4. Change Gea r Axle – Periodically remove end
plug (J, Figure 9) and press #2 lithium grease
into the axle to lubricate the gear axle and
sleeve. Coat all gears with non-slinging
grease.
5. Gearbox – Oil must be up to indicator mark in
oil sight glass (D, Figure 8). Top off with SAE
20W oil. To add oil to the gearbox, pour it into
the pan (E, Figure 9). To drain, remove drain
plug (F, Figure 9). Drain oil completely and
refill after the first three months of operation.
Then change oil in the gearbox every six
months.
6. Apron – Oil must be between indicator marks
in the oil sight glass (G, Figure 11). Top off
with SAE 20W oil. Unscrew oil plug (H, Figure
11) to fill. To drain, remove drain plug on the
underside of apron. Drain oil completely and
refill after the first three months of operation.
Then, change oil in the apron annually.

7. One-shot Lube System: Pull knob (I, Figure 11)
and hold for several seconds to allow oil to fill
the pump from the apron reservoir. Then
release the knob which will push the oil
through various oil lines to lubricate the ways
below the saddle. Perform this several times
daily.
8. Threading Dial – Frequently lubricate via one
ball oiler (P, Figure 11) on top of the dial with
SAE 20W oil.
9. Cross Slide – Daily lubricate one ball oiler on
the handwheel housing (L, Figure 11)and three
ball oilers on the platform (K, Figure 12), with
SAE 20W oil.
