This manual provides critical safety instructions on the proper setup,
operation, maintenance and service of this machine/equipment.
Failure to read, understand and follow the instructions given in this
manual may result in serious personal injury, including amputation,
electrocution or death.
The owner of this machine/equipment is solely responsible for its safe

tion in a safe environment, personnel training and usage authoriza-
tion, proper inspection and maintenance, manual availability and
comprehension, application of safety devices, blade/cutter integrity,
and the usage of personal protective equipment.
The manufacturer will not be held liable for injury or property
damage from negligence, improper training, machine modifications or

Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks, cement and other masonry products.
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.

W1738 sander, you will have to install a phase converter.
When using a phase converter, the power from the manu-
factured power leg (sometimes called the wild wire) can
fluctuate. Connect the manufactured power leg to the
terminal to prevent damage to the transformer. The wire
from the terminal can handle some fluctuation because
it goes directly to the motor. The power going to the and
terminals goes to the transformer and must not fluctuate
to prevent damage.

When selecting sandpaper, keep in mind that the Model
W1737/W1738 accepts only 37" wide x 60" long belts.
Consider the type of work, the species of wood and
the stage of finishing. When choosing which sandpaper
to use, use these grit numbers as a general guide to
sandpaper type:

•80-100Grit ............................Medium

 For best results, do not increase grit numbers
