Connecting a Dust Extraction Hose

NOTE: This tool is fitted with an outlet (73 - 76) for attaching to a dust collection system (not included).

1.Insert the hose from your dust collection system (not included) into Connection Cap (76) and turn the Connection Cap clockwise to form a compression seal on your hose.

NOTE: This fitting works with standard sized 2-1/2” dust collection hoses. Your system may vary.

CAUTION: It is highly recommended that you use some type of dust collection system, since operation of this tool creates considerable dust and debris.

WARNING: Always wear ANSI approved face shield and dust mask when fine airborne particles of crystalline silica. Silicosis is a disabling and

sometimes fatal lung disease caused by the inhalation of fine airborne particles of crystalline silica. Silicosis is caused by the inhalation of small particles of crystalline free silica dust. Quartz, as found in sand or concrete, is the most common source of silicosis. Always wear a fine dust filtration mask when working around sand, cement and other sources of airborne crystalline free silica.

Operation

NOTE: Always mark out the channels you intend to cut before beginning work. Measuring and marking tools are available from Harbor Freight Tools.

1.Connect the tool to an appropriate power source, and check to ensure that it is safe to begin work.

2.Position the tool slightly above your cut mark, and place the leading edge of the Height Adjuster (58) on the work material. Hold the Handle up, so that the cutting blades do not contact the work material. Press the Switch (30) to turn ON the machine.

NOTE: This tool has a safety power switch. You must first press the locking button forward before squeezing the power switch on.

3.Slowly rotate the tool downward to “plunge” the cutting blades into the work material. Hold the tool securely as it will want to pull away from the operator while in use.

4.Once the Height Adjuster (58) is flush on the surface of the work material, pull the tool downward along your cut line.

WARNING: This tool is designed to be pulled against the rotation of the blades, toward the handle end of the tool, when in use. Do not push the tool forward when cutting.

5.Continue to cut at a steady pace. Pay attention to the sound of the tool. If the motor speed slows appreciably or is erratic, slow down your cutting rate. If the motor speed remains high, you can increase your cutting rate.

WARNING: If the blades stop in mid-cut, release the trigger IMMEDIATELY. Holding the trigger while the blades are stuck can cause permanent damage to the tool or the workpiece. Unplug the tool and then pull the blades out of the cut. Check both blades carefully for damage and allow the motor to cool fully before proceeding. Use less pressure and cut more slowly while continuing; this problem can usually be prevented by cutting at the proper pace.

CAUTION: If the motor becomes overheated, a thermal safety cut out switch may engage, stopping the tool. If you notice the tool heating up, stop work for a few minutes to allow the tool to cool. When you continue work, use a slower cutting rate.
