11.0 Maintenance
Before doing maintenance on
the lathe, disconnect it from the electrical
supply by pulling out the plug or switching off
the main switch. Failure to comply may cause
serious injury.
11.1 General procedures
Maintenance on the lathe should be performed at
periodic intervals to ensure that the machine is in
proper working order, that all fasteners are tight,
and all necessary adjustments have been made.
Inspection and maintenance should be performed
at least twice a year, but more frequently if the
lathe receives constant use.
Clean and oil the lathe bed so that headstock,
tailstock and tool rest base will slide easily. Clean
any rust spots that may develop on the bed with a
commercial rust remover.
Use compressed air to blow out the interior of the
headstock, in order to keep sawdust and chips
from accumulating on belts and sheaves. Also blow
off debris that accumulates in the motor fan.
Frequently clean out the morse tapers on both
headstock and tailstock. Commercially available
taper cleaners may be acquired from tool stores.
Bearings are permanently lubricated and sealed,
and do not require further lubrication.
11.2 Pulley lubrication
After every 200 working hours, or every 30 days,
use a grease gun to insert a good quality, all-
purpose grease into the zerk fitting on the motor
shaft (Figure 32) and the groove of the main
spindle (Figure 33).

11.3 Belt and bearings replacement
Changing belt and bearings can be a difficult task,
and should be performed by a JET authorized
service center. Remove headstock and take it to a
service center for servicing.
