MAINTENANCE
WARNING! To avoid cuts, wear cut-proof or cut-resistant gloves when performing maintenance work on the
blades. Remove the gloves before operating the jointer.
REPLACING OR ROTATING BLADES
Your jointer is equipped with a helical cutting head consisting of 12 blades. Each blade is indexed with a small dot
in the corner to denote the two sharp sides of the blade. Once a side of the blade is dull or nicked, use the star
head wrench to remove the retaining screw to rotate or replace the blade. The blades are machined to be properly
positioned once the retaining screw is tightened, but make sure that all dust and debris is cleared away to help the
blade be seated properly. Make sure that the unit is unplugged from the power supply before changing any blades.
NOTE: To avoid cuts, wear cut-proof or cut-resistant gloves when performing maintenance work. Remove the
gloves before operating the jointer.
1. Insert the 4 mm hex wrench at the front of the cutterhead under the blade guard flange to hold the cutterhead
still while working with the blades.
2. Use the star wrench to remove the retaining screw and the blade from the cutterhead.
3. While the blade is removed, check the cutterhead for any resin build up or dust that is stuck around the blade
location. Use a brush (such as an old toothbrush) and suitable solvents to clean the cutterhead so that the blade will
be seated properly.
4. Rotate or replace the blade to the desired position. Be sure to note the position of the small dot to ensure the blade
is being installed with a new sharp edge (Fig. 18).
5. Tighten the retaining screw back on the cutterhead to hold the blade in place. Do not overtighten the retaining
screw as this might damage the blade. Make sure that the screw is only tightened with a torque of about 50 lbs.
CLEANING & STORAGE
1. After every operation, use a vacuum to remove dust and chips from the tool surfaces, motor housing and work
area. Keep the ventilation openings free from dust and debris to prevent the motor from overheating.
2. Wipe the tool surfaces clean with a soft cloth or brush. Make sure water does not get into the tool.
3. Lubricate the table bracket and locking knobs if they become difficult to use.
