1.5 Safety – Considerations Under Normal Operation
Work on electrical parts of the machine must be preformed by a
qualified electrician or
by experienced persons under the supervision of a qualified
electrician.
ALWAYS INFORM OPERATING PERSONNEL before starting any
special work or maintenance work! When work is carried out that
affects the machine's operations or settings and/or the settings of the
safety devices, complete compliance with this instruction manual is
necessary! This is an important part of the Lock Out/Tag Out
procedure mentioned below.
LOCK OUT/TAG OUT or “Maintenance Mode” of a machine.
The machine must be in a “safe” mode when troubleshooting,
adjusting or maintaining the equipment. The machine state is "safe” to
work on when it is unable to endanger anyone, i.e. no stored energy
that might be released is present. Examples would include:
 Electrically the Main switch is disconnected, locked out and tagged
out.
 Mechanically the machine and all parts of it are secure i.e. lids
cannot fall, wheels cannot roll, etc.
 Any other “stored energy”, such as a spring under tension has been
neutralized.
Before switching the machine ON, ensure no one can be endangered
when the machine starts up!
Check to ensure that the machine power switch is in the off position
before attempting to plug the machine into the main power source!
Make sure that the power plug and receptacle are compatible and that
they fit securely together. If they do not securely fit together, do not
operate the machine!
The machine MUST be connected to an approved dust collector such
as a Blastrac® 4-54DC99, 6-54DC99 or 8-54DC99 when in operation.
NEVER turn off or disconnect the dust collector when the machine is
running!
Always empty the dust container of the dust collector properly.
Comply with waste disposal regulations. If you are unsure of current
regulations contact your local authority. Always dispose of materials
and supplies safely to protect the environment.

1.5 Safety – Considerations Under Normal Operation (cont’d)
AVOID DANGEROUS SITUATIONS
•Survey the work area before starting the machine for hidden
obstructions and uneven cracks or joints.
•Do not expose the machine to rain.
•Do not use the machine in standing water conditions.
•Keep work area well lit.
•Do not allow the machine to cross over the edge of the
concrete slab or work surface.
•When working on uneven surfaces, pay attention not to cross
over embedded floor anchors, ledges, or heaved slab joints as
this may lead to machine damage, personal injury, or both.
Check the system thoroughly after each transport and at least once a
day for external damage and defects. As defects or problems are
found qualified personnel MUST correct them immediately.
In the event of an emergency, the operator should execute an
Emergency Stop! A Lock Out/Tag Out or “Maintenance Mode” is
necessary in the event of an emergency!
How to Execute an Emergency Stop:
9Operate the Emergency Stop Pushbutton located on the control panel of
the scarifier or, for those machines equipped with a gasoline motor,
activate the dead-man safety switch by pulling the rope. This will remove
all power from the machine.
9Operate the mechanical quick lift actuator on the scarifier. This will remove
the scarifier drum from the work surface.
9Switch the dust collector to the off position.
9Wait until all drives come to a complete stop!
9Disconnect the main power plugs or lock out the main disconnect switches
of both machines to ensure that no power is being fed to the scarifier or
the dust collector.

1.6Electrical Safety
When extending the main cable, use only extension cables that
are dimensioned in accordance with the machine's total output
and with current regulations.
DO NOT ABUSE THE POWER CORD! Never pull the machine by
the cord! Never allow the cord to be run over by a forklift truck
or any other vehicle! Connect the power cord to the power
source and power cable extensions with approved plugs only
and with the machine power switch turned off.
To protect against unnecessary damage, ensure that no
vehicles, such as forklift trucks, can drive over the electrical
cable or the dust hose!
Electrical components must be checked on an ongoing basis.
Electrical cables, enclosures, and safety devices should be
inspected prior to every shift, EVERY day. Always inspect after
transport. A thorough check of the internal terminations should
be accomplished every 3 months.
If defects are found or suspected, contact a qualified electrician
or your Blastrac representative. Defects such as loose
connections or scorched cables must be corrected immediately.
Ensure reliability of voltmeters used for troubleshooting.

3.3 Mechanical Operating Elements
Quick Lift Actuator:
The BMP-G/E250-X scarifiers have a quick lift actuator for the scarifier drum
(See Figure 3.1, Item 2).
The quick lift actuator can be used to lift the scarifier drum without altering the
scarifier depth setting, to transport or move the scarifier or in an emergency
situation.
Depth Setting Adjustment:
Turn the depth setting adjustment wheel or hand wheel to set the scarifier depth
so that the individual scarifier cutters bit correctly (scratch) and the desired
surface profile is obtained. The depth setting adjustment enables the scarier
cutters to be set as deep as required on the surface to be treated.
The scarifier depth should only be set “deep” enough so that the scarifier cutters
are thrown up without obstruction through centrifugal force and can turn freely on
their individual shaft. If the depth setting has been set correctly, the scarifier will
run smoothly and evenly.
3.4 Scarifier Drum Details
The scarifier drum is the heart of the scarifier. The scarifier drum has a very
simple structure. The individual scarifier cutters are slid onto their individual shaft
with spacer washers as shown in the enclosed assembly plan. The washers
ensure that there is sufficient clearance between the scarifier cutters.
The enclosed component-mounting diagram takes into account a required lateral
play of approximately 1-3mm for the scarifier cutters.
