1. DEFINITIONS

:indicates a potentially hazardous situation which, if not avoided, could result

in death or serious injury.

: indicates a potentially hazardous situation which, if not avoided, may result in

minor or moderate injury. It may also be used to alert against unsafe

practices.

WLL: indicate maximum mass (working load limit) which a hoist is designed to support in

general service.

2. INTENDED PURPOSE

This hoist has been designed for vertically lifting and lowering loads, by hand, under normal atmospheric

conditions of the work place.

3. MOUNTING

NEVER Avoid the following when mounting the chain hoist.

Failure to comply with these instructions may result in death or severe injury.

- Ensure that only trained or competent persons install the chain hoist.

- Do not install the chain hoist within the range of movement of other devices (equipment), such as a

trolley.

ALWAYS Comply with the following instructions when installing the chain hoist.

Failure to comply with these instructions may result in death or severe injury.

- Check that the structure for mounting the chain hoist has sufficient strength.

- Fix the Top Hook to the structure securely.

- Before using the chain hoist with a trolley, read the Instruction Manual of the trolley carefully and

install it by adjusting the rail width.

- Install a stopper at both ends of the traversing rail for the trolley.

4. BEFORE USE

4.1 Safety summary

Danger exists when heavy loads are transported, particularly when the equipment

is not being used properly or is poorly maintained. Because accidents and serious

injury could result, special safety precautions apply to the operation, maintenance

and inspection of the KITO manual chain hoist CF series.

NEVER use a hoist for lifting, supporting or transporting people.

NEVER lift or transport loads over or near people.

NEVER lift more than WLL which is shown on the name plate.

WARNING

OVER LORD

WARNING

CAUTION

—2—

ALWAYS let people around you know when a lift is about to begin.

ALWAYS read the operation and safety instructions.

Remember proper rigging and lifting techniques are the responsibility of the operator.

Check all applicable safety codes, regulations and other applicable laws for further

information about the safe use of your hoist.

More detailed safety information is contained in the following pages. For

additional information, please contact KITO Corporation or your authorized KITO

dealer.

4.2 Safety instructions

4.2.1 Before use

ALWAYS allow the instructed (trained in safety and operation) people to operate the hoist.

ALWAYS check the hoist before daily use according to the “Daily inspection” (Refer to

7.2).

ALWAYS make sure that the chain length is long enough for the intended job.

ALWAYS check that the hook latches work properly and replace missing or broken hook

latches (Refer to 7.3).

ALWAYS check the brake (Refer to 7.3).

ALWAYS oil the load chain regularly (Refer to 8.1.2).

ALWAYS use two hoists which each has WLL equal to or more than the load to be lifted

whenever you must use two hoists to lift a load. This will provide adequate

protection in the event that a sudden load shift or failure of one hoist occurs.

NEVER use a hoist without a hoist name plate.

NEVER use modified or deformed hooks.

NEVER use non-authentic chains on the hoist.

4.2.2 While operation

ALWAYS make sure that the load is properly seated in the hook.

ALWAYS tighten the slack out of the chain and sling when starting a lift to prevent a

sudden loading.

NEVER operate a hoist unless the load is centered under the hoist.

NEVER use the hoist chain as a sling.

WARNING

ALWAYS

read safety

instructions

—3—

NEVER use a twisted, kinked, damaged or stretched load chain.

NEVER swing a suspended load.

NEVER support a load on the tip of the hook.

NEVER contact the load chain over an edge.

NEVER weld or cut a load suspended by a hoist.

NEVER use the hoist chain as a welding electrode.

NEVER operate a hoist so far that the bottom hook touches the hoist body.

NEVER operate a hoist so far that the load chain pulls the anchorage.

NEVER operate a hoist if excessive noise occurs.

NEVER use the capsized load chain.

4.2.3 After operation

ALWAYS set the load down safely after carrying.

NEVER suspend a load for an extended period of time.

NEVER leave a suspended load unattended.

NEVER throw a hoist.

4.2.4 Maintenance

ALWAYS let the qualified service personnel inspect the hoist periodically (Refer to 7.3).

NEVER splice, add and weld a load chain for extension.

4.2.5 Others

ALWAYS consult the manufacturer or your dealer if you plan to use a hoist in an

excessively corrosive environment (salt water, sea air and/or acid, explosive

environment or other corrosive compounds, etc.).

NEVER use a hoist which has been taken out of service until the hoist has been

properly repaired or replaced.

NEVER remove or obscure the warning tags and labels.

Warning tags are installed on a hand chain.

6. OPERATION

6.1 Intended purpose of hoist operation

This hoist has been designed for vertically lifting and lowering loads, by hand, under normal atmospheric

conditions of the work place.

However, since dealing with heavy loads may involve unexpected danger, all the “Safety instructions”(Refer to

3.2) must be followed.

6.2 Safety working environment

The operator must be aware of the following points while using the hoist.

(1) The operator must have a clear and unobstructed view of the entire travel area before operating the hoist.

When not possible, a second or more persons must serve as scouts in the nearby area.

(2) The operator must check the entire travel area is safe and secure before operating the hoist.

6.3 Operation

ALWAYS take care hand or clothes not to be caught in a chain, idle

sheave or other moving parts.

(1) Face the hand chain wheel side of the hoist.

(2) To raise the load, pull hand chain clockwise.

(3) To lower the load, pull hand chain counterclockwise.

(4) There are risks of overheating of the breaking system during

prolonged lowering of loads. If you are considering of the use under

such condition, consult KITO.

Remark: The clicking sound of the pawl when a load is being raised

indicates normal operation.

6.4 Hoist storage

Observe the following points when storing the hoist.

ALWAYS store the hoist in no load condition.

ALWAYS wipe off all dirt and water.

ALWAYS oil the chain, top pin, chain pin and hook latches.

ALWAYS hang in a dry place.

ALWAYS check the hoist for abnormalities when using the hoist after a period of non-use according to the

periodic inspection procedures (Refer to 6.3).
