EXTENSION CORDS
Use proper extension cords. Make
sure your extension cord is in good condition and is a
3-wire extension cord which has a 3-prong grounding
type plug and matching receptacle which will accept
the machine’s plug. When using an extension cord,
be sure to use one heavy enough to carry the current
of the machine. An undersized cord will cause a
drop in line voltage, resulting in loss of power and
overheating. Fig. C shows the correct gauge to use
depending on the cord length. If in doubt, use the
next heavier gauge. The smaller the gauge number,
the heavier the cord.

UNPACKING AND CLEANING
Carefully unpack the machine and all loose items from the shipping container(s). Remove the rust-preventative oil from
unpainted surfaces using a soft cloth moistened with mineral spirits, paint thinner or denatured alcohol.
Do not use highly volatile solvents such as gasoline, naphtha, acetone or lacquer thinner for cleaning your machine.
After cleaning, cover the unpainted surfaces with a good quality household floor paste wax.
