Never use a light socket.
Never connect the live (L) or neutral (N) wires to the earth pin
marked E or .
For 115 V units with a power rating exceeding 1500 W, we recommend to
fit a plug to BS4343 standard.
Using an extension cable
If an extension cable is required, use an approved extension cable suitable
for the power input of this machine (see technical data). The minimum

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 carton, pull out the arm and place a piece of wood (24) under
the edge of the table (fig. B).
• Assemble the legs (5) using the nuts, bolts and flat washers from the
skinpack as shown. Do not yet tighten.
• Mount the traverse rails (25).
• Firmly tighten all fasteners.
• Tilt the assembly to upright position.
The machine must be level and stable at all times.
Mounting the height adjustment crank (fig. A1)
• Mount the height adjustment crank (11) on top of the column (8) using
the cross head screw.
Mounting the roller head assembly (fig. A1 & C)
• 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 (26) and remove the end-cap (13) (fig. C).
• Roughen the bearing tracks (27) using a steel wool pad and remove
any dust with a dry cloth (fig. C).
• Make sure that the riplock (15) is released (fig. A1).
• Carefully insert the bearings (28) of the roller head assembly (21) 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. A2 & D)
• Remove the cross head screw (29).
• Mount the cable support (23) and refit the cross head screw (29).
• Fit the cable (30) using the cable clamp (31).
Allow for the arm movement in horizontal and vertical direction.
The saw table (fig. E1 - E4)
Mounting the table supports (fig. E1)
Figure E1 shows the correct position of the table supports. All supports
are mounted using M8 x 16 bolts and corresponding nuts and with a D8
Belleville washer at the front, but not at the rear.
• Mount the 40 mm triangular support (32) to the side of the table base (33).
• Mount the two 30 mm triangular table supports (34) to the front of the
table base.
• Mount the two 75 mm straight table supports (35) provided with a
rectangular recess (36) as shown. Note that these do not protrude
60
from the rear of the table base (33).
• Do not yet tighten the bolts.

Adjusting the table supports using the arbor (fig. A1 & E2)
15
• Release the bevel clamp lever (37) and pull out the bevel latch (38) (fig. E2).
15
• Turn the motor to vertical position and lock it using the bevel latch (38)
20
and the bevel clamp lever (37).
-
• Loosen the mitre clamp lever (10) (fig. A1) to rotate the arm until the
-
arbor (39) is right above the outer front edge of one of the straight table
supports.
• Carefully lower the arm until the arbor just touches the table support
and tighten the corresponding nut of the table support manually.
• Repeat this procedure at the rear edge and for the other table support.
• Check again using the motor arbor.
• Firmly tighten all fasteners.
• Bring the arm back to the central position and lock it.
Adjusting the central table support (fig. E3)
• Place a level over the two straight table supports (35).
• Loosen the bolts (40) in the central table support (41).
• Adjust the central table support using an Allen key until it just touches
the level.
• Firmly tighten all fasteners.
Mounting the fixed table section (fig. E1 & E4)
The standard position of the table top sections is shown in
figure E4.
Depending on the required depth of cut, the fence (6) can also be
positioned between the strips (18).
• Place the fixed table section (4) on the table base as shown and check
that the holes in the middle locate over the adjustment screws in the
central table support.
• Use the M8 x 30 bolts and D8 flat washers at the top and D8 Belleville
washers at the bottom.
• Manually tighten all bolts in the fixed table section (4) except for the five
front bolts and the bolt in the large central hole.
• Place the fence (6) and the strips (18) on the table base (33) (fig. E1).
• Mount the table clamps (7) (fig. E4) to the rear of the straight table
supports (35) (fig. E1).
• Tighten the table clamps.
• Firmly tighten all bolts in the table top.
