an =	m/s2	2.1	2.1	2.1	2.1
Uncertainty K =	m/s2	1.5	1.5	1.5	1.5

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 61029 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

WARNING: The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.

Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Additional Safety Rules for Mitre Saws

• The machine is provided with a special configured power supply cord which can only be replaced by the manufacturer or its authorised service agent.
• Do not use the saw to cut other materials than those recommended by the manufacturer.
• Do not operate the machine without guards in position, or if guards are not in good working order or are not properly maintained.
• Ensure that the arm is securely fixed when performing bevel cuts.
• Keep the floor area around the machine level, well-maintained and free of loose materials, e.g., chips and cut-offs.
• Use correctly sharpened saw blades. Ensure the speed marked on the saw blade is at least equal to the speed marked on the rating plate of the saw.
• Make sure all locking knobs and clamp handles are tight before starting any operation.
• Never place either hand in the blade area when the saw is connected to the electrical power source.

Never attempt to stop a machine in motion rapidly by jamming a tool or other means against the blade; serious accidents can occur.

Before using any accessory, consult the instruction manual. The improper use of an accessory can cause damage.

Use a holder or wear gloves when handling a saw blade or rough material.

Ensure that the saw blade is mounted correctly before use.

Make sure that the blade rotates in the correct direction.

Do not use blades of larger or smaller diameter than recommended. For the proper blade rating, refer to the technical data. Use only the blades specified in this manual, complying with EN 847-1.

Consider applying specially designed noise-reduction blades.

Do not use HIGH SPEED STEEL blades.

Do not use deformed or damaged saw blades.

Do not use any abrasive or diamond discs.

Before each cut, ensure that the machine is stable.

When fitted with a laser, do not replace the laser with a different type. Repairs shall only be carried out by the laser manufacturer or an authorized agent.

Never use your saw without the kerf plate.

- Raise the blade from the kerf in the workpiece prior to releasing the switch.

- Do not wedge anything against the fan to hold the motor shaft.

- The blade guard on your saw will automatically raise when the arm is brought down; it will lower over the blade when head lock up release lever (17) is pushed.

- Never raise the blade guard manually unless the saw is switched off. The guard can be raised by hand when installing or removing saw blades or for inspection of the saw.

- Check periodically that the motor air slots are clean and free of chips.

- Replace the kerf plate when worn. Refer to service parts list included.

- Disconnect the machine from the mains before carrying out any maintenance work or when changing the blade.

- Never perform any cleaning or maintenance work when the machine is still running and the head is not in the rest position.

- When possible, always mount the machine to a bench.

- The front section of the guard is louvered for visibility while cutting. Although the louvers dramatically reduce flying debris, they are openings in the guard and safety glasses should be worn at all times when viewing through the louvers.

- Connect the saw to a dust collection device when sawing wood. Always consider factors which influence exposure of dust such as:

-- type of material to be machined (chip board produces more dust than wood);

-- sharpness of the saw blade;

-- correct adjustment of the saw blade,

-- dust extractor with air velocity not less than 20 m/s.

Ensure that the local extraction as well as hoods, baffles and chutes are properly adjusted.

- Please be aware of the following factors influencing exposure to noise:

-- use saw blades designed to reduce the emitted noise;

-- use only well sharpened saw blades;

• Machine maintenance shall be conducted periodically;

- Provide adequate general or localized lighting;

- Ensure the operator is adequately trained in the use, adjustment and operation of the machine;

- Ensure that any spacers and spindle rings are suitable for the purpose as stated in this manual.

- Refrain from removing any cut-offs or other parts of the workpiece from the cutting area while the machine is running and the saw head is not in the rest position.

- Never cut workpieces shorter than 200 mm.

- Without additional support the machine is designed to accept the maximum workpiece size of: - Height 70 mm by width 300 mm by length 500 mm - Longer workpieces need to be supported by suitable additional table, e.g. DE7080. Always clamp the workpiece safely to the saw table.

- In case of an accident or machine failure, immediately turn the machine off and disconnect machine from the power source.

• Report the failure and mark the machine in suitable form to prevent other people from using the defective machine.

- When the saw blade is blocked due to abnormal feed force during cutting, turn the machine off and disconnect it from power supply. Remove the workpiece and ensure that the saw blade runs free. Turn the machine on and start new cutting operation with reduced feed force.

- Never cut light alloy, especially magnesium.

- Select the correct saw blade for the material to be cut.

