Safety Check Prior to Operation

Warning: Unplug the machine and turn the power switch OFF before inspecting the machine.

1.Check to be sure all parts and fasteners are properly attached and tight.

.

Be sure the blade is properly installed and adjusted.

3.Check the operation of the Table Adjustment Handle (150). One rotation of the handle will raise or lower the table by 2mm (0.0787”).

Plug in the machine to prepare to check the motor and blade function.

1.Turn ON the machine by moving the switch up. Note: The safety switch cover must be in place for the switch to operate.

.

Do not insert any work materials into the planer. Allow it to spin up to full speed. Determine if the

 

machine is operating smoothly, not making any excessive noises or vibrations. If not, the machine

 

is ready to operate.

 

Warning: check blade setting and tightness before initial use.

Operation

WARNING:Wear ANSI-approved eye protection, and observe all safety precautions when operating.

1.Measure your workpiece to determine its current thickness, and the amount you desire to plane off. Maximum depth of cut is 1/8”; if you need to remove more than this, make repeated cuts.

.

Set the cutting depth by turning the Table Adjustment Handle (150) until the pointer indicates the

 

correct depth on the scale.

3.Turn the machine OFF and unplug the power cord. Insert the workpiece into the planer and visually check your setting to assure that no more than 1/8” will be planed off the workpiece.

Warning: Attempting to plane more than 1/8” at a time may cause the planer to jam; potentially causing the workpiece to splinter and be ejected from the machine, or the motor to jam and possibly burn out. Never plane more than 1/8” at a time.

4.When you are satisfied the cut is properly set up, remove the workpiece from the machine. Plug in the planer, and turn the power switch ON. Allow the planer to spin up to full speed.

5.Position the workpiece on the extension roller and table so that it is level. If you are planing a long board, you may need support tables on both sides

of the planer to keep the workpiece level as its full length passes through the planer.

6.Feed the workpiece into the planer, no faster than the stated feed rate (23 feet per minute). The planer should maintain its speed. If the planer slows down noticeably, reduce the feed rate. If the planer still bogs down, remove the workpiece and adjust for a shallower cut.

7.Use a wooden pusher tool to push the board through the planer. You can also grip the finished portion of the workpiece, and pull it out of the planer.

WARNING: Keep hands farther away from intake than rollers on extensions.
