Carefully unpack the machine and any loose items from the wood crate and inspect for damage.
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. Jointer to Planer Setup To change the machine configuration 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.
Power 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. Planer Controls and Adjustments Referring 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.
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) should rest against the fence (A). Fence Movement Referring to Figure 7: The fence (A) can be moved forward (B) or backward (C) across the width (W) of the table. It also tilts up to 45 degrees backwards (D).
Adjustments 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). 3. Raise the table (D) fully upright.
Setting Cutterhead Knives (Straight Knives Only) Important: Before performing any adjustments in this section, the infeed and outfeed tables must be coplanar (see Coplanar Alignment on page 12). 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). Referring to Figures 11 and 12: 3.
Replacing Cutter 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. 6). 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. Referring to Figures 11 and 12 (page 14): 3.
these elements can prevent the insert from seating properly, and may affect the quality of the cut. Before installing each screw, lightly coat the screw threads with machine oil and wipe off any excess. Securely tighten each screw which holds the knife inserts before operating the planer! Make sure all knife insert screws are tightened securely. Loose inserts can be propelled at high speed from a rotating cutterhead, causing injury.
Cutterhead Drive Belt Replacement 4. Loosen four motor mount screws (L). Lift the motor and rest it in the horizontal slot side of the motor mount opening. This will create a slack in the cutterhead drive belt (F). 5. Remove the cutterhead drive belt (F) from around the cutterhead pulley (E) and motor pulley (M). 6. If the feed-roller belt (K) is to be replaced, continue. Otherwise proceed to step 10.
Planer Table Adjustment Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury. Checking Planer Table Parallel to Cutterhead The planer table is set parallel to the cutterhead at the factory and no further adjustment should be needed. If your machine is planing a taper, first check to see if the knives are properly adjusted in the cutterhead (see Setting Cutterhead Knives on page 14) and make adjustments if necessary.
fence while the right hand pushes the workpiece 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 16) 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.
Direction of Grain Avoid feeding work into the jointer against the grain (Figure 18). 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). Figure 18 This may result in chipped and splintered edges. Feed with the grain to obtain a smooth surface, as shown in Figure 19. Figure 20 – Surfacing Figure 18 3.
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.
Feeding the Work The planer is supplied with planer blades mounted in the cutterhead and infeed and outfeed rollers adjusted to the correct height. The planer feed is automatic; it will vary slightly depending on the type of wood. 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.
6. Keep the cutterhead from rotating by grasping the cutterhead pulley while sliding the stone back and forth across the table. Maintenance 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.
Troubleshooting 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 Setting Cutterhead Knives. Finished stock is concave on front end. Outfeed table is higher than knife. Align cutterhead knives with outfeed table. See Setting Cutterhead Knives. Chip out. Cutting against the grain. Cut with the grain whenever possible. Dull knives.
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.
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. Overload automatic reset has not reset When planer overloads on the circuit breaker built into the motor starter, it takes time for the machine to cool down before restart.
