3. Tighten the base-locking screw securely. Make a test cut in scrap material to check the depth of cut. 4. Repeat steps 1 through 3 until the desired depth of cut is achieved. A B Fig. 4 ADJUSTING THE SUB-BASE ALIGNMENT Applications using a template guide require the bit to be centered within the guide, and the center hole in the sub-base to be in line with the collet of the motor unit. Your model has an adjustable sub-base. To adjust: 1. Install the 42054 Template Guide (available as an accessory) on the sub-base and tighten securely. 2. Loosen the sub-base mounting screws just enough to allow the sub-base to move on the base. 3. Install a straight 1/4" diameter bit in the collet of the motor unit and tighten securely. 4. Attach the motor unit to the base. Align the hole in the template guide with the bit and adjust the depth of cut so that the bit extends through the template guide. Tighten the motor unit in the base. 5. Tighten the sub-base mounting screws securely. THE OPTIONAL 73100 EDGE GUIDE KIT The optional Model 73100 Edge Guide Kit is available for use with the Model 7310 trimmer. This kit is designed for use with non-piloted bits on curved or straight applications. Non-piloted bits can produce a 90° straight cut, a 10° bevel cut, or a 22° bevel cut. The kit (Fig. 5) contains: A. Base and roller guide - for flush or bevel trimming B. Edge guide – for flush trimming C. Edge guide – for bevel trimming D. Straight edge guide – for straight trimming E. Guide setting gauge F. Mounting screws G. Wrench Fig. 5 A B C D E F G 11 ATTACHING AND ADJUSTING THE BASE AND THE ROLLER GUIDE 1. Remove the power unit from the base unit (see “TO INSTALL BIT”). 2. Install the bit. 3. The base and roller guide (A) Fig. 5 is assembled at the factory. To install, remove a sub-base mounting screw (A) Fig. 6 and insert the alignment pin (in the guide base) into the hole (C) in the bottom of the trimmer sub-base. Fasten with two mounting screws (F) Fig. 5 and (C) Fig. 7. Hand tighten for further adjustment. 4. Install the bit (See “TO INSTALL THE BIT.”). Then, install the motor to base and adjust the depth of cut (See “ADJUSTING DEPTH OF CUT”). 5. Align the roller guide with the bit by loosening the locking screw (A) Fig. 7 and turning the adjusting screw (B) with the provided hex wrench until the guide is in the desired location. Fig. 6 CA AB C Fig. 7 FLUSH TRIMMING 1. Attach the base and guide to the trimmer as outlined in "ATTACHING AND ADJUSTING THE BASE AND ROLLER". 2. Remove the roller guide and replace it with the flush trimming guide (B) Fig. 4. Identify this guide by the molded letter “F”. Make sure that the stud on the end of this guide faces the trimmer base. 3. Install the guide setting gauge (E) Fig. 4 in the trimmer collet (see "TO INSTALL THE BIT"). Install the trimmer motor to the base. Adjust the guide so that hole in the end of the gauge is positioned over the guide stud. 4. Remove the guide setting gauge from the trimmer and install a flush trimming bit. 5. Adjust the depth of cut so that the straight portion of the bit extends below the trimmer base at least the thickness of the workpiece. 6. Make a trial cut on scrap material. BEVEL TRIMMING 1. Follow Steps 1 through 5 under "FLUSH TRIMMING", except install the bevel trimming guide (C) Fig. 4. This guide is identified by the molded letter “B”. 2. Adjust the depth of cut so that only the bevel portion of the bit extends below the trimmer base at least the thickness of the material to be trimmed. 3. Make a trial cut on scrap material to check alignment. 12 USING STRAIGHT EDGE GUIDE You can use the straight edge guide (D) Fig. 5 with either bit for trimming straight edges. Attach it to the guide base and adjust similar to the other guides. MODEL 7319 TILT BASE TRIMMER ASSEMBLY Model 7319 Tilt Base Trimmer is completely attached at the factory. You can remove the base from the Model 7301 motor with a base locking screw (A) Fig. 8. NOTE: A flat washer (B) Fig. 8 is on the locking screw. Model 7319 Tilt Base is designed for use with 43216PC flush trim bit for trimming into corners. You may also use it with other “self pilot” trim bits for conventional trimming at 90° setting. Fig. 8 A B ADJUSTING THE DEPTH OF CUT DISCONNECT THE TOOL FROM THE POWER SOURCE! Loosen the base locking screw and move the motor unit up or down to decrease or increase the depth-of-cut. You may have to slightly withdraw some bits in the collet to obtain a maximum depth of cut. When you withdraw a bit, be certain that at least 1/2" of the bit shank is engaged in the collet. Do not use bits that result in having less than 1/2" of the bit shank engaged in the collet. To do so may cause poor gripping of the collet, resulting in a loose bit. If the bit comes out of the collet, it could cause damage to the workpiece and/or personal injury. ADJUSTING THE TILT 1. Loosen two tilt locking screws (C) Fig. 9 (one on each side of base) using the provided wrench. 2. Match the base-aligning index mar...
