Asphalt and concrete cutters

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.

4.2.4. Cutting Depth Scale

Cutters RZ 122, RZ 172, RZ 202 have the
cutting depth scale. Use the scale as follows:
1. Lower the disc just to touch the ground. In
this position, adjust the "zero" using the
wing nuts below the scale.

4.3. Engine Turning-Off

1. Shift the throttle control lever to idle
position (see point 4.1.1.4)
2. Let the engine to idle for a while to cool
down.

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.
For optimal service life of the cutting disc, the
operator should work carefully and sensitively.
Do not force the machine!
Nevertheless, lifetime of the disc may vary
depending on the material to be cut and other
factors.
2. Alternatively you can just remember the
value on the scale and then add or subtract
required cutting depth as necessary.
The cutting depth is to be set up as follows:
Turn the handle by 1 revolution = disc
rising/lowering by 15 mm.
3. Turn the ignition switch to
point 4.1.1.2).
4. Close the fuel tap (see point 4.1.1.1).
