Trouble Shooting
Problem
Does not ignite
Tip does not heat up
Probable cause
a. Empty tank
b. Clogged ejector
c. Too high or too low
gas pressure
a. Used-up catalyst
b. Insufficient gas pressure
c. Ejector is clogged
Solution
a. Refill with butane fuel
b. Replace with new ejector
c. Slide control lever to a
higher or lower position.
a. Replace with new tip
b. Refill with butane gas
c. Replace with new ejector
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.
Important Safety Instructions
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 carriage 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 alcohol-based 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.
