4. Perform the Operation & Leakage Tests listed in this
publication.
Every 3,600 operating hours, 100,000 miles or one (1)
year:
1. With the air system pressure at 0 p.s.i., drain collected
contaminants for disposal.
2. Visually check for physical damage to the PuraGuard
QC
™
filter such as chaffed or broken air hoses and
broken or missing parts.
3. Replace the cartridge (see Maintenance Kits, Figure
5). Do not use the drain valve to remove the cartridge.
4. Check mounting bolts for tightness. Re-torque to 160-
200 in-lbs.
5. Perform the Operation & Leakage Tests listed in this
publication.
The PuraGuard QC ™ oil coalescing filter has two female
pipe thread air connections: one supply, one delivery —
identified by their relationship to the arrow symbol showing
air flow on the PuraGuard QC
™
filter top (see Figure 1).
Note: The PuraGuard QC
™
filter is not recommended to be
used in conjunction with an alcohol evaporator or injector. The
PuraGuard QC
™
oil coalescing filter will remove the liquid or
aerosol alcohol introduced, defeating the purpose of the
evaporator/injector and requiring the sump to be drained more
often than normal.
FILTER BYPASS
(refer to Figure 4)
If a situation occurs where the ability of the filter to allow air
to pass is impaired and causes a pressure difference of
approximately 20 p.s.i. between the air entering the filter
element and exiting, the filter will move downward against
the spring. The air entering will then be able to bypass the
filter element.
PREVENTIVE MAINTENANCE
Important: Review the warranty policy before performing
any intrusive maintenance procedures. An extended warranty
may be voided if intrusive maintenance is performed during
this period.
Because no two vehicles operate under identical conditions,
maintenance intervals will vary. Experience is a valuable
guide in determining the best maintenance interval for a
vehicle.
Every 300 operating hours, 8,000 miles or one (1)
month:
1. With the air system pressure at 0 p.s.i., use the drain
valve to collect contaminants for disposal. Do not open
the valve beyond shoulder stop. This could loosen the
handle.
2. Visually check the PuraGuard QC ™ filter for broken or
missing parts.
3. Check mounting bolts for tightness. Re-torque to vehicle
manufacturers guidelines.
