To change coolant:
1. Put on personal protective equipment.
2. Place catch pan on table, position coolant
nozzle into pan, then use coolant pump to
drain reservoir.
Note: When catch pan is near full, empty it
into a 5 gallon bucket, then repeat process
until reservoir is empty.
Tip: Alternately, slide a rubber hose onto
coolant nozzle and point it 5 gallon bucket.
3. DISCONNECT MACHINE FROM POWER!
4. Clean away debris from coolant return screen
and surrounding area, then remove screen
from base.
5. Thoroughly clean out reservoir. Make sure
interior is dry before adding 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 reservoir is clean and dry, fill reservoir
with new coolant through hole in the base left
by return screen.
Tip: Place a couple of magnets inside res-
ervoir under return screen to collect metal
particles and keep them out of coolant pump.
7. Re-install return screen before resuming mill-
ing operations.
V-Belt Service
During the first 16 hours of use, the V-belts may
stretch slightly and seat into the pulleys. It is impor-
tant to check and adjust them to compensate for
this initial wear. Check the tension thereafter on a
regular basis. If belts become excessively worn or
damaged, replace them.
All V-belts can be replaced by releasing the ten-
sion and rolling them off the pulleys, then rolling
the new belts back onto the pulleys.
