electrical safety
1. power tool plugs must match the outlet.
never modify the plug in any way.
Do not use any adapter plugs with grounded
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
2. avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
3. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
4. Do not abuse the cord. never use the cord
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
5. if operating a power tool in a damp location
is unavoidable, use a Ground Fault circuit
interrupter (GFci) protected supply.
Use of a GFCI reduces the risk of electric shock.
personal safety
1. Stay alert, watch what you are doing
and use common sense when operating
a power tool. Do not use a power
tool while you are tired or under the
influence of drugs, alcohol or medication.
A moment of inattention while operating power
tools may result in serious personal injury.
2. use personal protective equipment.
always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes,
hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
3. prevent unintentional starting. ensure the
trigger is in the off-position before connecting
to power source, picking up or carrying the tool.
Carrying power tools with your finger on
the Trigger or energizing power tools that
have the Trigger on invites accidents.
4. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
5. Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing
and gloves away from hot parts.
6. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI-approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work area.
power tool use and care
1. Do not force the power tool. use the
correct power tool for your application.
The correct power tool will do the job better and
safer at the rate for which it was designed.
2. Do not use the power tool if the trigger
does not turn it on and off.
Any power tool that cannot be controlled with the
Trigger is dangerous and must be repaired.
3. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions
to operate the power tool. Power tools are
dangerous in the hands of untrained users.
5. Maintain power tools. check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. if damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
6. use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.

Grounding
tO preVent eLectric SHOcK anD DeatH FrOM incOrrect GrOunDinG
Wire cOnnectiOn:
check with a qualified electrician if you are in doubt as to whether the outlet is properly
grounded. Do not modify the power cord plug provided with the tool. never remove the
grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. if damaged,
have it repaired by a service facility before use. if the plug will not fit the outlet, have a proper outlet
installed by a qualified electrician.
Double insulated tools: tools with two prong plugs
This appliance has a polarized plug (one blade is wider
than the other). To reduce the risk of electric shock,
this plug is intended to fit in a polarized outlet only one
way. If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified
electrician. Do not modify the plug in any way.
Double insulated tools may be used in
either of the 120 volt outlets shown in the
illustration Outlets for 2-Prong Plug.
Outlets for 2-prong plug
extension cords
1. Grounded tools require a three
wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
2. As the distance from the supply outlet increases,
you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss
of power and possible tool damage. (See table a.)
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord. (See table a.)
4. When using more than one extension cord
to make up the total length, make sure
each cord contains at least the minimum
wire size required. (See table a.)
5. If you are using one extension cord for more
than one tool, add the nameplate amperes
and use the sum to determine the required
minimum cord size. (See table a.)
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

tO preVent SeriOuS inJury FrOM acciDentaL OperatiOn:
Make sure that the trigger is in the off-position and unplug the tool from its
electrical outlet before performing any procedure in this section.
note: For additional information regarding the parts listed in the
following pages, refer to Parts List and Diagram on page 10.
1. Using a wrench (sold separately),
check that the Soldering Tip Nuts are
not loose. Do not overtighten.
2. The Soldering Gun comes with three Soldering
Tips for different applications. Select desired
Soldering Tip and install following soldering tip
replacement directions outlined in the Maintenance
and Servicing section on page 8.
Workpiece and Work area Set up
1. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
3. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
5. If wires are to be soldered, thoroughly clean or
scrape the wires so that only the clean metal
is showing, then make the wire splice.
6. If other objects are to be soldered, thoroughly
clean or scrape the metal surfaces. It may
be necessary to apply acid flux (not included)
to the metal surfaces before soldering.
notice: If soldering on printed circuit boards, too
much heat can soften the plastic form and loosen
the metal eyelet connections. Use minimal heat,
or solder with a low wattage soldering pencil.
Never use acid-core solder on wiring circuits.
note: Users who are new to soldering may
find it helpful to practice soldering on scrap
wires and splices prior to actual use.
General Operating instructions
1. Set the Soldering Gun on a fireproof workbench
away from all flammable materials and plug
the Power Cord into an electrical outlet.
2. Press on the Trigger until the
Soldering Tip heats up.
3. Apply a sufficient amount of rosin-core solder
to melt over the entire Soldering Tip. Wipe the
tip with a rag until the tip is clean and shiny.
4. Brush on solder flux, as needed, to the workpiece.
Place the Soldering Tip to the joint, wiring
splice, or metal to be soldered.
5. Apply solder to the wire splice or metal
to be soldered, not the Soldering Tip.
When the splice or metal is hot enough, it
will melt the solder causing it to flow within
the splice or between the metal surfaces.
6. When the solder has flowed over the entire
wire splice or metal surface, remove the
Soldering Tip and release the Trigger.
7. To prevent accidents, turn off the tool and
unplug it after use. Clean, then store the
tool indoors out of children’s reach.
