EXTENSION CORDS
Use only a 3-wire extension cord that
has a 3-blade grounding plug, and a 3-
slot receptacle that accepts the plug
from the product. When using an ex-
tension cord, be sure to use one heavy
enough to carry the current your prod-
uct draws.

For lengths less than 130 ft, No. 14
AWG extension cords shall be used.
For lengths less than 200 ft, No. 12
AWG extension cords shall be used.
An undersized cord results in an drop
in line voltage and loss of power and
overheating. Do not use damaged ex-
tension cords. Examine extension cord
before using and replace if damaged.
Do not abuse extension cord and do
not yank on any cord to disconnect.
Keep cord away from heat and sharp
edges. Always disconnect the exten-
sion cord from the receptacle before
disconnecting the product from the ex-

English
chine is being operated (by cordoning
off the area).
Do not touch/hold the nozzle or the dry

DANGER
Risk of suffocation on account of car-
bon dioxide. The dry ice pellets are
made of solidified carbon dioxide. The
carbon dioxide content in the air at the
place where the machine is used will
increase when the machine is running.
Ensure adequate ventilation at the
place of use; if possible, use an alarm
to warn persons. Symptoms of high
levels of carbon dioxide in the air that is
breathed in:
3...5%: headache, faster breathing.
–
7...10%: headache, nausea and
–
perhaps even unconsciousness.
If any of these symptoms occur, please
switch off the machine immediately and
get a breath of fresh air; improve the
ventilation before starting work again
with the machine or use respirators.
Follow the safety specifications of the
manufacturer of dry ice.
DANGER
Risk of injury on account of electro-
static discharge; risk of damage to the

remains intact during the entire clean-
ing process.
