SAFETY RULES

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.

Rules before use

CAUTION!
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.

WARNING!
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.

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.

Rules for operation

WARNING!

1. NEVER use a twisted, kinked, damaged or stretched load chain.
   
2. NEVER use the hoist chain as a sling.
   
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.
8. NEVER lift a load weighing less than 10% of the rated capacity of the hoist.
9. NEVER fully extend the load chain so that the end stop touches the hoist chassis.

Rules after use

CAUTION!
Put down the load slowly and safely after lifting.

WARNING!
NEVER suspend a load for an extended period of time.

Inspection and maintenance

CAUTION!
Ensure that only qualified service personnel inspect the hoist periodically.

WARNING!
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.

OTHER

CAUTION!
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.).

WARNING!
NEVER use a hoist which has been taken out of service until the hoist has been properly repaired or replaced.

Technical specifications

OPERATION

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.

Operational use

Face the hand chain wheel side of the hoist, pull the hand chain clockwise to raise the load and counter clockwise to lower the load.
The clicking sound of the pawl when the load is being raised indicates normal operation.

Overload device (if fitted)

The optional overload protection device will come in to operation at between 1.3 to 1.8 times the WLL of the hoist.

INSPECTION

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.

Daily inspection

Periodic inspection

Periodic inspection shall be made at the interval shown below and should follow the given procedures. NORMAL (Normal use): Six monthly inspection
HEAVY (Frequent use): Quarterly inspection
SEVERE (Excessively frequent use): Monthly inspection

MAINTENANCE

General

Incorrect maintenance may result in serious bodily injury or death. Only trained and competent personnel should maintain this equipment.

WARNING!
Always test the hoist using the information provided in this manual before returning it to service following any maintenance work.

CAUTION!

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.

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. Lubricate the load chain weekly, or more frequently, depending on severity of service.
2. Lubricate the load chain more frequently than normal if used in a corrosive environment.
