7.2 REGULAR MAINTENANCE
A good maintenance program will add years of service to your blower.
A newly installed blower should be checked frequently during the rst month of operation, especially
lubrication. With blower at rest, check oil level in both the gear (drive) end and free (non-drive) end of the
blower and add oil as needed. Complete oil changes are recommended every 1000-1200 operating hours,
or more frequently depending on the type of oil and operating temperature. Also change the oil more
frequently if pumping corrosive vapors or where excessive operating temperatures are encountered. The
following is recommended as a minimum maintenance program.
DAILY WEEKLY MONTHLY
1. Check and maintain oil level,
and add oil as necessary.
2. Check for unusual noise or
vibration (See Troubleshooting)
1. Clean all air filters. A clogged air filter
can seriously affect the efficiency of the
blower and cause overheating and oil
usage.
2. Check relief valve to assure it is
operating properly.
1. Inspect the entire system for leaks.
2. Inspect condition of oil and change
if necessary.
3. Check drive belt tension and
tighten if necessary.
NOTE
Oil levels should be checked every 24 hours of operation.
Proper oil drain schedules require oil be changed before the contaminant load becomes so great that the
lubricating function of the oil is impaired or heavy disposition of suspended contaminants occurs. To check
the condition of the oil, drain a sampling into a clean container and check for the presence of water or solids.
Slight discoloration of the oil should not necessitate an oil change.
7.3 SPARE PARTS
Should adjustments or replacement eventually be needed, these can often be performed locally as
described in this book after obtaining required parts. Personnel should have a good background of
mechanical experience and be thoroughly familiar with the procedures outlined in this manual. Major
repairs not covered in this book should be referred to the nearest Tuthill Vacuum & Blower Systems service
representative.
When ordering parts, give all blower nameplate information, as well as the item number and parts description
as per the parts lists and assembly drawings for your particular model. Repair kits are available for all
models. These kits contain all of the seals, bearings, O-rings, locks, and special retaining screws necessary
for an overhaul. For your convenience when ordering parts, we suggest you complete the Operating Data
Form included on the inside, back cover of this manual.
In developing a stock of spare parts, consider the following:
• The degree of importance in maintaining the blower in a “ready” condition
• The time lag in parts procurement
• Cost
• Shelf life (seals and O-rings)
Contact Tuthill Vacuum & Blower Systems Service Department for any assistance in selecting spare parts.
