22. Maintenance. For your safety, maintenance should be performed by a qualified technician.
23. Use proper size and type extension cord. If an extension cord is required, it must be of
the proper size and type to supply the correct current to the tool without heating up.
Otherwise, the extension cord could melt and catch fire, or cause electrical damage to
the tool. See the chart below for appropriate extension cord size. Longer extension
cords require larger size wire. If you are using the tool outdoors, use an extension cord
rated for outdoor use (signified by “WA” on the jacket).
Note: Performance of this tool (if powered by line voltage) may vary depending on
variations in local line voltage. Extension cord usage may also affect tool performance.
Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be understood
by the operator that common sense and caution are factors which cannot be built into
this product, but must be supplied by the operator.
