Assembly and adjustment
Prior to assembly and adjustment always unplug the tool.
Unpacking the machine and its parts
When moving the machine, always seek assistance.
The machine is too heavy for one person to handle.
● Remove the loose packaging material from the box.
● Lift the machine out of the box.
● Remove the parts box from the interior of the machine.
● Remove any remaining packing material from the machine.
Mounting the legs (fi g. C1)
With the legs mounted, the machine is suitable for stand-alone placement.
● Turn the machine upside down.
● Pass a coach bolt (47) from the fl at side through the holes into each
of the legs (18).
● Place a lock knob (48) and washer (49) onto the bolts.
● Present a leg (18) to each of the mounting points (46) located at the
edges on the inside of the base. For each leg, make sure that the
lock knob and washer locate at the outside of the open ended slot.
● Tighten the lock knobs.
● Turn the machine straight up. Make sure it is level; adjust the leg
clamping height if required.
Mounting the machine to the workbench (fi g. C2)
With the legs removed, the machine is suitable for placement on a
workbench. To ensure a safe operation, the machine has to be fi xed to
the workbench.

(53).
● To remove, loosen the grommet with a screwdriver (54) and proceed
in reverse order.
Turning the sawhead and table over (fi g. A3, E1 & E2)
● Withhold the saw table with one hand and push the table release
lever (2) to the left (fi g. E1).
● Push the table downwards at the front and swing it over completely
until the motor assembly is uppermost and the indentation engages
in the retaining teeth of the table locking device (20).
● The head assembly is held down by a clamp strap at the front and a
height adjuster (23) at the rear (fi g. A3).
● Remove the strap.
● Rotate the wheel (55) counterclockwise whilst holding down the head
until the "U"-shaped bracket (56) can be disengaged from its seating
(fi g. E2).
● Swing and push the height adjuster up.
● Holding the head fi rmly, allow the spring pressure to take the head
upwards into its rest position.
Mounting the saw blade (fi g. F1 - F3)
The teeth of a new blade are very sharp and can be
dangerous.
Always change blades with the machine in mitre saw mode.
● Insert the Allen key (57) through the hole (58) in the belt casing into
the spindle end (fi g. F1). Place the blade spanner (59) onto the blade
locking screw (60) (fi g. F2).
● The blade locking screw has a left-handed thread, therefore holding
the Allen key fi rmly, turn the spanner clockwise to loosen.
● Depress the head lock up release lever (13) to release the lower
guard (12), then raise the lower guard as far as possible.
● Remove the blade locking screw (60) and the outside arbor collar (61)
(fi g. F3).
● Make sure the inner fl ange and both faces of the blade are clean and
free of dust.
● Install the saw blade (62) onto the shoulder (63) provided on the
inside arbor collar (64), making sure that the teeth at the bottom
edge of the blade are pointing toward the back of the saw (away from
the operator).
● Carefully ease the blade into position and release the lower blade
guard.
● Replace the outer arbor collar.
● Tighten the blade locking screw (60) by turning counter-clockwise
while holding the Allen key steady with your other hand.
● Place the blade spanner and Allen key in their storage position.
After mounting or replacing the blade, always check that
the blade is fully covered by the guard. Make sure the blade
spanner and Allen key have been replaced in their storage
position.
Adjustments for mitre saw mode
Your mitre saw was accurately adjusted at the factory. If readjustment
due to shipping and handling or any other reason is required, follow the
steps below to adjust your saw. Once made, these adjustments should
remain accurate.
Checking and adjusting the blade to the fence (fi g. G1, G2 & H)
● With the head in the vertical position and the bevel clamp handle (22)
released, slacken the locking screw (65) in the rotating table location
plunger (8) (fi g. G1).
