Changing Coolant
Tools Needed
Hex Wrench 4mm .............................................. 1
Catch Pan .......................................................... 1
Empty Bucket 5 Gal........................................... 1
Rubber Hose (optional) ..................................... 1
New Coolant ..........Approx. 2 Gallons (7.5 Liters)
To change the coolant:
1.
Put on personal protective equipment.
2.
Place the catch pan on the table, position
the coolant nozzle into the pan, then use the
coolant pump to drain the reservoir.
Note: When the catch pan is near full, empty
it into a 5 gallon bucket, then repeat the pro-
cess until the reservoir is empty.
Tip: Alternately, slide a rubber hose onto
the coolant nozzle and point it into 5 gallon
bucket.

DISCONNECT MACHINE FROM POWER!
4.
Clean away debris and grime from the cool-
ant return screen and the surrounding area,
then remove the screen from the base.
5.
Thoroughly clean out the reservoir. Make
sure the interior is completely dry before add-
ing new coolant.
Note: Use a shop vacuum and a cleaning
solution that is compatible with type of cool-
ant. For instance, if you are using a water-
base coolant, then use a water-base cleaning
solvent. Also, use magnets to remove any
metal chips left behind.
6.
When the reservoir is clean and dry, fill the
reservoir with new coolant through the hole
in the base left by the return screen.
Tip: Place a couple of magnets inside the
reservoir under the return screen to collect
metal particles and keep them out of the cool-
ant pump.
7.
Re-install the return screen before resuming
milling operations.

Machine Storage
Qty
The machine must be properly prepared if it will
be stored for any period of time. Doing this will
help prevent the development of rust and corro-
sion and ensure the mill remains in good condition
for later use.
Note: When taking the machine out of storage,
repeat the Test Run and the Spindle Break-In.
To prepare the machine for storage:
1.
DISCONNECT MACHINE FROM POWER!
2.
Lubricate the machine as directed in
Lubrication, beginning on Page 41.
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 in
place of rust preventative.
5.
Loosen belts to prevent them from stretch-
ing during storage. Post a reminder on the
machine that belts need to be re-installed or
tensioned before resuming operations.
6.
Place a few moisture-absorbing desiccant
packs inside the electrical cabinet.
7.
Cover and place the machine in a dry area
that is out of direct sunlight and away from
hazardous fumes, paint, solvents, or gas.
Fumes and sunlight can bleach or discolor
paint and plastic parts.
