8. Insert the blade bolt (F) and tighten it with the 6 mm hex key
(Z) by turning anti-clockwise while holding the 6 mm hex key
(Z) engaged with your other hand (Fig. 8).
9. Remove the two hex keys (Z) and fit them back into their
holder.
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. 1, 2, 9, 10)
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 bars (X) must be perfectly parallel to the table when the
saw head (Y) is fully depressed.
1. Press the lower guard lock-up release lever (B) (Fig. 1).
2. Press the saw head fully to the rear position and measure the
height from the rotating table (N) to the bottom of the outer
flange (E) (Fig. 10).
3. Turn the saw head traverse lock (S) (Fig. 2).
4. Keeping the saw head fully depressed, pull the head to the
end of its travel.
5. Measure the height indicated in Figure 10 again. Both values
should be identical.
6. If adjustment is required, proceed as follows (Fig. 9):
A. Loosen the locknut (KK) in the bracket (LL) under the
upper dust extraction nozzle (R) (Fig. 1) and adjust the
screw (MM) as required, proceeding in small steps.
B. Tighten the locknut (KK).
WARNING: Always check that the blade does not
touch the table at the rear of the slot or at the front
of the rotating arm at 90° vertical and 45° bevel
positions. Do not switch on before having checked
this!
Adjusting the Fence (Fig. 11)
Lift the sliding fence lock lever (I) anti-clockwise to loosen. Move
the sliding fence (Q) to a position that avoids the blade, then
tighten the fence lock lever by turning clockwise.
Checking and Adjusting the Blade to the
Fence (Fig. 2, 12, 13)
1. Slacken the mitre latch (M).
2. Place your thumb on the mitre arm (L) and squeeze the mitre
latch (M) to release the rotating table/mitre arm (N).
3. Swing the mitre arm until the latch locates it at the 0° mitre
position.
4. Pull down the head and lock it in this position using the lock-
down button (W).
5. Check that the two 0° markings (NN) on the mitre scale (O)
are just visible.
6. Place a square (OO) against the left side of the fence (Q) and
blade (H).
WARNING: Do not touch the tips of the blade teeth
with the square.
7. If adjustment is required, proceed as follows:
A. Loosen the mitre scale screws (P) (Fig. 12) and move
the scale/mitre arm assembly left or right until the blade
is at 90° to the fence as measured with the square (OO)
(Fig. 13).
B. Retighten the mitre scale screws (P).
Checking and Adjusting the Blade to the Table
(Fig. 2, 14–16)
1. Loosen the bevel clamp handle (T) (Fig. 14).
2. Press the saw head (Y) to the right to ensure it is fully vertical
and tighten the bevel clamp handle.
3. Place a square (OO) on the table and up against the saw
blade (H) (Fig. 15).
WARNING: Do not touch the tips of the blade teeth
with the square.
4. If adjustment is required, proceed as follows:
A. Loosen the bevel clamp handle (T) and using a hex key
(Z), turn the vertical position adjustment stop screw (QQ)
in or out until the blade is at 90° to the table as measured
with the square.
B. If the bevel pointer (RR) does not indicate zero on the
bevel scale (U), loosen the bevel scale screws (PP) that
secure the scale and move the scale as necessary.
Checking and Adjusting the Bevel Angle
(Fig. 2, 14, 16)
The bevel override allows the maximum bevel angle to be set at
45° or 48° as required.
1. Make sure the override knob (SS) is located in the left
position.
2. Loosen the bevel clamp handle (T).
3. Standing in front of the machine, move the saw head (Y) to
the left.
4. This is the 45° bevel position.
5. If adjustment is required, turn the 45° bevel adjustment stop
screw (TT) using a 4 mm hex key (Z), in or out as necessary
until the bevel pointer (RR) indicates 45°.
WARNING: The guide grooves can become clogged
with sawdust. Use a stick or some low pressure air to
clear the guide grooves.
Prior to Operation
WARNING:
• 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.
