Stars picked up three valuable points when they thumped AmaZulu 4-1 at Goble Park on Saturday to boost their chances of survival.
Ea Lla Koto have since moved to position 13 on the log, seven points above bottom-placed Maritzburg United with only six games left before the end of the season.
Kavazovic has since declared that he is ready to give everything to make sure Free State Stars remain in the Absa Premiership next season.
"I am happy because I am a loyal soldier of Free State Stars," said Kavazovic after the morale-boosting result against Usuthu.
"I have committed my personal professional career and all my life to Free State Stars and every step that I can take to help the team avoid relegation."
The Serbian coach revealed it was the first time seeing everyone in the club happy since he arrived in the country after his team beat AmaZulu.
"This is the first time this season everyone in this team except me is in good health," he added.
