Maintenance
V-Belts
After the first 20 hours of operation it is
necessary to check the tension on of the V-
belts. To do this, open the access door (A,
Figure 19). With medium finger pressure the
belt should push in approximately ½” about
midway between the pulleys. If there is too
much play, remove the three belt cover bolts
(B, Figure 19) and pull the guard off. Adjust
the tension by loosening the bottom jam nut
on the bracket (A, Figure 20) and then turn
down the top nut until the desired tension is
achieved.
Lubrication
Periodically apply a light grease to the tables
up/down lead screw. As well, apply a light oil
to the dovetail ways from time to time to allow
ease of movement.
The cutterhead bearings are permanently
greased for life and do not require care.
Knives
When knives become gummed up with pitch
carefully clean them with a strong solvent. A
knife in this condition will not only give a poor
cut it will allow heat to build up quickly thus
putting undue stress on the machine.
Dull knives can be replaced or sharpened.
Check in your local yellow pages for a
sharpening service. It may be more cost
effective to replace rather than sharpen.
Note; Do not run the machine with dull knives.
Not only will they give a bad cut, the put undue
stress and vibration on the machine thereby
decreasing the life of the machine and
damaging the cutterhead bearings
.
Table Leveling
The tables have been leveled at the factory
and should not require leveling. However, if
needed it can be done using the adjusting
bolts as seen in Figure 21. There are 6 sets
each consisting of a locking bolt and an
adjusting bolt with jam nut. It should only be
necessary to adjust one table leaving the other
table as is. Keep in mind that leveling a table
can easily turn into a long project therefore it is
best to determine what part of the table needs
adjusting before turning a bolt and to turn only
a little at a time. Also understand that
changing the position of one bolt affects all
others and that the other bolts will have to be
‘zeroed’ out. To adjust the table loosen all
lock nuts and jam nuts, adjust the appropriate
bolts and lock into place. Note: Use a good
known 4’ straight edge such as by Starrett.
