6.1 Normal Operation
Normally, starting and operating the scarifier is the same procedure as described
in Section 5 “Preparation/Starting”.
Scarifying should be carried out in parallel tracks and in such a way that the dust
hose and the electric cable do not become twisted. For further details, see
Section 6.3 “Recommended Scarifying Directions”.
To protect against unnecessary damage, ensure that no
vehicles, such as forklifts, can drive over the electrical cable or
the dust hose.
6.2 Information on the Drive Speed
Choosing the correct drive speed is crucial in order to obtain the desired surface
profile. If the surface is uneven (e.g. different degrees of hardness or coatings
with different thickness) the drive speed can be varied during scarifying to obtain
a uniform surface profile.
The correct drive speed will depend on the material of the surface being scarified
and the desired surface profile.
To select the correct drive speed:
1. Set the desired penetration depth by means of the depth setting
adjustment wheel.
2. Inspect the surface, and begin scarifying with a relatively fast drive
speed.
3. Begin to slow the drive speed until the desired surface profile is being
obtained.
