SELECT SUITABLE LOCATION

The Power Wave ® S500 will operate in harsh environ-
ments. Even so, it is important that simple preventative
measures are followed in order to assure long life and
reliable operation.
• The machine must be located where there is circula-
tion of clean air.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum. The use of air filters on
the air intake is not recommended because normal
air flow may be restricted. Failure to observe these
precautions can result in excessive operating tem-
peratures and nuisance shutdown.
• Keep machine dry. Shelter from rain and snow. Do
not place on wet ground or in puddles.
• Do not mount the Power Wave
bustible surfaces. Where there is a combustible sur-
face directly under stationary or fixed electrical equip-
ment, that surface shall be covered with a steel plate
at least .060" (1.6mm) thick, which shall extend not
less than 5.90" (150mm) beyond the equipment on all
sides.

LIFTING

Both handles should be used when lifting Power
Wave ® S500. When using a crane or overhead device
a lifting strap should be connected to both handles. Do
not attempt to lift the Power Wave
sories attached to it.

INSTALLATION

• Be sure machine is stable when lifting.
• Do not operate machine while suspended when
lifting.
