INJURY OR DEATH. KEEP CHILDREN AWAY. 

PACEMAKER WEARERS SHOULD CONSULT WITH

THEIR DOCTOR BEFORE OPERATING.

Read and understand the following safety highlights. For

additional safety information, it is strongly recommended 

that you purchase a copy of “Safety in Welding & Cutting - 

ANSI Standard Z49.1” from the American Welding Society, 

P.O. Box 351040, Miami, Florida 33135 or CSA Standard 

W117.2. A Free copy of “Arc Welding Safety” booklet E205

BE SURE THAT ALL INSTALLATION, OPERATION,

MAINTENANCE AND REPAIR PROCEDURES ARE

PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE POWERED

EQUIPMENT.

1.a. Turn the engine off before troubleshooting

and maintenance work unless the
maintenance work requires it to be running.

1.b. Operate engines in open, well-ventilated areas or vent the engine

exhaust fumes outdoors.

arc or when the engine is running. Stop the
engine and allow it to cool before refueling to
prevent spilled fuel from vaporizing on contact

tank. If fuel is spilled, wipe it up and do not start engine until
fumes have been eliminated.

1.d.  Keep all equipment safety guards, covers

and devices in position and in good repair.
Keep hands, hair, clothing and tools away 
from V-belts, gears, fans and all other 
moving parts when starting, operating or
repairing equipment.

1.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.

1.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.

1.g. To prevent accidentally starting gasoline engines while turning

the engine or welding generator during maintenance work,
disconnect the spark plug wires, distributor cap or  magneto wire
as appropriate.

1.h. To avoid scalding, do not remove the radiator

pressure cap when the engine is 

hot.

MAGNETIC FIELDS MAY

BE DANGEROUS

before welding.

which are now not known.

2.d. All welders should use the following procedures in order to

2.d.1. Route the electrode and work cables together - Secure

them with tape when possible.

2.d.2. Never coil the electrode lead around your body.
2.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.

2.d.4. Connect the work cable to the workpiece as close as pos-

sible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

Safety 02 of 04 - 10/08/2021

1.c. Do not add the fuel near an open flame welding

with hot engine parts and igniting. Do not spill fuel when filling

2.a. Electric current flowing through any conductor

Welding current creates EMF fields around welding cables

2.b. EMF fields may interfere with some pacemakers, and

2.c. Exposure to EMF fields in welding may have other health effects

minimize exposure to EMF fields from the welding circuit:

1.i. Using a generator indoors CAN KILL YOU IN

MINUTES.

1.j. Generator exhaust contains carbon monoxide. This is a poison

you cannot see or smell.

1.k.  NEVER use inside a home or garage,

EVEN IF doors and windows are open.

1.l.   Only use OUTSIDE and far away from

windows, doors and vents.

1.m. Avoid other generator hazards. READ

MANUAL BEFORE USE.
