GENERAL POWER TOOL SAFETY WARNINGS

WARNING!
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 mainsoperated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

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.
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.
Do not expose power tools to rain or wet conditions. 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 ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
Use this product only with batteries and chargers listed in tool/appliance/battery pack/charger correlation supplement 987000-432.

PERSONAL SAFETY

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.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions 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. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
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.
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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry 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.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents.
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.

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 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.
Disconnect the plug from the power source and/ or remove the battery pack, if detachable, 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 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.
Maintain power tools and accessories. 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.
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, 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.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

BATTERY TOOL USE AND CARE

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.
Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
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 a fire.
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.
Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F may cause explosion.
Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

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.
Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

For complete charging instructions, see the operator’s manuals for your battery pack and charger.
LOCKING THE SWITCH TRIGGER
See Figure 2, page 9.
The switch trigger can be locked off using the slide switch located below the switch trigger.

To lock the switch trigger, slide the switch lock to the left.
This will prevent the switch trigger from being depressed.
To unlock the switch trigger, slide the switch to the right.
This will allow the switch trigger to be depressed.

STARTING/STOPPING THE CAULK GUN
See Figure 2, page 9.
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.

WARNING:
Battery tools are always in operating condition. Lock the switch when not in use or carrying at your side, when installing or removing the battery pack, and when loading or removing caulk tubes.
VARIABLE SPEED DIAL
See Figure 3, page 9.
The variable speed dial, located on the top of the tool, allows the caulk gun to operate at different maximum speeds. The maximum speed can be adjusted before or during operation. To change the maximum speed during operation, hold the caulk gun in a normal operating position, fully depress the switch trigger, and rotate the dial clockwise or counterclockwise. To change the maximum speed prior to operation, rotate the dial clockwise or counterclockwise.
LOADING CAULK
See Figures 4 – 5, page 9.

Lock the switch trigger by sliding the switch lock to the left.
Using a utility knife, cut off the tip of the spout on a standard 10 oz. 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.
NOTE: An inner seal is usually found only in cardboard caulk tubes.
While holding the caulk gun steady with one hand, pull the handle of the plunger rod away from the caulk gun. Continue pulling until plunger base reaches the back of the carriage frame.
NOTE: Removing the plunger rod from the caulk gun is not recommended. Improper reinstallation can lead to decreased performance until reassembled correctly.
Insert the flat end of the caulk tube into the carriage frame then lower the nozzle. Make sure the tube is well seated at both ends.

To remove:

Lock the switch trigger.
While holding the caulk gun steady with one hand, pull the handle of the plunger rod away from the caulk gun. Continue pulling until plunger base reaches the back of the carriage frame.
Lift the tube up and away from the caulk gun.

ELECTRONIC OVERLOAD PROTECTION
The caulk gun has 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.
APPLYING CAULK
See Figures 6 – 7, page 10.

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.
Unlock the switch trigger.
Set the speed of the caulk gun to match your application needs, using just enough caulk to do the job. Experiment in an out-of-the-way area to find the best speed to use to deliver the caulk bead 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 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.
