What are some general safety rules to follow?

• Rags, cloth, cord, string, and the like should never be left around the work area.
• Avoid cutting nails. Inspect for and remove all nails from the workpiece before operation.
• Handle the blades very carefully.
• Be sure the blade installation bolts are securely tightened before operation.
• Hold the machine firmly with both hands.
• Keep hands away from rotating parts.
• Before using the machine on an actual workpiece, let it run for a while and watch for vibration or wobbling that could indicate poor installation or a poorly balanced blade.
• Make sure the blade is not contacting the workpiece before the switch is turned on.
• Wait until the blade attains full speed before cutting.
• Keep at least 200 mm away from the machine at all times.
• Always switch off and wait for the blades to come to a complete stop before any adjusting.
• Never stick your finger into the chip chute. Clean out chips with a stick because the chute may jam when cutting damp wood.
• Do not leave the machine running. Operate the machine only when hand-held.
• When leaving the planer, switch off and set it with the front base up on a wooden block so that the blades do not contact anything.
• Always change both blades or covers on the drum; otherwise, the resulting imbalance will cause vibration and shorten machine life.
• Wait for complete run-down before putting the machine aside.
• Use only Makita blades specified in this manual.

How do you remove blades on the drum for machines with standard planer blades?

Unscrew the three installation bolts with the socket wrench. The drum cover comes off together with the blades.

---

How do you install blades for machines with standard planer blades?

1. Clean out all chips or foreign matter adhering to the drum or blades.
2. Use blades of the same dimensions and weight, or drum oscillation/vibration will result, causing poor planing action and, eventually, machine breakdown.
3. Place the blade on the gauge base so that the blade edge is perfectly flush with the inside edge of the gauge plate.
4. Place the adjust plate on the blade, then simply press in the heel of the adjust plate flush with the back side of the gauge base and tighten two screws on the adjust plate.
5. Slip the heel of the adjust plate into the drum groove, then fit the drum cover on it.
6. Tighten the three installation bolts evenly and alternately with the socket wrench.

How do you install blades for machines with mini planer blades?

1. Loosely attach the adjust plate to the set plate with the pan head screws and set the mini planer blade on the gauge base so that the cutting edge of the blade is perfectly flush with the inside flank of the gauge plate.
2. Set the adjust plate/set plate on the gauge base so that the planer blade locating lugs on the set plate rest in the mini planer blade groove, then press in the heel of the adjust plate flush with the back side of the gauge base and tighten the pan head screws.
3. It is important that the blade sits flush with the inside flank of the gauge plate, the planer blade locating lugs sit in the blade groove, and the heel of the adjust plate is flush with the back side of the gauge base. Check this alignment carefully to ensure uniform cutting.
4. Slip the heel of the adjust plate into the groove of the drum.
5. Set the drum cover over the adjust plate/set plate and screw in the three hex flange head bolts so that a gap exists between the drum and the set plate to slide the mini planer blade into position. The blade will be positioned by the planer blade locating lugs on the set plate.
6. The blade’s lengthwise adjustment will need to be manually positioned so that the blade ends are clear and equidistant from the housing on one side and the metal bracket on the other.
7. Tighten the three hex flange head bolts (with the socket wrench provided) and hand rotate the drum to check clearances between the blade ends and the machine body.
8. Check the three hex flange head bolts for final tightness.
9. Repeat procedures 1 – 9 for other blade.

How do you set up for shiplapping?

The blade edge should be made to protrude outside slightly (0.3 mm – 0.6 mm). Otherwise, nicks and generally poor shiplapping results.

---

What should you be cautious of when tightening blade installation bolts?

Tighten the blade installation bolts carefully when attaching the blades to the machine. A loose installation bolt can be dangerous. Always check to see they are tightened securely.

---

What can cause a rough and uneven planing surface?

Your planing surface will end up rough and uneven unless the blade is set properly and securely. The blade must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base.

---

How do you adjust the depth of cut?

Depth of cut may be adjusted by simply turning the knob on the front of the machine.

---

What should you check before plugging in the machine?

Before plugging in the machine, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

---

How do you start the machine without a lock button and lock-off button?

To start the machine, simply pull the trigger. Release the trigger to stop.

---

How do you start the machine with a lock button?

To start the machine, simply pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the machine from the locked position, pull the trigger fully, then release it.

---

How do you start the machine with a lock-off button?

To prevent the trigger from being accidentally pulled, a lock-off button is provided. To start the machine, press the lock-off button and pull the trigger. Release the trigger to stop.

How do you perform a planing operation?

1. Rest the machine front base flat upon the workpiece surface without the blades making any contact.
2. Switch on and wait until the blades attain full speed.
3. Move the machine gently forward. Apply pressure on the front of the machine at the start of planing, and at the back at the end of planing.

Planing will be easier if you incline the workpiece in a stationary fashion so that you can plane somewhat downhill. The speed and depth of cut determine the kind of finish. The power planer keeps cutting at a speed that will not result in jamming by chips. For rough cutting, the depth of cut can be increased, while for a good finish, you should reduce the depth of cut and advance the machine more slowly.

---

How do you make a stepped cut?

Use the edge fence.

1. Draw a cutting line on the workpiece.
2. Insert the edge fence into the hole in the front of the machine.
3. Align the blade edge with the cutting line.
4. Adjust the edge fence until it comes in contact with the side of the workpiece, then secure it by tightening the screw.

You may wish to add to the length of the fence by attaching an extra piece of wood. Convenient holes are provided in the fence for this purpose and also for attaching an extension guide (optional accessory). When planing, move the machine with the edge fence flush with the side of the workpiece; otherwise, uneven planing may result. Max. shiplapping depth is 9 mm.

---

How do you perform chamfering?

To make a cut, align the “V” groove in the front base with the edge of the workpiece and plane it.

---

How do you use the nozzle assembly?

Use of the special nozzle assembly will minimize chip scatter, making for a cleaner work area. The nozzle assembly may be attached after the chip cover on the machine body is removed. When slipping on the assembly, fit the pin on it into the rear cover hole. Use the chip cover screws to fasten it in place.

---

How do you sharpen the planer blades (standard blades only)?

Always keep your blades sharp for the best performance possible. Use the sharpening holder to remove nicks and produce a fine edge.

1. Loosen the two wing nuts on the holder and insert the blades (A) and (B) so that they contact the sides © and (D).
2. Then tighten the wing nuts.
3. Immerse the dressing stone in water for 2 or 3 minutes before sharpening.
4. Hold the holder so that the blades both contact the dressing stone for simultaneous sharpening at the same angle.
