Warning: when using electrical tools, the following basic safety
measures need to be observed to prevent electric shock, injury or fire.
Read all these instructions before using this electrical tool and keep
them in a safe place.
1 Safety instructions
The boiler pipe preparation machines (hereinafter referred to as BRB 2 or
BRB 4) are state-of the-art machines. Using these machines in a way other
than that described in this manual can lead to personal injuries to the user or
of third parties. It may also damage the machine or other equipment.
Therefore:
always ensure that the machine is in good working order.
Comply with these safety instructions.
Keep complete documentation close by the machine.
1.1 Intended use
Only use BRB 2 and BRB 4 to process (face and bevel) metallic pipe ends
up to 2 or 4 inches. The machine should only be used on empty,
deenergized pipes. Temperature range: -15°C to 40°C.
1.2 Improper use
The machine is not intended for use by private consumers. Do not use the
machine on energized piping, in explosive atmospheres or on
contaminated pipes.
Do not use the machine outdoors when it is foggy, raining, during a
thunderstorm or when the relative humidity > 80% (measured at 20°C).
Do not use the BRB as a drive for applications other than those listed under
proper use (chapter 1.1).
1.3 Machine constraints
Space requirement/freedom of movement: About 1 m of space for people is
required around all sides of the machine.
Lighting for work: min. 300 lux.

switch on the rotating handle for controlling the speed.
Only operate the BRB Electric if the electrical safety equipment/restart
inhibitor is working.
1.5 Supervised operation
Workshop application: The workshop manager is responsible for safety in
the danger zone around the machine and should allow only qualified
personnel to enter the zone or operate the machine.
Outdoor/field application: The site manager is responsible for safety in the
danger zone around the machine and should allow only qualified personnel
to enter the zone or operate the machine.

2.7.2 "NC" clamping system
The new "NC" clamping system, with its clamping wedges firmly anchored in
the mandrel, is ideal for applications where no foreign bodies may enter the
inside of the pipe or a container. The "NC" clamping system provides extra
safety particularly for vertical work. The clamping wedges can be quickly
replaced.
