Safety Precautions
Chapter 2 Inspection
• Disassembly and assembly of the electric chain block must be performed by maintenance
engineer.
• Do not use the part exceeding the service limit or criteria and the parts other than genuine part
for KITO electric chain hoist.
Even if the part is genuine KITO part, it cannot be used for other model. Refer to Disassembly/Assembly Manual
(Annex) for the correct use of the part.
• Do not adjust or disassemble the Electromagnetic Brake, the Friction Clutch and the Friction
Clutch with Mechanical Brake.
• Do not adjust the set nut.
• When oiling the Friction Clutch and the Friction Clutch with Mechanical Brake, use KITO genuine
oil (manufacturer specified oil).
• Do not carry out the inspection of electric chain hoist with a lifted load.
• Do not use the electric chain hoist removing the cushion rubber, the chain spring and the
stopper.
• Turn off the main power when carrying out the inspection.
• When using oils such as gear oil and grease, avoid places with fire or sparks.
Failure to comply with these instructions may result in death or serious injury.
Prohibited
Mandatory
• Put the electric chain hoist on the floor or work bench when performing the repair and
disassembling of the electric chain hoist.
• Even if each component of the electric chain hoist does not exceed the service limit, replace the
part exceeding the total operating hours derived from the grade indicated on the electric chain
hoist and the load factor.
• Do not use the electric chain hoist when any abnormality was observed during the inspection.
Indicate “FAILURE” on the hoist and contact with maintenance engineer or KITO for repair.
• After completion of the inspection (frequent, periodic), perform the functional check and make
sure that the electric chain hoist operates correctly.
• When performing the functional check, be sure to perform the capacity test after no load test.
Failure to comply with these instructions may result in death or serious injury.
CAUTION
• Indicate “CHECKING” when performing the inspection.
When a crane is operated erroneously during the inspection, it may result in the accident such as fall-off of parts and
tools and downfall.
• Wear protection equipment such as protection goggles and gloves depending on the work
contents.
Otherwise it may result in the injury due to scattered oil or sharp edge of a part.
• Pay attention to work method, work procedure and work posture.
If the product or the part is heavy, your hand is caught or your waist is hurt.
Especially be careful for the work on an unstable scaffold such as the work at high lifted place using stepladder.
• Wear helmet and safety belt when carrying the high lift work.
Otherwise it may result in injury or downfall accident.
• Remove the oil attached to the product or spilt on the floor.
Otherwise it may result in injury due to drop of the product or overturning.
• Keep the work area clean when disassembling the product.
Assembling or mixing the part other than genuine part may result in the damage of the product or the accident due to
defective operation.
