Changing Oil & Flushing Reservoir
Small metal particles may accumulate at the bot-
tom of the reservoir with normal use. Therefore, to
keep the reservoir clean, drain and flush it at least
once a year.
Place a catch pan under the apron drain plug
shown in Figure 133, remove the fill plug, then
use a 6mm hex wrench to remove the drain plug
and empty the reservoir.
Drain Plug

Flush the reservoir by pouring a small amount of
clean oil into the fill hole and allowing it to drain
out the bottom. Replace the drain plug, add oil as
previously described, then re-install the fill plug.

Bedways
Oil Type .... Grizzly T23962 or ISO 68 Equivalent
Oil Amount ......................................... As Needed
Lubrication Frequency ................................. Daily
Before lubricating the bedways (see Figure 134),
clean them with mineral spirits. Apply a thin coat
of oil along the length of the bedway. Move the
steady rest, carriage, and tailstock to access the
entire length of the bedways. If the lathe is in a
moist or dirty environment, increase the lubrica-
tion interval.

Longitudinal Leadscrew
Oil Type .... Grizzly T23962 or ISO 68 Equivalent
Oil Amount ......................................... As Needed
Lubrication Frequency ................................. Daily
Before lubricating the leadscrew (see Figure
134), clean it first with mineral spirits. A stiff 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 a thin coat of oil along the length of the
leadscrew. Use a stiff brush to make sure the oil
is applied evenly and down into the threads.
Note: In some environments, abrasive material
can become caught in the leadscrew lubricant and
drawn into the half nut. In this case, lubricate the
leadscrew with a quality dry lubricant.
