***IMPORTANT UPDATE***
For Machines Mfd. Since 07/19
and Owner's Manual Revised 06/19
The cutterhead guard is a critical safety
feature of this jointer. You MUST verify its
operation before using the jointer! Failure
to properly install this guard will greatly
increase risk of serious personal injury.
12. Verify proper operation of cutterhead guard
by setting fence to 90°, moving fence to rear
of table, then pulling cutterhead guard back
and letting it go. It should spring back over
cutterhead and contact fence without drag-
ging across outfeed table.
— If cutterhead guard does not spring back
over cutterhead and contact fence, or if it
drags across outfeed table, then it must
be adjusted (refer to Checking/Adjusting
Cutterhead Guard on Page 53 for
instructions).
