10.1 Lubrication
See sect. 10.3, Table 3, for lubrication chart.
All ball bearings are permanently lubricated and
sealed. They require no further attention.
Use a light machine oil to lubricate moving parts as
needed.
Periodically apply light coat of machine oil to
exposed metal surfaces, such as vise bed, to
prohibit rust.
10.1.1 Gear box
Drain and refill gear box according to Table 3
recommendations.
Use sight glass (A, Figure 11-2) to check oil level.
To change gear box oil:
1.
Connect machine to power and raise bow to a
convenient position. Press E-stop.
2.
Unscrew and remove drain plug beneath gear
box, and allow lubricant to drain completely.
Follow local regulations for proper disposal of
used oil.

Reinstall drain plug.
4.
Remove fill plug (B) and insert approximately 2L
(1/2 gal.) of
Mobil
equivalent, until oil fills the sight glass.
5.
Reinstall fill plug.
10.1.2 Servicing hydraulic oil
1.
Disconnect machine from power source.
2.
Remove hydraulic tank access panel.
3.

Filling and Draining
Pour coolant mixture into chip tray so that it drains
through strainer into basin. The sight glass is
located on front of base.
Numerous cutting fluids on the market are
formulated for special applications. Consult your
local distributor for details if you have a long range
production task or are required to cut more exotic
materials. Refer to the cutting fluid provider's
instructions for mixing recommendations and fluid
life span.
To drain coolant, use drain plug located on front of
machine stand. Follow local regulations when
disposing of used machine fluids. Apply thread
sealing tape to the drain plug before re-installing.
Keep the overflow hole on right side of base, clean
and unobstructed.
Different brands of coolant may not mix properly. If
changing to new brand, first flush coolant line and
sump with an industrial degreaser or cleaner that
does not contain silicone or petroleum based
ingredients.
