Product Introduction

FD mine exploders

good quality

cheap price

Use special tools to open the shell back cover then put into the battery before use. Attention the

battery polarity can’t opposite. Don’t touch the face of exploder-proof. Tighten the screws after put into battery. It can be used with an explosive mixture of methane and coal dust coal mine.
