necessary.
5) For lubricating points, oil brands and appropriate levels, see the various
instruction plates.
6) Switches and levers should operate smoothly.
7) Check the coolant level, and add coolant, if necessary.
8) When switching the machine on, connect the factory feeder switch to the

1.4.2 Routine inspections

WARNING
When checking belt tensions, do not get your fingers caught between the belt
and pulley.
CAUTION
1) Check pressure gages for proper readings.
2) Check motor, gearboxes and other parts for abnormal noises.
3) Check the motor lubrication, and sliding parts for evidence of proper
lubrication
4) Check safety covers and safety devices for proper operation
5) Check belt tensions. Replace any set of belts that has become stretched with
a fresh matching set.

1.4.3 Warm up

1) Warm up machine, especially the spindle and feed shaft by running them for
10 to 20 minutes at about half or one-third the maximum speed in the
automatic operation mode.
2) This automatic operation program should cause each machine component to
operate. At the same time check their operations.
3) Be particularly careful to warm up the spindle, which can turn up to 3500RPM.
If the machine is used for actual machining immediately after being started;
following a long idle period, sliding parts may be worm due to lack of oil. Also,
thermal expansion of the machine components can jeopardize machining
accuracy. To prevent this condition, always warm the machine up.
