Replacing The Table Insert - Scheppach HM254SPX Original Bedienungsanleitung

10.2 Cleaning the moving saw blade guard safety
device (5)
Always check the saw blade guard for debris before
using the machine.
Remove old sawdust and splinters using a brush or
similar tool.

10.3 Replacing the table insert

Danger!
With a damaged table insert (10) there is a risk of small
parts getting stuck between table insert and saw blade,
blocking the saw blade. Immediately replace dam-
aged table inserts!
1. Remove screws at table insert. If required, turn ro-
tary table and incline saw head to be able to reach
the screws.
2. Remove table insert.
3. Install new table insert.
4. Tighten the screws at table insert.
10.4 Brush inspection
Check the carbon brushes after the first 50 operating
hours with a new machine, or when new brushes have
been fitted. After carrying out the first check, repeat the
check every 10 operating hours.
If the carbon is worn to a length of 6 mm, or if the spring
or contact wire are burned or damaged, it is necessary
to replace both brushes. If the brushes are found to
be usable following removal, it is possible to reinstall
them.
When servicing the carbon brushes, open the two
latches counterclockwise (as shown in Figure 21).
Then remove the carbon brushes.
Replace the carbon brushes in the reverse order.
10.5 Changing the saw blade (fig. 1/2/14-17)
Remove the power plug!
Important!
Wear safety gloves when changing the saw blade.
Risk of injury!
• Swing the machine head (4) upwards and lock with
the locking bolt (23).
• Loosen the retaining screw (5a) of the cover using a
Phillips screwdriver (fig. 14).
WARNING!
Do not fully remove this screw.
• Fold the saw blade guard (5) upwards until the saw
blade guard (5) is above the flange screw (28).
• With one hand insert the Allen key (C) in the flange
screw (28).
• Hold the Allen key (C) and slowly close the saw
blade guard (5) until it touches the Allen key (C).
• Firmly press the saw shaft lock (30) and slowly ro-
tate the flange screw (28) in clockwise direction. The
saw shaft lock (30) engages after no more than one
rotation.
• Now, using a little more force, slacken the flange
screw (28) in the clockwise direction.
• Turn the flange screw (28) right out and remove the
outer flange (29).
• Take the blade (6) off the inner flange (31) and pull
out downwards.
• Carefully clean the flange screw (28), outer flange
(29) and inner flange (31).
• Fit and fasten the new saw blade (6) in reverse order.
• Fold the saw blade guard (5) downwards until the
saw blade guard (5) engages in the locking screw
(5a).
• Re-tighten the locking screw (5a).
• Important!
The cutting angle of the teeth, in other words the di-
rection of rotation of the saw blade (6) must coincide
with the direction of the arrow on the housing.
• Before continuing your work make sure that all safe-
ty devices are in good working condition.
• Important!
Every time that you change the saw blade (6), check
to see that it spins freely in the table insert (10) in
both perpendicular and 45° angle settings.
• Important!
The work to change and align the saw blade (6) must
be carried out correctly.
10.6 Adjusting the laser (fig. 19-20)
If the laser (32) ceases to indicate the correct cutting
line, you can readjust the laser. To do so, open the
screws (32b) and remove the front cover (32a). Loosen
the Phillips head screws (E). Set the laser by moving
sideways until the laser beam strikes the teeth of the
saw blade (6).
After adjusting and tightening the laser, mount the front
cover by tightening both screws (32b) by hand.
The machine must be connected to the mains in order
to adjust the laser.
Attention!
Never press the ON/OFF switch (2) when adjusting
the laser. Danger of injury!
