The coolant system consists of a reservoir, pump,
and hoses with valves. The pump pulls coolant
from the tank and sends it to the valves, which
control the flow of coolant. As the coolant leaves
the work area, it drains through the machine base,
where the swarf and metal chips are screened
out, and back into the reservoir.

BIOLOGICAL & POISON
HAZARD!
Use correct personal
protection equipment
when handling coolant.
Follow federal, state,
and fluid manufacturer
requirements for proper
disposal.
Hazards
As coolant ages and gets used, dangerous
microbes can proliferate and create a biological
hazard. The risk of exposure to this hazard can
be greatly reduced by replacing the old coolant on
a monthly basis, or as indicated by the manufac-
turer of the cutting fluid.
When working with the coolant, minimize expo-
sure to your skin, eyes, and lungs by wearing
the proper PPE (Personal Protective Equipment),
such as long-sleeve waterproof gloves, protective
clothing, splash-resistant safety goggles, and a
NIOSH-approved respirator.
Although most swarf from machining operations is
screened out of the coolant before it returns to the
tank, small particles will accumulate in the bottom
of the reservoir in the form of sludge. To prevent
this sludge from being pulled into the pump and
damaging it, the pump’s intake is positioned
above the bottom of the tank. This works well
when the tank is regularly cleaned; however, if
excess sludge is allowed to accumulate, the pump
will inevitably begin sucking it up.

To add coolant:
1. DISCONNECT MACHINE FROM POWER!
2. Remove chip collection tray from machine
base (see
Figure 72) and clean chip collec-
tion tray.
3. Mix coolant according to cutting fluid manu-
facturer's specifications.
4. Fill reservoir with coolant until it is at the
maximum fill line shown in
Figure 73. Fill line
is just above top hex bolt that secures ther-
mometer to machine base.
5. Replace chip collection tray.
