MAINTENANCE
Ways & Slides
The way pump shown in Figure 117 lubricates
the saddle and cross slide way guides with the oil
from the apron reservoir.
To use the way pump to lubricate the ways, pull
the pump knob out for two or three seconds and
then push it in. The pump draws oil from the
apron reservoir and then forces it through drilled
passages to the way guides.
Repeat this process and move the carriage left/
right and the cross slide forward/backward to
distribute oil along the way guides.
Lubricate the guides once before and once after
operating the lathe. If the lathe is in a moist
or dirty environment, increase the lubrication
interval and make sure to keep the oil level full.

Lubrication Frequency ...................................Daily
Before lubricating the leadscrew (Figure 116),
clean it first with mineral spirits. A paint brush
works well to help clean out the threads. Make
sure to move the carriage out of the way, so you
can clean the entire length of the leadscrew.
Apply oil along the length of the leadscrew. Use
a paint brush to make sure the oil is evenly
applied and down in the threads.

Checking & Adding Oil
To check the oil level, remove the fill plug and
look inside the reservoir (Figure 116). The oil
level must remain full to keep the leadscrew
bearing adequately lubricated. Pour oil in the
reservoir until it is as full as possible without
overflowing.

Unpainted & Machined Surfaces
Besides the ways and leadscrew, all other
unpainted and machined surfaces should be
wiped down daily to keep them rust-free and in
top condition. This includes the top of the saddle,
the cross slide, compound slide, tool post, chuck,
feedrod, and any other surface you can find that
could be vulnerable to rust if left unprotected
(this especially includes any parts that may be
exposed to water soluble cutting fluids). Typically
with these parts, a thin film of oil is all that
is necessary for protection. Any quality metal
protectant can be used to protect machined
surfaces, including either of the oils you use
elsewhere in the lathe.
