WARNING
SAFETY PRECAUTIONS
SELECT SUITABLE LOCATION
In order to assure long life and reliable operation,
the owner of this machine should follow these sim-
ple preventative measures:
• The machine must be located where there is free cir-
culation of clean air such that air movement in the
back, out the sides and bottom will not be restricted.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum. Failure to observe
these precautions can result in excessive operating
temperatures and nuisance shutdown.
• Keep machine dry. Shelter from rain and snow. Do
not place on wet ground or in puddles.
• DO NOT MOUNT OVER COMBUSTIBLE SURFACES.
Where there is a combustible surface directly under
stationary or fixed electrical equipment, that surface
shall be covered with a steel plate at least .06”(1.6mm)
thick, which shall extend not less than 5.90”(150mm)
beyond the equipment on all sides.
STACKING
POWER WAVE 355/405 cannot be stacked.
TILTING
Place the machine directly on a secure, level surface
or on a recommended undercarriage. The machine
may topple over if this procedure is not followed.
