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.

ASSEMBLY

WARNING: To reduce the risk of injury, turn unit off

and disconnect machine from power source before

installing and removing accessories, before adjusting or

changing set-ups or when making repairs. Be sure the

trigger switch is in the OFF position. An accidental start-up

can cause injury.

Unpacking

The motor and guards are already assembled onto the base.

Cable clamp (fig. 7)

Insert the cable (bb) into the cable clamp (aa). Allow enough cable for the saw head to travel, then tighten the clamp by means of the screw.

Bench mounting (fig. 2)

1. Holes (v) are provided in all four feet to facilitate bench mounting. The holes are provided to accommodate different sizes of bolts. Use either hole; it is not necessary to use both. Always mount your saw firmly to prevent movement.

To enhance the portability, the tool can be mounted to a piece of 12.5mm or thicker plywood which can then be clamped to your work support or moved to other job sites and reclamped.

1. When mounting your saw to a piece of plywood, make sure that the mounting screws do not protrude from the bottom of the wood. The plywood must sit flush on the work support. When clamping the saw to any work surface, clamp only on the clamping bosses

where the mounting screw holes are located. Clamping at any other point will interfere with the proper operation of the saw.

1. To prevent binding and inaccuracy, be sure the mounting surface is not warped or otherwise uneven. If the saw rocks on the surface, place a thin piece of material under one saw foot until the saw is firm on the mounting surface.

Mounting the saw blade (fig. 8-10)

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF position. An accidental start-up can cause injury.

1. Slacken the litre latch (m) and subsequently lift it up.
2. Engage the litre latch (m) at the 0^ position and fasten the litre latch.

3. Place the wood to be cut against the fence (p).

4. Take hold of the carrying handle (c) and press the guard lock up release lever (b) to release the guard. Press the trigger switch (a) to start the motor. It is recommended to start the cut near the fence.

5. Depress the head to allow the blade to cut through the timber and enter the plastic kerf plate (k).
6. When the head is fully depressed, slowly pull it across to complete the cut.
7. 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.

WARNING:

• For some types of plastic profiles, it is advisable to follow the sequence in reverse order.
• The lower blade guard is designed to close quickly when the lever (b) is released. If it does not close within 1 second, have the saw serviced by an authorized DEWALT repair agent.

VERTICAL MITRE CROSS-CUT (FIG.21)

1. Squeeze the litre latch (m). Move the arm left or right to the required angle.
2. The litre latch will automatically locate at 0^ , 15^ , 22.5^ , 31.62^ , 45^ and 50^ both left and right. If any intermediate angle is required hold the head firmly and lock by fastening the litre latch.
3. Always ensure that the metre lock lever is locked tightly before cutting.
4. 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 litre, off-cut to the right right litre, off-cut to the left

BEVEL CROSS-CUTS (FIG. 18, 22)

Bevel angles can be set from 0^ to 48^ to the left. Bevels up to 45^ can be cut with the litre arm set between zero and a maximum of 45^ litre position right or left.

1. Loosen the bevel clamp handle (t) and set the bevel as desired.
2. Set the override button (ee) if required.
3. Hold the head firmly and do not allow it to fall.
4. Tighten the bevel clamp handle (t) firmly.
5. Proceed as for a vertical straight cross-cut.

Quality of cut

The smoothness of any cut depends on a number of variables, i.e. 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.

Clamping the workpiece (fig. 3)

1. Whenever possible, clamp the wood to the saw.
2. For best results use the material clamp (kk) made for use with your saw. Clamp the workpiece to the fence whenever possible. You can clamp to either side of the saw blade; remember to position your clamp against a solid, flat surface of fence.

WARNING: Always use a material clamp when cutting non-ferrous metals.

This cut is a combination of a litre and a bevel cut. This is the type of cut used to make frames or boxes with slanting sides like the one shown in figure 23.

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

• The chart shown below will assist you in selecting the proper bevel and litre settings for common compound litre cuts.
• To use the chart, select the desired angle “A” (fig. 24) 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 metre angle.

1. Set your saw to the prescribed angles and make a few trial cuts.
2. Practice fitting the cut pieces together.

Example: To make a four-sided box with 25^ exterior angles (angle "A") (fig. 24), use the upper right arc. Find 25^ on the arc scale. Follow the horizontal intersecting line to either side to get the litre 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.

WARNING: Never exceed the compound litre limits of 45^ bevel with 45^ left or right litre.

Support for short and long pieces (fig. 3)

CUTTING SHORT MATERIAL

It is advisable to use the length stop (mm) for short workpieces both for batch sawing and for short individual workpieces of different lengths. The length stop can only be used in conjunction with a pair of optional guide rails (ii).

CUTTING LARGE MATERIAL

WARNING: To reduce the risk of injury, always support long workpieces.

Figure 3 shows the ideal configuration for sawing long workpieces when the saw is used free-standing (all items available as an option).

These items (except the legstand and the material clamp) are required both on the infeed and the outfeed side:

• Legstand (nn) (supplied with mounting instructions).
  Guide rails (500 or 1,000 mm) (ii).
• Stands (mm) to support the guide rails. Do not use the stands to support the machine! The height of the stands is adjustable.
  Material support plates (jj).
• Table end plate (hh) for supporting the rails (also when working on an existing bench).
  Material clamp (kk).

• Swivelling stop (II).

• Place your saw on the legstand and fit the guide rails.

• Firmly screw the material support plates (jj) to the guide rails (ii).

• The material clamp (kk) now functions as a length stop.

• Install the table end plates (hh).
• Install the swivelling stop (I) to the rear rail.
• Use the swivelling stop (I) to adjust the length of medium and long workpieces. It can be adjusted sideways or swung out of the way when not in use.

Dust extraction (fig. 1, 6)

WARNING: Whenever possible, connect a dust extraction device designed in accordance with the relevant regulations regarding dust emission.

Connect a dust collection device designed in accordance with the relevant regulations. The air velocity of externally connected systems shall be 20m / s + ·2m / s . Velocity to be measured in the connection tube at the point of connection, with the tool connected but not running.

A separate dust kit is available as an option (DE7777).

1. Fit the dust extraction tubes (qq) to the nozzles (q); the longer hose to upper nozzle.
2. Connect the hoses to the three-way connector (rr).

Transporting (fig. 1)

WARNING: In order to conveniently carry the litre saw, the base is provided with two hand indentations (ff).

1. To transport the saw, set the bevel and metre positions to 0^ .
2. Press the lower guard lock up release lever (b) (fig.1).
3. Press the head down and press the lock down button (w) (fig. 2).
4. Bring the saw blade to rest position and press the traverse lock (r).
