Adjusting the saw bench table (fi g. A1)
The table (19) slides up and down manually and is held at the required
height with two locking knobs.
● Loosen the table locking knobs, both main (16) and additional (4),
but do not take them off.
● Set the table to the proper height needed.
● Tighten the table locking knobs. First tighten the main knob (16), then
secure the table in position with the additional knob (4).
Changing from saw bench to mitre saw mode (fi g. A1 & A2)
● Lock the table (19) into highest position.
● Press down the operating handle (2) and pull out the lock down pin
(17), as shown.
● Gently release the downward pressure and allow the head to rise to
its full height.
Instructions for use
@
● Always observe the safety instructions and applicable
regulations.
● Install the appropriate saw blade. Do not use excessively
worn blades. The maximum rotation speed of the tool must
not exceed that of the saw blade.
● Do not attempt to cut excessively small pieces.
● Allow the blade to cut freely. Do not force.
● Allow the motor to reach full speed before cutting.
● Make sure all locking knobs and clamp handles are tight.
● Ensure the material to be sawn is fi rmly secured in place.
● Apply only a gentle pressure to the tool and do not exert side
pressure on the saw blade.
● Avoid overloading.
● Always remove the dust from the machine after use to
ensure the lower guard operates properly.
The attention of UK users is drawn to the "woodworking machines
regulations 1974" and any subsequent amendments.
● When sawing wood and wood products, always connect a dust
extraction device designed in accordance with the relevant
regulations regarding dust emission.
● Although this saw will cut wood and many non-ferrous materials,
these operating instructions refer to the cutting of wood only.
The same guide-lines apply to the other materials. Do not cut ferrous
(iron and steel) materials, fi bre cement or masonry with this saw!
● When cutting non-ferrous materials, always use a suitable D
saw blade with a rake angle of -5°. Make sure to secure the material
in position using a material clamp.
● Make sure to use the kerf plate. Do not operate the machine if the
kerf slot is wider than 10 mm.
Switching on and off (fi g. O)
The on/off switch has a built-in no-volt release function: should the
power be shut off for some reason, the switch has to be deliberately
reactivated.
● To switch the machine on, press the green start button (71).
● To switch the machine off, press the red stop button (72).
Basic saw cuts
Quality of cut
The smoothness of any cut depends on a number of variables, e.g. 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.

@
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 fi bres 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 fi nished.
Dust extraction (fi g. A5)
The machine is provided with a 38 mm dust extraction port on the upper
blade guard.
● Connect a suitable dust extraction device during all sawing operations.
● Whenever possible, connect a dust extraction device designed in
accordance with the relevant regulations regarding dust emission.
Sawing in mitre saw mode
It is dangerous to operate without guarding. Guards must be in position
when sawing.
General handling
- In the mitre saw mode, the sawhead is automatically locked in the
upper "park"-position.
- Squeezing the guard release lever will unlock the sawhead. Moving
the sawhead down retracts the movable lower guard.
- Never seek to prevent the lower guard returning to its park position
when the cut is completed.
- Your saw can cut workpieces up to 220 mm width by 90 mm height.
For the proper cutting capacities, refer to the technical data. The
length of the workpiece should never exceed the base width without
adequate support. The end of the workpiece should never be less
than 160 mm away from the blade without additional clamping means.
- In operation, place your hands no closer than 160 mm from the
blade. When cutting short material (min. 160 mm to the left or the
right of the blade), the use of the optional material clamp is required.
- The minimum length of offcut material is 10 mm.
- When cutting workpieces longer than the table width, make sure that
the workpiece is stable over its full length. Support the protruding
parts of the workpiece as necessary, e.g. using the optional
workpiece extension.
- When cutting UPVC sections, a supporting piece made out of timber
with a complementary profi le should be placed beneath the material
being cut to provide the correct level of support.
Vertical straight cross cut (fi g. A1 & P)
WALT ● Release the mitre lever (10) and depress the mitre latch (9).
E
● Engage the mitre latch at the 0° position and tighten the mitre lever.
● Place the wood to be cut against the fence (6 & 13).
● Take hold of the operating handle (2) and depress the head lock up
release lever (3) to release the head.
● Switch the machine on and allow the saw blade to reach full speed.
● Depress the head to allow the blade to cut through the timber and
enter the plastic kerf plate (8).
● After completing the cut, switch the machine off and wait for the saw
blade to come to a complete standstill before returning the head to its
upper rest position.
Performing a sliding cut (fi g. Q)
The guide rail allows cutting larger workpieces using an out-down-back
sliding motion.
● Release the rail lock knob (17).
● Pull the saw head towards you and switch the tool on.
● Lower the saw blade into the workpiece and push the head back to
complete the cut.
● Proceed as described above.
@
● Do not perform sliding cuts on workpieces smaller than
50 x 100 mm.
