normal atmospheric conditions of the work place.
WARNING!
DANGER!
CAUTION!
Indicates an imminently hazardous situation which, if not avoided,
may result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
may result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,

2. SAFETY RULES
2.1 General
Failure to read and comply with the contents of this manual can result in serious bodily injury or
death and/or property damage. Although you may be familiar with this or similar equipment, it is strongly
recommended that you read this manual before installing, operating or maintaining the product.
Equipment described herein should not be used in conjunction with other equipment unless the
necessary and the required safety devices applicable to the system are used. The company shall have no
liability to the client for any loss, damage or other claims for compensation arising from this type of misuse.
Modifications to upgrade, re-rate, or otherwise alter this equipment should be authorized only by the original
equipment manufacturer.
DANGER!
1. NEVER use a hoist
for lifting, supporting or
transporting people.
2. NEVER use your foot to
apply pressure on the hoist.
3. NEVER use two or more hoists
together to lift load beyond the
rated capacity of hoist.
4. NEVER lift up load
beyond the rated
capacity of the hoist.
5. NEVER lift or
transport loads over or
near people.
2.2 Rules before use
Hoist operators are required to read this manual, the warnings contained
within it and follow safety instructions and warning labels on the hoist or lifting
systems. The operator is also required to familiarize themselves with the
hoist controls before being authorized to operate the hoist or lifting system.
CAUTION!
-1-

Do not use the hoist if there are deep nicks or gouges to the hook or load chain
or if the hook is stretched. Contact the distributor of the hoist and replace the
hook with new parts.
WARNING!
CAUTION!
1. Ensure that all information displayed on the name plate is clear and visible.
2. Check the hoist daily before use according to the Daily Inspection guidelines.
3. Check the weight of the load and choose a hoist of suitably rated capacity.
4. Ensure that hooks are not deformed and they rotate freely and smoothly.
5. Ensure that the function of the brake system is normal.
6. Lubricate load chain according to the recommendations of the manufacturer.
2.3 Rules for operation
WARNING!
2. NEVER use the hoist
chain as a sling.
1. NEVER use a twisted,
kinked, damaged or
stretched load chain.
3. NEVER use the hoist
as a support.
4. NEVER support a load on
the tip of the hook.
5. NEVER run the load chain
over sharp edges.
6. NEVER weld or cut a load
suspended by a hoist.
WARNING!
1. NEVER use a damaged hoist or one that is not working properly.
2. NEVER swing a suspended load.
3. NEVER use the hoist chain as a welding electrode.
4. NEVER operate a hoist so far that the bottom hook touches the hoist body.
5. NEVER operate a hoist so far that the load chain pulls the anchorage.
6. NEVER operate a hoist if excessive noise occurs.
7. NEVER allow your attention to be diverted when operating the hoist.
2.4 Rules after use
Put down the load slowly and safely after lifting.
NEVER suspend a load for an extended period of time.
CAUTION!
WARNING!

-3-
2.5 Inspection and maintenance
Ensure that only qualified service personnel inspect the hoist periodically.
Do not attempt repair of a hook by heat treating, bending or attaching anything
by welding. Such procedures will weaken the hook and may cause failure.
CAUTION!
WARNING!
2.6 OTHER
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.
CAUTION!
WARNING!

4. OPERATION
4.1 Introduction
This hoist has been designed for the vertical lifting and lowering of loads, by hand, under normal atmospheric
conditions of the work place. However, since dealing with heavy loads may involve unexpected danger, all of
the Safety Rules must be followed.
Working Environment Safety: the operator must be aware of the following points whilst using the hoist.
1. The operator must have a clear and unobstructed view of the entire travel area before operating the
hoist. When this is not possible, additional personnel must serve as scouts in the nearby area to assist.
2. The operator must check the entire travel area is safe and secure before operating the hoist.
5. INSPECTION
5.1 General
There are two types of inspection, the Daily Inspection performed by the operator before using the hoist,
and the more thorough Periodic Inspection performed by qualified service personnel who have the authority
to remove the hoist from service.
5.2 Daily inspection
Item Method Discard criteria Remedy
Name plate Check visually All information should be clear and visible. Replace the name
plate
4.2 Method of operation
1. Place the selector switch on the handle in the central position (N).
2. Adjust the load chain to a suitable length for connection to the load.
NEVER pull the load chain sharply whilst the selector switch is set in the central position
(N) as this may result in the brake engaging after which a reset will be required.

6. MAINTENANCE
6.1 General
Incorrect maintenance may result in serious bodily injury or death. Only trained and competent personnel
should maintain this equipment.
Always test the hoist using the information provided in this manual before
returning it to service following any maintenance work.
CAUTION!
WARNING!
1. Always take care to ensure that hands or clothes do not get caught in the chain, idle sheave or other
moving parts.
2. Never operate the hoist when it requires maintenance.
3. Always inspect all parts if abnormal difficulty in lifting and lowering occurs.
4. Never perform maintenance on the hoist whilst it is supporting a load.
5. Always wipe off dirt and water.
6. Always store the hoist in a dry and clean place.
6.2 Lubrication
Ensure that the load chain, hook latches, top/bottom hook pin and hook yoke, etc. are kept lubricated.
The load chain is one of the important parts of the hoist and should be lubricated well with machine oil.
CAUTION!
1. (1) Lubricate the load chain weekly, or more frequently, depending on severity of service.
2. (2) Lubricate the load chain more frequently than normal if used in a corrosive environment.

-10-
Problem Cause and explanation Remedy
The hoist will not lift
the load (no clicking
sound).
Pawl not engaging with ratchet disc; possible
contamination with dirt or foreign material.
Clean and lubricate the
pawls and ratchet disc
assembly.
Pawl spring is damaged. Replace pawl spring.
Ratchet spring is loose or damaged. Tighten or replace
ratchet spring.
Load slips or drifts
while being lowered.
Dirt or corrosion or foreign material in hoist
components.
Inspect and correct
problem. Keep hoist
clean and lubricated.
The brake is slipping. Friction discs are worn
from long term use, or are damaged from
overloading or misuse.
Replace friction disc. See
chapter 5. INSPECTION
for minimum allowable
thickness. Do not
overload the hoist.
The load drops the
instant lowering is
started.
The braking surface is dirty. During assembly, the
braking surface must be wiped clean of dirt.
Clean or replace the
brake assembly.
The braking surface is oily. The braking surface
must not be allowed to become soiled with
grease or machine oil because it is a dry type
brake.
Clean or replace the
brake assembly.
The hoist will not
lower the load.
The brake has caught. (Hoist was left under
loaded condition for an extended period, or was
shock loaded while in operation.)
Place selector lever in
DOWN position and pull
hard on the lever handle
to re-set the brake.
Resume operation.
Brake components are corroded or damaged.
Replace damaged
components; keep hoist
clean and lubricated.
The chain is tight
when lifting, even
without a load.
(A squeaking noise
can be heard at
times.)
Gear teeth are worn from long term use, or for
not being greased regularly.
Disassemble and replace
the load gear, gear case
and side plate.
7. Troubleshooting
Any maintenance or repair of the lever hoist should be performed by properly
trained personnel.
