4.2. Operation
4.2.1. Selection of the Cutting Disc
For safe and efficient operation, right selection
of the cutting disc is highly important. Choose a
high-quality
diamond
cutting
disc
and
appropriate type depending on the material to be
cut (asphalt, concrete).
Cutting discs of most suppliers are divided in
quality
categories
(standard/profi
etc.),
sometimes also according to length and height
of the diamond segments, spacing, etc.
Cutting disc diameter is to be selected according
to the type of the machine; if possible, choose
always the maximal allowed diameter (RZ 120
350 mm, RZ 170 450 mm). The spindle speed is
adjusted for this size to keep optimal
circumferential cutting speed of the disc.
4.2.2. Fastening of the Cutting Disc
1. Turn off the engine and open the disc cover.
2. Use the enclosed wrenches to hold the
spindle and unscrew the fastening nut.
NOTE: Left thread!
3. Fit the cutting disc on the spindle and secure
it.
4. Close the disc cover and secure it.
4.2.3. Cutting
1. Have the disc raised above floor. Start the
engine and set full throttle.
2. Open the water tap to engage sprinkling.
3. Move the machine to the beginning of the
cut.
4. Lower slowly the disc into the cut, till
required cutting depth is reached.
5. Sensitively push the machine forward and
follow the marked path (use the guide).
6. The machine can only cut in straight
direction. In case the direction must be
changed, raise the disc from the cut, take
new direction and lower the disc again.
7. At the end of the cut, raise the disc, set the
throttle to idle.
NOTE! The cutting disc should be sprinkled
all the time. Follow the water level in the
tank and timely add water as necessary. Dry
cutting may cause fast damage to the disc.
