Maintenance
Vacuum Pump
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use Tuthill
Pneulube Blower Lubricant in the gear end of the
vacuum pump for all operating temperatures. Tuthill
Pneulube is formulated especially for positive displace-
ment blower service to provide maximum blower
protection at any temperature. One filling of Tuthill
Pneulube will last a many times longer than a premium
mineral oil.
NOTE: Tuthill Pneulube (Part# 86318420) is the oil in
the vacuum pump. Topping off or adding petroleum
oil to synthetic oil is NOT recommended.
1. Check the oil level daily to assure the proper level.
PROPER LEVEL cannot be overemphasized. Too
little oil will ruin bearings and gears. Too much oil
will cause overheating. Use the illustration as a
guide when adding oil.
2. To prevent rust from building up inside the vacuum
pump (if moisture exists) we have provided a lubri-
cation cup on the front of the unit.
First run the unit at least 1 minute to remove any
moisture from the vacuum pump. Next, fill the
lubrication cup with water displacing lubricant, for
5 seconds while the unit is running and the vac-
uum inlets are sealed. Do this at the end of each
working day.
3. Drain, flush and replace oil every 1500 hours or
yearly, whichever comes first. Change oil more
frequently if inspection so indicates. With Tuthill
Pneulube, perform the oil change maintenance
every 4500 hours or every 2 years, whichever
comes first.
Oil capacity is approximately 3.4 ounces in gear end.
4. Vacuum pump lubrication is vital to performance of
our pump. Failure to follow the maintenance
schedule in the “Maintenance Schedule” can lead
to permanent damage to your blower.
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
5. Bearings on the drive end of the blower require
grease lubrication every 250 hours of operation.
