The Tilt-Base model allows trimming into corners inaccessible to standard trimmers. This model also allows the trimming of laminated surfaces joining at angles of 45° to 90°. This feature eliminates the need for hand-trimming in many applications. The Off-Set Base Trimmer is designed for trimming into the corner of a back splash and for trimming narrow ledges. The Underscribe Base is designed for making accurate “butt” joints in laminated plastics, phenolics and other similar materials. The Underscribe Base is used with the Model 7301 Trimmer Motor and the 43109 Trim Bit. SELECTING THE BIT These trimmers are equipped with a 1/4" diameter collet to accept laminate trimming bits having 1/4" diameter shanks. Bits are available as an accessory. 8 CARTON CONTENTS CARTON CONTENTS 1. Trimmer motor 2. Trimmer base (or bases, if a kit is purchased) 3. Wrench (or wrenches, if a kit is purchased) ASSEMBLY NOTE: This tool is shipped completely assembled. No assembly time or tools are required. OPERATION MODEL 7301 MOTOR UNIT All laminate trimmers in this manual use the Model 7301 Motor Unit. TO START AND STOP THE MOTOR The "ON/OFF" switch (A) Fig. 1 is located on the side of the unit, close to the top. To start the trimmer, move the switch down to the "ON" position. To stop the trimmer, move the switch up to the "OFF" position. Prior to starting the tool, make sure that the switch is in the "OFF" position and that the power circuit voltage is the same as that shown on the specification plate of the trimmer. A Fig. 1 Grasp trimmer firmly to resist starting torque and make sure bit is clear of workpiece and foreign objects. To avoid personal injury or damage to finished work always allow the motor to come to a COMPLETE STOP before setting trimmer down. 9 TO INSTALL THE BIT DISCONNECT THE TOOL FROM THE POWER SOURCE. 1. On Models 7310 and 7319, you can install bits either with the motor unit attached or removed. NOTE: See the instructions (Model 7312) for installing the bit in the OFFSET trimmer. See instructions (Model 7320) for installing the bit in the UNDERSCRIBE trimmer. 2. Clean and insert the shank of the bit (C) Fig. 2 into the collet until the end of the shank bottoms. Then withdraw the bit approximately 1/16". 3. Depress the spindle lock (A) Fig. 2 and rotate the collet nut (B) clockwise by hand until the lock engages the hole in the motor spindle. 4. While holding the spindle lock, use the provided wrench to tighten the collet nut (clockwise) securely. To prevent damage to the collet, do not tighten the collet without a bit inserted. TO REMOVE THE BIT DISCONNECT THE TOOL FROM THE POWER SOURCE. Do not touch the trimmer bits immediately after use. They can get very hot. 1. On Models 7310 and 7319, you can remove bits either with the motor unit attached or removed. NOTE: See the instructions (Model 7312) for installing the bit in the OFFSET trimmer. 2. Depress the spindle lock and rotate the collet nut counter-clockwise by hand until the lock engages the hole in the motor spindle. 3. While holding the spindle lock engaged, loosen the collet nut by turning it counter-clockwise with the provided wrench. 4. If the bit is tight on the collet, tap the collet nut with a wrench to release the bit. MODEL 7310 TRIMMER ASSEMBLY The Model 7310 Trimmer comes completely assembled from the factory. The base is attached to (or removed from) the motor with a base locking screw (Fig. Fig. 2 A B C 3). NOTE: The locking screw (A) Fig. 3 utilizes a spring (B) Fig. 3 and a flat washer (C). Position the spring (B) with its small end against the head of the screw (A). Attach the washer (C) after the spring. Fig. 3 A B C 10 ADJUSTING THE DEPTH OF CUT 1. Loosen the base-locking screw (A) Fig. 4) approximately 1/4 turn. 2. Turn the depth-adjusting wheel (B) Fig. 4 to reduce or increase the depth of cut. 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...
