Question about Mercury Floor Machine Mercury: Ultra DC Burnisher 21in - 1.5hp - 1500rpm - Floor Machine

1 Answer

Our Ultra D.C. Burnisher starts instantly when the cord is plugged in, even before pulling the safety trigger levers. Can you suggest a reason for this?

I have opened up the Safety Trigger Lever assembly housing, but see nothing broken or miss-aligned.

The switch has gone bad. Very common on these. The contacts in the switch wear out and then get welded together. The motor draws a lot of power when first started and this is ******* the switch.
