Setup

Unpacking and Inspection

Carefully remove all components from the packaging. Inspect the planer for any signs of damage that may have occurred during shipping. If any damage is found, do not operate the tool and contact your dealer or Makita service center. Retain packaging materials for future transport or storage.

Power Connection

Ensure the planer is connected to a suitable 120 Volt, 15 Amp power source. The L.E.D. light on the control panel will illuminate to indicate a successful power connection.

Table Extensions

Extend the large table extensions on both the in-feed and out-feed sides to provide adequate support for your workpiece. Ensure they are securely locked in place to prevent movement during operation.

Blade Installation/Inspection

The planer uses disposable double-edge blades. Before first use, or if changing blades, ensure they are correctly installed and sharp. Refer to the 'Maintenance' section for detailed instructions on blade replacement. Always disconnect power before performing any blade-related tasks.

Operating Instructions

Adjusting Cutting Depth

To set the desired cutting depth, use the adjustment knob located on the top of the planer. Rotate the knob to raise or lower the cutter head. The depth scale on the side of the planer indicates the current cutting depth. The maximum thickness capacity for a workpiece is 6-3/32 inches.

Powering On and Off

To start the planer, press the green 'ON' button on the large paddle switch. To stop the planer, press the red 'OFF' button. Always ensure the planer has come to a complete stop before leaving the machine or performing any adjustments.

Planing Operation

With the planer running, carefully feed the workpiece into the in-feed side. The planer's feed rate is approximately 28 feet-per-minute. The Interna-Lok automated head clamp is designed to minimize snipe, which is the slight depression at the beginning or end of a board. For optimal results, especially with longer workpieces, provide additional support at both the in-feed and out-feed ends.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Makita 2012NB planer. Always disconnect the planer from the power source before performing any maintenance.

Blade Changes

The 2012NB features a system for fast and easy blade changes using disposable double-edge planer blades. When blades become dull, they should be replaced to ensure a smooth finish and prevent strain on the motor. Refer to the detailed instructions in the full product manual for the exact blade replacement procedure, utilizing the included magnetic holders and wrenches.

Cleaning

After each use, clean the planer to remove sawdust, chips, and resin buildup. Use a brush or compressed air to clear debris from the cutter head area, feed rollers, and table surfaces. An optional dust hood can be connected to a dust collection system for more efficient chip removal during operation, significantly reducing cleanup.

General Inspection

Periodically inspect all moving parts, fasteners, and the power cord for signs of wear, damage, or looseness. Ensure all guards and safety features are in place and functioning correctly. Lubricate moving parts as recommended in the comprehensive manual to ensure smooth operation.

Troubleshooting

This section addresses common issues you might encounter with your Makita 2012NB planer.

Common Issues and Solutions

• Excessive Snipe: While the Interna-Lok system is designed to minimize snipe, ensure proper in-feed and out-feed support for long workpieces. Adjust the depth of cut to a shallower pass if snipe persists.
• Poor Surface Finish (Roughness, Tear-out): This often indicates dull or damaged blades. Inspect the blades and replace them if necessary. Ensure blades are installed correctly and are clean.
• Planer Not Powering On: Verify the power cord is securely plugged into a functional outlet. Check that the L.E.D. light is illuminated. Ensure the paddle switch is fully engaged to the 'ON' position. Check for tripped circuit breakers.
• Workpiece Stalling or Not Feeding: Ensure the feed rollers are clean and free of resin buildup. Adjust the cutting depth to a lighter pass, especially for hard or wide materials.
