MAINTENANCE
Lubrication
Before operating the metal lathe, check the oil level and lubricate all sliding surfaces
such as the bed, half-nut, worm gear, leadscrew, feed rod, handle rod, tailstock quill
before and after operating. For best performance, do not leave metal chips and
coolant fluid on the bed, wipe down and oil the lathe after use.
Carriage, cross slide and top slide
The carriage oil level should be checked regularly. Change carriage oil after the first
3 months and once every year after. The carriage oil drain plug is found under the
carriage, drain oil. Reinstall drain plug. The carriage is filled with 1.2 Litres of SAE-30
motor oil through the filling plug (A) Fig.32 on the top of the carriage. Fill oil until it
reaches the 3/4 mark on the oil level indicator (B). Lubricate the ball oilers (C) with
regular machine oil, most are shown in Fig.32.
To lubricate the carriage and the cross slide way guides, pull the pump knob (D)
Fig.32 out and hold it for a few seconds, the pump will draw oil from the carriage
resevoir, then push pump knob in to pump oil through drilled passages in the way
guides. Repeat until properly lubricated.
Drive gears, headstock and gearbox
Lubricate the change gears (A) Fig.33 with thick bearing grease once a month.
After running for the first 3 months, change headstock oil. Change oil once a year
after first initial oil change. To drain oil from the headstock, remove left end cover,
remove oil drain bolt (B) Fig.33 and drain oil. Reinstall drain bolt. Open the top oil plug
(C) and fill with 8 Litres of EP68 hydraulic oil until it reaches the 3/4 mark on the oil
level indicator (A) Fig.34.
To drain oil from the gearbox, remove left end cover, remove oil drain bolt (D) Fig.33
and drain oil. Reinstall drain bolt. Remove oil fill bolt (E) and fill 1.3 Litres of SAE-30
motor oil until it reaches the 3/4 mark on the oil level indicator (B) Fig.34.
Tailstock
Lubricate the tailstock ball oilers (A) Fig.35 with regular machine oil. Oil the tailstock
quill (B) weekly with regular machine oil. It is recommended to remove the tailstock
monthly to wipe down the bed ways and relubricate.
Leadscrew, Feed Rod, Switch Control Rod, Rack and Guide ways
Make sure to lubricate the leadscrew (A) Fig.36, feed rod (B) and switch control rod
(C) with machine oil. Appply machine oil to the racks (D) and guide ways (E). Make
sure they are clean before lubricating. Lubricate the ball oilers (F) with regular
machine oil.
