Warning: DISCONNECT MACHINE FROM POWER!
TABLE ALIGNMENT
The alignment of the infeed and outfeed tables has been precisely set at the factory. However, misalignment can be incurred from shipping movement. Follow these steps to check and adjust.
OVERVIEW
These instructions are intended to assist when the alignment of the infeed, outfeed or both tables require adjustment. It is important to note that the outfeed table must be parallel and flush with the cutter head before adjusting the infeed table. Always make this adjustment first if needed. If the infeed table cannot be adjusted parallel to the outfeed table (e.g. not enough adjustment within the eccentric adjustment collars), then the outfeed table will require adjustment to bring into the same plane as the infeed table, but the outfeed table must ALWAYS remain parallel and flush with the cutter head. Always make this adjustment first if needed.
Coplanarity Test
STEP 1: DISCONNECT THE MACHINE FROM POWER!
STEP 2: Remove the cutterhead guard by loosening the set screw(s) and
removing guard. (See GUARD INSTALLATION).
STEP 3: Slide the fence assembly back. Remove knob for depth stop. Loosen
the set screws for all table covers and cutterhead guard, remove (by lifting)
covers.
STEP 4: Place a straight edge across the tables in positions as shown in
FIG. 1. In each position, the straight edge should rest flat and fit flush
with both infeed and outfeed tables (not on an insert knife). If it does not,
follow the steps in Outfeed Table and Infeed Table adjustments.
Outfeed Table
Paralleling to cutter head and establishing proper height to the cutter
head.
STEP 1: While the machine is disconnected from the power source, the
cutter head guard is removed, and the fence is Away or removed; remove the
rear access panel of the stand to access the pulley.
STEP 2: Rotate pulley to access cutter head. Place a straight edge on the
outfeed table halfway over the cutter head.
STEP 3: Use a hex wrench (not included) to Loosen Screw Lock and release outfeed table adjustment Lever as shown in Figs. 3A & 4.
STEP 4: If necessary, loosen Stop Bolt(s) and Jam Nut(s) to adjust the
outfeed table until the straight edge just touches the inserts of the cutter
head. Rotate cutter head if necessary for an inserted knife to touch straight
edge at its highest point of rotation TDC (top-dead-center).
STEP 5: Place a straight edge in the positions shown in FIG. 5 to confirm
the outfeed table is parallel and flush with the cutter head inserts.
EP 6: If the outfeed table requires adjustment to make it parallel to the
cutter head; loosen the set screws for the eccentric bushings Fig. 5. Rotate
the eccentric bushings to adjust the outfeed table parallel to the cutter
head. Tighten set screws in eccentric bushings. Make sure the bushing is
seated tight to the bracket before tightening set screws. See “Trouble
Shooting”.
STEP 7: Confirm the outfeed table is flush with the knife inserts. Rotate
knives to the top of the arc (highest point, top-dead-center) when checking
with a straight edge. Loosen lock and adjust with outfeed lever if necessary.
Tighten the lock when adjusted.
Infeed Table
STEP 1: Before checking parallelism on the infeed table, confirm the
outfeed table is parallel and flush with the insert tips of the cutter head.
Rotate cutter head if necessary for insert to be at the highest point when
checking.
STEP 2: Place a straight edge across infeed and outfeed tables as in FIG.
6. If knife inserts interfere with the straight edge, rotate the cutter head.
STEP 3: Place straight edge in positions shown in FIG. 7.
STEP 4: If straight edge lies uniformly flat against both infeed and outfeed tables in all positions; re-install fence, blade guard, and rear access panel. If it does not fit uniformly flat against both infeed tables and outfeed tables i n any position, go to Table Parallelism Adjustment.
Table Parallelism Adjustment
When the infeed table is not parallel with the outfeed table, it can be
adjusted. NOTE: This adjustment needs to be done very precisely and typically
does not require re-adjustment once set.
Before following the steps below, double-check the alignments as shown in
Infeed Table to be certain that table adjustment is required.
STEP 1: Place a straight edge on the outfeed table over the cutter head
and slightly touch the cutter head body as shown in FIG. 8, with an inserted
knife at the top-dead-center touching the straight edge.
STEP 2: Remove the plugs and loosen CAP screws, with a hex wrench, to release and remove table covers and cutterhead cover as in FIG. 9.
STEP 3: Loosen set screws (4 for each table) example shown in FIG. 10 & 13.
STEP 4: Place a straight edge to all the positions shown in FIG. 11 and adjust the eccentric bushings as in FIG. 10 until the straight edge slightly touches the cutter head body on each position.
STEP 5: After verifying the parallelism on the outfeed table, tighten all
four set screws in eccentric bushings, examples in FIG. 10.
STEP 6: Remove infeed table depth stop release knob and infeed table
cover, loosen set screws and place a straight edge across infeed and outfeed
tables as in FIG. 12, and adjust eccentric bushings under infeed table as STEP
4 for the outfeed table.
STEP 7: Verify parallelism in each position as in FIG. 12, tighten set
screws in eccentric bushings on infeed table.
STEP 8: Re-install table covers and infeed table depth stop release knob.
NOTE: Confirm Eccentric Bushings are fully seated (hex collar pushed snug
into the bracket) before tightening Set Screws. This prevents excessive play
and side-to-side bed movement.
Troubleshooting
Fence: After adjusting either or both tables, check and if necessary
adjust the fence according to fence setting instructions within the main
manual.
Before making adjustments: Always confirm the outfeed table is parallel
and flush with the cutter head before adjusting the infeed table.
The Infeed table cannot be adjusted parallel to the outfeed table: If
there is not enough adjustment available with the infeed table eccentric
collars to align with the outfeed table; adjust the outfeed table using the
four eccentric collars to coplanarity to the infeed table. It is important to
maintain the outfeed table flush and parallel with the cutter head when
adjusting the outfeed table for coplanarity.
Infeed or Outfeed Table lose, side-to-side: If either the infeed or
outfeed table are loose (side-to-side), it is probably due to lose eccentric
bushings and set screws in the height adjustment mechanism. Check table
alignment first and eccentric bushings last by following through the previous
instructions and “NOTE” after STEP 8 of “Table Parallelism Adjustment”.
