Safety

Read and understand all safety warnings before using the tool.

• Avoid dangerous environments. 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.

• Do not use this product if it is not completely assembled or if any parts appear to be missing or

damaged. Use of a product that is not properly and completely assembled could result in serious

personal injury.

• Inspect the tool carefully to make sure no breakage or damaged occurred during shipping.

• If any parts are damaged or missing do not operate this tool until the missing parts are replaced. Use of

this product with damaged or missing parts could result in serious personal injury.

• Do not attempt to modify this tool or create accessories not recommended for use with this tool. Any

alteration or modification is misuse that will void product warranty and could result in a hazardous

condition leading to possible serious personal injury.

• To prevent accidental starting that could cause injury, always remove the battery pack from the tool

when assembling parts.

• Keep the tool and all components away from children.

• Keep children and bystanders away while operating power tools.

• Keep the work area clean and well lit

• Keep the tool pointed away from yourself and others at all times. Keep hands and body parts away from

moving parts and use safety guards.

• Do not allow persons unfamiliar with the tool or its operation to use the tool.

• Use safety equipment. Always wear eye and ear protection. Safety equipment such as dust mask, non-

skid safety shoes and hard hat should be used in appropriate conditions.

• Only use parts and accessories recommended by manufacturer.

• Do not modify any part of the tool or its safety mechanisms.

• Do not use in ambient temperatures above 40°C (104°F).

• Do not use the tool outside of its operating parameters. For example, polishing.

• Cutting discs may become hot during use – wear suitable protective gloves when handling discs.

• Always use the correct type of grinding / cutting disc for the material and the rotational speed (7000RPM)

of the tool –discs designed for slower operating speeds may become over-stressed and fracture or break

apart if used at higher than rated speeds.

• Do not grind using cut-off discs, or cut using grinding discs. Always use the correct type and size (that is,

outside diameter and bore diameter) of disc for the type of work to be performed. Do not use toothed

saw blades etc or discs that are not designed for a tool of this type.

• Do not start the tool with the disc inside a cut or against any object. Always allow the disc to be running

at full speed before contacting it to the work-piece.

• Position yourself to not be in the path of sparks or debris created by the tool. Always be aware of the

direction in which sparks / debris may be ejected from the tool.

• Kick-back – "Kick-back" is a sudden reaction to a pinched, bound or misaligned cutting disc. If the

rotating disc becomes pinched or digs into in the work-piece, the disc may stall and the motor reaction

can drive the tool rapidly back toward the operator – this is highly dangerous. To help avoid kick-back:

• Always maintain a firm grip with both hands on the tool and position your arms to resist kick-back

forces.

• If the disc is binding, or when stopping a cut before completing it for any reason, release the trigger

and hold the tool motionless in the blade comes to a complete stop. Never attempt to remove the

cutting disc from the work-piece or pull the tool backward while the disc is in motion. If binding

occurs, investigate and take corrective actions to eliminate the cause of binding.

• When restarting the tool with the disc in the work-piece, centre the disc in the cut and check that it is

not engaging the material.

• Support large work-pieces to minimize the risk of pinching and kick-back. Supports must be placed

under the work-piece on both sides of the cut, near the line of cut and near the edge of the work-

piece.

• Do not use excessively worn or damaged cutting / grinding discs.

• Use extra caution when making “plunge cuts”.

• Keep hands away from the cutting area and disc – always use both hands to hold the tool when cutting.

• Never hold the work-piece being cut in your hands or across your legs, body etc. Always secure the

work-piece to a stable platform. It is important to support the work-piece properly to minimize body

exposure, disc binding, or loss of control.

• Hold the tool by the insulated handles only when cutting to help reduce the possibility of electrical shock

should the tool make contact with "live" wires.

• Always use cutting discs of the correct size and arbour size. Discs that do not match the mounting

hardware will run eccentrically, causing loss of control.

• Never use a damaged or non-original disc collar. Use of substitutes may present a safety hazard.

• Check that the disc guard is secure before each use. Do not operate the tool if the disc guard is loose or

not installed.

• Do not use on magnesium.

• Use extra caution when using the tool on sharp corners or edges and avoid bouncing the disc, chatter,

vibration and kick-back.

• Always observe that the cutting disc has stopped rotating completely before placing the tool down.

Battery and Charging Safety

• Use only with the batteries and battery charger specified by the manufacturer.

• Do not open the battery – danger of short-circuiting.

• Do not attempt to destroy or disassemble battery pack or remove any of its components.

• Do not touch the battery terminals with metal objects and/or body parts as short-circuit and/or personal

injury may result.

• Explosion hazard – protect the battery against heat; for example, direct sunlight and fire.

• Explosion hazard – do not short-circuit the battery.

20V Cordless Angle Grinder AG2

• Poison hazard – battery leakage (liquid ejection) may cause irritation or burns. Under extreme

conditions, liquid may be ejected from the battery – avoid contact. If contact occurs, flush with water. If

eye contact occurs, flush with clean water for at least 10 minutes and seek medical attention.

• Care when charging. Make sure cord for the battery charger is located so that it will not be stepped on,

tripped over, or otherwise subjected to damage or stress. Do not operate the battery charger if it has a

damaged cord or plug.

• Dispose of non-serviceable batteries in an environmentally responsible manner.

Servicing

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This

will ensure that safety of the tool is maintained.

