 CAUTION

When power is ON, tip temperatures will be between 200° and 450°C. (392° to 840°F.)
To avoid injury or damage to personnel and items in the work area, observe the
following:

Do not touch the tip or the metal parts near the tip.

Do not allow the tip to come close to, or touch, flammable materials.

Inform others in the area that the unit is hot and should not be touched.

Turn the power off when not in use, or left unattended.

Turn the power off when changing parts or storing the Hakko 941.

 CAUTION

To prevent accidents or damage to the Hakko 941, be sure to observe the following:

Do not use the Hakko 941 for applications other than soldering.

Do not allow the Hakko 941 to become wet, or use it when hands are wet.

Do not modify the Hakko 941.

Use only genuine Hakko replacement parts.

Do not bend or damage the control card. If the card does become damaged, do not force the
card into the station slot.

Do not strike the iron against hard objects to remove excess solder. This will damage the
iron.

Remove power and iron cords by holding the plug – not the wires.

Be sure the work area is well ventilated. Soldering produces smoke.

The Hakko 941 is not intended for use by children or infirm persons without supervision.

Children should be supervised to ensure that they do not play with the Hakko 941.

Note:

  The model Hakko 941 station is not available for sale or use in the United States.
