Fitting a Mains Plug to 115 V Units
(U.K. and Ireland Only)
• The plug fitted should be comply with BS EN60309 (BS4343),
16 Amps, earthing contact position 4h.

WARNING: Always ensure that the cable clamp is correctly and securely fitted to the
sheath of the cable.
Using an Extension Cable
If an extension cable is required, use an approved 3–core extension cable suitable for the
power input of this tool (see Technical Data). The minimum conductor size is 1.5 mm
maximum length is 30 m.
When using a cable reel, always unwind the cable completely.
ASSEMBLY

WARNING: To reduce the risk of injury, turn unit off and disconnect machine
from power source before installing and removing accessories, before adjusting
or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can cause injury.
Unpacking
The motor and guards are already assembled onto the base.
Cable Clamp (Fig. F)
Insert the cable 28 into the cable clamp 27
then tighten the clamp by means of the screw.
Bench Mounting (Fig. B)
1. Holes 22 are provided in all four feet to facilitate bench mounting.
Two different sized holes are provided to accommodate different sizes of bolts. Use either
hole; it is not necessary to use both. Bolts with a diameter of 8 mm and 80 mm in length
is suggested. Always mount your saw firmly to prevent movement. To enhance the
portability, the tool can be mounted to a piece of 12.5 mm or thicker plywood which can
then be clamped to your work support or moved to other job sites and reclamped.
2. When mounting your saw to a piece of plywood, make sure that the mounting screws do
not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping the saw to any work
surface, clamp only on the clamping bosses where the mounting screw holes are located.
Clamping at any other point will interfere with the proper operation of the saw.
3. To prevent binding and inaccuracy, be sure the mounting surface is not warped or
otherwise uneven. If the saw rocks on the surface, place a thin piece of material under one
saw foot until the saw is firm on the mounting surface.
Mounting the Saw Blade (Fig. A, G–I)

WARNING: To reduce the risk of injury, turn unit off and disconnect machine
from power source before installing and removing accessories, before adjusting
or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental
start-up can cause injury.
WARNING: The teeth of a new blade are very sharp and can be dangerous.

WARNING: Be aware the saw blade shall be replaced in the described way only. Only use
saw blades as specified under Technical Data; Cat.no.: DT4320 is suggested.
1. Insert the 6 mm hex key 26 into the opposite location of the blade shaft and hold
it (Fig. G).
2. Loosen the blade bolt 6 by turning clockwise. Remove the blade bolt and the outer
flange 5 .
3. Press the lower guard lock up release lever
remove the saw blade 8 .
4. Install the new saw blade onto the shoulder provided on the inner flange
that the teeth at the bottom edge of the blade are pointing towards the fence (away from
the operator).
5. Replace the outer flange 5 , making sure that the location lugs
one on each side of the motor shaft.
6. Tighten the blade bolt 6 by turning anti-clockwise while holding the 6 mm hex key
engaged with your other hand (Fig. I).
ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off and disconnect machine
from power source before installing and removing accessories, before adjusting
or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can cause injury.
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.
Adjusting the Traverse Bars for Constant Cutting Depth
(Fig. A, B, J, L)
The blade must run at a constant cutting depth along the full length of the table and must not
touch the fixed table at the rear of the slot or at the front of the rotating arm. To achieve this,
the traverse arms must be perfectly parallel to the table when the saw head is fully depressed.
1. Press the lower guard lock up release lever
2
. Allow enough cable for the saw head to travel,
2 to raise the lower blade guard 7 and
33 making sure
45 are engaged correctly,
