Criteria for use
1 .Make sure that the class of the chain hoist is fit for condition of it's use. 2.The chain hoist should not be used to lift a load exceeding the rated load except for testing purpose. 3.Do not use a bottom hook which is not equipped with a safety latch or of which latch has no safety effect. 4.Do not use chain block on which chain stoppers are missing. 5.Do not wind the load chain directly around a load. 6.Do not quickly pull the hand chain on lifting and lowering operation. 7.Do not perform over-lifting and over-lowering. 8.Avoid an operation of so-called earth lifting. 9.Before operation check the load chain for twisting or tangling. 10.Can be used only after such twisting and tangling are corrected. 11.When the chain hoist is used in special conditions such as lower or higher temperatures, or corrosive atmosphere, etc.,consult us before use. 12.The chain hoist should not be modified by the users. 13.Do not leave the chain hoist for many hours with a load suspended. 14.Make a routine inspection before use. 15.Immediately stop operation the chain hoist when an abnormally big pulling for the hand chain is required. 16.Apply a lubricant to the load chain before use. 17.Use the chain hoist, applying lubricants to its gears, bearings, which are liable to wear. 18.Consult us whenever special usage of the chain hoist is required.

The methods for maintenance and inspection
Do not use parts and the chain hoist over the limit of use. If any wearing parts are found in excess of the standard limit of use as stated below in carrying out the daily and periodic voluntary inspections, they should be replaced for sure. Daily and periodic voluntary inspections, they should be replaced for use. When replacing load chains, be sure to use the load chain manufactured by us. Load chains manufactured by any others are not applicable.
Checking the load chain and its lifetime
The load chain begins to be broken from even one pieces of weak chain links and thus it is important to carefully inspect the whole chain. For checking the elongation, measure the inner length of 5 links with a vernier caliper as the above sketch shows. It is normally sufficient to check the links in a distance of approx. Every 50cm but check them by making the measuring distance shorter when the elongation of the chain is close to the limitation for use started in Table 2 so that none of them will exceed the limitation for use. Exchange the load chain with a new one which is found by visual check to be clearly deformed. Furthermore, do not weld a load chain to the original one by users themselves. Limitation of the deformed load chain for use(Table 2)

INSPECTION
In order to maintain quality operation of the product, a regular inspection schedule should be set up by each operator. All inspections should be reported and maintained in a dated record log. These records should be available to all personnel involved with the product, and should be available when a warranty issue is in question.
Definitions
The following definitions are from the EN13157 and will be used in the inspections procedure that follows.
Inspection Classifications
"Initial inspection should be done on all new, modified, and repaired products in accordance with Table 1. Thereafter, items to be inspected are indicated in Table 1 by F (Frequent) or P (Periodic). For hoists exposed to more severe environmental conditionsinspections should be more frequent. "
Frequent Inspections
"The operator or other designated person performs frequent inspections by doing a visual examination and by listening for unusual sounds while product is operating. Frequent inspections are usually performed on the following schedule: Normal Service- Monthly inspections Heavy ServiceWeekly to monthly inspections Severe Service- Daily or before each use to weekly inspections "
Periodic Inspections
"Designated person performs periodic inspections, which are more detailed inspections, by doing visual examinations of external and internal conditions. These inspections are done on the following schedule: Normal Service- Yearly inspection Heavy Service- Semi-annually inspections Severe Service- Quarterly inspections "

MAINTENANCE
Lubrication
Proper lubrication with machine oil is necessary to increase the life of the chain. Lubrication should be done based on usage and on a regular basis. It may be necessary on a weekly basis for heavy use or monthly if used less often.
· Clean the chain with an acid free cleaning solution to remove debris. · Apply oil to chain focusing on bearing surfaces such as interlink areas. · Do not apply oil to braking surfaces. · Gears and shafts run on roller bearings and do require lubrication.
BRAKE & TOP HOOK INSPECTION & REPLACEMENT
Disassembly
· Remove the cover using a standard socket wrench. · Remove the hand chain from the wheel. · Use needle nose-pliers to straighten the cotter pin. · Remove nut. · Remove secondary cover (protects the brake). · Remove brake · To disassemble the top hook remove the pin and the hook comes off.
Assembly
· Chain should be well seated in the wheel. · Put the hand wheel back on. · Should hear a click, indicating the brake is set. · Hand tighten the nut. · Push the cotter pin back in. · Use pliers to flare the ears so it stays in place. · Reattach the hand chain; making sure the weld is out. · Attach cover and tighten locknuts.
Storage of Hoist
· Store the hoist in a clean dry area. · Maintain proper lubrication of the hoist while it is being stored. · If the hoist is malfunctioning clearly mark it before placing it in storage.
Outdoor Hoist Usage
· Store hoist indoors when not in use. · Frequently inspect the hoist for signs of corrosion due to environmental factors.
