Keep your equipment clean, preferably cleaning after each use. From heads to cables and hoses to the remote control unit, keeping your grinder clean will give you optimal usage for the entire life of the machine
Check for uneven wear on tooling, cracks, or other damage. This may be an indication of a damaged tool holder.
Use OEM parts only.
Pay attention to strange sounds, scratch patterns, power loss, or anything else out of the ordinary.
Perform a deep clean on your mill weekly, breaking down the tips, checking for wear and erratic oscillation, belt slippage, and proper battery maintenance if applicable.
Every 100 hours do a full breakdown and inspection, being sure to clean the mill and make sure everything is in proper working order.
A yearly tune-up from a professional service provider will give you the edge when it comes to keeping your machinery up and running well.
