WARNING

Use lock out/tag out procedures to disable the electrical energy source

before any service or work is done on the booster.

WARNING

Avoid extended exposure in close proximity to machinery with high intensity

noise levels. Wear adequate ear protection.

NOTE

Use proper care and good procedures in handling, lifting, installing,

operating, and maintaining the equipment.

5.3 LUBRICATION

Every booster from Tuthill Springfield is factory tested; oil drained and shipped dry to its installation point.

Both oil reservoirs must be filled to the proper level before operation. In addition to the splash lubrication,

booster series incorporating pressure lubrication with a integral oil pump, pressure relief valve, filter and

oil-to-coolant heat exchanger. Before starting the booster, fill oil sumps as shown below within the

Filling

Procedure

section. Tuthill Springfield approved mineral-based, synthetic and food grade lubricants are

listed on page 32.

Select a suitable low vapor pressure lubrication for high vacuum service such as Tuthill Pneulube Synthetic

oil. For higher pressure, 1 torr or more, a good grade of turbine lubricating oil may be used. It should have

a viscosity of approximately ISO 100 @ 100°F (38°C). Also refer to the Recommended Lubricants page

within this manual.

Add vacuum oil to the blower in the quantity shown within the Specifications Table. The oil level must be

maintained within the notched area of the sight glass. Lower drive units have “bull’s eye” type oil level

gauges. Maintain oil levels at the center of the glass.

WARNING

Never attempt to change or add lubrication while the booster is running.

Failure to heed this warning could result in damage to the equipment or

personal injury.

WARNING

Properly dispose of the spent lubricants. Refer to the manufacturer of the

lubricant and any regulations to assure proper and safe disposal.

WARNING

Do not start the booster until you are sure oil has been put in the gear

housing and rear cover. Operation of the booster without proper lubrication

will cause the booster to fail and void the warranty.

NOTE

Refer to Table 1 for oil capacities.
