This product uses a catalytic gas reaction
system.The special catalyst contained in the
tip is preheated with a butane flame.The
preheated flame is extinguished when the
shutter is closed over the ignition vent.
Butane gas continues to flow over the
preheated catalyst generating infrared heat
which is either conducted through the soldering
iron tip or passed through the heat tip as hot gas.

WARNING:
This product, when used for soldering and similar applications, produces chemicals
known to the State of California to cause cancer and birth defects or other reproductive harm.
WARNING: The Department of Transportation Hazardous material Regulations forbid the car-
riage of butane or other flammable gas products on passenger aircraft. Do not pack this item
or any other flammable gas item, in any checked or carry-on baggage.
To reduce the risk of injury or property damage, READ AND UNDERSTAND the following warnings:
1. To prevent fire or damage to
work surfaces, be sure hot air
exhaust opening is positioned
up.Hot air comes out of the
exhaust opening in the tip.Keep
combustibles and hands away
from the opening.
2. To prevent fuel tank leakage, do
not store in environmental area
that exceeds 104°F/40°C (such
as car dashboard or trunk, direct
sun, glove compartment, or other
enclosed, unventilated areas).
3. Be sure to turn “ON/OFF” switch
to “OFF” after use.
4. Do not perform maintenance or
repair unless unit is completely
cool. Be certain “ON/OFF” lever
is “OFF”.
5.
Wait for tips to cool before changing.
Keep hands and combustibles
from tip area while in use.
6. When soldering or desoldering
always review material safety
data sheets (MSDS) for recommended precautions for safe
handling and use of solder, solder paste, flux, conformal coatings and any other chemicals.
7. Store away from, and do not
use in the presence of children.
8.
Keep protective cap on unit while
not in use.
9. Use only in well-ventilated
area. Continuous or extended
use indoors should be done
only with a local exhaust
ventilation to the outside.
10.
Do not expose to open flame or
other sources of high temperature.
11. To prevent clouding of window,
do not use alcohol or alcoholbased cleaner.
12. Use only Master Appliance
Ultratane Butane Fuel to insure
maximum safety and performance. MSDS upon request.
13. Always use safety glasses or
goggles.
14. Do not fill gas or store near
open flame, heater, furnace or
combustible materials.
15. Do not misuse, abuse, alter
or tamper.
16. It is your responsibility to follow
your governmental regulations
when disposing of this unit.
NOTE: When operating in
extremes of temperature (hot or
cold), at high altitude, ignition may
be difficult due to the variation of
gas pressure caused by these
extremes. Gas control settings will
also be affected and will vary from
those under normal conditions.
If difficulties are experienced,
please contact our Customer
Service Department who will
advise on adjustment.
Warnings:
2. Push ignition

Problem
Does not ignite
Does not flame off
Tip does not heat up
Probable cause
a. Empty tank
b. Clogged ejector
c.
Too high or too low gas pressure
d. Damaged burner
When make a low roaring sound,
the flame is not turned off
a. Used-up catalyst
b. Insufficient gas pressure
Solution
a. Refill with butane fuel
b.
Replace with new ejector
c.
Adjust gas open/close knob
d.
Replace with new burner
Turn the shutter lever again
and hold for 3 seconds
a. Replace with new tip
b. Refill with butane gas
1. Allow unit to cool and put protective cap
on for storage.
2. If your unit is not going to be used for
awhile, store in the following manner.
Store in proper location avoiding elevated
temperatures and away from children.
3. Leave tank approximately 1/2 full so
lubrication of fuel pickup filter stays wet.
4. Set flow control valve at setting X.
How to Empty Tank of Butane Gas if Needed
1. Only empty fuel tank in a well
ventilated area and away from
ignition sources. Remember
butane is heavier than air.
2. Depress the filler valve at the
back of the tank with a small
bladed screwdriver and let the
butane gas escape through the
small orifice opening. It takes
approximately one minute for
the butane to escape from the
tank. Be careful that the butane
does not hit against your fingers
or hands.This could cause
frostbite of the skin.
3. One method is to poke a small
bladed screwdriver through a
piece of paper and then carefully
depress the filler valve.The
escaping gas will hit the paper
and not your hand.
4. Never turn gas lever to “ON” and
allow gas to evacuate through
the ejector/tip.Doing
this will clog the ejector and
lead to premature failure.
5. Never try to unscrew the filler
valve as it is adhesively bonded
to the tank. Breaking of this
bond will destroy the unit, causing the tank to leak.
