Always run check on equipment when we come back from a job, service everything at appropriate intervals, and do a start-up run before we head to a job site.
I spent a number of years as an industrial maintenance and this has been a BIG aspect of my work since then. PROPER maintenance can reduce down-time to zero.
If accidents occur, we carry serious med kits & have a service vehicle on 24 hour call.
We are a small company, but my years of previous employment have had a great impact on how I run my own company.
