9.0 Operating controls Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury. Cutterhead knives are dangerously sharp. Use extreme caution when working around them. Failure to comply may cause serious injury. 9.1 Jointer to Planer setup To change the machine configuration from jointer to planer (refer to Figure 2): 1. Release both cabinet table locks (A) by rotating the handles toward the operator, then pulling away from the machine. 2.
.3 Control switch Once a properly rated plug is connected, plug power cord into outlet. Press the green on button (A, Fig. 4) to start. Press the red off button (B, Fig. 4) to stop. 9.4 Planer controls and adjustments Refer to Figure 5: Power Feed Placing the planer power feed handle (D) in the up position turns the planer power feed on (see arrow). Placing the handle in the down position turns the power feed off.
2. Raise the lifting handle (E) to raise the infeed table for a shallow depth of cut. Lower the handle for a deeper cut. 3. Tighten the lock knob (D). The infeed table lifting handle in the fully lowered position results in a depth of cut of 5/32". Note: A depth of cut of 1/16" or less is recommended. Cutterhead Guard Properly positioned, the cutterhead guard (H, Fig. 7) should rest against the fence (A, Fig. 7).
10.0 Adjustments 10.1 Table and knife adjustments For accurate jointing, at least three things must be true: 1. Infeed and outfeed tables must be coplanar. 2. Knives or knife inserts must be set in the cutterhead so that the highest point of their arc is level with the outfeed table. 3. On the standard cutterhead, knives must be parallel with the outfeed table across the entire length of the knives. These alignments are explained below. Disconnect machine from power source before making any adjustments.
Performing the coplanar alignment If alignment is required as determined in the previous section, proceed as follows: Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury. 1. Disconnect power from machine. 2. Unlock both cabinet lock handles (A2,Fig. 10). 3. Raise the table (D) fully upright.
10.3 Setting cutterhead knives (straight knives only) Important: Before performing any adjustments in this section, the infeed and outfeed tables must be coplanar (see sect. 10.2, Coplanar alignment). Cutterhead knives are dangerously sharp! Use extreme caution when inspecting, removing, sharpening or replacing knives into the cutterhead. Failure to comply may cause serious injury! 1. Disconnect machine from the power source. 2. Remove the cutterhead guard (B, Fig. 8). Refer to Figures 11 and 12: 3.
10.4 Replacing cutterhead knives (straight knives only) Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury. 1. Disconnect machine from the power source. 2. Remove the cutterhead guard (B, Fig. 8). Cutterhead knives are dangerously sharp. Use extreme caution when inspecting, removing, sharpening, or replacing knives into the cutterhead. Failure to comply may cause serious injury. Refer to Figures 11 and 12: 3.
10.6 Jointer table lock handle adjustment Refer to Figure 10 on page 12: For best performance, the jointer table lock handles (A2) should be approximately in the fully down position when in the locked position. If adjustment is required: 1. Disconnect machine from power source. 2. Unlock the lock handles (A2) and raise the table to the upright position. 3. Loosen locking nut (C2) with an 18mm wrench. 4. Adjust the table locking shaft (C1) in increments of 1/4 turns or less.
Feed-roller Belt Replacement Note: If the feed-roller belt is to be replaced, steps 1–5 must be performed to remove the cutterhead drive belt before the feed-roller belt can be replaced. 7. Place the power feed handle (J) in the down (off/disengaged) position, which provides belt slack for the next step. 8. Remove the feed-roller belt (G) from around the feed-roller pulley (K) and motor pulley (M). 9. Loop the new belt around the smaller (inner) motor pulley (M) and feed-roller pulley (K).
10.9 Feed roller pressure adjustment Refer to Figure 15. The pressure of the feed rollers against the workpiece during planing operations is maintained by spring tension. To adjust this tension, turn the socket head screw (B, Figure 15), clockwise to increase pressure, counterclockwise to decrease pressure. 10.10 Planer table adjustment Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury.
in a smooth, even motion toward the cutterhead. After the cut is under way, the new surface rests firmly on the outfeed table. The left hand is transferred to the outfeed side (Figure 18) and presses down on this part of the workpiece, at the same time maintaining flat contact with the fence. The right hand presses the workpiece forward and before the right hand reaches the cutterhead it should be moved to the work on the outfeed table. 11.0 Basic operations 11.
Direction of Grain Avoid feeding work into the jointer against the grain (Figure 20). This may result in chipped and splintered edges. 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). Figure 20 Figure 22 – Surfacing Feed with the grain to obtain a smooth surface, as shown in Figure 21. 3. If the board is bowed (curved), place the concave edge down on the infeed table. 4.
For wood less than 3 inches wide – use beveled push blocks and apply pressure toward the fence. Keep fingers near top of push block. Several passes may be required to achieve the full bevel. Stock Fence Infeed Table Plane alternate sides until the desired thickness is obtained. When half of the total cut has been taken from each side, the board will have a uniform, moisture content and additional drying will not cause it to warp. The depth of cut should be shallower when the workpiece is wider.
Avoiding Snipe Snipe refers to a depression at either end of the board caused by an uneven force on the cutterhead when the work is entering or leaving the planer. Preparation: Feed rate refers to the rate at which the lumber travels through the planer. The operator is responsible for aligning the work so it will feed properly. Raise or lower the rollercase to get the depth of cut desired. The surface that the planer produces will be smoother if a shallower depth of cut is used.
6. Keep the cutterhead from rotating by grasping the cutterhead pulley while sliding the stone back and forth across the table. 12.0 Maintenance 12.1 Blade care 7. Take the same amount of passes for all three blades. Blades are extremely sharp! Use caution when cleaning or changing. Failure to comply may cause serious injury! The condition of the blades will affect the precision of the cut. Observe the quality of the cut that the planer produces to check the condition of the blades.
14.0 Troubleshooting the JJP-12,JJP-12HH 14.1 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. 10.3, Setting cutterhead knives. Finished stock is concave on front end. Outfeed table is higher than knife. Align cutterhead knives with outfeed table. See sect. 10.3, Setting cutterhead knives. Chip out. Cutting against the grain.
14.2 Performance troubleshooting – Planer Trouble Probable Cause Remedy Snipe Table rollers not set properly. Adjust rollers to proper height Inadequate support of long boards. Support long boards with extension rollers. Uneven feed roller pressure front to back. Adjust feed roller tension. Dull knives. Sharpen knives/Rotate knife inserts. Lumber not butted properly. Butt end to end each piece of stock as they pass through. Planing wood with high moisture content.
14.3 Mechanical troubleshooting – Planer/Jointer Trouble Probable Cause Remedy Chain jumping. Inadequate tension. Adjust chain tension. Sprockets misaligned. Align sprockets. Sprockets worn. Replace sprockets. No incoming power. Verify unit is connected to power, on-button is pushed in completely, and stop-button is disengaged.
