Frequently Asked Questions - KP312 MAKITA

How to adjust the cutting depth on the Makita KP312 planer?

Turn the knob located at the front of the tool until the pointer aligns with the desired depth on the scale. The maximum depth depends on the cutting width: for 0-150 mm, max 3.5 mm; for 150-240 mm, max 2 mm; for 240-312 mm, max 1.5 mm. Refer to the table in the manual.

How to change the planer blades?

Make sure the tool is unplugged. Loosen the eight fixing bolts one turn with the provided socket wrench. Slide the used blade sideways using the heel of the wrench. To install the new blade, insert it between the drum and the clamping plate, centered. Tighten the bolts alternately, from the center outward, until they are securely fastened. Always use two identical blades and replace them as a pair.

How to use the parallel guide?

The parallel guide is integrated on the side of the tool. Press the two tabs to extend it. When planing, keep the flat surface of the guide in contact with the edge of the workpiece. This allows for uniform width cuts. To retract it, push it upward from its bottom surface.

Why is my planer vibrating excessively?

Vibrations can be caused by improperly installed or unbalanced blades. Check that the blades are correctly tightened and that their edges are parallel to the rear sole. Always replace both blades at the same time to avoid imbalance. Use only recommended Makita blades.

How to connect a vacuum cleaner to the planer?

Use the optional nozzle and adapter (accessory). Remove the chip deflector on the tool body, then attach the nozzle with the screws. Connect the vacuum hose to the adapter. This reduces chip dispersion and keeps the workspace cleaner.

What to do if the planer does not start?

Check that the tool is plugged into a functioning outlet. Ensure the trigger presses properly and returns to the off position. If the lock is engaged, the trigger may be blocked. If the problem persists, take the tool to an authorized Makita service center.

How to store the socket wrench after use?

The socket wrench can be stored on the tool itself. A storage location is provided, as illustrated in the manual. Insert the wrench into its slot to avoid losing it.

How to protect the blades after a planing operation?

After finishing planing, tilt the tool backward. A rear shoe then deploys below the level of the rear sole, preventing the blades from contacting a surface. You can also place the tool on a block of wood with the front sole raised.

What is the maximum cutting depth depending on the planing width?

The maximum depth is limited by the cutting width: up to 150 mm width, max depth 3.5 mm; between 150 and 240 mm, max depth 2 mm; between 240 and 312 mm, max depth 1.5 mm. Respect these limits to avoid damaging the tool.

How to maintain and clean the planer?

Always unplug the tool before any maintenance. Clean the ventilation slots and chip ejection chute with a wooden stick. Regularly check the carbon brushes and replace them when worn to the limit mark. Use only Makita replacement parts.

GENERAL SAFETY RULES

USA002-2

(For All Tools)

WARNING:

Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

Work Area

1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

1. Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation ☐ eliminates the need for the three wire grounded power cord and grounded power supply system.

2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.

3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
5. When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric shock.

Personal Safety

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.
4. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

6. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Ordinary eye or sun glasses are NOT eye protection.

Tool Use and Care

1. Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
2. Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
3. Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
4. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.
7. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
8. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

SERVICE

1. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

2. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of electric shock or injury.

USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

Removing or installing planer blades

CAUTION:

• Tighten the blade installation bolts carefully when attaching the blades to the tool. A loose installation bolt can be dangerous. Always check to see they are tightened securely.
• Handle the blades very carefully. Use gloves or rags to protect your fingers or hands when removing or installing the blades.
• Use only the Makita wrench provided to remove or install the blades. Failure to do so may result in overtightening or insufficient tightening of the installation bolts. This could cause an injury.

To remove planer blades from the drum, loosen the eight installation bolts by only one full turn with the socket wrench. Then push and slide a planer blade sideways from the belt side using the helm of the socket wrench.

To remove another planer blade, follow the same procedure as above.

To install the blades, first clean out all chips or foreign matter adhering to the drum or blades.

Technical line drawing of a mechanical component with mounting holes and a handle (no text or symbols)

Insert the blade between the drum and the set plate from the nozzle extraction side so that the blade will be centered from both ends of the drum or set plate.

First tighten the eight installation bolts lightly and evenly shifting from the center bolts to the outward bolts with the socket wrench.

And then, tighten all of the installation bolts securely. Install another blade in the same manner as above.

For the correct planer blade setting

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.

Below are some examples of proper and improper settings.

Connecting to vacuum cleaner

When you wish to perform cleaner operation, connect a vacuum cleaner to your tool. Connect a hose of vacuum cleaner to the joint.

Planing operation

First, rest the tool front base flat upon the workpiece surface without the blades making any contact. Switch on and wait until the blades attain full speed. Then move the tool gently forward. Apply pressure on the front of tool at the start of planing, and at the back at the end of planing.

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 tool more slowly.

Front roller

When performing repeated cuts, the use of the front roller enables quick and effortless return of the tool toward an operator by raising the back end of the tool so that the tool blades do not contact a workpiece and then sliding tool on the front roller.

MAINTENANCE

CAUTION:

- Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
