Adjusting Table Gibs
The function of the table gibs is to eliminate
excessive play in the table movement. Tight gibs
make table movement more accurate but stiff.
Loose gibs make moving the table sloppy but
easier. The goal of gib adjustment is to remove
unnecessary sloppiness without causing the ways
to bind.
Tools Needed
Qty
Hex Wrench 4mm .................................................1
Open-End Wrench or Socket 13mm .....................1
To adjust table gibs:
1.
DISCONNECT MACHINE FROM POWER!
2.
Loosen jam nuts on gib set screws (see
Figure 73) on both sides of table.
3.
Evenly tighten gib set screws a small
amount, then check table by moving it up
and down with handwheel. Adjust set screws
as needed until friction of table movement is
balanced between minimal play and ease of
movement.
4.
When satisfied with results, tighten jam nuts
on all set screws, being careful not to let the
set screws move.

Calibrating Bed Rollers
The bed rollers provide even planing pressure
from side to side and front to back by pushing the
workpiece up against the feed rollers. The height
of the table rollers can be adjusted according to
the type of material being planed.
Tools Needed
Qty
Open-End Wrenches 14, 17mm ...................... 1 Ea
Straightedge 36" ....................................................1
To calibrate table roller scale:
1.
DISCONNECT MACHINE FROM POWER!
2.
Rotate bed roller hub to "0" setting.
3.
Place straightedge across bed rollers on
left side of table. Rollers should just touch
straightedge.
— If rollers do just touch straightedge, they
are level with table. Proceed to Step 5.
— If rollers do not just touch straightedge,
they are not level with table. Proceed to
Step 4.
4.
Loosen jam nut (see Figure 74), adjust hex
bolt so roller just touches straightedge, then
tighten jam nut.
5.
Repeat