- Whenever the situation allows, mount the machine to a bench using bolts with a diameter of 8 mm and 80 mm in length.

The upper part of the left side of the fence can be adjusted to the left to provide clearance, allowing the saw to bevel to a full 48° left. To adjust the fence (3):

• Loosen the plastic knob (29) and slide the fence to the left.
• Make a dry run with the saw switched off and check for clearance. Adjust the fence to be as close to the blade as practical to provide maximum workpiece support, without interfering with the up and down movement of the arm.
• Tighten the knob securely.

WARNING: The guide groove (60) can become clogged with sawdust. Use a stick or some low pressure air to clear the guide groove.

The moveable part of the right side of the fence can be adjusted to provide maximum support of the workpiece near the blade, while allowing the saw to bevel to a full 45° left. The sliding distance is limited by stops in both directions.

To adjust the fence (8):

• Loosen the wing nut (76) to release the fence (8).
• Slide the fence to the left.
• Make a dry run with the saw switched off and check for clearance. Adjust the fence to be as close to the blade as practical to provide maximum workpiece support, without interfering with the up and down movement of the arm.
• Tighten the wing nut (76) to secure the fence in place.

OVERRIDING THE BEVEL STOPS (FIG. K)

The bevel stops facilitate the setting of the saw blade in the vertical position and the 45° bevel position. By overriding the bevel stops, bevel angles can be achieved from 2° right to 48° left.

• To override the bevel stops, first release the saw head and push it slightly to the left, then pull out the override knob (27) and turn it into the override position (62). The override knob automatically clicks in place.
• Set the required bevel angle and secure the head in this position.
• To discontinue the override, turn the override knob (27) back into the bevel stop position (61).

CHECKING AND ADJUSTING THE BEVEL ANGLE (FIG. A1, A2 & I5)

• Make sure the override knob (27) is located in the bevel stop position.
• Loosen the left side fence clamping knob (29) and slide the upper part of the left side fence to the left as far as it will go.
• Loosen the bevel clamp handle (11) and move the saw head to the left. This is the 45° bevel position.
• If adjustment is required, proceed as follows:
• Turn the stop screw (9) in or out as necessary until the pointer (58) indicates 45°.

RAIL GUIDE ADJUSTMENT (FIG. L)

• Regularly check the rails for clearance.
• To reduce clearance, gradually rotate the set screw (64) clockwise while sliding the saw head back and forth.

OPERATION

Instructions for Use

WARNING: Always observe the safety instructions and applicable regulations.

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

The attention of UK users is drawn to the “woodworking machines regulations 1974” and any subsequent amendments.

Ensure the machine is placed to satisfy your ergonomic conditions in terms of table height and stability. The machine site shall be chosen so that the operator has a good overview and enough free surrounding space around the machine that allows handling of the workpiece without any restrictions.

To reduce effects of vibration make sure the environment temperature is not too cold, machine and accessory is well maintained and the workpiece size is suitable for this machine.

Prior to Operation

• Install the appropriate saw blade. Do not use excessively worn blades. The maximum rotation speed of the tool must not exceed that of the saw blade.
• Do not attempt to cut excessively small pieces.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
• Make sure all locking knobs and clamp handles are tight.
• Secure the workpiece.
• Although this saw will cut wood and many nonferrous materials, these operating instructions refer to the cutting of wood only. The same guidelines apply to the other materials. Do not cut ferrous (iron and steel) materials, fibre cement or masonry with this saw!
• Make sure to use the kerf plate. Do not operate the machine if the kerf slot is wider than 10 mm.

Switching On and Off (fig. M)

A hole (65) is provided in the trigger for insertion of a padlock to lock the tool.

• To run the tool, press the on/off switch (1). - To stop the tool, release the switch.

Setting the Variable Speed (fig. M)

DW712

The speed control dial (19) can be used for advance setting of the required range of speed.

• Turn the dial button (19) to the desired range, which is indicated by a number.
• Use high speeds for sawing soft materials such as wood. Use low speeds for sawing metal.

Clamping the Workpiece (fig. V)

WARNING: A workpiece that is clamped, balanced and secure before a cut may become unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the saw is attached to, such as a table or workbench. When making a cut that may become unbalanced, properly support the workpiece and ensure the saw is firmly bolted to a stable surface. Personal injury may occur.

