SAFETY — Continued
GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the
operator from electric shock. The compressor is equipped with
a three-conductor cord and three-prong grounding type plug to
fi t the proper grounding type receptacle. The green (or green
and yellow) conductor in the cord is the grounding wire. Never
connect the green (or green and yellow) wire to a live terminal. If
your unit is for use on less than 150 volts, it has a plug that looks
like that shown in sketch (A) in Figure on the right. An adapter, see
sketches (B) and (C), is available for connecting sketch (A) type
plugs to two-prong receptacles. The green-colored rigid ear, lug,
or the like extending from the adapter must be connected to a
permanent ground, such as a properly grounded outlet box.
NOTE: The grounding adaptor, sketch (C), is prohibited in
Canada by Canadian Electrical Code Part 1. Therefore,
the instructions for its use are not applicable in Canada.
We recommend that you never disassemble the compressor or
try to do any rewiring in the electrical system. Any repairs should
be performed only by metabo HPT Service Centers. Should you
be determined to make a repair yourself, remember that the green
colored wire is the “grounding” wire. Never connect this green
wire to a “live” terminal. If you replace the plug on the power cord,
be sure to connect the green wire only to the grounding (longest)
prong on a 3-prong plug.
If in doubt, call a qualifi ed electrician and have the receptacle
checked for ground.
EXTENSION CORD
Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacles that accept
the compressor’s plug. Replace or repair damaged cord.
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. Table shows the correct size to use depending on cord length and name plate ampere rating. If in doubt, use
the next heavier gage. The smaller the gage number, the heavier the cord.
