MAINTENANCE
Keep your machine clean. At the end of each day, clean the machine. Wood contains moisture, meaning that
sawdust and wood chips can cause rust if not removed. Regular oil attracts dust and dirt. Teflon lubricant tends to
dry and has less of a tendency to accumulate dirt and saw dust. Periodically check that all nuts and bolts are tight.
The drive belt should last for many years depending on usage, but it needs to be inspected regularly for cracks,
cuts and general wear. If damage is found, replace the belt before operation.
All bearings are sealed for life and do not require any maintenance. If a bearing becomes faulty, replace it.
The lathe is made from steel and cast iron. All non-painted surfaces will rust if not protected. It is recommended
that they are protected by applying wax.
Blow out dust accumulation inside the motor, the housing, and the bed assembly frequently. If the tailstock has
been used as a guide for drilling through the center of a workpiece, also blow sawdust or shavings out of the center
of both the headstock spindle and the tailstock quill.
A coat of machine lubricant applied to the bed will help keep the surface clean and the movement of the tool rest
and tailstock smooth.
Periodic lubrication of the spring levers and other threaded parts will make these parts easier to operate.