WARNING: The clamp foot must remain clamped above the base of the saw whenever the clamp is used. Always clamp the workpiece to the base of the saw – not to any other part of the work area. Ensure the clamp foot is not clamped on the edge of the base of the saw.

CAUTION: Always use a workpiece clamp to maintain control and reduce the risk of personal injury and workpiece damage.

Use the material clamp (20) provided with your saw. The left or right fence will slide from side to side to aid in clamping. Other aids such as spring clamps, bar clamps or C-clamps may be appropriate for certain sizes and shapes of material.

TO INSTALL CLAMP

1. Insert it into the hole behind the fence. The clamp should be facing toward the back of the mitre saw. The groove on the clamp rod should be fully inserted into the base. Ensure this groove is fully inserted into the base of the mitre saw. If the groove is visible, the clamp will not be secure.
2. Rotate the clamp 180° toward the front of the mitre saw.
3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly clamp the workpiece.

NOTE: Place the clamp on the opposite side of the base when beveling. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE CLAMP DOES NOT INTERFERE WITH THE ACTION OF THE SAW OR GUARDS.

Basic Saw Cuts

VERTICAL STRAIGHT CROSS CUT (FIG. A1, A2 & N)

• Release the mitre lever (4) and depress the mitre latch (5).
• Engage the mitre latch at the 0° position and tighten the mitre lever.
• Place the wood to be cut against the fence (3 & 7).
• Take hold of the operating handle (18) and depress the head lock up release lever (17) to release the head. Press the trigger switch (1) to start the motor.
• Depress the head to allow the blade to cut through the timber and enter the plastic kerf plate (31).
• After completing the cut, release the switch and wait for the saw blade to come to a complete standstill before returning the head to its upper rest position.

PERFORMING A SLIDING CUT (FIG. 0)

The guide rail allows cutting larger workpieces from 50 x 100 mm up to 500 x 1000 mm using an out-down-back sliding motion.

• Release the rail lock knob (13).
• Pull the saw head towards you and switch the tool on.
• Lower the saw blade into the workpiece and push the head back to complete the cut. • Proceed as described above.

WARNING:

- Do not perform sliding cuts on workpieces smaller than 50 × 100 mm .

- Remember to lock the saw head in the rear position the sliding cuts are finished.

VERTICAL MITRE CROSS-CUT (FIG. A1, P)

• Release the mitre lever (4) and depress the mitre latch (5). Move the arm left or right to the required angle.
• The mitre latch will automatically locate at 10° , 15° , 22.5° , 31.62° and 45° both left and right, and at 50° left and 60° right. If any intermediate angle is required hold the head firmly and lock by tightening the mitre lever. • Always ensure that the mitre lever is locked tightly before cutting. • Proceed as for a vertical straight cross-cut.

WARNING: When mitring the end of a piece of wood with a small off-cut, position the wood to ensure that the off-cut is to the side of the blade with the greater angle to the fence; i.e. left mitre, off-cut to the right - right mitre, off-cut to the left.

BEVEL CUTS (FIG. A1, A2 & Q)

Bevel angles can be set from 48° left to 2° right and can be cut with the mitre arm set between zero and a maximum of 45° mitre position right or left.

• Loosen the left side fence clamping knob (29) and slide the upper part of the left side fence (3) to the left as far as it will go. Loosen the bevel clamp handle (11) and set the bevel as desired.
• Tighten the bevel clamp handle (11) firmly. • Proceed as for a vertical straight cross-cut.

Quality of Cut

The smoothness of any cut depends on a number of variables, e.g. the material being cut. When smoothest cuts are desired for moulding and other precision work, a sharp (60 tooth carbide) blade and a slower, even cutting rate will produce the desired results.

WARNING: Ensure that the material does not creep while cutting; clamp it securely in place. Always let the blade come to a full stop before raising the arm. If small fibres of wood still split out at the rear of the workpiece, stick a piece of masking tape on the wood where the cut will be made. Saw through the tape and carefully remove tape when finished.

Body and Hand Position

Proper positioning of your body and hands when operating the mitre saw will make cutting easier, more accurate and safer.

• Never place your hands near the cutting area.
• Place your hands no closer than 150 mm from the blade.
• Hold the workpiece tightly to the table and the fence when cutting. Keep your hands in position until the switch has been released and the blade has completely stopped.
• Always make dry runs (without power) before finish cuts so that you can check the path of the blade.
• Do not cross your hands.
• Keep both feet firmly on the floor and maintain proper balance.
• As you move the saw arm left and right, follow it and stand slightly to the side of the saw blade.
• Sight through the guard louvres when following a pencil line.

