9.0 User-maintenance
Disconnect machine from
power supply before performing any
maintenance. Failure to comply may cause
serious injury.
Change hydraulic oil and filter after first 3,000 hours
of operation. Then change after every 5,000 hours
of operation. Follow local regulations for disposal of
used oil.
Keep table and T-slots clean and free of rust.
Periodically apply a light coat of SAE30 oil or
equivalent to exposed metal surfaces, such as
table, fences and blades.
Keep blade area free of deposits or shavings, which
can impede cut quality and hasten blade wear.
If blades become dull, they can be removed and re-
sharpened.
9.1 Additional servicing
Any additional servicing should be performed by an
authorized JET service center.
