DANGER! 

Use the adjuster for lifting only,

lifting load. 

Use a qualified person to lubricate and maintain the adjuster.

attempt to lift a load if the load chains are kinked or 

 knotted.

DO NOT 

shock the load adjuster by allowing the attached load to    

 

fall freely, even for very short distances.

use the adjuster to drag the load across the floor. Always

 

position the load directly below the adjuster.

DO NOT 

allow anyone to stand, or pass, beneath the raised load.

was intended. 

Store adjuster in a dry, childproof area when not in use.

IMPORTANT: Before using the load sling adjuster ensure that you 

have read and understood the safety instructions in Section 1.

4.1 

Ensure that the load sling adjuster is suspended from a lifting    

 

system in which all components are capable of supporting the   

 

load to be lifted plus the load sling adjuster.

4.2 

Confirm that the load does not exceed the safe working load of  

 

the adjuster. 

4.3 

Position the carriage (A) at the centre of the beam (B) and  

 

 

suspend the adjuster, via the carriage, from the hook or  

 

 

shackle of the lifting device.

4.4 

Ensure that the slings

/

chains/ropes around the load are  

 

 

adequate and in good condition and that the load is directly    

 

below the adjuster.

4.5 

Attach slings/chains/ropes to adjuster load brackets (C). 

4.6 

Start to raise load and check whether the adjuster beam  

 

 

remains level. If it does not, 

lower the load

 and adjust the 

 

carriage towards the end of the beam which was low. Repeat    

 

this check and adjustment until the beam lifts horizontally.

NOTE:  DO NOT attempt to reposition the carriage when the 

 

adjuster is under load. 

Refer to fig.1

NOTE:  Only fully qualified personnel should attempt maintenance or  

 repair.

5.1 

Keep the load sling adjuster clean and regularly lubricate the  

 

threaded rod (D).

5.2 

Carry out a visual inspection every time the adjuster is used.

WARNING! The load chains and brackets are made from  

 

special alloy steels and precisely heat treated. DO NOT  

 

weld or re-heat treat. 

5.3 

Depending on the frequency of use and local conditions the  

 

adjuster will eventually show signs of wear at which point it  

 

should be replaced. Overloading or incorrect hooking  may  

 

distort the brackets, if this occurs replace immediately.
