Master Appliance UT-40Si How to Empty Tank of Butane Gas if Needed, Trouble Shooting

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

4

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.

	gas pressure	higher or lower position.
Tip does not heat up	a. Used-up catalyst	a. Replace with new tip
	b. Insufficient gas pressure	b. Refill with butane gas
	c. Ejector is clogged	c. Replace with new ejector

Important Safety Instructions

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.
