will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension
to make up the total length, be sure each individual
extension contains at least the minimum wire size. The
following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use
the next heavier gauge. The lower the gauge number, the
heavier the cord.

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
WARNING: To reduce the risk of personal injury,
