7. Maintenance

PAROL6 needs little: belts that stay tight, set screws that stay put, switches that trigger. Check them at the intervals below and after any collision.

Interval	What
Before each session	The E-stop works (press it with the robot enabled); nothing in the workspace; the cables and tubes free
Monthly, or every 50 hours	Inspection: belts, couplers, switches, fan, printed parts
After a collision, a fall or a lost step	Inspection, then Checking the homing
When a belt slips or a joint is loose	Belts, Couplers and threadlocker

Before any work inside the base, unplug the supply and touch earthed metal: static electricity damages the control board and its drivers.
