G1021Z 15" Planer -15-
Gauge Block
Before attempting any table adjustments, you will
need to construct a gauge block. See Figure 10.
A larger gauge block diagram is also included at
the end of the manual for your convenience.
Precision adjustments later on require accuracy
when milling the gauge block. Do not use com-
mon 2x4 material. Use maple or similar type of
hardwood.
Using a magnetic dial indicator is a good alterna-
tive to constructing a gauge block. Use the dial
indicator whenever the instructions call for use of
the gauge block and/or feeler gauge. Refer to the
current Grizzly catalog for dial indicators.
Table Adjustment
To plane stock perfectly square, it is important
that the table is parallel to the cutterhead.
TO CHECK TABLE PARALLELISM:
1. Place the gauge block on the table under
one end of the cutterhead.
2. Turn the handwheel to raise the table until
the block barely touches the cutterhead
body. The block should not be touching
the knives. See Figure 11.
3. Slide the block toward the opposite side of
the cutterhead. Use a feeler gauge to mea-
sure the width of the gap, if any, between
the top of the block and the bottom of the
cutterhead. If there is a gap, make a note,
reading the distance from the feeler gauge.
4. If the block wedges tightly between the
table and cutterhead when shifting from
one side to the other, repeat steps 1
through 3 above, but start from the oppo-
site end of the cutterhead.
Figure 10. Guide block specifications.
DO NOT make adjustments while the planer
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making adjustments.
Failure to comply could result in serious
injury or electrical shock hazard.
Figure 11. Guide block indicates parallelism.
If the gap difference from one side to the other is
equal to or less than 0.004", no further adjust-
ment is necessary.
