5.13 Vacuum Blower
Scheduled Maintenance
Blower and Filter Canister
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 Canister & 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 and
drain the filter canister at least once every
2 hours of operation. Filters 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 canister door seal. Clean
or replace the seal if necessary.
500 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 crank -
case drain valve when draining is complete.
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.
• Check pulley clearances and drive belt tension.
• Inspect and tighten all mounting bolts, hose
clamps and hardware.
• Lubricate drain ball valve. Make sure to open
and close all ball valves at least once every
200 hours to keep them free and operating
properly.
• Inspect, clean and lubricate the vacuum relief
valves to keep them 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.
