COVID-19 situations are getting worse day by day. Buying behaviors and economic priorities for purchasing new goods have changed. In these days, maintenance of existing equipment has gained more importance. For the purpose of training the maintenance workers or end users in this pandemic situation, augmented reality is like a blessing today. The maintenance procedures can be communicated remotely on demand with the help of web based AR and android apps. This paper describes advantages of using AR based instruction over paper based instruction to train maintenance operators. The authors have developed web based AR and android apps for augmenting 3D models. Many benefits observed by using this technology are reduced human errors reduced execution time, reduced downtime of equipment, reduced cost, and increased productivity. Paper mainly focuses on ways of delivering maintenance instructions remotely.
