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

Replace the name plate

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.

Troubleshooting

friction discs.When used at high frequency without performing maintenance regularly, the friction discs will wear down. This will create gaps between the friction disc and hand wheel and cause the brake to slip.| ****

Disassemble and replace the friction discs.

The pawl produces absolutely no sound and fails to lift the load.| The pawl has been improperly assembled. If the pawl is assembled facing the wrong way, or

otherwise assembled incorrectly, it will not cleanly mesh with the ratchet disc.

| Disassemble and then reassemble parts correctly.
The pawl is not moving smoothly. Unless maintenance is performed regularly, dirt will adhere to the grease on the pawl and pawl shaft. Movement will become sluggish and the pawl will remain stuck in the kicked out position.| Disassemble and then reassemble parts correctly.
The chain is tight when lifting, even without a load. ( A squeaking noise can be heard at times.)| Worn gear teeth or worn bearing. Unless maintenance is performed regularly, greased parts will dry, resulting in wear and damaged, improper meshing gears.| Disassemble and replace the pinion, load gear, gear case, side plate and ball bearing.
Improper lowering or the chain is extremely tight when lowering.| The brake is too tight. Due to shock during work, or because the load was left suspended for a  long period of time, the brake tightened.| Free the brakes forcibly by jerking the hand chain.
The brake is rusted. Unless maintenance is performed regularly, rusting will occur.| Disassemble and replace parts where necessary.
The load falls the instant lowering is started.| The braking surface is dirty. During assembly, the braking surface must be wiped clean of dirt.| Disassemble and then reassemble parts correctly.
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.| Disassemble and then reassemble parts. Do not oil or grease the braking surface or friction plates.
Load slipping| The braking surface is dirty or oily. The braking surface must not be allowed to become soiled with grease or machine oil because it is a dry- type brake. During assembly, the braking surface must be wiped cleaned of dirt.| Disassemble and then reassemble parts. Do not oil or grease the braking surface or friction plates.
The brake does not function when lifting a light load of less than 10% of rated hoist capacity.| The brake mechanism may have disengaged following full extension of the load chain causing the chain end stop to come in to contact with the hoist chassis.| Lift a load of at least 10% of the rated capacity of the hoist to re-engage the brake.
