tions will reduce personal injuries.
WARNING!
Read all instructions. Failure to follow all instruc-
tions listed below may result in electric shock, fire
and/or serious injury. The term “power tool” in all
of the warnings listed below refers to your mains-
operated (corded) power tool or battery-operated
(cordless) power tool.
Avoid accidental starting. Ensure the switch is in the off-
position before plugging in. Carrying power tools with your
finger on the switch or plugging in power tools that have the
switch on invites accidents.

power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be caught in
moving parts.
Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
If devices are provided for the connection of dust extrac-
tion and collection facilities, ensure these are connected
and properly used. Use of these devices can reduce dust-
related hazards.
Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
Do not wear loose clothing or jewelry. Contain long hair.
Loose clothes, jewelry, or long hair can be drawn into air
vents.
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. Unmodified plugs and
matching outlets will reduce risk of electric shock.
Do not use on a ladder or unstable support. Stable footing
on a solid surface enables better control of the power tool
in unexpected situations.
Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is earthed
or grounded.
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 not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
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.
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.
When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suitable
for outdoor use reduces the risk of electric shock.
Use battery only with charger listed.
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.

OPERATION
THE FOLLOWING INSTRUCTIONS ARE
FOR RIDGID 24V LITHIUM-ION BATTERY
PACKS AND THE 24V RIDGID LITHIUM-ION
CHARGER.
WARNING:
Do not allow familiarity with tools to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
CHARGING THE BATTERY PACK
NOTE: New 24 Volt lithium-ion battery packs will not
work without first being charged. Before first time use,
charge the battery pack to activate it.
WARNING:
Always wear safety goggles or safety glasses with
side shields when operating tools. Failure to do so
could result in objects being thrown into your eyes
resulting in possible serious injury.
It is not necessary to drain the battery pack completely
before recharging. Lithium-ion battery packs have no
“memory” and can be recharged at any time. It is therefore
possible to charge the battery pack before extended usage
even if the battery pack is not completely drained of charge.
Use the charge level indicator to determine the amount of
charge in the battery pack.
WARNING:
Do not use any attachments or accessories not
recommended by the manufacturer of this tool.
The use of attachments or accessories not rec-
ommended can result in serious personal injury.
Lithium-ion batteries deliver fade free power for their entire
run time. 24 Volt lithium-ion tools will not gradually lose
power due to decreasing battery charge. Instead, power from
the battery pack will drop from full to zero once the full charge
has been drained from the battery. Once this happens, the
tool’s power drops from full to zero, and recharging of the
battery is required.
APPLICATIONS
You may use this tool for the purposes listed below:

OPERATION
ADJUSTING THE VARIABLE SPEED
See Figure 8.
The trigger pressure, speed selection, material type, tem-
perature, and nozzle diameter will all affect the material flow
rate. When using a tube or pack with a smaller diameter
nozzle, use a slower speed rate or the material could be
forced around the seal at the rear of the tube.
LOW SPEED
Use the variable speed selector knob to set the maximum
speed rate desired for proper bead width and material
feed rate.
VARIABLE SPEED
SELECTOR
Change the amount of pressure applied to the switch
trigger to increase or decrease the speed of material
delivery up to the maximum speed set by the variable
speed selector.

LOADING CAULK
See Figures 9 - 10.
SPOUT
Lock the switch trigger by sliding switch lock up.
Using a utility knife, cut off the tip of the spout on a tube
of caulk. Cut the tip at a 45˚ angle. Remove as little as
possible, taking into consideration the size of the “bead”
of caulk you need.
Check for a second inner seal at the base of the spout. If
found, insert the puncture tool inside the spout to break
the seal before using. If using a partially filled tube, use
the puncture tool to remove any hardened material from
the tip.

The caulk gun is protected by an electronic overload protec-
tion feature. If too much pressure is exerted on the tube,
the motor will shut down. This helps to prevent damage
to the tool and the caulk tube. If the motor shuts off, make
sure that:

ADHESIVE BEAD
APPLYING ADHESIVE WITH THE JOIST
FOLLOWER
See Figure 12.
Use the joist follower to put a straight center bead of adhesive
on wood surfaces between 1-1/4 in. and 2-5/8 in. wide.
Install the joist follower as previously described.
Prepare the surface by removing any dust, dirt, or remnants
of old adhesive. Make sure the area is clean and dry.
JOIST
FOLLOWER
Set the speed of the caulk gun to match your application
needs, using just enough adhesive to do the job. Experi-
ment in an out-of-the-way area to find the best speed
and trigger pressure to use to deliver the adhesive bead
size you want.
Hold the gun at a slight angle.
Squeeze the trigger on the caulk gun, allowing the adhe-
sive to extrude from the tube tip.
Fig. 12
NOTE: If the bead of adhesive is too narrow, re-cut the
nozzle to provide a larger opening.
Carefully move the caulk gun at an even pace along the
surface.
The motor will shut off automatically when an adhesive
tube becomes empty. Depress the plunger rod release
trigger, pull the plunger rod back, and replace the tube
as necessary.
To end the adhesive bead, release the switch trigger.

OPERATION
APPLYING CAULK
See Figure 13.
CAULK BEAD
Prepare the surface by removing any dust, dirt, or remnants
of old caulk. Make sure the area is clean and dry.
Set the speed of the caulk gun to match your application
needs. Experiment in an out-of-the-way area to find the
best speed and trigger pressure to use to deliver the caulk
bead size you want.
Hold the gun at a slight angle. If filling a crack, insert the
spout into the crack, if possible; otherwise, run the caulk
gun along the surface.
Squeeze the trigger on the caulk gun and move the caulk
gun at an even pace along the surface.
NOTE: If the bead of caulk is too narrow, re-cut the nozzle
to provide a larger opening. However, it is better to apply
a thin bead of caulk and add a little more if necessary than
to apply too much and attempt to remove the excess.
To end the caulk bead, release the switch trigger.
For a finished appearance and to help the caulk adhere
to application surfaces, draw a moistened finger or other
“smoothing tool” along the caulk bead after applying.
Use a damp towel or rag to clean off any excess caulk.
