Three-phase machines should be wired directly into the mains by a
suitably qualified electrician.
Voltage drops
Inrush currents cause short-time voltage drops. Under unfavourable power
supply conditions, other equipment may be affected.
If the system impedance of the power supply is lower than 0.25
disturbances are unlikely to occur.

Assembly and adjustment

• Prior to assembly and adjustment always unplug the tool.
• For optimum performance of your saw, it is of vital importance
to follow the procedures in the paragraphs below.
Assembling the legstand (fig. A1 & B)
The legstand components and fasteners are packed separately.
• Remove all parts from the package, except for the arm (12).
• Lock the arm using the mitre clamp lever (10).
• Tilt the machine backwards off the pallet and lie it with the rear of the
column (8) on the floor.
• Using the M10 x 20 socket head screws, nuts and washers,
fasten one leg (3) to each corner of the table base (25).
• Firmly tighten all fasteners.
• Tilt the assembly to upright position.
The machine must be level and stable at all times.
Fitting the switch boxes
DW728 - Fitting the ON/OFF-switch (fig. A1)
The ON/OFF-switch (1) is mounted on a bracket which must be fitted to
the left-hand side leg using the fasteners on the bracket. The switch box
also contains the brake control unit.
• Place the red button of the ON/OFF-switch at the bottom.
• Fit the bracket in the holes in the leg (two at the top and one at the bottom).
DW729 - Fitting the ON/OFF-switch and isolating switch (fig. A1 & A2)
The switch box of this model also contains an isolating switch (2) (fig. A2).
• Proceed as for the DW728.
Mounting the height adjustment crank (fig. C1 - C2)
• Rotate the arm to the central position.
• Press the mitre latch lever (9) down as shown (fig. C1).
• Tighten the mitre clamp lever (10).

• Introduce the height adjustment crank (11) into the column (8) as
shown until the crank engages in the nut inside the column.
• Turn the height adjustment crank clockwise until it is fully seated (fig. C2).
• Align the mitre scale (26) with the pointer (27) and tighten the three
screws (28) inside the height adjustment crank.
Mounting the roller head assembly (fig. A1 & D)
• Rotate the height adjustment crank (11) in the direction of the + to raise
the arm (12) as far as it will go (fig. A1).
• Remove the two Allen screws (29) and remove the end-cap (13) (fig. D).
• Roughen the bearing tracks (30) using a steel wool pad and remove
any dust with a dry cloth (fig. D).
• Make sure that the riplock (15) is released (fig. A1).
• Carefully insert the bearings (31) of the roller head assembly (16) into
the bearing tracks.
• Move the roller head in the bearing tracks to check that it runs smoothly.
• Check that the riplock will lock and release the roller head as required.
• Replace the end-cap (13) immediately.
Mounting the cable support and cable clamp (fig. E)
• Remove the cross head screw (32).
• Mount the cable support (24) with the cable (33) and refit the cross
head screw (32).
The saw table (fig. A2, F1 - F3)
Mounting the triangular supports (fig. A2 & F1)
,
Figure F1 shows the correct position of the triangular supports.
The supports are mounted using M8 x 16 bolts and corresponding nuts
and with D8 flat washers at the front, but not at the rear.
• Mount the triangular supports (34) with the flat side to the front of the
table base (25).
• Mount the straight supports (35) to the flat side of the triangular
supports (34) as shown.
• Fit the two table extensions (19) to the supports by passing M8 x 30
slotted head screws with premounted washers through the four holes
in the table extensions (fig. A2).
• Firmly tighten all fasteners.
Adjusting the table top parallel with the arm tracks using the arbor
(fig. F2 & F3)
• Insert an Allen key (36) into the arbor (37) and loosen the arbor nut (38)
using the 41 mm spanner (39) by turning clockwise (fig. F2).
• Clamp a piece of wood between the flanges (41) and (42) to be used
as a height indicator and tighten the arbor nut (38).
• Loosen the mitre clamp lever (10) and the mitre clamp latch (9) (fig. F3).
• Loosen the height adjustment clamp (40).
• Rotate the arm until the piece of wood is right above one of the
positions marked in figure F3.
• Carefully lower the arm until the arbor just touches the table top and
skim the arm across to check all positions.
• If adjustment is required, proceed as follows:
• Place the 17 mm box spanner over the nut in the relevant hole in the table.
- table up
- table down
• Firmly tighten all fasteners.
• Slacken the bolts securing the straight supports to the triangular
supports.
• Place a level over the two table extensions (19).
• The front of the extension tables must be flush with the front of the
fixed table top.
• Adjust the position using the horizontal slotted holes in the triangular
supports and the vertical slotted holes in the straight supports.
• Firmly tighten all fasteners.
• Bring the arm back to the central position and lock it.
