5.11 Vacuum Blower
Scheduled Maintenance
Blower and Vacuum Separator Filter
The vacuum blower operates at an extremely high
RPM and has specific lubrication and maintenance
requirements. It is also very susceptible to damage
from debris because of the tight tolerances in the
blower impellers. Refer to the Maintenance Matrix
in this section and the blower manufacturer’s op-
erating manual for lubrication specifications and
maintenance schedules.
Be sure the vacuum filter is always in good operat -
ing condition so it fully protects the blower from
collecting vacuumed debris internally. If paint
debris ever gets into the blower impellers, use a
paint or lacquer thinner or other non-corrosive
cleaner to remove any residue build-up inside. It
will be necessary to remove the silencer in order
to clean the blower. Remember that if large debris
gets into the blower, it can cause severe damage
to the blower. Refer to Vacuum Separator Filter in
the General Maintenance section of this manual for
instructions on maintaining the vacuum system and
cleaning the filter.
Daily Inspection and Maintenance
• Check for obvious loose mounting nuts and
bolts.
• Check the oil level in the gear end of the
blower. It should be within 1/4” of the overflow
plug threads.
• Grease blower drive end bearings with the
lubricant recommended by the blower manu-
facturer.
• Clean the vacuum filter before each shift. Fil -
ters may be cleaned with a pressure washer
up to 2000 PSI (138 bars). A mild solvent
solution may be used to clean thermoplastic
or tar residue from the filter surface.
• Inspect the filter for holes or thin areas that
could allow vacuumed water or debris to get
into the vacuum blower or silencer. Clean,
secure filtration is necessary to keep your
vacuum blower in good operating condition.
Replace if necessary.
• Check the vacuum separator lid seal. Clean or
replace the seal if necessary.
• Inspect the blades for excessive wear and
damage. Replace blades if necessary.
100 Hour Maintenance (New Blower)
Perform all daily maintenance along with the items
outlined in this section.
• Change blower gear case lubricating oil after
the first 100 hours and every 500 hours there -
after. Service the blower as recommended in
the blower operating manual.
Important:
Make sure to install the safety plug in the
crankcase drain valve when draining is com-
plete. The safety plug prevents crankcase
oil from draining if the valve is accidentally
opened.
200 Hour Maintenance
Perform all daily maintenance along with the items
outlined in this section.
• Inspect and tighten all mounting bolts, hose
clamps and hardware.
• Inspect separator drum wiper blades for ex-
cessive wear and damage. Operate vacuum
system and ensure the blades are sealing
properly.
• Inspect, clean and lubricate the vacuum re-
lief valve (Kunkle valve) to keep it operating
properly.
• Inspect all hoses and fittings for signs of dete -
rioration, chaffing and leaks. Repair or replace
as necessary.
• Tap vacuum hose walls with a dead blow ham-
mer while the system is operating at maximum
vacuum to flex the hose walls and cause built
up debris to break off and be sucked into the
debris tank.
• Inspect and rotate the vacuum hoses 120
0
to
increase the life of the hoses.
500 Hour Maintenance
Perform all daily and 200 hour maintenance along
with the items outlined in this section.
• Change blower gear case lubricating oil. Ser-
vice the blower as recommended in the blower
operating manual.
