GAW-135H — INSTALLATION
Outdoor Installation
Install the generator/welder in a area that is free of
debris
,
bystanders
, and
overhead obstructions
. Make sure the
generator is on secure level ground so that it cannot slide or
shift around. Also install the generator in a manner so that
the exhaust will not be discharged in the direction of nearby
homes.
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
Indoor Installation
Exhaust gases from gasoline engines are extremely
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any gasoline engine
are very poisonous if discharged in a closed room, but
harmless if allowed to mix with the outside air. If the generator
is installed indoors, you must make provisions for venting
the engine exhaust to the outside of the building.
Generator Grounding
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good
EARTH
ground. Always use the ground terminal on the generator to
ground the generator.
Article 250 (Grounding) of the National Electrical Code (NEC)
provides guide lines for proper grounding and specifies that
the cable ground shall be connected to the grounding system
of the building as close to the point of cable entry as
practical.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm
2
) or larger.
b. Aluminum - 8 AWG (8.4 mm
2
) or larger.
2. When grounding the generator (Figure 3) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the other
end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried a minimum of 8 ft. into the ground.
Mounting
The generator should always be mounted on a flat level
surface to isolate vibration of the generator when it is
running.
DO NOT
place the generator on slopes, the
possibility exists that the generator could slide.
Pay close attention to ventilation when
operating the generator inside tunnels and
caves. The engine exhaust contains
noxious elements.

CAUTION
An electric shock is apt to happen
when vibrators are used. Pay close
attention to handling when operating
vibrators and always use rubber
boots and gloves to insulate the
body from a short circuit.
