Electrical Safety Instructions
These pages are accurate at the time of printing. In the constant effort to improve, however, we may
make changes to the electrical systems of future machines. Study this section carefully. If you see
differences between your machine and what is shown in this section, call Technical Support at (360)
734-1540 for assistance BEFORE making any changes to the wiring on your machine.
Shock Hazard: It is extremely dangerous to
perform electrical or wiring tasks while the
machine is connected to the power source.
Touching electrified parts will result in
personal injury including but not limited to
severe burns, electrocution, or death. For
your own safety, disconnect machine from
the power source before servicing electrical
components or performing any wiring tasks!
Wire Connections: All connections must be
tight to prevent wires from loosening during
machine operation. Double-check all wires
disconnected or connected during any wiring
task to ensure tight connections.
Modifications: Using aftermarket parts or
modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.
Motor Wiring: The motor wiring shown in these
diagrams is current at the time of printing,
but it may not match your machine. Always
use the wiring diagram inside the motor
junction box.
Circuit Requirements: Connecting the machine
to an improperly sized circuit will greatly
increase the risk of fire. To minimize
this risk, only connect the machine to a
power circuit that meets the minimum
requirements given in this manual.
Capacitors/Inverters: Some capacitors and
power inverters store an electrical charge for
up to 10 minutes after being disconnected
from the power source. To reduce the risk of
being shocked, wait at least this long before
working on capacitors.
Wire/Component Damage: Damaged wires
or components increase the risk of serious
personal injury, fire, or machine damage. If
you notice that any wires or components are
damaged while performing a wiring task,
replace those wires or components before
completing the task.
Experiencing Difficulties: If you are
experiencing difficulties understanding the
information included in this section, contact
our Technical Support at (360) 734-1540.
