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 

Figure 19 

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.
