Installation - Ryobi MMA-140 Owner's Operating Manual

24. If, in an emergency, it must be disconnected,
guard against shock burns, or flash from switch
arcing. Always shut OFF and disconnect all
power to equipment. Power disconnect switch
must be available near the welding power
source.
25. Fully insulated electrode holders should be
used. Do NOT use holders with protruding
screws or with any form of damage.
ENVIRONMENT
These units are designed for use in environments
with increased hazard of electric shock.
A. Examples of environments with increased
hazard of electric shock are:
1. In locations in which freedom of movement is
restricted, so that the operator is forced to
perform the work in a cramped (kneeling,
sitting or lying) position with physical contact
with conductive parts.
2. In locations which are fully or partially limited
by conductive elements, and in which there is
a high risk of unavoidable or accidental contact
by the operator.
3. In wet or damp hot locations where humidity
or perspiration considerable reduces the skin
resistance of the human body and the
insulation properties of accessories.
B. Environments with increased hazard of electric
shock do not include places where electrically
conductive parts in the near vicinity of the
operator, which can cause increased hazard,
have been insulated.
LOCATION
This machine can operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reli-
able operation:
• This machine must be located where there is
free circulation of clean air without restrictions
for air movement to and from the air vents. Do
not cover the machine with paper, cloth or rags
when switched on.
ADDITIONAL SAFETY INSTRUCTIONS

INSTALLATION

26. Fully insulated lock-type connectors should be
used to join welding cable.
27. Frequently inspect cables for wear, cracks and
damage. IMMEDIATELY REPLACE those with
excessively worn or damaged insulation to
avoid possibly lethal shock from bared cable.
Cables with damaged areas may be taped to
give resistance equivalent to original cable.
Keep cable dry, free of oil and grease, and
protected from hot metal and sparks.
• Dirt and dust that can be drawn into the
machine should be kept to a minimum.
• This machine has a protection rating of IP21S.
Keep it dry and do not place it on wet ground
or in puddles. Do not use in wet or damp
locations. Store indoors.
• Locate the machine away from radio controlled
machinery. Normal operation may adversely
affect the operation of nearby radio controlled
machinery, which may result in injury or
equipment damage.
Read the section on electromagnetic compatibility
in this manual.
• Do not operate in areas with an ambient
temperature greater than 40°C.
TILTING
Place the machine directly on a secure, level
surface.
Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal.
The machine may topple over if this procedure is
not followed.
VENTILATION
This cutting machine can create powerful cutting
current and has strict cooling requirements that
cannot be met with natural ventilation. Therefore
the built-in fan is very important in enabling the
machine to work stable with effective cooling. The
operator should make sure that the louvers be
uncovered and unblocked. The minimum distance
between the machine and nearby objects should
be 25cm.
