GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future reference.
The term “power tool’’ in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
1. WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
b. 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 dust or fumes.
c. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2. ELECTRICAL SAFETY
a. 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.
b. 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.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d. 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.
e. 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.
f. If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD
reduces the risk of electric shock.
3. PERSONAL SAFETY
a. 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.
b. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
c. 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. Carrying power tools with
your finger on the switch or energising power tools
that have the switch on invites accidents.
d. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
e. Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g. 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.
4. POWER TOOL USE AND CARE
a. 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.
b. 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.
c. 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.
d. 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.

2
English
e. 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and
in the manner intended for the particular type
of power tool, taking into account the working
conditions and the work to be performed. Use
of the power tool for operations different from
intended could result in a hazardous situation.
5. BATTERY TOOL USE AND CARE
a. 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.
b. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or fire.
d. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
6. SERVICE
a. Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
b. The product is not intended for use by young
children or infirm persons unless they have been
adequately supervised by a responsible person to
ensure that they do not play with the product.
c. Keep children and visitors away. Visitors
should wear safety glasses and be kept at a safe
distance from the work area. Do not let visitors
contact tool or extension cord.
d. Complies with AS/NZS 60335.

BATTERY PROTECTION FEATURES
Ryobi 18 V lithium-ion batteries are designed with
features that protect the lithium-ion cells and maximize
battery life. Under some operating conditions, these
built-in features may cause the battery and the tool it is
powering to act differently from nickel-cadmium batteries.
During some applications, the battery electronics may
signal the battery to shut down, and cause the tool to
stop running. To reset the battery and tool, release the
trigger and resume normal operation.
NOTE: To prevent further shut down of the battery, avoid
forcing the tool.
If releasing the trigger does not reset the battery and
tool, the battery pack is depleted. If depleted, the battery
pack will begin charging when placed on the lithium-ion
charger.
TO INSTALL BATTERY PACK (NOT INCLUDED)
See Figure 2.
■Lock the switch trigger by sliding the switch lock up.
■Place the battery pack on the tool.
■Make sure the latches on each side of the battery
pack snap into place and the battery pack is secured
on the tool before beginning operation.
TO REMOVE BATTERY PACK (NOT INCLUDED)
See Figure 2.
■Lock the switch trigger by sliding the switch lock up.
■Depress the latches on the side of battery pack.
■Remove the battery pack from the tool.
STARTING/STOPPING THE CAULK GUN
See Figure 3.
Before attempting to start the caulk gun, be sure the
switch lock is in the unlocked position.
■To turn the caulk gun ON, depress the switch trigger.
■To turn the caulk gun OFF, release the switch trigger.
LOCKING THE SWITCH TRIGGER
See Figure 3.
The switch trigger of the caulk gun can be locked off
using the slide switch located below the switch trigger.
■To lock the switch trigger, slide the switch lock up.
This will prevent the caulk gun switch trigger from
being depressed.
■To unlock the switch trigger, slide the switch down.
This will allow the caulk gun switch trigger to be
depressed.
LOADING CAULK (NOT INCLUDED)
See Figure 4-5.
■Lock the switch trigger by sliding the switch lock up.
■Using a utility knife, cut off the tip of the spout on a
standard 310 ml (10 oz.) tube of caulk. Cut the tip at
an angle of 45°.
■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

4
English
any hardened material from the tip.
NOTE: An inner seal is usually found only in
cardboard caulk tubes.
■While holding the caulk gun steadily with one hand,
pull the handle of the plunger rod away from the caulk
gun. Continue pulling until the plunger base reaches
the back of the carriage frame.
■Load the caulk tube into the carriage frame, making
sure it is well seated at both ends.
ELECTRONIC OVERLOAD PROTECTION
The caulk gun is protected by an electronic overload
protection 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:
■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
■Plunger rod is free of caulk/adhesive materials
Release the trigger and wait for 3 to 5 seconds to allow
the electronics to reset. If the motor again shuts off, move
the variable speed selector to the middle position and
press the trigger again. If the motor continues to shut
off, try another tube of material or take the tool to an
authorized service center.
WARNING
Battery tools are always in operating condition.
Therefore, switch should always be locked when
not in use or when carrying at your side.
HOW TO GET STARTED - APPLYING CAULK
See Figure 6-8.
■Experiment in an out-of-the-way area to find the
best speed to use to deliver the caulk bead you want.
■Prepare the surface to be caulked by removing any
dust, dirt, or remnants of old caulking. Make sure the
area to be caulked is clean and dry.
■Set the speed of the caulk gun to match your
application needs, using just enough caulk to do the
job.
■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, allowing the
caulk to extrude from the tube tip.
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.
■Carefully move the caulk gun at an even pace along
the gap to be filled as you continue to depress the
switch trigger. Make sure the caulk comes in full
contact with both application surfaces. If necessary,
use your finger to gently press the caulk into a corner
or crack.
NOTE: The best fill is usually achieved by pushing
the caulk out into the gap in a forward motion.
However, in some cases (particularly where the side
materials are rough or uneven), a pulling motion may
work better as the cartridge will be less likely to get
snagged along the joint.
■The motor will shut off automatically when a caulk
tube becomes empty. Pull the plunger rod back and
replace the caulk tube as necessary.
■To end the caulk bead, release the switch trigger.
■Draw a moistened finger or other “smoothing tool”
along the caulk bead after applying. This will help
the caulk adhere to the application surfaces and will
create a clean, finished appearance.
■Use a damp towel or rag to clean off any excess
caulk.
