Coolant System Service - Grizzly G0812 Owner's Manual

Coolant System
Service
The coolant system consists of a fluid tank, pump,
and hose with valves. The pump pulls fluid from
the tank and sends it to the valves, which control
the flow of coolant. As the fluid leaves the work
area, it drains through the cabinet, where the
swarf and metal chips are screened out, and back
into the tank.
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 tank in the form of sludge. To prevent this
sludge from being pulled into the pump and dam-
aging 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.
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 fluid on a
monthly basis, or as indicated by the fluid manu-
facturer.
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.
BIOLOGICAL & POISON
Use correct personal
protection
when handling coolant.
Follow federal, state,
and fluid manufacturer
requirements for proper
disposal.
