 General Safety Rules  Specific Safety Rules and Symbols  Functional Description  Assembly  Operation  Maintenance  Accessories

ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA REQUIREMENTS or ANSI SAFETY STANDARD Z87.1

FLYING DEBRIS can cause permanent eye damage. Prescription eyeglasses ARE NOT a replacement for proper eye protection.

WARNING: Non-compliant eyewear can cause serious injury if

broken during the operation of a power tool.

SAVE THESE INSTRUCTIONS FOR REFERENCE

WARNING: Use hearing protection, particularly during extended periods of operation of the tool, or if the operation is noisy.

GENERAL SAFETY WARNINGS

CAUTION: Before using this tool or any of its accessories, read this

manual and follow all Safety Rules and Operating Instructions.

Page 4

ELECTRICAL SAFETY

WARNING: To avoid electrical hazards, fire hazards or damage to the

tool, use proper circuit protection.

This tool is wired at the factory for 120 V operation. It must be connected to a 120 V, 15 A circuit that is protected by a time-delayed fuse or circuit breaker. To avoid shock or fire, replace power cord immediately if it is worn, cut or damaged in any way.

GENERAL SAFETY WARNINGS

WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.

WARNING: Dust that is created by power sanding, sawing, grinding,

drilling, and other construction activities may contain chemicals that are known to cause cancer, birth defects, or other genetic abnormalities. These chemicals include:

Lead from lead-based paints Crystalline silica from bricks, cement, and other masonry products Arsenic and chromium from chemically treated lumber

The level of risk from exposure to these chemicals varies, according to how often this type of work is performed. In order to reduce exposure to these chemicals, work in a well-ventilated area, and use approved safety equipment, such as a dust mask that is specifically designed to filter out microscopic particles.

Page 5

GENERAL SAFETY RULES

WARNING: Read and understand

all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.

WORK AREA

Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

Do not operate power tools in potentially explosive environments, such as in the presence of flammable liquids, gas or dust. Power tools create sparks that may ignite dust or fumes.

Keep bystanders, children and visitors away while operating the tool. Distractions can cause the operator to lose control.

ELECTRICAL SAFETY

Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will only fit into a polarized plug one way.

If the plug does not fit into the outlet properly, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not alter the plug in any way. Double insulation eliminates the need for the three-pronged grounded power cord and grounded power supply system.

Avoid contact between the operator's body and grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if the operator's body is grounded.

Do not expose power tools to rain or wet conditions. Water entering the power tool will increase the risk of electric shock.

Do not abuse the cord. Do not use the power cord to carry the tool or to pull the plug out of the outlet. Keep the power cord away from heat, oil, sharp edges, and moving parts. Replace a damaged power cord immediately. A damaged power cord increases the risk of electric shock.

When operating a power tool outdoors, use an outdoor-rated extension cord type “W-A” or “W”. These cords are rated for outdoor use and they reduce the risk of electric shock.

PERSONAL SAFETY

Stay alert, be aware of the surroundings, and use common sense when operating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating a power tool may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewellery.

Contain long hair. Keep hair, clothing, and gloves away from moving parts. Loose clothing, jewellery, or long hair can get caught in moving parts.

POWER TOOL SAFETY

Page 6

PERSONAL SAFETY – cont’d

Avoid accidental start-ups. Verify that the switch is in the OFF position before plugging in the tool. Carrying a power tool with a finger on the switch or plugging in a tool that has the switch in the ON position invites accidents.

Remove adjusting keys and wrenches before turning the tool ON. A wrench or key that is left attached to a rotating part of the tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. Proper footing and balance allows the operator to maintain better control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection.

Use a dust mask, non-skid safety shoes, a hardhat, or hearing protection when appropriate.

USE AND CARE OF POWER TOOLS Use clamps or another practical means to

secure and support the workpiece to a stable platform. Holding the work in a hand or against the body is not stable, and may lead to loss of control.

Do not force the tool. Use the correct tool for the application. The correct tool will do the job better and safer when used at the rate that it was designed to work at.

Do not use a power tool if it cannot be turned ON or OFF using the power switch. A tool that cannot be controlled using the switch is dangerous, and must be repaired.

Disconnect the plug from the outlet before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of accidental start-ups.

When power tools are not in use, store them out of the reach of children or untrained persons. Tools are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind, and are easier to control.

