Coolant

Hazards

As some coolant ages, 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 regular basis, as
indicated in the maintenance schedule.
The important thing to keep in mind when working
with the coolant is to minimize exposure to your
skin, eyes, and respiratory system by wearing
the proper PPE (personal protective equipment),
such as splash-resistant safety glasses, long-
sleeve gloves, protective clothing, and a NIOSH
approved respirator.
BIOLOGICAL & POISON
Use the correct personal
protection equipment when
handling coolant. Follow
federal, state, and fluid
manufacturer requirements
for proper disposal.
A small amount of coolant is lost during normal
operation. Check the coolant reservoir regularly
and fill it if necessary. We recommend chang-
ing the coolant every three months or sooner if it
develops an unpleasant odor. However, be sure
to follow the coolant manufacturer's instructions
when checking, adding, or changing coolant.
The coolant reservoir holds approximately 2 gal-
lons (7.5 liters) of fluid.
Running the coolant pump without ade-
quate coolant in the reservoir may perma-
nently damage the coolant pump, which will
not covered by the warranty.

3.
Use a clean metal tool as a dip stick to mea-
sure the level of coolant in the reservoir. If
the level is lower than 1
pouring it through the hole in the base left by
the return screen.
4.
Re-install the return screen before resuming
milling operations.
Tip: As an alternate method, leave the return
screen in place and use a clean, small instru-
ment through the holes in the return screen
as a dip stick. If more coolant is necessary,
make sure the screen and surrounding area
are clean from any containments, then add
the coolant through the screen.
