LUBRICATION
Every M-D Pneumatics™ blower from Tuthill Vacuum & Blower Systems is factory tested, oil drained and shipped dry to its
installation point. Both independent oil reservoirs must be filled to the proper level before operation.
Shaft bearings at the gear end of the blower are splash lubricated by one or both gears dipping into an oil reservoir formed in the
gear end plate and cover. Shaft bearings at the drive end of the blower are lubricated by a slinger assembly dipping into an oil
reservoir. Before starting the blower, fill oil sumps as shown below under “Filling Procedure.” Tuthill Vacuum & Blower Systems
approved mineral-based, synthetic and food grade lubricants are listed on page 15.
FILLING PROCEDURE
1. Shut off and lock out power to the blower drive motor.
2. Remove fill plugs or breathers from both gear end and drive end plates.
3. SLOWLY pour oil through fill until oil appears in the oil sight glass. Bring oil level to center of sight glass.
4. Verify oil level is at proper level in BOTH gear end and drive end sight glasses.
5. Replace fill plugs or breathers that were removed in step 1.
CAUTION: Do not start the blower until you are sure oil has been put in the gear housing. Operation of the blower without
proper lubrication will cause the blower to fail and void its warranty.
WARNING: NEVER ATTEMPT TO CHANGE OIL WHILE THE BLOWER IS IN OPERATION. Failure to heed this warning could
result in damage to the equipment and/or serious personal injury. Oil level must ONLY be checked while the
blower is not running, and the power locked out.

FLOW CONFIGURATIONS
17 series EQUALIZER
®
blowers are shipped from the factory in a
horizontal flow configuration. Bottom drive with horizontal flow
is only available on 4500 EQUALIZER DF models.
46 series EQUALIZER blowers are shipped from the factory in
either left drive or right drive, vertical flow configuration.
If flow direction is changed, the oil level sight glasses and
breathers must be relocated to proper positions, as shown to the
right.
Failure to change plug location will result in blower failure and
void the product warranty.
SPECIAL NOTE REGARDING
4600 & 6000 EQUALIZER RM MODELS:
Vertical flow 4600 & 6000 EQUALIZER RM models with either
left or right drive can be converted to top drive. However, a
left drive blower cannot be converted to right drive, and vice
versa.
Top drive 4600 & 6000 EQUALIZER RM models can be
converted to left drive only. Either left or right drive blowers
can be converted to top drive. Unless specifically stated by
factory, never arrange the blower so that the flow direction is
horizontal with bottom drive. This will result in blower failure
and void the product warranty.

* Oil capacities are based on filling from dry condition. Less oil may be needed depending on emptiness of oil reservoirs after
draining. Always fill the oil sumps until oil level is in the center of the sight glass in EACH END of the blower. Following this
procedure will insure proper oil level.
