DW678E - Soft start feature

The soft start feature allows the cutting speed to build up slowly, thus reducing the immediate torque reaction transmitted to the belt drive and the operator.

DW678E - Constant speed feature

The constant speed feature maintains the cutting speed under load. This means less noise and a constant cutting speed. Moreover the speed will not increase dramatically when lifting the tool off the workpiece.

DW678E - Electronic brake

his model is equipped with an electronic brake which immediately stops the cutters upon releasing the ON/OFF-switch.

Electrical safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.

Your DeWALT tool is double insulated in accordance with EN 50144; therefore no earth wire is required.

Mains plug replacement (U.K. & Ireland only)

• Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an authorized DEWALT repair agent or a qualified electrician.
• Disconnect the plug from the supply.
• Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.
• Only fit 13 Amperes BS1363A approved plugs fitted with the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for Live (L) (2) and Blue is for Neutral (N) (4).
• Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable firmly and that the two leads are correctly fixed at the terminal screws.

Assembly and adjustment

Prior to assembly and adjustment always unplug the tool.

Adjusting the depth of cut (fig. B)

- Turn the planing depth adjustment knob (4). One revolution of the adjustment knob equals a 4.0 ~mm change in depth. One graduation corresponds to a depth of cut of 0.1 ~mm .

Attaching and removing the parallel fence (fig. A & C)

The parallel fence (13) is used for optimum tool control on narrow workpieces.

• Fit the parallel fence (13) to the threaded hole (6) from either side.
• Tighten the wing bolt (14).
• To remove the parallel fence, proceed in reverse order.

Attaching, removing and adjusting the rabbeting depth stop (fig. A)

• Install the depth stop (8).
- Tighten the wing bolt at the desired height in the threaded hole using the scale.
- To remove the depth stop, proceed in reverse order.

Attaching and removing the stationary stand (DE6661) (fig. D & E)

The stationary stand in figure D is the DE6661. This stand is available as an option as well as the thicknessing and surfacing stand DE80.

• Open the guard (17) on the stationary stand.
• Place the planer on the stationary stand (15).
• Tighten the star knob (16).
• Attach the parallel fence (13) as described.
• To remove the stationary stand, proceed in reverse order.

The part of the cutter that is not being used must always be covered by the guard (17) or by the parallel fence (13).

Removing reversible cutters (fig. F)

• Loosen the three bolts (21) using the spanner supplied.

• Flap the side guard (9) up.

• Slide the cutter (22) out of its holder.

• Reverse the cutter or replace it.

Always replace both cutters.

• Slide the cutter into the holder. At the rabbeting side (i.e. the side where the side guard is mounted), the cutter must be flush with the planing shoe.
• Tighten the three bolts (21).

Fitting the shavings discharge cassette (fig. G)

Although this planer was primarily designed for right-hand side shavings discharge, it can also be used for left-hand side shavings discharge.

For right-hand side shavings discharge, the planer can be used with or without the cassette.

The cassette must be used in combination with the dust extraction adaptor when connecting a vacuum extractor.

- Push the cassette with its head end (23) into the right-hand side shavings discharge outlet (24) until it clicks in place. Please note that the figure shows the left-hand side of the tool.

For left-hand side shavings discharge, the cassette must always be used.

When using left-hand side shavings discharge, always use the dust extraction adaptor and a vacuum extractor as described below to prevent clogging. See fig. G.

• Push the cassette with its head end (23) into the left-hand side shavings discharge outlet (24) until it clicks in place.
• Connect the adaptor (25) to a vacuum extractor.
• To remove the cassette, depress the head end (23) and pull out the cassette.

Instructions for use

Always observe the safety instructions and applicable regulations.

Prior to operation:

• Adjust the depth of cut.
• If necessary, fit and adjust the parallel fence.
• Attach the shavings discharge cassette.

Use sharp cutters only.

Switching ON and OFF (fig. A)

Your Planer is equipped with a safety switch to prevent inadvertent operation.

Your planer is supplied with an adapter for connecting a dustbag or a vacuum extractor.

The dustbag is standard for K-models and available as an option for all other models.

• Attach the dustbag to the shavings discharge cassette using the adaptor for right-hand side ejection only.
• Alternatively, for either left-hand or right-hand side ejection, connect the planer to a vacuum cleaner using the adaptor (25).

When using left-hand side shavings discharge, always connect the planer to a suitable vacuum extractor to prevent clogging.

Planing (fig. A)

• Switch the tool ON as described.
• Slowly move the Planer over the workpiece.

- The feed speed should not be too high, especially when using the maximum depth of cut and planing width.

• Remember that several shallow cuts are better than one deep cut.
• Switch the tool OFF.

Your planer is equipped with a parking shoe (12). After switching OFF the tool can be put down without waiting for the cutters to come to a standstill. The parking shoe can be locked in horizontal position when this feature is not needed.

Stationary use (fig. A & D)

• Switching ON: press the lock-off button (2) and subsequently press the ON/OFF-switch (1).
