| 4. Check V-belt for wear and damage.
| |
| | |
| 5. Check other conditions that could hamper the safe operation of this machine.
| |
| | |
| 6. Since bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. Do not lubricate them.
| |
| | |
| 7. Table ways and the fence assembly should not be lubricated. If the tables appear to be stuck, disassemble and clean any foreign materials from the ways. Re-assemble and reset the gibs.
| |
| | |
| 8. Inspect regularly for tension and wear; replace when necessary with a size A-36 belt. Check pulleys to ensure that they are properly aligned. See pulley/V-belt sections for proper tension and pulley alignment procedures.

| '''ADJUSTMENTS'''
| |
|
| |
|
| '''Table Gibs:''' The function of the gibs are to allow precise adjustment of the table movement along the dovetail ways. Adjustment of the gib will dictate how easy it will be to move the tables up and down with the levers or hand wheels. To adjust gibs:
| |
| 1. Unscrew the upper and lower check nuts on the infeed table several turns, leaving the lock handle tight. See Figure 14.
| |
| 2. With one hand securely on the lever bar, loosen the table lock handle and adjust the upper and lower gib setscrews until table movement is smooth and controlled.
| |
| 3. Once the gib has been properly adjusted, tighten check nuts and repeat Steps 1-2 for the outfeed table.
| |
| 4. Make sure there is no side-to-side movement of the tables once the check nuts have been tightened. If there is, repeat Steps 1-4.

| '''KNIFE INSPECTION:''' The knives of your jointer must be periodically replaced or adjusted. Adjustments should be as precise as possible with tolerances within .002"- .003" to prolong the sharpness of the knife edges. Improperly adjusted knives can unbalance the cutterhead and shorten bearing life, as well as produce substandard jointing or planing results. The knives are set at the factory using jack screws before shipping. Springs are also included in the cutterhead supplied with your machine. They may be used instead of the jack screws depending on your preference. Now is a good time to double-check the knife settings. To inspect and adjust knife set:
| |
| 1. Unplug the jointer!
| |
| 2. Remove the upper cover or cutterhead guard to expose the top of the cutterhead.
| |
| 3. Carefully turn the cutterhead (using the pulley) until the first knife is at top dead center.
| |
| 4. Using the knife setting gauge, check the knife height. The jig should sit solidly with both feet on the cutterhead. See Figure 15. If the knife is adjusted properly, the contact point at the center of each adjuster should just touch the tip of the knife. If the knife does not make contact, or if the knife causes the adjuster’s legs to not seat on the cutterhead, the knives need to be adjusted.

| |
| '''ADJUSTMENTS USING JACK SCREWS:''' When using jack screws, it is not necessary to install the springs. The knives are locked into the cutterhead with wedge-type gibs and gib bolts. Jack screws under the knives allow fine tuning to help in the setting process. To realign the knives:
| |
| 1. Unplug the jointer!
| |
| 2. Loosen the gib bolts until the knife is loose in the slot. The gib bolts turn clockwise to loosen and counterclockwise to tighten (when facing the head of the bolt). See Figure 16 and 16B.
| |
| 3. Place the knife setting gauge on the cutterhead as described previously, so the feet are securely planted on the cutterhead.
| |
| 4. Adjust the screws below each end of the knife until both feet of the gauge rest evenly on the cutterhead and the knife is just touching the bottom of the middle foot of the gauge. The gauge will set the knives at a uniform protrusion of approximately .070" above the cutterhead. The knife height should vary no more than .002"-.003" across the length of the cutterhead.
| |
| 5. Maintain a constant pressure on the gauge while retightening the gib bolts.
| |
| 6. Repeat the same procedure on the remaining knives. As mentioned before, the standard knife setting gauge is satisfactory for reasonably accurate knife setting tasks.

