7.3 Repairing
As already mentioned in Chapter 5 “Initial operation” we recommend
to execute the first repair works on the machine having support of
Blastrac personnel. Doing this together , your maintenance
personnel gets the opportunity to be trained intensely.
We will describe only regular maintenance works that could occur
within the bounds of regular maintenance or work that is required to
replace wear parts.
If you replace parts yourself for specific reason, the following
instructions and work sequence have to be observed.
You should also stock all spare or wear parts that cannot be supplied
quickly. As a rule, production standstill periods are more expensive
than the cost for the corresponding spare part.
Screws that have been removed must be replaced with those of the
same quality (strength, material) and design.
Prior to any repair works on the machine and its drives, secure the
machine against unintentional switching-on. Pull out the mains plug
or rather the spark plug connector in order to do this.
7.4 The scarifying drum
The scarifying drum is a very important component of your scarifier, due
to this you should pay special attention while maintaining and repairing.
The main shaft has to be cleaned and lubricated when you replace the
scarifying drum, so that any rust or sediment can’t complicate your work
when you change the drum the next time.
If the scarifier drum should be disassembled in order to rearrange it in
a different way or to replace wear parts, it is absolute necessary to
observe the quantity of flailes and spacers as described in the
assembly plans shown in chapter 10. Also, pay attention that the
bores on the cover plate for the lateral axle are not worn out and all
screws are tightened. In order to obtain a uniform and perfect
scarifying pattern on the surface , you need to adjust the correct
scarifying working depth, watch correct assembly of the scarifying
