1. INTRODUCTION
COBRA Static Neutralizing Blow-off Guns are lightweight, ergonomic com-
pressed air guns designed for cleaning large surfaces. The COBRA Gun uses
airflow amplification in conjunction with ionization to produce an air blast that
neutralizes static electricity and cleans at the same time. Included with the gun is
a convenient hook for storing the COBRA Static Neutralizing Blow-off Gun and
an accessory nozzle that produces a fan-shaped air blast.
Simco-Ion’s G165 (120 Volt) and G255 (230 Volt) power supplies are designed as
power sources for the COBRA Static Neutralizing Blow-off Guns. Each power
unit can energize one or two guns and features an on/off switch with a power
indicator light.

4. INSTALLATION
Power Supply Mounting:
1. Mount the power supply to a secure flat surface such as a wall, bench or ma-
chine frame (preferably away from operator contact). Secure with screws or
bolts using the mounting flanges at the base of the unit.
Electrical Connections:
1. Ensure that the power supply is deenergized.
2. Center a plastic strain relief over the short length of clear tubing near the con-
nector end of the gun cable. Locate the strain relief over the mounting holes on
the power supply’s lid and secure with the two screws provided.
3. Guide spring loaded cable connectors, on the end of the gun cable, into the out-
put terminals of the power supply and tighten.
NOTE - FINGER TIGHTEN ONLY.
Both connectors must use terminals on the same
side of the power unit (see illustration below).
4. The power supply is grounded when plugged into a
3-prong electrical outlet. If a grounded outlet is not
available, connect a heavy copper wire from the ground
terminal of the power supply to a well-grounded electri-
cal conduit or water pipe. The 230-volt power supply will require installation
of an appropriate plug onto the end of the line cord. The 230-volt connections
are: Black-Line; White-Line; Green-Ground.
Compressed Air Connections:
1. Connect a 3/8” ID flexible airline to the base of the gun handle. If a quick con-
nect coupler is used, a ¼” internal orifice or larger is recommended to supply
adequate air to the COBRA gun. Performance will be reduced if connectors
with inadequate orifice size are used.
2. The airline should be run adjacent to the gun’s electrical cable and linked to-
gether at 12” intervals to provide easier handling of the gun unit.
3. Connect the flexible airline to a source of compressed air of no greater than 100
psi. The source should be filtered to remove dirt, oils, and moisture.

Hook Installation:
A mounting hook is included for hanging the COBRA gun against a wood or sheet
metal surface when not in use. Locate the hook at the desired mounting level and
mark hole locations. Drill 1/8” pilot holes and secure the hook with the screws
and spacers provided. Note that spacers should be placed between the hook and
the mounting surface before installing screws.
5. OPERATION
Before energizing any power supply:
1. Ensure that all power supplies are properly grounded.
2. Ensure that all static control devices are properly grounded.
3. Ensure that all static control devices have been properly located, positioned
and installed.
After the above checks have been performed, simply energize each power supply
to operate the static control device.
For optimal performance, first blow off the target surface with the gun held as
close to the surface as required to remove dirt and dusts. Then, use a broad sweep-
ing motion with the gun 12” to 24” from the surface. Be sure that the ionized air
stream from the gun contacts all areas of the target surface to ensure thorough
static neutralization.
The COBRA gun is supplied with an accessory nozzle that produces a fan-shaped
ionized air blast. The accessory nozzle may be used to increase the area covered
for cleaning purposes.
Switch the power supply unit off during prolonged periods of non-use such as
plant shutdowns and overnight. This will ensure a long ionizer life with optimum
ion output.
CAUTION – Personal Protective Devices Recommended – Always wear
safety glasses or goggles when operating blow-off gun. The purchaser is
responsible for providing effective chip guarding to protect personnel in
the area from blown debris. Also, wear hearing protection if the blow-off
gun is operated more than 1½ hours per day.

6. TROUBLESHOOTING
NOTE – Only qualified service personnel are to perform troubleshooting
tasks.
Operational Check:
1. Rub a small strip of plastic film until a static charge is developed (cellophane
works well). The charge will be evident by the film’s attraction to your hand.
2. Pass the film in front of the gun while depressing the trigger. Hold the film to
see if it is still attracted to your hand.
3. If the film is no longer attracted to your hand, the static charge has been neutral-
ized and the gun is working properly.
Cable Retermination:
If the cable becomes damaged, it can be shortened to remove the damage and
reterminated.
CAUTION – Electrical Shock Hazard – Always disconnect power supply
before connecting or disconnecting static neutralizing equipment. Avoid
touching static neutralizing point when power supply is energized.
1. Disconnect and remove damaged cable from the power supply.
2. Cut off damaged cable, remove 2” clear tubing and slide approximately 10”
onto gun cable.
3. Strip 4½ ” from the black outer jacket.
NOTE – Use extreme caution not to damage or nick the white wire
insulation.
4. Strip the white wire insulation 1” and bend the conductor to form a double
thickness ½” long.
5. Remove the spring loaded cable connectors (SLCC) from the damaged cable
and install them onto the prepared cable.
6. Secure the cable to the power supply using a strain relief fitting and install the
SLCC’s into the power supply’s output terminals.

If equipment fails to function properly:
1. Deenergize the power supply.
2. Ensure all ground connections are intact.
3. Check that all cable connections are tight.
NOTE – FINGER TIGHTEN ONLY.
4. Energize the power supply (if equipped with an ON/OFF switch,
ensure that it is in the ON position).
5. Use a static bar checker (Simco-Ion # 4000004) to verify the presence of high
voltage at the ionization point. If the point is not working, check the area for
metallic fragments or other contamination.
6. If no contamination is found, either the gun or the power supply is defective.
To identify which is not working:
• Deenergize the power supply.
• Disconnect all static control devices from the power supply by unscrewing
the knurled plugs and gently pulling out each high voltage cable.
• Connect an insulated test wire to the power supply’s ground stud.
• Energize the power supply.
• Slowly insert the free end of the test wire into one of the high voltage recep-
tacles. As the insulated wire approaches the contact within the terminal, a
spark should occur and arcing should be heard. If a spark occurs and arcing
is heard, then the gun is faulty. Otherwise, the power supply is faulty. If
either is faulty, contact Simco-Ion Customer Service or your local Simco-Ion
Representative.

7. MAINTENANCE
NOTE – Only qualified service personnel are to perform maintenance
tasks.
NOTE – Never use hard or sharp objects to scrape ionization points.
CAUTION – Electrical Shock Hazard – Deenergize all power supplies before
performing any maintenance tasks.
CAUTION – Fire Hazard – Never energize a power supply with any trace of
alcohol remaining on the equipment.
Dust or dirt around the ionization point will reduce the effectiveness of the static
bar. The ionization points must be cleaned periodically to prevent deposits from
accumulating:
1. Deenergize all power supplies before performing any maintenance tasks.
2. Allow a gentle flow (5-10 psig) of compressed air through the gun during
maintenance.
3. Use dry compressed air to remove loose particulate from the gun. A soft
brush with plastic bristles may be used as well.
4. Press a soft pencil eraser onto the ionization point and gently twist to remove
any buildup.
5. Wipe ionization point with isopropyl alcohol applied to a clean dry cloth to
remove ink or resistant coatings.
NOTE – The alcohol must not contain additives.
NOTE – Do not pour alcohol directly onto the gun, and do not soak the
gun or any of its components in alcohol.
CAUTION – Fire Hazard – Ensure all traces of alcohol have been removed
and the gun is completely dry before energizing the power supply.
