4235 Jointer 

Problem

 

Possible Cause

 

Possible Solution

 

Table is loose. 

There is play in the 
parallelogram 
mechanism. 

Check the parallelogram mechanism and eliminate 
any gaps between the eccentric nut, bracket, and 
shafts. Ensure all eccentric nuts are locked by the set 
screws, and each set screw is locked by blue Loctite. 

Workpiece is caught 
on the edge of the 
outfeed table. 

Outfeed table is set 
too high. 

Adjust the outfeed table to ensure it is flush with the 
cutting arc of the cutterhead. 

Uneven wear on 
cutter inserts 

One section of 
cutterhead is used 
more than another. 

Occasionally adjust fence position so the entire 
cutterhead is utilized. 

Machine vibrates 
excessively or makes 
unexpected noise. 

Damaged cutter 
inserts. 

Replace cutter inserts. 

Machine stands on an 
uneven floor. 

Reposition machine on a flat, level surface. 

V-belt worn, slipping, 
or hitting belt cover. 

Clean belt and pulleys. Adjust belt tension. Replace 
V-belt if it shows signs of aging. 

Improper motor 
mounting. 

Check and adjust motor mounting. 

Loose components. 

Tighten fasteners of the component.  

Worn bearings. 

Contact customer service for assistance. 

 

 

Operation / Quality-Related Issues 

Problem 

Possible Cause 

Possible Solution 

Workpiece came out 
twisted. 

Improper feeding. 

Use the outfeed table as the reference point for 
feeding. Apply even pressure and feed rate on 
the entire workpiece. 

Outfeed table is not in 
parallel with the 
cutterhead. 

Ensure the outfeed table is in parallel with the 
cutterhead, and the outfeed/infeed tables are 
coplanar.  

More passes are 
needed. 

Significantly twisted boards take multiple passes 
to flatten. 

Excessive snipe 

Outfeed table too low. 

Adjust the outfeed table to ensure it is flush with 
the cutting arc of the cutterhead. 

Too much downward 
pressure when feeding 
the end of the 
workpiece. 

Once the workpiece reaches the outfeed table, 
use the outfeed table as the reference. Reduce 
feeding pressure apply to the workpiece that is 
still on the infeed table.
