PERSONAL SAFETY
GENERAL POWER TOOL SAFETY WARNINGS
WORK AREA SAFETY
ELECTRICAL SAFETY
•Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
•Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids,gasesor dust. Power toolscreatesparks
which may ignite the dust or fumes.
•Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
•Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodifiedplugs and matching outlets will
reduce risk of electric shock.
•Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.Thereis an increased riskofelectric
shock if your body is earthed or grounded.
•Do notexposepower tools to rain orwet condi-
tions. Water entering a power tool will increase
the risk of electric shock.
•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.
•When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk
of electric shock.
•If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Useof an RCD reduces
the risk of electric shock.
•Remove any adjusting key or wrench before
turning the power tool on. Awrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
•Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
•Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
•If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
•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.
•Do notuse the power tool ifthe switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
•Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
•Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Powertoolsaredangerousin the
hands of untrained users.
•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. Manyaccidents
are caused by poorly maintained power tools.
•Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
•Use the power tool, accessories and tool bits
etc., in accordance with these instructions,
takinginto account the working conditionsand
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
•Stay alert, watch what you are doing and use
common sensewhen operatinga power tool.Do
not use apower tool while you aretired or under
theinfluenceof drugs, alcohol ormedication. A
moment of inattention while operating power tools
may result in serious personal injury.
•Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearingprotectionusedforappropriateconditions
will reduce personal injuries.
•Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carryingpowertoolswith
yourfingeronthe switch or energising power tools
that have the switch on invites accidents.
•Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.

accessories. Only use accessories specifi-
cally recommended for this tool. Others may
be hazardous.
4. Pull the rod handle back to allow the tube to fit
inside the carriage. As the tube is inserted, the
lever will slide back and apply pressure to hold
the tube in place.
Using the Control Switch
The control switch may be set to
two positions: forward and lock.
For forward, push in the control
switch from the right side of the
tool. The tool will run normally.
To lock the trigger, push in the
control switch from the left side of
the tool. The trigger will not work
while the control switch is in the
locked position. Always lock the
triggerorremovethebatterypack
before performing maintenance,
changing accessories, storing
the tool and any time the tool is
not in use.
Anti-Drip and Rod Release
The caulk gun features an automatic anti-drip to
preventdripsafterthe trigger is released. When the
triggerisreleased, the motor will runforashorttime
to release the cluch, but the rod will not move (un-
less pressure in the tube pushes the piston back).
End of travel
When a tube is emptied, the motor will run for a
short time to release the cluch, then shut off. Re-
lease the trigger and change the tube.
Overload
When an overload occurs, the tool will reach the
maximum drive force and continue to hold this
maximum force until the user releases the trigger.
If material is not dispensing, make sure that:
• Nozzle tip is cut
• Inner seal in the caulk tube is broken
• Hardened material is removed from the nozzle
• Caulk tube is not damaged or frozen
• Rod is free of caulk/adhesive materials
Starting and Stopping and Controlling Speed
1. Pull trigger to dispense material.
2. Increase or decrease pressure on the trigger to
dispense the material. Adjust the speed dial to
selectthemaximum speed for proper bead width
and material flow rate ("1" for slowest, "6" for
fastest). The trigger pressure, selected speed,
material type, temperature and nozzle diameter
will all affect the flow rate. When using a tube or
packwitha smaller nozzle diameter useaslower
speed or the material may be forced around the
rear tube seat.
NOTE: Operating the gun at high speeds may
damage the dispensing tube or pack for some
materials. For best results, gradually increase
speed settings.
3. Releasetriggertostopdispensing material.The
rodis free to bemovedmanuallywhen the trigger

NOTE: Keep the piston and rod clean. Retracting
or inserting a piston that is covered with material
may damage the internal parts of the tool.
Installing the Carriage or Barrel
Placethecarriageover the piston and rod. Hold the
carriagecollarsecurelywhile screwing the carriage
into the collar.
WARNINGTo reduce the risk of injury,
keep hands out of the piston area
of the tool. Fingers can be pinched between
carriage and the piston.
Installing Caulk or Adhesive Tube
Always check tubes for punctures or damage
before installing. Do not use a damaged or frozen
tube.
1. Remove battery pack.
2. Cut nozzle of tube at an angle and size per
manufacturer's recommendation to suit the job
(unless the nozzle is pre-cut). A smaller nozzle
diameter requires more force to push the caulk
and reduces battery life.
3. Break the inner seal of the tube. If the inner seal
is not broken, the caulk material may be forced
out the rear end of the tube and damage the
tool.
NOTE: Before using a partially filled tube, re-
move any hardened material with a long nail or
piece of wire.
5. Insert tube into the carriage.
6. Push the rod handle forward until the piston is
against the tube.
7. To remove the tube, pull the rod handle back.