CUTTING PICTURE FRAMES, SHADOW BOXES & OTHER FOUR SIDED PROJECTS (FIG. R1 & R2)

TRIM MOULDING AND OTHER FRAMES

Try a few simple projects using scrap wood until you develop a "feel" for your saw. Your saw is the perfect tool for mitring corners like the one shown in fig. R1. The joint shown has been made using either bevel adjustment.

- Using bevel adjustment

The bevel for the two boards is adjusted to 45° each, producing a 90° corner. The mitre arm is locked in the zero position. The wood is positioned with the broad flat side against the table and the narrow edge against the fence.

- Using mitre adjustment

The same cut can be made by mitring right and left with the broad surface against the fence. The two sketches (fig. R1 & R2) are for four side objects only. As the number of sides changes, so do the mitre and bevel angles. The chart below gives the proper angles for a variety of shapes, assuming that all sides are of equal length. For a shape that is not shown in the chart, divide 180° by the number of sides to determine the mitre or bevel angle.

No. of sides Angle mitre or bevel
4	45°
5	36°
6	30°
7	25.7°
8	22.5°
9	20°
10	18°

COMPOUND MITRE (FIG. S1 & S2)

A compound mitre is a cut made using a mitre angle (fig. R2) and a bevel angle (fig. R1) at the same time. This is the type of cut used to make frames or boxes with slanting sides like the one shown in fig. S1.

WARNING: If the cutting angle varies from cut to cut, check that the bevel clamp knob and the mitre lock knob are securely tightened. These knobs must be tightened after making any changes in bevel or mitre.

- The chart shown below will assist you in selecting the proper bevel and mitre settings for common compound mitre cuts. To use the chart, select the desired angle "A" (fig. S2) of your project and locate that angle on the appropriate arc in the chart. From that point follow the chart straight down to find the correct bevel angle and straight across to find the correct mitre angle.

ENGLISH

• Set your saw to the prescribed angles and make a few trial cuts. • Practice fitting the cut pieces together.
• Example: To make a 4 sided box with 25° exterior angles (angle "A") (fig. S2), use the upper right arc. Find 25° on the arc scale. Follow the horizontal intersecting line to either side to get the mitre angle setting on the saw (23°) . Likewise follow the vertical intersecting line to the top or bottom to get the bevel angle setting on the saw (40°). Always try cuts on a few scrap pieces of wood to verify the settings on the saw.

Cutting Base Mouldings

The cutting of base moulding is performed at a 45° bevel angle.

• Always make a dry run without power before making any cuts. - All cuts are made with the back of the moulding laying flat on the saw.

INSIDE CORNER

Left side

• Position the moulding with top of the moulding against the fence.
• Save the left side of the cut.

Right side

• Position the moulding with the bottom of the moulding against the fence.
• Save the left side of the cut.

OUTSIDE CORNER

Left side

• Position the moulding with the bottom of the moulding against the fence.
• Save the right side of the cut.

Right side

• Position the moulding with top of the moulding against the fence.
• Save the right side of the cut.

Cutting Crown Mouldings

The cutting of crown moulding is performed in a compound mitre. In order to achieve extreme accuracy, your saw has pre-set angle positions at 31.62° mitre and 33.85° bevel. These settings are for standard crown mouldings with 52° angles at the top and 38° angles at the bottom.

• Make test cuts using scrap material before doing the final cuts.
• All cuts are made in a left bevel and with the back of the moulding against the base.

INSIDE CORNER

Left side

• Top of the moulding against the fence. - Mitre right. - Save the left side of the cut.

Right side

• Bottom of the moulding against the fence. - Mitre left. - Save the left side of the cut.

OUTSIDE CORNER

Left side

• Bottom of the moulding against the fence. - Mitre left. - Save the left side of the cut.

Right side

• Top of the moulding against the fence.
• Mitre right.
• Save the right side of the cut.

GROOVING (FIG. T)

Your saw is equipped with a grooving stop (12) and grooving depth adjustment knob (15) to allow for groove cutting.

• Flip the grooving stop (12) towards the front of the saw.
• Adjust the grooving depth adjustment knob (15) to set the depth of the groove cut. It might be necessary to release the lock nut (66) first.
• Place a piece of scrap material of approx. 5 cm between fence and workpiece in order to perform a straight groove cut.
