• ALWAYS turn off the machine and discon-
nect the power source before installing or
replacing the blade.
• ONLY use correct size tools for installing
Blade.
• ONLY use good quality diamond blades
according to machines features and for the
material to be cut.
• Always use the required blade diameter
because it affects the maximum cutting
depth and the useful cutting length.
• Be sure the diamond blade is correctly
balanced and tensioned and is properly
tightened on arbor.
• Avoid cutting pieces of material that are
too big, too small, or difficult to set prop-
erly on working table.
• The blade life depends on its daily use, type and thick-
ness of piece to cut and proper water flow to keep it
cool.
• The blade should be replaced whenever the cutting
quality is not optimal because it could be worn out or
deformed. Operating with a worn out or defective
blade could be dangerous.
• Replace the blade or install the profile wheel by stand-
ing in front of the machine as follows.
1. Tilt the blade 45° and loosen the 2 screws
A (Fig. 7)
behind the blade guard with a 10mm wrench and re-
move the guard
B (Fig. 7)
.
2. Hold the motor spindle
C (Fig. 7)
and unscrew the blade
shaft nut (CW) clockwise using the 30mm wrench
D
(Fig. 7)
supplied (only on FRS 51). For the FS-30 &
38, hold the motor shaft from turning with a 6mm hex
key inserted into the back side of the motor and loosen
the nut (CW) with a 19mm wrench.
3. Once the blade is removed, check the outer flange
E
(Fig. 7)
and inner flange interior surfaces, and if needed,
replace or clean them to remove any debris that might
prevent the blade from properly seating inside the
flanges.
Note : When using the thick-cored profile wheel on the
FRS 51, do not use the outer flange
E (Fig. 7)
.
4. Mount the new blade in the direction of the rotation
arrow marked on the blade
F (Fig. 7).
It must be the
same direction as the arrow on the blade guard. (clock-
wise from the front).
5. After installing the new blade or profile wheel, be sure
to securely tighten the nut counter-clockwise with the
correct wrench while holding the motor spindle.
6. Before using the machine be sure the blade guard
is securely in place. Re-install the blade guard
B (Fig.
7)
and securely tighten the 2 screws
A (Fig. 7)
using an
M10 wrench.
