General Power Tool Safety Warnings

WARNING

G! Read all safety warnings and 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 the 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.
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 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.

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 a 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.

Additional safety instructions for Adhesive Guns

• Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the tool "live" and shock the operator.
• Keep hands out of the plunger and plunger rod area of the adhesive gun. Fingers can be crushed between the tube holder and the plunger.
• When operating the adhesive gun overhead, do not have the plunger rod in the path of your eyes or head. The plunger rod may slip back in direction of user. Always wear eye protection when using the adhesive gun.
  • Always work in properly ventilated area and wear appropriate respiratory protection if necessary. Fumes from some caulks and adhesives can be noxious.

ENGLISH

• Turn unit off and disconnect battery pack before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.
• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may be hazardous when used on another tool. The use of improper accessories may cause risk of injury to persons.
• Lock trigger in the OFF position when not in use to avoid inadvertent release of material.
  • Take care not to get caulk or adhesive on battery contact points.
• Always read and follow all manufacturer's instructions regarding caulk or adhesive. Failure to do so may result in personal injury.

DANGER: Keep hands out of the plunger and plunger rod area.

WARNING: Do not use the tool on a ladder.

Residual Risks

In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are:

– Risk of pinching or crushing fingers.

1. Remove the plunger screw (r) and cartridge plunger (s) from inside of cartridge holder (j).
2. Press and hold the plunge rod release trigger (a) and pull plunger rod handle (f) back to access the barrel nut (t). Release plunger rod release trigger.

3. With a 13 mm (1/2") square drive tool, turn the barrel nut (t) anticlockwise to remove.

4. The rear end washer (x), spacer (u) and cartridge holder (j) are now easily removed.

TO INSTALL SAUSAGE HOLDER (FIG. 4)

1. Position the rear cap spacer (v) and the rear end cap (w) [fine threads] onto nose of the tool.
   NoTE: The side of the rear cap spacer with the double collar faces away from the tool.
2. Place the rear end washer (x) on top of the rear end cap (w) and thread barrel nut (t) into the nose of the tool. Tighten and secure the barrel nut with a 13 mm (1/2") square drive tool. This caulk gun is designed to allow the rear end cap to rotate freely.
3. Press and hold the plunger rod release trigger and push the plunger rod (g) completely forward. Release the trigger.
4. Thread the sausage holder (l) onto the rear end cap (w).
5. Assemble the barrel plunger (y) onto the plunger rod (g) and thread the plunger screw (aa) into the plunger rod in the order shown in Figure 4. This will secure the barrel plunger (y) in place. Tighten securely.

NoTE: Prior to assembly of the sausage holder (I), ensure the o-ring (z) has been fully lubricated. If not, use the lubricant included to completely lubricate the o-ring prior to assembly. Periodic lubrication of the plunger o-ring (z) may be needed during the life of the caulk gun. To maintain smooth operation while dispensing material, apply a light coating of the proviced lubricant to the outside surface of the o-ring.

ImPoRTaNT:

• Under normal use, the lubricant included with the caulk gun is not expected to cause eye irritation. Eye irritation may occur under direct contact or in poorly ventilated areas.
• Short term skin contact with the lubricant is not expected to cause irritation. Direct, repeated or prolonged exposure may result in skin irritation and redness.
• Press and hold the plunge rod release trigger and pull the plunger rod handle back before loading material. Pulling the barrel plunger back will lubricate the inside of the sausage holder (I). Initial resistance of the plunger rod is expected until the barrel plunger has been pulled completely back.
• Place the nozzle (n) onto the sausage holder (l) and thread the nozzle cap (m) over the nozzle.

To remove the sausage holder, reverse the above procedure.

NOTE: The barrel nut (t) may occasionally need to be retighten to ensure the tool functions properly. If the barrel nut in the carrier becomes loose, use a 13 mm (1/2") square drive tool to retighten.
