SAFETY
iii iii
POWER WAVE 450
FOR ENGINE
powered equipment.
7.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
7.b.Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
7.c. Do not add the fuel near an open flame
welding arc or when the engine is run-
ning. Stop the engine and allow it to cool
before refueling to prevent spilled fuel
from vaporizing on contact with hot
engine parts and igniting. Do not spill
fuel when filling tank. If fuel is spilled,
wipe it up and do not start engine until
fumes have been eliminated.
7.d. Keep all equipment safety guards, covers
and devices in position and in good
repair. Keep hands, air, clothing and
tools away from V-belts, gears, fans and
all other moving parts when starting,
operating, or repairing equipment.
7.e. In some cases it may be necessary to remove safety guards
to perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.
7.f. Do not put your hands near the engine fan. Do not attempt
to override the governor or idler by pushing on the throttle
control rods while the engine is running.
7.g. To prevent accidentally starting gasoline engines while turn-
ing the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.
7.h. To avoid scalding, do not remove the
radiator pressure cap when the engine
is hot.
ELECTRIC AND MAGNETIC
FIELDS
may be dangerous
8.a. Electric current flowing through any conductor causes local-
ized Electric and Magnetic Fields (EMF). Welding current cre-
ates EMF fields around welding cables and welding
machines.
8.b. EMF fields may interfere with some pacemakers, and welders
have a pacemaker should consult their physician before
welding.
8.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
8.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
8.d.1. Route the electrode and work cables together -
Secure them with tape when possible.
8.d.2. Never coil the electrode lead around your body.
8.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.
8.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.
8.d.5. Do not work next to welding power source.
