5 MAINTENANCE
A T T E N T I O N
No
cleaning,
maintenance when machine is run-
ning.
Be safe:
Disconnect the machine from
the power supply.
The machine is low maintenance and it contains
only a few parts which need some upkeep
works. Damages that decrease the safety of the
machine must be removed immediately!
5.1
Changing the saw blade
WHEN: Change between saw blades with
different teeth; spare of a damaged, bat-
tered saw blade
ATTENTION: Only use saw blades with:
Max. diameter of 250mm
Max. thickness of 2,8mm.
Max. recommended speed of the saw
blade higher than 5000 rpm.
• Lock the saw aggregate in the highest
position.
Swivel blade guard up
•
• Fix circular saw blade by pressing light-
ly on the locking lever
and rotate the blade by hand until it
clicks into
place.
Rotate the flange bolt with an Allen key
•
clockwise and remove.
NOTE: Left-hand thread
• Take out the flanges.
• Take out the saw blade and remove the
valve spacer.
• Remove the inner flanges, clean all
parts with a rag and anoint it easily.
• Mount the new saw blade (backwards
like you removed the old one). Take
care that the teeth point into the run-
ning direction of the engine!
• For precision mitre cuts we recommend
a saw blade with 60 teeth.
5.2
Changing the carbon
brush
What is the carbon brush? – It is a part of
the electrical engine. It provides the wind-
ings of the engine with electricity. The
carbon brush is a wearing part because it
slides on the collector. That's why there
are carbon brushes included in the deliv-
upkeep,
checks
or
-Fig. 11 (17)-
ery. As a result complaints of the carbon
brushes on guarantee are out of the ques-
tion. When your ZI-KGS250 doesn't start
anymore a battered carbon brush might
be the reason.
Control that by removing the cover cap
(10). Take out the carbon brush. Take
care of the alignment of the brush so that
you are able to mount it correctly.
When the carbon
brush is not long-
er than 4mm the
spring is not able
to push the brush
against the collec-
tor and the engine
does not run anymore.
In that case you have to change the car-
bon brush. Ensure that you mount it cor-
rectly.
