BC 60 "Trailblazer" Brushcutter SAFETY
OCT/2012 (49458202) Section 1-3
SAFETY WHILE STARTING THE
MACHINE
NORDCO recommends the use of a
Command position. This means that the
machine is never running unless someone
is at or near the main control panel. To
prevent injury to personnel or damage to
the machine, it is highly recommended to:
1. Only start and operate the machine
from the operator’s seat.
2. Use the “STARTUP Checklist” to
check the machine controls and
gauges to make certain all
systems are operating correctly.
SAFETY WHILE
OPERATING/TRAVELING
1. Never operate the machine when
people are within 800 feet of the
machine. It is also suggested that this
distance be maintained for livestock,
houses, building, cars, and highways
or other roads.
2. Never operate the machine in areas
when people may be hidden from view,
near crossings, or in double track
territory. If you must operate in double
track territory, always keep a lookout
for approaching trains and section
crews, etc.
3. Continuously be on the lookout for
hidden, immovable objects such as
rocks, boulders, concrete, etc. Contact
with such objects may cause severe
damage to the machine as well as
pose a hazard to those in the vicinity if
the cutter blades come loose and
become airborne projectiles. NOTE:
Blades or teeth could travel in excess
of 250 mph if they should come loose
from the cutter head.
4. Never allow more riders than seats and
seatbelts allow. This machine was
designed to be operated by two
people.
5. The machine is to be operated from
the Operator’s seats only. Do NOT
stand and operate this machine.
6. Press the EMERGENCY STOP
pushbutton on the center control
console in emergencies and potentially
dangerous situations.
7. If personnel or bystanders are near the
machine during operation, give a
warning signal using the air horn. If
they fail to respond to this warning,
stop operation immediately.
8. Slow down the work cycle and use
slower travel speeds in congested or
populated areas.
9. Halt work if visibility is poor. Strong
rains, fog, and extremely dusty
conditions can affect visibility in your
work area. Wait for the weather to
improve before continuing work.
10. Take extreme care when storing or
removing cutter booms from their
cradle. Avoid contact with the
machine.
11. Cutter booms MUST be stored and
locked in their cradles during travel.

LOCKOUT-TAGOUT PROCEDURES
NORDCO has provided the means to lockout this machine. NORDCO cannot be held
responsible for injury caused by failure to comply with your company’s Lockout/Tagout
Procedures.
The following procedures are designed to lead the operator through the steps required to shut the machine
down and prepare it for performing mechanical maintenance work. These procedures are intended to release
potentially dangerous stored energy forms and make the machine safe to begin repairs. It is your company’s
responsibility to Lockout/Tagout Procedures based on this list, train you in their proper and safe use, and to
periodically inspect your work area to verify that you are complying with the procedures. Lockout/Tagout
Procedures must be followed!
SAFETY PROCEDURES
LOCKOUT/TAGOUT
1. Apply the Electrical Interlock/Warmup.
2. Chock wheels to prevent accidental rolling of machine on grade.
3. If you have not already done so, determine which components are to
have maintenance. Place all machine mechanical systems or workheads
in the full up and locked positions.
4. When mechanical locking up of equipment is not feasible for
maintenance lower the component to the ground prior to working on the
equipment.
5. Turn the ignition switch to the OFF position. This turns off the power to
the control circuits on the machine. Place a TAGOUT card in close
proximity to the ignition switch.
6. Turn the battery disconnect switch (BDS)to the OFF position.
a. For machines with the BDS on the left side of the center (front)
control console: Place a TAGOUT card on the switch after you
have switched it to the OFF position.
b. For machines with a remotely located BDS (usually next to the
battery box itself): Close the cover to the disconnect switch and
place a LOCKOUT lock on the box after you have switched it to
the OFF position.
7. Bleed off hydraulic pressure by slowly cracking hose fitting (1/8-1/4 of
turn CCW) at the cylinder/motor/pump of the hydraulic circuit being
worked on. Service or perform maintenance on circuit after the steady
flow of oil is gone.
8. Follow all of your company’s lockout/tagout rules before proceeding.
Note: When working on machine components, be aware that moving
components during repairs may create energy (ie., moving a hydraulic
cylinder). Proper precautions should be taken.
