Lease Out Of Premises And Plant

HI, I am a proprietor and i have leased out a bottled water manufacturing plant in July 2019 in Maharashtra, India. I was shown the plant in evening hours when it was just put off, and i was shown output, basis which i leased it out. On receiving possession i realized that machinery is not upto mark and i have spent good amount on repairs. Still the production is not as much to make any profits, I am currently running in losses, coz machine breaks down almost every week and there is down time owing to repair. The agreement is for 3 years. There is no early termination clause. I have paid refundable deposit too. The lessor threatens to pay 3 years lease in case i wish to opt out. Please help with way out.