Intended Use

• Cutting / grinding suitable materials (metal etc).

Batteries and Battery Charging

Batteries for this tool are supplied in a low-charge condition for shipping reasons. • A battery that is

new or has not been used for a long period does not charge to full capacity until after approximately

5 charge/discharge cycles. • Do not recharge batteries after using them if they are not to be used for an

extended period of time. • Recharge batteries only as and when required. • If the battery is warm after use,

allow it to cool before charging, otherwise it may not fully charge.

The battery packs can be recharged again and again. However, rechargeable batteries eventually need to

be replaced. A significantly reduced working period after charging indicates that the battery is no longer

serviceable and should be replaced. Discard old batteries in an environmentally responsible manner.

Charging

The battery charger has a charge status LED indicator:

• Red - Battery charging.

• Green - Battery fully charged.

1. Plug the battery charger power supply into a 240VAC mains

electrical outlet and switch the supply ON.

2. Slide the battery fully into the battery charger. The indicator LED on the battery charger will be red to

show the battery is charging. The indicator will become green when the battery is fully charged

(approximately 1 to 1.5 hours).

3. When the battery is fully charged, unplug the charger from power supply, then press and hold the

battery release button and simultaneously slide the battery pack from the charger.

Inserting and Removing the Battery Pack

Insert the battery pack into the tool handle until it "clicks" into place.

To remove the battery pack, press and hold the battery release

button (A) and simultaneously pull the battery from the tool.

Assembly

1. Install the handle (A) to the tool – it can be positioned to the left or right – install it in the position most

comfortable for you. Screw the handle on (rotate right / clockwise) firmly.

2. Ensure that the disc guard (B) is positioned in a way to protect you from sparks, debris etc and against

the disc itself if it was to shatter during use. Lock the guard in position using the locking lever (C). If the

locking lever is not holding the guard securely enough, increase tension on the locking screw by rotating

the nut (D) inward (right / clockwise) as required using the supplied spanner.

3. To attach a disc, see Changing the Disc.

Operation

Cutting and Grinding

Fully understand all operational safety warnings before using the tool.

1. Secure the work-piece and, when cutting, ensure nothing is directly below the cut line.

2. Hold the tool firmly using both handles (A and B)

– always use both hands to hold the tool.

3. Press the trigger safety switch (C) using your

finger in and hold it in.

4. Pull the trigger (D) to activate the tool, then using

a steady pressure move the disc into the work-

piece. Maintain sufficient pressure so the disc is

cutting/ grinding freely, however, is not over-

loaded (do not force the tool).

5. Continue the cutting or grinding task until complete, then release the trigger and allow the disc to stop

completely before withdrawing the disc.

Guidelines for Use

General Cutting / Grinding

• When cutting, hold the tool at approximately 30 to 45° to the work-piece

and take extra care to keep the disc as straight as possible during the cut

to reduce disc binding in the cut (slot). Cut slowly, allowing the material

to be fully cut through as you move the tool. Allow the disc to come to a

full stop before removing it from the cut.

• When cutting laminates and other materials where it is important not to damage the surface finish, place

tape over the work-piece along the cut-line to help minimise scratching or

splintering of the top surface.

• When grinding, hold the tool at approximately 15 to 30° to the work-piece.

• When discs become ineffective or reduced in size, replace them.

• Cut or grind / abrade according to the roughness of the disc – do not use excessive pressure or force the

tool. Rougher grade discs produce rougher finishes. For fine or smooth finishes, use a suitable disc.

Cutting Large Work-Pieces

• Large work-pieces require suitable support on either side of the cut to help prevent bending or sagging of

the material. If the work-piece bends where it is being cut, the disc will have a tendency to bind, possibly

causing kick-back. Support the work-piece close to the cut and on both sides of the cut line.

Maintenance and Troubleshooting

Remove the battery from the tool before performing any maintenance. • The tool should be

cool enough to touch before performing maintenance activities. • Wear suitable gloves when

handling discs. • Some maintenance activities described may be beyond the scope of some users. For

procedures that you are not comfortable with or have the tools or experience for, have the unit serviced by a

service centre or qualified technician.

• Clean the tool regularly with a soft cloth – do NOT use water, solvents, abrasives etc. Remove any

debris from the guards and tool ventilation slots using a soft brush.

Changing the Disc

1. Remove the battery from the tool and place the tool on a flat and level surface.

2. Press and hold the spindle lock button (A).

3. Using the supplied pin spanner, rotate the locking collar (B) left (anti-clockwise) to unscrew and remove

it. The disc may rotate slightly until the spindle lock engages and prevents it rotating.

4. Remove the collar (B), disc (C) (if installed) and spigot (D) from the spindle (E).

5. Clean all parts, including the spindle area of the tool of any dust or particles etc – it is essential that this

area is clean, so when the new disc is installed it will run true.

6. Re-install the spigot onto the spindle, with the stepped section that has the driven flats engaging the

drive flats on the spindle.

7. Install the disc onto the spigot and ensure that the rotational arrows are pointing in the direction of

rotation, which is clockwise when looking at the tool from above. Ensure that the bore of the disc is

sitting correctly on the spigot.

8. Re-install the collar (rotate right / clockwise) onto the spindle – use the images for various disc types for

the correct orientation of the collar.

9. Press and hold the spindle lock button, then firmly tighten the collar using the pin spanner.
