Cutting Fluid System
Magnesium fires are
extremely dangerous!
When cutting magnesium,
always use a cutting fluid
intended for this type of
metal and carefully follow
the fluid manufacturer's
recommendations.
This bandsaw has a built-in cutting fluid system
that extends the life of your bandsaw blades
by lowering the temperature of the blade and
workpiece and washing away chips.
To use the cutting fluid system:
1. Thoroughly clean and remove any foreign
material that may have fallen inside the
reservoir during shipping.
2. Place the filter screen and drain tube in the
reservoir as shown in Figure 34.

While simple in concept and function, many
issues must be taken into account to find and
use the correct cutting fluid. Always follow
all product warnings and contact the fluid
manufacturer for unanswered questions.
Use the information below as a guideline to
choose the appropriate cutting fluid. Always refer
to the cutting fluid manufacturer for specific
application and safety information:
• For cutting low alloy, low carbon, and
general-purpose category metals with a
bi-metal blade —use a water soluble cutting
fluid.
• For cutting stainless steels, high carbon, and
high alloy metals, brass, copper and mild
steels—use "Neat Cutting Oil" (commonly
undiluted mineral oils) that have extreme
pressure additives (EP additives).
• For cutting cast iron, cutting fluid is not
recommended.
Remember: Too much flow at the cutting fluid
nozzles will make a mess and can make the work
area unsafe; and not enough fluid at the cut will
heat the blade, causing the blade teeth to load up
and break.
Tip: Using a refractometer or hydrometer to
replenish water in water-based coolant can
extend the life of blades and coolant, and ensure
consistent cutting results.

HAzARD! Use proper personal
protection equipment when
handling cutting fluid and
follow federal, state, and fluid
manufacturer requirements
to properly dispose of cutting
fluid.
3. Fill the reservoir to the "high" mark with
your chosen cutting fluid solution.
