5. Align the two holes in the underscribe attachment (G) Fig. 18 with the two holes in the base (A). 6. Attach the underscribe attachment (G) Fig. 19 to the base (A) with two screws and an eccentric washer. E D C G B A Fig. 18 Fig. 19 TYPICAL APPLICATIONS TRIMMING 3/4 IN-AND-OUT TRIMMING SCRIBING OF VERTICAL BACKSPLASH OF INSTALLED CORNER BACKSPLASH TO WALL APPLICATION – Trimming front edge of 3/4" vertical backsplash. This is an operation standard trimmers with round or square bases are unable to do without the use of a special bit. Self-piloted bit guides trimmer for one-pass trimming every time. Triangular base enables trimming with backsplash in place. APPLICATION – Trimming into and out of installed backsplash corner with little or no hand trimming required. Triangular base enables complete corner trimming with backsplash in place. APPLICATION – Accurately scribing the back side of a preassembled panel or post-formed backsplash. Once the lip is accurately scribed, the trimmed portion is then pushed against the wall and mated exactly. Self-piloted bit follows every trimmer movement to create exact reproduction of wall surface in one pass! Front edge of trimmer is guided against wall. Maintain 3/4" separation from wall for scribing. OPERATION – Trimming 3/4" backsplash OPERATION – The new Porter-Cable OPERATION – The guide assembly must with the new Porter-Cable Offset Laminate Offset Trimmer will trim into and out be removed. Using the self-piloted bit, Trimmer fitted with a solid carbide self- of 90° corners with ease using self- the Porter-Cable Offset Trimmer scribes piloted bit. piloted bit. accurately to the wall surface. 17 Trims odd angled corners less than or greater than 90°. Trims up to vertical surfaces. ADJUSTING THE BIT EXPOSURE DISCONNECT THE TOOL FROM THE POWER SOURCE. 1. Loosen the base locking screw (E) Fig. 20 approximately 1/4 turn. 2. Turn the depth-adjusting wheel (D) Fig. 20 counter-clockwise (looking at top of wheel) to lower the bit until it touches the guide plate. 3. Firmly tighten the locking screw (E). E D Fig. 20 ADJUSTING GUIDE PLATE The Underscribe Trimmer Base is equipped with an adjustable guide plate (Fig. 21). Adjust the guide plate by rotating the eccentric, using the special wrench that is supplied with the Trimmer Base. To adjust the guide: 1. Make a trial cut using scrap material and check the fit. DISCONNECT THE TOOL FROM THE POWER SOURCE. 2. Turn the eccentric to correct fit. NOTE: If the joint is too loose (with a crack between the two pieces of laminate), turn the eccentric clockwise. If joint to too tight so that the laminate will not snap into place, turn the eccentric counter-clockwise. 3. Repeat Steps 1 through 3 as required to achieve a good fit. Fig. 21 USING THE UNDERSCRIBE TRIMMER The bottom plate of the Underscribe Trimmer has a guide lip (Fig. 22). This guide lip is moved along an installed piece of laminate as the trimmer bit cuts the mating piece of laminate. 18 The “butt” joint is commonly used in the construction of face frames. To install a laminate covering on a face frame: Always wear safety glasses while operating a laminate trimmer. A Trimmer Base B Sub-Base C Installed laminate D Guide Lip E Bit F Laminate A B C E F D Fig. 22 1. Cut the pieces of laminate covering to rough size. Apply contact cement to the face frame and the laminate pieces in the normal manner. NOTE: Cut the rail covering approximately 1" longer than the rail (to allow material for trimming). 2. Apply the laminate to all stiles. 3. Position the laminate to a rail with at least 1/4", and no more than 3/4", overlapping each stile (see Fig. 23). Use a roller to secure the center section of the laminate to the rail. Leave at least 4" of the laminate loose, at both ends of the rail (Do not roll it down). 4. Securely clamp the face frame assembly to the worktable to prevent movement during the trimming operation. 5. Position the underscribe trimmer onto the face frame so that the top (see Fig. 24), is against the edge of the stile. NOTE: The trimmer should be to the right of the rail, so that the cutting action will move from right to left (see Fig. 24). NOTE: The finished cut is illustrated in Fig.25. Fig. 23 Fig. 24 Fig. 25 19 6. Verify that the bit is clear of foreign objects and that the cord will not get caught on any obstructions. 7. Grasp the motor firmly to resist starting torque and move the switch button to the "ON" position. 8. Allow the motor to reach full-speed. Feed the trimmer from right to left with a smooth steady motion. NOTE: The tapered edge of the underscribe base will slide underneath the rail covering, lifting the laminate into the cutter. 9. After completing the cut, move the switch button to the "OFF" position and allow the motor to come to a complete stop before putting the trimmer down. 10. Press the rail end into position and roll down. 11. Repeat this process as necessary to complete the face frame. TROUBLESHOOTING For assistance with your tool, visit...
