Cooler Maintenance; Motor Maintenance - Hertz HGS 2-15 Operator's Handbook Manual

Do not expand the diameter of the scavenge orifice, otherwise the capacity of your
o
compressor reduces.
THE MAINTENANCE OF COOLER
For keeping the cooler clean, you should not hinder the cleaning of the panel filter.
o
As the cooling air passes between the cells of the cooler, small amount of dust goes between
o
the cooler cells and this start to block the cells. Clean this by spraying compressed air
between the cells from the opposite of cooler (from outside to inside).
When the dust between the cells mixes with oil, it may get hardened by sticking. In this case
o
clean this by spraying an industrial cleaner between the radiators cells. For performing this, if
necessary remove the cooler.

MOTOR MAINTENANCE

For long life and effective use of the electrical motors you should consider a few important points.
Make the grounding of the compressor properly.
o
Do not change the pressure related with the compressor operation, thermal current and time
o
adjustments. When the adjusted value is exceeded, the motor current will increase as the load
will increase. This situation may cause burning down of your motor.
Do not use products like the belts, separator and oil filters that have complete their service life.
o
The maintenance activities that are no performed on time will force the system mechanically
and therefore increase the load of your motor and compressor and shorten its life.
Keep the cooling fan, ventilation channels and the screen of the fan protective cover clean.
o
Your elevation from sea level and medium temperature directly affects the cooling coefficient
o
of the motor. In standard, your motor operates without problem at 1000 meters altitude and at
40 C° medium temperature. You may have to review the loading ratio at higher altitudes and
warmer places.
