11.1 Lubrication
See sect. 11.3, 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.
11.1.1 Gear box
Drain and refill gear box according to Table 3
recommendations.
To check gear box oil level, place bow in down
position and wait a few moments for oil to settle.
Check level in sight glass on side of gear casing.
Correct level is dot in middle of sight glass.
To change gear box oil:
1. Connect machine to power and raise bow to
highest position.
2. Unscrew and remove drain plug (Figure 11-2),
and allow lubricant to drain completely. Follow
local regulations for proper disposal of used oil.

3. Reinstall drain plug.
4. Remove fill plug at opposite side of gear case
(next to sight glass) and insert approximately
850 mL (1/4 gal.) of
Mobil
®
SHC Gear Oil 460, or
equivalent, until level reaches dot in middle of
sight glass.
5. Reinstall fill plug.
6. Lower bow. Recheck sight glass, top off if
needed.
11.1.2 Servicing hydraulic oil
1. Disconnect machine from power source.
2. Remove hydraulic reservoir access panel.
3. Check oil level (A, Figure 11-3). If level is below
yellow (upper) line, the reservoir should be
filled.
4. Disconnect electrical power.
5. Remove reservoir fill cap (B).
6. Add oil up to yellow (upper) line. Install fill cap.
7. If a significant amount of oil must be added,
check for oil leaks in pump components, lines,
and hydraulic cylinder. Correct source of
leakage before operating saw.
8. Connect electrical power. Raise and lower bow
to confirm that saw is operating correctly.

11.1.3 Servicing cutting fluid
Pour cutting fluid or 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 cutting fluid, use drain plug located on left
side of machine base, near pump access panel.
Follow local regulations when disposing of used
machine fluids.
