Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
Ø
The purpose of the BRM-35A is to drill through steel using annular cutters or
standard twist drill bits (when using the optional drill chuck).
Ø
These drills are designed to magnetically adhere to a ferrous surface using their
electromagnetic base. Generally these drills are designed and used to drill through
mild steel. This magnetic base will not work without a power connection.
o
NOTE: The entire magnetic base must cover the work area to have full
magnetic adhesion. Using only a portion of the magnet is dangerous! Make
sure the base fits completely on the surface.
Ø
These machines can be used vertically, horizontally or overhead (inverted) provided
strong enough magnetic adhesion and an acceptable work environment. NOTE: For
safety, the safety chain should always be used incase of an accidental power failure
or other loss of magnetic adhesion.
OPERATIONAL PRINCIPLES
Ø
The main drilling shaft rotates in the forward direction. The main drilling motor
connects to the tool holder to make contact with a surface and slowly bore a hole.
Using the feed handles on the side of the drill, the user can raise or lower the drilling
motor.
MACHINE COMPONENTS
Ø
The main components of the BRM-35A are the tool holder, gearbox, motor, frame and
magnetic base. The tool holder is driven by the transfer case and the motor.
o
These components must be not be removed except by a qualified technician.
Power must be disconnected prior to any service.
