Model T28366 (Mfd. Since 04/18)
Using Coolant
System
The Model T28366 has a built-in coolant
system that can extend the life of your blades by
preventing them from overheating.
Use only water soluble coolants, such as H9240
Heavy-Duty Soluble Oil (see
Figure 41 on
Page 29), with the Model T28366. This
chlorinated, general purpose coolant contains
extreme pressure additives (EP additives) to
provide excellent tool life. It can be used on all
metals except titanium.
The coolant system (see
Figure 22) consists of a
coolant reservoir, pump, and hose with a control
valve. The pump pulls fluid from the reservoir and
sends it to the valve, which controls the flow of
coolant. As the fluid leaves the work area, it drains
back into the reservoir through the tray screen,
where the swarf and metal chips are filtered out.
To use coolant system:
1. Add coolant to coolant reservoir (refer
to
Coolant System on Page 30 for
instructions).
Note: Coolant is not recommended for
cutting cast iron.
2. Turn master power switch to "1" (ON)
position and press start button on lever arm
(see
Figure 23).
FIRE HAZARD! DO NOT
cut magnesium when using
oil-water solutions as
coolant! Water in the
solution could cause a
magnesium-chip fire.

3. Slowly turn coolant flow control valve to open
position (see
Figure 22). Coolant should
begin flowing onto blade.
Note: Starting machine with coolant flow
control valve fully open will make a mess
and can make the work area unsafe due to a
slipping hazard on floor.
