G0641 Double Miter Saw

Lubrication
For the many moving parts of the Model G0641,
there are three lubrication systems: 1) the pneu
-
matic oiler attached to the air regulator-lubricator,
2) the lower pivot arm automatic oil system, and
3) manual lubrication of the arbor housings and
remaining pivot points.
The pneumatic oiler injects lubrication into the air
system as it is used to keep the main and hold-
down pneumatic rams moving smoothly.
To lubricate the pneumatic system:
1. DISCONNECT SAW FROM AIR SUPPLY!
2. Fill the oil reservoir with ISO-VG32 tool oil
(see Figure 34).

3. Tighten the flow adjustment screw clockwise
until it stops, then open it
1
⁄2 turn.
Note: The goal is to inject enough lubrication
into the air system to keep a very light coat of
oil on the surface of the rams during opera
-
tion.
2. Turn the flow adjustment screw counterclock-
wise to increase the flow rate of lubricant.
3. Flip the valve lever up, as shown in Figure
35, to start the flow of lubricant from the bot-
tom of the reservoir into the oil line.
Note: We recommend a setting of one drop
per 20 pivot arm cycles. Have an assistant
count the drops while you cycle the blades
lowering and raising to reach this setting.
4. Flip the valve levers down to close off the
flow of lubricant when the machine is not in
use.

NOTICE
Failure to perform proper lubrication main-
tenance on this machine will lead to prema

ture wear of the moving parts, and will void
the warranty.
lubrication
The lower pivot arm oil system is adjusted so that
an adequate flow of lubricant moves through the
oil lines to the sides of the lower pivot arms.
To lubricate the lower pivot arms:
1. Slide the fill plate aside to add ISO-VG32 tool
oil to the reservoir (see Figure 35).
