PELLERIN MILNOR CORPORATION
3.1.4. Lubricant Identification and Procedures
Table 10 identifies the lubricant for each lubricant code given in the maintenance summary. Get
these or equivalent lubricants from from your local lubricant supplier.
When you add grease, always use the procedures given in Section 3.1.4.1. When you add grease
to motors, also use the procedures given in Section 3.1.4.2.
CAUTION 28 : Risk of damage—Bad lubricant will decrease the life of components.
• Make sure that all equipment and fittings used to apply lubricants are clean.
• Use only the given lubricants or equivalent lubricants that have the same specifications.

3.1.4.1. Grease Gun Procedures
CAUTION 29 : Risk of damage—Hydraulic pressure can push out seals and push grease into
unwanted areas (example: motor windings).
• Use a hand grease gun. A power grease gun gives too much pressure.
• Know the quantity of grease your grease gun gives each cycle (each stroke).
• Operate the grease gun slowly (10 to 12 seconds for one cycle).
• Add only the specified quantity. Stop if new grease come out of a drain port or other
opening.
• Remove spilled grease from belts and pulleys.
The tables give grease quantities in fluid ounces (fl oz) and milliliters (mL). You can also use
grease gun cycles (strokes). A cycle is each time that you pull the trigger. One cycle is usually
approximately 0.06 fl oz (1.8 mL). Your grease gun can give more or less than this. Measure the
output of your grease gun as follows:
1. Make sure that the grease gun operates correctly.
2. Operate the grease gun to put grease into a small container with fluid ounce or milliliter
increments. Pull the trigger fully and slowly.
3. Add a sufficient quantity of grease to measure accurately. Count the number of cycles of the
grease gun (the number of times that you pull the trigger).
4. Calculate the quantity for each cycle of the grease gun.
Example: 2 fl oz / 64 cycles = 0.031 fl oz for each cycle
Example: 59 mL / 64 cycles = 0.92 mL for each cycle
