Coolant Service
Hazards
As coolant ages and gets used, dangerous
microbes can proliferate and create a biological
hazard. Minimize risk of exposure to this hazard
by replacing the old fluid on a monthly basis, or
as indicated by the fluid manufacturer.
Remember, when working with coolant you
MUST minimize exposure to your skin, eyes, and
lungs by wearing the proper PPE, such as splash-
resistant safety goggles, long-sleeve, waterproof
gloves, protective clothing, and a NIOSH—
approved respirator.
BIOLOGICAL & POISON
HAZARD!
Use the correct personal
protection equipment when
handling coolant. Follow
federal, state, and fluid
manufacturer requirements
for proper disposal.
The coolant system consists of an integral coolant
reservoir (part of lathe base), pump, and flexible
nozzle. The pump pulls fluid from the reservoir
and sends it to the valve (see Figure 73), which
controls the flow of coolant to the nozzle. As the
fluid leaves the cutting area, it drains back into
the tank through the catch tray and chip screen
shown in Figure 74.

Coolant Replacement
Although most swarf from machining operations
is screened out of coolant before it returns to
the tank, small particles will accumulate at the
bottom of the tank as sludge.
To prevent the sludge from being pulled into the
pump and damaging it, the pump’s suction tube
is positioned a couple inches from the bottom of
the reservoir and fitted with a fine screen. This
design works well when the tank is regularly
cleaned; however, if too much sludge is allowed to
accumulate before the tank is cleaned, the pump
will inevitably begin recirculating the sludge and
become damaged. Change coolant annually or
according to fluid manufacturer.
To change coolant:
1.
DISCONNECT LATHE FROM POWER!
2.
Put on PPE.
3.
Clean chip screen, wipe out lathe chip tray,
and remove reservoir access plate shown in
Figure 74.

4.
Pump out old coolant into sealable 5-gallon
buckets.
5.
Remove reservoir access plate shown in
