7.3 Jointer-Planer assembly 5. Refer to Figure 9: Using a 4mm hex wrench (provided), turn setscrews slightly clockwise to raise the table or counterclockwise to lower the table. Fence Lock Handle 1. Refer to Figure 10: Attach jointer fence (A) to back of jointer outfeed table (D3) with two each socket head cap screws (Q) and lock washers (S). Tighten screws with 5mm hex wrench (provided). 6. Attach planer table lock handle (N) and flat washer (M). Cutterhead Guard 7.
screw underneath the chute meshes with three positioning holes on the table (D1). 6. 7. Cutterhead knives are dangerously sharp. Use extreme caution when working around them. Failure to comply may cause serious injury. Raise the table (turn handle L clockwise) until the dust chute (B) is held firmly in place between the planer infeed table (D1) and jointer outfeet table (D2). Do not overtighten. 2. Tighten lock handle (N). Step 8 is optional. Orient the dust chute (B) as shown.
10.2 Planer controls and adjustments Note: A depth of cut of 1/16" or less is recommended. Refer to Figure 14: Table Lock Turn the lock handle (A) counterclockwise to release and permit table adjustment. Turn the lock handle (A) clockwise to secure the planer table (D) in its selected position. Table Height Adjustment The planer table height is set as follows: 1. Unlock the table lock (A). 2. Install the removeable adjustment handle (C) onto the shaft (B). 3.
1. Loosen lock handle (J). 2. Tilt the fence (B2) back to the desired angle up to 135 degrees (G). Or you can place your beveled reference piece on the table and against the fence, adjusting the fence until the angle of the fence matches the bevel of your gauge piece. 3. 7. When the blade is at the proper height, alternately tighten the six gib lock screws (A). Repeat steps 3 – 7 to adjust the remaining blade.
11.2 Replacing Cutter Knives If setting to maximum positions do not stop the fence at 0º or 90º, make adjustments as follows: Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury. Fence 90º Adjustment 1. Disconnect machine from the power source. 2. Remove the cutterhead guard. 1. Loosen lock handle (H) and bring fence fully forward. Using a square, determine if the fence is 90º to the table.
4. When installed, continue to manually rotate pulley (C) and verify that belt is properly seated on both pulleys. 6. 5. Replace front cover. Use extreme caution to avoid contact with cutterhead knives while performing this step. Contact with cutterhead knives will cause serious injury. 7. Loop belt around pulley (E) while manually rotating pulley (F). Manually rotate pulley (F) to verify that the grooves in the belt are properly meshed with the grooves on both pulleys.
12.4 Jointer operations Correct operating position The operator must be positioned offset to the infeed table (Figure 20). Figure 21 Direction of Grain Avoid feeding work into the jointer against the grain (Figure 22). This may result in chipped and splintered edges. Figure 20 Hand placement Never pass hands directly over the cutterhead.
To edge: 1. Make sure the fence is set to 90°. Double check it with a square. 2. Inspect stock for soundness and grain direction (refer to Direction of Grain on previous page). Several passes may be required to achieve full bevel. Figure 25 12.5 Planer operations Depth of Cut Thickness planing refers to the sizing of lumber to a desired thickness while creating a level surface parallel to the opposite side of the board.
Check the accuracy of the test cut before working on the finished product. Planing 1. Precautions A thickness planer is a precision wood-working machine and should be used on quality lumber only. Note: Feed direction is left to right (see Figure 12). Do not plane dirty boards; dirt and small stones are abrasive and will wear out the blade. Remove nails and staples. Use the planer to cut wood only. Avoid knots. Heavily cross-grained wood makes knots hard.
13.0 Maintenance 4. Lay the stone on the infeed table. 5. Lower the infeed table and turn the cutterhead by turning the cutterhead pulley. The infeed table height is set properly when the stone's surface is flush with the knife bevel. 6. Keep the cutterhead from rotating by grasping the cutterhead pulley while sliding the stone back and forth across the table. 7. Take the same amount of passes for all two blades. 13.1 Blade Care Blades are extremely sharp! Use caution when cleaning or changing.
16.0 Troubleshooting the JJP-8BT 16.1 Performance Troubleshooting – Jointer Trouble Probable Cause Remedy Finished stock is concave on back end. Knife is higher than outfeed table. Align cutterhead knives with outfeed table. See sect. 11.1, Cutterhead Knife Adjustment. Finished stock is concave on front end. Outfeed table is higher than knife. Align cutterhead knives with outfeed table. See sect. 11.1, Cutterhead Knife Adjustment. Chip out. Cutting against the grain.
16.2 Performance Troubleshooting – Planer Trouble Probable Cause Remedy Snipe Inadequate support of long boards. Support long boards with extension rollers. Note: Snipe can be minimized but not eliminated Dull knives. Sharpen knives. Lumber not butted properly. Butt end to end each piece of stock as they pass through. Fuzzy Grain Planing wood with high moisture content. Remove high moisture content from wood by drying. Dull knives. Sharpen or replace. Too heavy a cut.
16.3 Mechanical Troubleshooting – Planer/Jointer Trouble Probable Cause Remedy Machine will not start/ restart or repeatedly trips circuit breaker or blows fuses. No incoming power. 1. Verify unit is connected to power and Start/Stop switch is in the Start position (see sect. 10.1, Power). 2. Verify unit is connected to power. Set the Start/Stop switch to the Stop position, depress and release the reset switch, then reset the Start/Stop switch to the Start position (see sect. 10.1, Power).
