<br />
<div style="text-align: justify;"><span style="font-size: large;"><span style="font-size: small;"> Grease is widely used in lubricating the anti friction bearing. The standard grease recommended by Mitsubishi Electric is SHELL DRUM R grease which is superior in lubrication, lubricating life, water and heat resistivity. The anti-friction bearing is supplied with required amount of grease at the time of motor assembly in the shop, but grease is to be again added at the time of the trial run at the site or after the motor has been left un-operated for more than two months.</span></span></div><span style="font-size: large;"><br />

<div style="background-color: yellow; color: red; text-align: center;"><span style="font-size: large;">Caution</span></div><br />
<div style="text-align: justify;"><span style="font-size: large;"><span style="font-size: small;">Only SHELL DRUM R is to be used. If different grease is mixed, a chemical change occurs and the lubricating capacity is greatly decreased </span></span></div><br />
<div style="text-align: center;"><span style="font-size: large;"><span style="background-color: yellow; color: red;"> Supply Of Grease  </span></span></div><br />
<div style="text-align: justify;"><span style="font-size: large;"><span style="font-size: small;">The lubricating capability of the originally-supplied grease decreases as the motor is operated for a certain period of time. Therefore, more grease should be supplied depending on the bearing size and motor revolution after the motor has been operated for a certain period of time. Plate indicating the supply amount of grease fitted at the motor frame. </span></span></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;"><span style="font-size: small;">Grease is to be supplied by means of a grease gun, and grease nipple is to be cleaned before using the gun. (Fig. 1-4)<br />
be sure to supply grease while the motor is in operation</span></div><div style="text-align: justify;"><br />
