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 panel (A, Figure 28)
by removing the four corner screws. With
medium finger pressure the belt should push in
approximately ½” about midway between the
pulleys. If there is too much play, adjust the
tensioning bolts (A, ,Figure 29). First loosen the
two nuts (not shown in the picture) underneath
the motor bracket and then turn down the top
nuts to increase the belt tension.
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
Over time the table gibs will wear causing the
tables to become un-parallel. At this time it
becomes necessary to tighten the gibs using the
set screws (A, Figure 30). First loosen the jam
nuts and then turn in the set screws until they
make good contact with the gibs. Tighten the
jam nuts.
