6. Maintenance
Pay attention to Chapter 3
"Safety"
during maintenance and repair works.
Failures due to inadequate or incorrect maintenance may generate very
high repair costs
and long standstill
periods of the dust collector.
Regular
maintenance therefore is imperative.
Operational safety and service life of the dust collector depend, among other things, on proper maintenance.
The following table shows recommendations about time, inspection and maintenance for the normal use of the
dust collector.
The time indications are based on uninterrupted operation. When the indicated number of working hours is not
achieved during the corresponding period, the period can be extended. However a full overhaul and a technical
inspection must be carried out at least once a year, consisting of inspection of filters for damage, air tightness
of the machine and proper function of the control mechanism. This technical inspection shall be carried out by
the manufacturer or an instructed person.
Due to different working conditions it can’t be foreseen how frequently inspections for wear check’s,
inspection, maintenance and repair works ought to be carried out. Prepare a suitable inspection schedule
considering your own working conditions and experience.
Pay attention to unusual noises or strong vibrations. Check for the cause of every big change. Call a technician
if you have doubts about the cause or when a repair without a technician seems not possible without damages.
Only use genuine Blastrac spare parts.
Our specialists will be happy to assist you with more advice.
