phenol. Be aware that extended tip-contact may result in their
deterioration. lRemove the collected solder scrap regularly.
The angle of the front opening can be

WARNING
CAUTION
lHigh temperatures. Handle with care. lTo avoid injury, do not
touch the metal part of the stand. lTo prevent fire, do not use the
ST-21 near flammable substances.
lAlways place the stand on a stable worktable, or other stable
location, to prevent injury or accident from dropping it. lTo avoid
splattering solder scrap, do not swipe the tip of the iron across
the brass wool. This is dangerous. lTo prevent fire or personal
injury, be sure that the stand has cooled sufficiently before
storing it.

3Rules for Safe Operation
1. DO NOT USE IN DANGEROUS ENVIRONMENTS.
Do not use the soldering station in damp or wet locations or expose it to
external environmental conditions, particularly rain. Never use it in an explosive
atmosphere. The heat from the heater can ignite fumes. Be sure that the work area
is well ventilated.
2.
KEEP CHILDREN AND BYSTANDERS AWAY FROM THE SOLDERING STATION.
Do not let bystanders touch the soldering station. All bystanders should be kept a
safe distance from the work area.
3. USE FOR THE RIGHT JOB.
Your soldering station is an electrical tool used to solder parts and melt solder. Do
not use the soldering station for any other purpose. For example: The soldering
station should never be used to warm water or other liquids.
4. WEAR PROPER APPAREL, SAFETY GLASSES, GLOVES AND MASK.
Do not wear loose clothing (such as a necktie). Tie up long hair. Clothing or hair
can burn on contact with the tip or surrounding heated parts.
5. CONNECT TO THE SPECIFIED AC POWER SUPPLY.
The power voltage for this soldering station is indicated at the back of the control
unit. Never plug the soldering station into any other voltage.
6. DO NOT ABUSE THE POWER CORD AND INSPECT IT PERIODICALLY.
Never carry your soldering station by its power cord or yank the power cord to
disconnect it from the receptacle. Keep the power cord away from heat, oil and
sharp edges.
WARNING
The RX-802AS is an anti-static model. Be sure to
properly ground the soldering station using a grounded
receptacle to prevent electric shocks and anti-static. If
it is not properly grounded, electric shocks will occur. As
the soldering station uses conductive materials, please
be careful not to touch any electrical power source or a
serious injury will result.

7. USE STAND PROVIDED.
Be sure to use the ST-21 soldering iron stand included with the soldering station.
If this stand is not used, the plastic parts (adapter ring and/or handpiece) of the
soldering iron unit could be damaged. Position the soldering iron stand on a flat
work-surface or bench.
8. CONCERNING THE TIP.
After turning OFF the power switch, allow the tip to cool naturally. Never use any
other method to cool it down. For example: Water should never be poured or
sprinkled on the tip to cool it down.
9. CONCERNING THE POWER CORD.
IF THE POWER CORD IS DAMAGED THEN THE SOLDERING STATION SHOULD BE
RETURNED TO THE DISTRIBUTOR FOR REPLACEMENT.

NOTE ) If nothing is pressed for 30seconds during setting the temperature, the
temperature on display will be recorded and the display will return to the normal
conditions.
*The set temperature should be set at 50°C(90˚F) higher than the sleep
temperature (see the section 4-4), otherwise you will not be able to set
the set temperature value. (Example: If the set temperature is set at
200°C(392˚F), the sleep temperature must be 150°C(302˚F) or under.