Inspect the tool for misalignment or binding of moving parts, broken parts, and any other condition that may affect the operation of the tool. If it is damaged, have the tool serviced before using it. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the manufacturer for this model. Accessories that are suitable for one tool may become hazardous when used with another tool.

SERVICE Tools servicing must be performed by

qualified personnel. Service or maintenance performed by non-qualified personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow the instructions in the Maintenance section of this Manual. The use of unauthorized parts or failure to follow the instructions in the Maintenance section of this Manual may create a risk of electric shock or injury.

PREPARING SCREW HOLES

It is important to prepare screw holes before attempting to fasten two pieces of wood together. Proper preparation will make screws drive easier and prevent misaligned components, stripped screw heads, splitting and separating of wood components.

1. Clamp the components that are to be screwed together in their desired position (Fig. 9).

2. Drill a pilot hole (1) through the outer piece (2) and into the inner piece (3). Drill the hole 2/3 the diameter of the smooth portion of the screw shank.

NOTE: If the wood is soft, drill the hole 2/3 the length of the screw. If the wood is hard, drill the hole the full length of the screw.

3. Remove the clamp from the two pieces to be screwed together.

4. Enlarge the hole (1) in the outer piece (2) so it is the same size as the smooth portion of the screw shank (Fig. 10).

5. If using a flat head screw, counter-sink the hole (4) so the head of the screw will be flush with the surface when fully driven into place.

DRIVING SCREWS

When driving screws, care must be taken to use a bit that correctly fits the head of the screw being driven. Be sure to use the largest bit size that will properly fit into the head of the screw. The bit must also be in good condition and not worn so it will drive screws without slipping out of the screw head.

Always hold the impact driver with two hands when driving and removing screws to provide the best possible control over the tool.

1. Select the correct screwdriver bit for the screw being driven.

2. Insert the bit into the hex drive (Fig. 6).

3. Set the forward/reverse button to the LEFT for driving screws (Fig. 7).

4. Insert the screwdriver bit (1) fully into the screw head (2) (Fig. 11).

5. While holding the screwdriver firmly against the screw with both hands and the bit aligned with the screw, squeeze the trigger switch and drive the screw.

6. When the screw is driven to the correct depth, release the switch and the impact driver will stop.

ASSEMBLY AND OPERATION

MAINTENANCE

! ! !

Page 25

NICKEL-CADMIUM BATTERY MAINTENANCE

Nickel-cadmium batteries are powerful, rugged and provide hundreds of charge/discharge cycles if properly maintained and periodically ‘exercised’. Exercising is required to recover most of the capacity lost during usage. This process reduces the size of the active cadmium hydroxide crystals on the anode, to expose the entire surface area and restore capacity.

How to care for your Nickel-cadmium battery

1. Never allow a battery to freeze.

2. Do NOT charge a battery when the work area or the battery temperature is at or below 0°C (32° F) or above 45°C (113° F). Allow it to sit at room temperature for at least 30 minutes before charging.

3. Do not charge a battery if it feels warm to the touch.

4. Never charge a battery after a short use. Let it sit until it is needed again.

5. Never charge the battery until the tool in which it is being used cannot produce useful work.

HOW TO EXERCISE A NICKELCADMIUM BATTERY

NOTE: Ni-Cd and Ni-Mh batteries have a

self discharge rate of approximately 1% per day. The self discharge rate depends upon the temperature.

1. Every two months or after 30 charge/discharge cycles, whichever comes first, fully discharge your battery. To fully discharge the battery, place it in the tool that it came with and work with the tool until it nearly stops and no longer produces useful action.

2. If the tool came in a kit with a worklight, insert the battery into the light. Turn the switch ON and leave it ON until the filament is cherry red.

3. Let the battery rest for 30 minutes at room temperature 21° C (70° F) before charging.

4. Charge the fully discharged battery for approximately 1 hour at 21° C (70° F).

LITHIUM-ION BATTERY MAINTENANCE

Lithium-ion batteries share many characteristics with Nickel-Cadmium batteries.

The major characteristic that is NOT shared with Nickel-Cadmium batteries is that Lithium-ion batteries do not have a

“memory” and do not require to be

completely discharged periodically. It is recommended that you charge your Lithium-ion batteries after each use so they will be fully charged when needed.

NOTE: A fully charged battery will loose about 2% of its charge per month during storage.
