and grease type.
4.1.5. Other Points to note
a.
Make sure the transmission system, including belts, screws, bolts, nuts and
set pins are in good condition.
b.
Dismantle all locks which fasten the moveable parts of the motor during
transportation, and turn the shaft by hand (if practical) to check if it moves
freely.
c.
Check if there is any evidence of foreign matter inside the motor before
starting.
d.
Make sure the items above are examined. Test the motor with or without
load. Record and check according to “Maintenance” at 15 minute intervals
during the first three hours of operation. Then conduct regular examinations
after longer intervals. If problems are experienced test without load to
ascertain whether it is a load, structure, alignment or motor issue.
4.2.
STARTING OPERATION.
4.2.1.
Starting Load.
The initial test involves running the motor without load. Unless specified, a
motor is designed to start with light load, which is then gradually increased
to full load, as the motor accelerates to full speed.
4.2.2.
Starting.
The bearings are initially lubricated with the correct grade of grease at
the factory. After installation, long storage and at initial start
up/commissioning the bearings must be fully purged with new grease.
Please refer to section 7.
