Keep the work area clean and well a.
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
Keep bystanders, children, and b.
visitors away while operating the
regulator. Distractions are able to
result in the loss of control of the
regulator.
Personal safety
Stay alert. Watch what you are do-a.
ing and use common sense when
operating the regulator. Do not
use the regulator while tired or un-
der the inuence of drugs, alcohol,
or medication. A moment of inatten-
tion while operating the regulator in-
creases the risk of injury to persons.
Avoid unintentional starting. Be b.
sure the tool switch is off before
connecting to the CO2 Regulator.
Do not connect the tool to the CO2
Regulator with the switch on.
c. Always wear eye protec-
tion. Wear ANSI-approved safety goggles.
d. Always wear hearing
protection when using
the regulator. Prolonged
exposure to high intensity
noise is able to cause hearing loss.
Do not use the regulator if the f.
Regulator Control Knob does not
function properly. Any regulator that
cannot be controlled is dangerous
and must be repaired.
Disconnect the tool from the COg.
Regulator before making any adjustments, changing accessories,
or storing the tool. Such preventive
safety measures reduce the risk of
starting the tool unintentionally. Turn
off and detach the CO2 supply, safely
discharge any residual pressure, and
release the throttle and/or turn the
switch to its off position before leaving the work area.
Store the regulator and gas canis-h.
ter when idle out of reach of children and other untrained persons.
A regulator is dangerous in the hands
of untrained users.
Do not exceed 150 PSI input pres-i.
