GROUNDING INSTRUCTIONS
WARNING
Improper connection of equipment grounding conductor
can result in the risk of electrical shock.
• The machine should be grounded while in use to protect
operator from electrical shock.
• In the event of an electrical short circuit, grounding
reduces the risk of electrical shock by providing an
escape wire for the electric current.
• This machine is equipped with an approved
3-conductor cord rated at 150V and a 3-prong
grounding type plug for your protection against shock
hazards.
In Canada, the use of temporary adapter is not permitted
by the Canadian Electric Code. Where permitted, the rigid
green tab or terminal on the side of the adapter must be
securely connected to a permanent electrical ground such
as a properly grounded water pipe, a properly grounded
outlet box or a properly grounded wire system.
