SAFETY PRECAUTIONS
Misuse of an electric chain hoist can cause dangerous situations such as dropping of the hoisted load
or electrical shocks. To ensure proper use, it is essential that this instructions booklet and the manual of
any other equipment that is to be used at the same time be read and fully understood before installing
or servicing the equipment.
Before use, the operator must be fully familiar with; the equipment, with all of the safety procedures
and the warning provisions. In this instructions booklet two categories “DANGER”and“CAUTION” .
EXPLANATION OF THE WARNINGS
DANGER DANGER are incorrect usages that can lead to death or serious injuries.
CAUTION CAUTION are incorrect usages that can lead to light injuries or property damage.
Situations classied as "CAUTION “ may result in serious conditions in some cases.
Precautions must be obeyed no matter what category they come under.
!
!
• Serious injuries are permanent disabilities, wounds that require hospitalization or prolong
outpatient treatment such as; loss of eyesight, injuries, burns, electrial shocks, and broken bones.
• Light injuries mean burns and electrical shocks that do not require hospitalization and prolong
outpatient treatment.
• Property damages are major losses to the building, equiment or machinery.

1. OVERALL HANDLING
2. IMPORTANT!!
The following warnings and safety procedures are essential for avoiding possible bodily injury and
property damage.
2.1 BASIC SAFETY PROCEDURES
CAUTION
NEVER lift more than the rated load marked on the hoist.
NEVER use the hoist to lift, support or transport people.
NEVER lift or transport loads over or near people.
ALWAYS read the operation and safety instructions.
2.2 SAFETY PROCEDURES PRIOR TO USE:
CAUTION
ALWAYS The operator of the hoist must be a person who is completely familiar
with all safety and operation procedures.
ALWAYS Check the hoist before use and conrm that the load chain is well
lubricated.
ALWAYS Check the brake before use.
ALWAYS Check the safety latches to see if they work properly. Broken and missing
safety latches must be replaced immediately.
ALWAYS Use genuine NITCHI parts and chains.
NEVER Modify the hoist.
NEVER Use modied or deformed hooks.
NEVER Use a hoist when malfunction, unusual performance, damage or
extensive wear are found.
NEVER Abuse the over-hoisting/over-lowering limit switch mechanism by using it
regularly.
NEVER Remove or obscure the warnings and nameplate on the hoist.
DANGER
The unit (electric chain hoist and trolley) must be operated only by people who fully understand the operating instruc-
tions booklets and the precautions on the warning name plates. People without the necessary qualications must not
operate the unit or carry out hook and sling connecting operations. lnspect the unit before operating it, and carry out
periodical inspections. Never hoist/lift people!

SAFETY PROCEDURES DURING OPERATION
CAUTION
ALWAYS Set the load properly in the hook.
ALWAYS Conrm that the safety latch has closed completely.
ALWAYS Take up the slack of the load chain and sling carefully, and make the initial
load lifto shock as small as possible.
ALWAYS Use a hoist within the“ Duty rating“ , ED % or time rating.
ALWAYS Avoid excessive inching and make sure that the hoist motor completely
stops before reversing the operating direction.
NEVER Allow your attention to be diverted when operating the hoist and never leave a suspended
load unattended.
NEVER Operate the hoist unless the load is centered underneath it.
NEVER Use the hoist with twisted, kinked, damaged or worn chain and never
attempt to lengthen the load chain.
NEVER Use the load chain as a sling and never apply the load to the tip of the hook.
NEVER Use the load chain so that it comes in to contact with an edge.
NEVER Allow the chain or hook to be used as a ground for welding and never touch them with
live welding electrodes.
NEVER Abuse the friction clutch by using it frequently. lmproper use can severely
damage the hoist and lead to serious injuries.
NEVER Pull on the pendant control cable.
MAINTENANCE SAFETY PROCEDURES
CAUTION
ALWAYS Have a qualied service person inspect the hoist periodically.
ALWAYS Clean the hoist thoroughly and keep the load chain well lubricated.
ALWAYS Only allow the friction clutch to be adjusted at an authorized NITCHI Service Shop .
NEVER Attempt to extend, repair or weld the load chain.
NEVER Touch live electrical parts.

INSTALLATION
CONNECTING THE CHAIN BUCKET
PROHIBITED
MANDATORY
!
• Do not modify the chain bucket assembly.
• Always attach the chain bucket assembly before
raising the hoist into position.
DANGER
1. Connect the chain bucket assembly with
the chain bucket pins.
2. Feed the load chain into the chain bucket
gradually and neatly from the end.
3. The load chain may tangle and the hoist
may not operate correctly when the load
chain is placed into the chain bucket as-
sembly in one bundle.
4. The inside of the chain bucket assembly
must be cleaned periodically when the
hoist is used in an area where dust and
foreign matter can enter the chain bucket
assembly.
Open the split pin as shown in the drawing. Code Dimension A

LUBRICATION
CIRCUIT BREAKERS
1. Lubricate the load chain before use with machine oil or gear oil.
2. When the gear section of the hoist is disassembled, always change the grease within the gear case.
Use heavy duty (disulde molybdenum) grease.
3. When the gear box section of the Motorized trolley is disassembled add an extra coat of heavy duty
grease (disulde molybdenum grease) to the gears. The gear box section normally does not need
to be regularly lubricated.
Paint the gear teeth section of the Gear wheel
and Pinion with cup grease.
1. Always install a circuit breaker.
The circuit breaker must be exclusively for the hoist and independent from other machinery.
2. Select an adequate capacity circuit breaker from Table 3.

POWER SOURCE CABLE
ADJUSTING THE TROLLEY WIDTH
1. With electric chain hoists that use the electrical cable power feeding method, always be sure to use
the appropriate sized cabtyre cable (tough-rubber sheathed cabIe).
2. Use a larger size cabtyre cable when the cable length is long, and when there is a possibility
that the hoist and the motorized trolley will be operated together at the same time.
3. Please refer to Table 12 for the specications of long cabtyre cables.
Adjust the width between the trolley wheels as follows:
1. Remove the Hexagonal nuts, and remove the side-plate.
2. Adjust the width by increasing or decreasing the number of inner spacer washers. Refer to Tables 4
and 5 for the appropriate combination of inner and outer spacer washers.
3. Tighten the Hexagonal nuts for the Stay bolts.
4. Conrm that the Top holder is positioned directly under the center of the trolley beam.
