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.

environment where electric shock is possible.
