1. SCOPE
To give recommended guidelines for electric motor relubrication.
2. START UP

if a motor has been stored for a period of six months or more, it should be lubricated prior
to starting (See Fig. 1) using a standard hand held grease gun.

It should be noted that grease leakage around the shaft hole could indicated over-
packing. Excess grease should be purged out by operating the motor temporarily with
the relief open.
Lubrication of electric motors should be done as a part of a planned maintenance
program.
Before greasing, be sure fittings are clean and free from dirt. Always relubricate using
grease that is fresh and free from contamination.
Toshiba motors may be equipped with an automatic grease relief fitting, grease plug or
grease cover plate for the outlet.
It should be noted that it may be necessary to remove an automatic type fitting due to
hardening of grease. Motors utilizing a grease plate may require the scraping out of old
grease a minimum of once every two years.
3. STANDARD SERVICE
1. Select the proper service condition from Fig. 2.
2. Select the frequency and volume from Fig. 3.
