OPERATING PROCEDURE

Adjustment of Sprial Spring ( Refer to illustration of Fig.2 )
3).	Adjust the tension of spiral spring to suit for loading weight and working condition by turning of worm. Tension of spiral spring increases when turing the worm clockwise direction. To decrease the tension of spiral spring for load in lesser weight turn worm counterclockwise direction. You can judge the approximate loading weight through the plastic gauge. When supplying the products from factory, the tension of spiral spring is set at a medium position.
	NOTE :-  AVIOD ADJUSTING THE SPIRAL SPRING OVER OR BELOW THE RATED CAPACITY OF THE BALANCER. USE BALANCER ALWAYS WITHIN THE BALANCE RANGE. IF THE SPRING IS WOUND OVER ITS MAXIMUM CAPACITY, IT WILL SHORTEN THE STROKE OF THE CABLE AND DECREASE THE LIFE OF SPIRAL SPRING. AND IF THE SPRING IS LOOSENED TO LOWER TENSION THAN MINIMUM CAPACITY, SAFETY DEVICE WILL ACT AND STOP OPERATION PREMATURELY.
Replacement of attached equiprements ( Refer to illustration of Fig.3 )
4).	The following procedure shold be adopted, in the following order if it is necesary to replace any parts during operation of spring balancers,
	Pull all length of cable (wire rope) out of drum, and set stopper pin (8) at a groove as illustrated on fig. 3 and lock drum (19). After making sure of locking the drum, change attached parts. NOTE :-  IT IS VERY DANGEROUS TO ATTEMPT TO REPIACE ANY PARTS BEFORE MAKING SURE THE DRUM IS LOCKED BY THE STOPPER PIN TO PREVENT THE SPRING SNATCHING BACK. THEREFORE, DO NOT RELEASE MANUAL DRUM LOCK WITHOUT ATTACHING FULL LOAD. If weight of total load to be attached afresh is different from previous equipment, re-adjust the tension of spial spring anew.
