Operating
Start the blower and check the appropriate parameters as listed in the
maintenance schedule under the Maintenance section.
Stopping the Blower
When stopping the blower, if possible, remove all vacuum and pressure from
the blower.
Cold Weather Operation
During very cold weather conditions, always warm the blower before
operating at full rated vacuum or pressure. Damage to the blower can result
from operating for short intervals in very cold weather conditions.
If using a coupler with a rubber jaw or sleeve in shear during extremely cold
weather, take note that elastomeric materials become stiffer in cold weather.
This results in a reduction of the shear protection in the event of a lock up of
the blower because the jaw or sleeve can handle more torque before giving
way.
If hydraulically driving the blower, allow the hydraulic fluid to warm up
before operating the blower at full load. Use the correct viscosity of
hydraulic oil for the operating temperature as recommended by the
manufacturer of your system.
Before starting blower, verify the shaft rotates freely by hand. Water can
condense and freeze in the blower cylinder without warning causing a stall
condition at start up.
Check the intake filter and air intake daily. If snow is present, check the air
intake more frequently.
DO NOT thin out the oil in the gear cases with any other fluids such as
Kerosene. Use the recommended oil for the operating temperatures.
If temperatures are so cold that the blower cannot warm up, enclose the
blower allowing for sufficient clearance from parts to prevent contact with
hot or moving components.
