Maintenance
Disconnect machine from
power source before performing any
maintenance. Failure to comply may cause
serious injury.
Check all screws and fasteners occasionally and
keep them tightened securely.
Inspect cords; a cord that is frayed or damaged
in any way should be replaced immediately.
The table and fence surfaces must be kept
clean and free of rust for best results. Some
users prefer a paste wax coating. Another option
is talcum powder applied with a blackboard
eraser rubbed in vigorously once a week; this
will fill casting pores and form a moisture barrier.
This method provides a table top that is slick
and allows rust rings to be easily wiped from the
surface. Important also is the fact that talcum
powder will not stain wood or mar finishes as
wax pickup does.
Lubrication
The cutterhead runs in two single-row sealed
and shielded ball bearings, which are pre-
lubricated for life - no maintenance is necessary.
Occasionally apply a good grade of light grease
to areas of the jointer where friction may occur,
such as when the tables are raised or lowered.
Cutterhead Repairs
The entire cutterhead assembly may be
removed for bearing replacement or other
cutterhead maintenance procedures. The
procedure is identical for both helical and
straight cutterheads.
To remove the cutterhead:
1. Disconnect machine from power source.
2. Remove rabbeting ledge and fence.
3. Lower infeed and outfeed tables until they
are clear of the cutterhead.
4. Remove belts.
5. Remove the two hex cap screws and lock
washers that hold the cutterhead to the bed
– these are accessed from the underside of
the bearing blocks as shown in Figure 32.
Before removing cutterhead,
wrap it with several cloths to prevent
personal injury.