| '''ADJUSTMENTS USING SPRINGS:''' The knives are locked into the cutterhead with wedgetype gibs and gib bolts. Jack screws under the knives may be substituted with springs to help in the setting process. When using springs, it is advised that the jack screws be removed. To realign the knives:
| |
| 1. Unplug the jointer!
| |
| 2. Loosen the gib bolts until the knife is loose in the slot. The gib bolts turn clockwise to loosen and counterclockwise to tighten (when facing the head of the bolt). Remove the knife and jack screws.
| |
| Place 1 spring in each of the two holes in bottom of the knife slot. See Figure 16A and 16B.
| |
| 3. Place the knife setting gauge on the cutterhead as described previously, so the feet are securely planted on the cutterhead. Make sure the gauge extension rod is parallel to the cutterhead to maintain accuracy.
| |
| 4. The downward pressure provided by the gauge will set the knives at a uniform protrusion of approximately .070" above the cutterhead. The knife height should vary no more than .002"-.003" across the length of the cutterhead.
| |
| 5. Maintain a constant pressure on the gauge while retightening the gib bolts.
| |
| 6. Repeat the same procedure on the remaining knives. As mentioned before, the standard knife setting gauge is satisfactory for reasonably accurate knife setting tasks.

| '''OUTFEED TABLE:''' Facing the fence, the outfeed table is located to the left of the cutterhead. The outfeed table must be aligned to the highest point of the arc of the blades. If it is set too high, the board will hit the front edge of the table and be impossible to feed over the jointer. If the table is set too low, the back end of the board will fall into the cutterhead and snipe will occur.
| |
| 1. Loosen the table stop bolt jam nut under the outfeed table. Turn the table stop bolt counter-clockwise several times so that it will not interfere when setting the correct table height. See Figure 17.
| |
| 2. Rotate the cutterhead by turning the motor pulley. DO NOT grab the cutterhead itself. Bring one blade to the approximate apex of its arc.
| |
| 3. Position a steel straightedge on the outfeed table. Extend the straightedge over the middle of the cutterhead. See Figure 18.
| |
| 4. Loosen the table lock handle and raise or lower the table with the lever until the straightedge barely touches one of the knives. Rock the cutterhead to ensure that the blade is at the highest point of its arc. Check the other two blades in the same manner. If they do not all touch the straightedge evenly, they are not at the same height. You must reset the knives. Be sure to test the height at both ends of the cutter knives. The knives must be parallel to the table surface.
| |
| 5. Adjust the stop bolt until it touches the cast base. Tighten the table lock handle.
| |
| 6. Tighten the checknut, loosen the table lock handle, and move the table down with the lever – then up against the stop. Check the accuracy of the stop setting with a straightedge over the cutterhead and fine tune if necessary.

| '''OUTFEED TABLE:'''
| |
| 1. Loosen the jam nut and unscrew the table stop bolt out 3 or 4 turns. See Figure 19.
| |
| 2. Place a straightedge on the outfeed table so it hangs over the infeed table. Turn the cutterhead so that the knives are NOT touching the straightedge.
| |
| 3. Loosen the infeed table lock handle. Raise the infeed table until it just touches the straightedge. Tighten the table lock handle.
| |
| 4. Turn the stop bolt until it makes contact with the base casting.
| |
| 5. Tighten the jam nut, loosen the table lock handle, and move the table up and down to check your settings. Align the depth of cut scale to read zero.

| '''90 Degree FENCE STOP:'''
| |
| 1. Place a square on the outfeed table fairly close to the cutterhead. See Figure 20.
| |
| 2. Loosen the fence lock handle and the checknut on the positive stop bolt. Turn the bolt against the tab until the fence contacts the edge of the square evenly.
| |
| 3. Tighten the checknut on the stop bolt and tilt the fence forward, then back against the stop. See Figure 21.
| |
| 4. Re-check with the square. Tightening the checknut will move the stop bolt slightly, so some trial-and-error may be necessary to perfect your settings.

| |
|
| |
| '''45 Degree FENCE STOP:''' The fence can be tilted to 45° by loosening thelock handle, lifting up the 90° positive stop tab, and moving the fence in the desired direction. To set the 45° tab stop:
| |
| 1. Loosen checknut and lower fence until it rests on the stop bolt. See Figure 22.
| |
| 2. Using a bevel gauge set to 45°, place the heel of the bevel on the outfeed table and the blade against the fence.
| |
| 3. If there is a gap between the bevel’s blade and the face of the fence, turn the stop bolt until the gap is gone.
| |
| 4. Tighten jam nut. Move your fence forward, then back against the stop. Recheck the stop bolt.
