Whenstartingupa balancer, w esuggestthatthe followingprocedure is used:
Connectthe balancerto the main structurethrough the suspensionhook, if present, or fixing hole.
Connect t hesafetydeviceto the secondary structure.
- Lift the load to be hangedto the balancer.
- Hangthe loadto the balancer t hroughthe properhook/snap hook,
- Lowerthe loadby unwinding thebalancer's ropeandadjustthestrokelimiterclampto avoidbringing theloadabovetheoperator.
- Adjustthe balancerstrengthas longasthe hangedloadis balanced. R otateinthedirectionofthe + signto increase thestrength
of the balancer. R otateinthe direction of the signto decrease thestrengthof thebalancer.
In caseof installation of the balancer a t a considerable height,usethe dedicated extensionropesto bringthe loadat the needed
workingheight(theloadmustnotbeabovethe operator).
Ensurethatthe workingareaisadequately lightened to allowa goodoven.'iew of theoperations and of all theequipment, a voiding

Always connect the safety suspension

not be more than 100 mm. Tighten the nuts of the clamps 21215 (Fig.l) with a torque of 2 Nm.
BALANCER ADJUSTMENT
Toallowthebalancer t o balance heavier l oadswithintheloadcapacity a ccepted, turnknob(4)asshown in (Fig.2) ( anticlockwise,
indicated bythe "+".symbol, a djustment i s not continuous butin steps),aftereachstep,the knob(4) mustgobackintocontactwith
plate(5) (Fig.2).Forlighterloads,extractthe knob(4) and,grippingit tightly,tum it clockwise as shownin (Fig.3)aftereachstep,

Afteradjusting the load,checkthatthe ropecanmovefreelyalongall its length:the movement mustnotbelimitedbythe complete

If necessary, moveandblockthe clamp(12)(Fig.2)to limitthe upwardrun.
Do not unhook the load if the clamp (12) (Fig.2) does not lean onto the rope's swaging (POSITION

Do not leavethe load if it is not in a verticalposition;
- Donot swing/throw the hanging loadto anotheroperator;
