Ultimate Series Jointers -29-
Most of the ball bearings are permanently sealed
and lubricated so they will require no attention
until they need to be replaced. The following loca-
tions should be lubricated after approximately 80
hours of continuous use.
Cutterhead
The cutterhead has two bearings that require
grease. There are white stickers with arrows
pointing to their general location. There are two
grease fittings—one located at each end of the
cutterhead, on the top of the cutterhead axle col-
lars. The grease fitting on the front side of the
jointer is located in a small hole cut into the top of
the front base housing. The grease fitting on the
back side of the machine is located on the top of
the jointer base, just under the bottom edge of the
fence.
Handwheels
Each handwheel is lubricated via an oil cup locat-
ed just behind the handwheel body, on the axle
collar. Remove the handwheel lock knob and
slide the handwheel off the axle. This will reveal
the oil cup. Apply a small amount of light machine
oil.
Table Elevation Mechanism
The table elevation screw and gear mechanism
for each handwheel can be accessed by remov-
ing the left and right rear base housings. Apply a
generous amount of grease to the elevation
screws and gears.
Lubrication
Using sharp knives is one of the most important
factors involved with the operation of the jointer.
A good maintenance procedure is to hone the
knives to keep them in top shape. A knife hone
will polish and finely sharpen jointer knives quick-
ly and easily without removing them.
For damaged or extra dull knives, have them
resharpened by a professional grinder. To avoid
downtime from resharpening, we recommend
having an extra set of knives on hand.
The carbide cutters are typically rotated at the
same time when they become dull; however, the
cutters can also be rotated individually when one
becomes nicked or damaged. Refer to Section 8:
Service Adjustments for instructions on rotating or
replacing the carbide cutters.
