, users, and other persons and damage to property, and to disassemble/
reassemble the electric chain hoist safely and correctly.
Before performing disassembly/reassembly, be sure to read and follow this manual as well as the EQ
Series Electric Chain Hoist Owner’s Manual (separate document) since its contents are also important for
disassembly/reassembly.
Disassembly/reassembly of the electric chain hoist is required operations for regular inspection and repair.
Carry out disassembly/reassembly properly in accordance with these manuals.

The disassembly and reassembly procedures are described based on the representative model.
Note that components may be slightly different for different capacities.
The specications may be changed without prior notice and may be different from the actual products.
• Only competent persons with expertise and experience must disassemble/reassemble the electric
chain hoist. Alternately, contact the nearest distributor or KITO. Disassembling/reassembling
improperly causes death or severe injury.
Perform disassembly and reassembly in correct procedures as described in the manual.•
Do not extend the load chain.•
Before reassembling the parts such as gear, clean and remove oil and dust on them.•
Especially when a plastic hammer is used, clean them thoroughly so that no chip of the
hammer remains inside.
Prepare anti-loosening (screw lock) for bolts. Apply it to the specied locations.•
Use only authorized parts for replacement.•
Failure to follow these instructions may result in death or severe injury.
• When reassembling, follow the instructions below.
Before reassembly, remove dust and oil on the part to be reused.•
Insert snap rings completely in the groove.•
Assemble the load chain without torsion.•
Failure to follow these instructions may cause bodily injury or loss of property arising from damaged product
or dropped parts.
• When reassembling, replace the following parts with new ones.

Install the load chain(1) B12 so that the
welded part comes outside of the load
sheave A11 .
Be sure to insert a horizontal link rst (as
•
shown in the gure) into the chain guide A24 .
Insert the load chain from the load side(2)
(bottom hook side) of chain guide, wind it
up by rotating the load sheave manually
to guide it out to the load chain outlet (no
load side).
Once engaged with the load sheave, shift the
•
body with stator to the no load side and rotate
the load sheave manually. The load chain is
taken up and comes out smoothly.
Re-check the orientation of the load chain,(3)
and check for any twist.
• Insert the load chain so that the welded part comes outside when it is engaged with
the load sheave.
Failure to follow this instruction may cause defective operation or abnormal wear and result
in severe injury due to a falling load.

DANGER
• Do not adjust the friction clutch.
Failure to follow this instruction may result in death or severe injury.
Insert the load gear(1) A16 to the load sheave
A11 , and lock it with a new snap ring A17 .
The load gear should be assembled with its
•
concave surface facing upward. (If assembled
the other way around, a groove for the snap
ring is invisible.)
Make sure that the snap ring is inserted fully.
•
Assemble the set pins S(2) A6 (2 pcs.).
Assemble the friction clutch(3) A9 .
Assemble the ball bearing(4) A30 to the
friction clutch.
Put new packing G(5) A37 on the body with
stator A4 , and strike the gear case A29
with a plastic hammer to assemble.
Care should be taken not to catch the lead
•
wires.
Use one machine screw socket bolt (shorter)
•
A35 and ve machine screw socket bolts
(longer) A36 , totally 6 of them.
Assemble the gear case temporarily to the
•
body with stator with the machine screw socket
bolts, and then, tighten them diagonally and
uniformly.
