To change the coolant:
1. Put on personal protective equipment.
2. Place catch pan on table, position the coolant
nozzle into pan, then use coolant pump to
drain reservoir.
Note: When catch pan is near full, empty it
into 5 gallon bucket, then repeat process.
Tip: Alternately, slide a rubber hose onto
coolant nozzle and point it into 5 gallon buck-
et.
3. DISCONNECT MILL FROM POWER!
4. Remove coolant reservoir access panel from
the rear of column.
5. Remove the two pump mounting cap screws
and move pump out of the way.
6. Thoroughly clean out bottom of the reservoir
and the base of pump. Make sure interior is
completely dry before adding new coolant.
Note: Use a cleaning solution that is compat-
ible with type of coolant. For instance, if you
are using a water-base coolant, then use a
water-base cleaning solvent.
7. When reservoir and pump are clean and dry,
replace the pump, and access panel.
Tip: Place a couple of magnets inside res-
ervoir under return screens to collect metal
particles to keep them out of coolant pump.
8. Clean away debris and grime from coolant
drain screen on base of mill, then pour cool-
ant through one of the screens to fill reser-
voir.
Machine Storage
The mill must be properly prepared if it will be
stored for any period of time. Doing this will help
prevent the development of rust and corrosion
and ensure the mill remains in good condition for
later use.
Note: When taking the mill out of storage, repeat
the
Test Run and the Spindle Break-In.
To prepare the mill for storage:
1. DISCONNECT MILL FROM POWER!
2. Lubricate mill as directed in Lubrication
beginning on
Page 45.
3. Clean out coolant reservoir as directed in
Changing Coolant on this page.
4. Thoroughly clean all unpainted, bare metal
surfaces, then coat them with quality rust pre-
ventative. Take care to ensure these surfaces
are completely covered but rust preventative
is kept off painted surfaces.
Note: If the machine will be out of service
for only a short period of time, use way oil or
a good grade of medium-weight machine oil
(not auto engine oil) in place of rust preventa-
tive.
5. Loosen belts to prevent them from stretching
during storage. Post a reminder on mill that
belts need to be re-installed or tensioned
before resuming operations.
6. Place a few moisture-absorbing desiccant
packs inside electrical cabinet.
7. Cover and place machine in a dry area that
is out of direct sunlight and away from haz-
ardous fumes, paint, solvents, or gas. Fumes
and sunlight can bleach or discolor paint and
plastic parts.
8. At least once a month, start mill and run all
gear-driven components for a few minutes.
This will keep bearings, bushings, gears, and
shafts well lubricated and protected from cor-
rosion.
