MAINTENANCE
VACUUM PUMP
Refer to the Vacuum Pump Operation and Service
Manual (P/N 86036610, PRV NO. 67-945307) for
specific instructions.
Lubrication: We recommend that you use AEON
PD Synthetic Blower Lubricant in the gear end of the
vacuum pump for all operating temperatures. AEON
PD is formulated especially for positive displacement
blower service to provide maximum blower
protection at any temperature. One filling of AEON
PD will last a many times longer than a premium
mineral oil.
NOTE: AEON PD (Part# 86189090, PRV NO.
05-008039) 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 lubrication 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 WD-40, or a similar
lubricant, for 5 seconds while the unit is running
and the vacuum inlets are sealed. Do this at the
end of each working day.
