Transport (Fig. 13); Maintenance - Scheppach HM80L Original Bedienungsanleitung

• Firmly press the saw shaft lock (32) and slowly ro-
tate the flange screw (29) in clockwise direction.
The saw shaft lock (32) engages after no more than
one rotation.
• Now, using a little more force, slacken the flange
screw (29) in the clockwise direction.
• Turn the flange screw (29) right out and remove the
outer flange (30).
• Take the blade (6) off the inner flange and pull out
downwards.
• Carefully clean the flange screw (29), outer flange
(30) and inner flange.
• Fit and fasten the new saw blade (6) in reverse or-
der.
• Important! The cutting angle of the teeth, in other
words the direction 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 ta-
ble 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.
8.10 Replacing laser batteries (fig. 11)
• Remove the laser battery cover (34). Remove the
2 batteries.
• Replace both batteries with the same or an equiva-
lent type. Make sure that they are inserted with the
same polarity as the used batteries.
• Close the battery cover.
8.11 Switch ON / switch OFF the laser (fig. 11)
To switch on: Move the ON/OFF (33) switch of the
laser (34) to the "1" position. A laser line is projected
onto the material you wish to process, providing an
exact guide for the cut.
To switch off: Move the ON/OFF switch of the laser
to the "0" position.
8.12 Adjusting the laser (fig. 12)
If the laser (35) ceases to indicate the correct cutting
line, you can readjust the laser. To do so, open the
screws (36) and set the laser by moving sideways to
that the laser beam strikes the teeth of the saw blade
(6).
8.13 Using the clamping handle (fig. 1/2)
• The height of the clamping device (15) can be ad-
justed via the set screw (16).
• Lower the clamping device onto the workpiece.
• Tighten the set screw (16) firmly.
• Turn the clamping handle (38) clockwise to clamp
the workpiece.
• To release the workpiece, proceed in reverse order.

9. Transport (fig. 13)

• Tighten the set screw (7) in order to lock the rotary
table (13)
• Press the machine head (4) downwards and secure
with the stop for cutting depth limiting (25). The saw
is now locked in the lower position.
• Carry the equipment by the transport handle (37).
• When reassembling the equipment proceed as de-
scribed under section 8 - 9.

10. Maintenance

m Warning! Prior to any adjustment, maintenance or
service work disconnect the mains power plug!
General maintenance measures
Wipe chips and dust off the machine from time to time
using a cloth. In order to extend the service life of the
tool, oil the rotary parts once monthly. Do not oil the
motor.
When cleaning the plastic do not use corrosive prod-
ucts.
Cleaning the moving saw blade guard safety de-
vice (5)
Always check the saw blade guard for debris before
using the machine.
Remove old sawdust and splinters using a brush or
similar tool.
Replacing the table insert (fig. 14)
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
damaged table inserts!
1. Remove table insert screws (F).
2. Remove table insert.
3. Install new table insert.
4. Tighten the table insert screws (F).
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 15).
Then remove the carbon brushes.
Replace the carbon brushes in the reverse order.
