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.

____________________________________________________

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

welding  arc  or  when  the  engine  is  running.
Stop  the  engine  and  allow  it  to  cool  before
refueling to prevent spilled fuel from vaporiz-
ing  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.

____________________________________________________

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.

SAFETY

i

ARC WELDING CAN bE HAzARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIbLE SERIOUS 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 W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available
from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

bE  SURE  THAT  ALL  INSTALLATION,  OPERATION,  MAINTENANCE  AND  REPAIR  PROCEDURES  ARE
PERFORMED ONLY bY QUALIFIED INDIVIDUALS.

WARNING

ELECTRIC AND 
MAGNETIC FIELDS
may be dangerous

2.a.  Electric  current  flowing  through  any  conductor  causes 

localized  Electric  and  Magnetic  Fields  (EMF).  Welding 
current  creates  EMF  fields  around  welding  cables  and 
welding machines

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

welders  having  a  pacemaker  should  consult  their  physician
before welding.

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

effects which are now not known.

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

minimize  exposure  to  EMF  fields  from  the  welding  circuit:

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

possible to the area being welded.

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

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

radiator pressure cap when the engine is
hot.
