2 M4 Underpinner Instruction Manual Introduction The Framers Corner M4 is a development from our best selling M3 Foot operated underpinner. Like the M3, the M4 is simple to operate, easy to use and has a large capacity. It shares our unique feature of the stay-locked rebate clamp which ensures that the moulding is clamped throughout the underpinning cycle. It also shares the green light which shows when the wedge is fully inserted. The M4 is a heavier machine designed for a busy workshop where, perhaps, the underpinner is operated by more than one person. For instance it has a one piece table made from 1mm thick steel which is precision ground and chromed Two new features are the mirror plate to help you see the front edge of the joint when underpinning and the LED light which has magnetic strips on the bottom, allowing it to be placed anywhere With a maximum moulding height of 7mm and a maximum moulding width of 100mm, the M4 represents the very best in foot operated underpinners available anywhere today.

3 2.Getting to know your M4 Underpinner 2.1 When you receive your M4 Underpinner i. Unbox your Underpinner and place on a flat surface. ii.wipe off any grease or oil used for protection during storage and shipment. Fit the 4 feet to the base and makesure the machine sits level on the floor 2.2 Fence Bars For safe transport the Fence has been moved along the Fence Bars. Using the allen key provided, slide the fence to the end of the bars and tighten the 2 grub screws. (photo 2)_ 2.3 Top Pressure Bar and Pressure Pads The M4 comes with a threaded Top Pressure Bar, which is locked in position by the spring loaded handle Push the handle towards the table to release and reposition the Vertical Bar. Fence Bars photo 2 Pressure Pads photo-3 Locking Lever Note that the Top Pressure Arm should be positioned accurately to give support directly over the point where the wedge is inserted into the moulding. It can be positioned using the adjutable handle (photo 4) Two Neoprene pads are supplied. One is round and the other is angled. The Neoprene prevents damage to the moulding.(photo 3) 2.4 Testing the vertical movement and green light Place a piece of moulding under the Top Pressure.The distance between the moulding and the top pressure should be for mm to 20mm. Depress the main footpedal to move the the top pressure downwards onto the moulding and then the driver upwards. When the driver is in it s top position the green light will come on.

It is equipped with a front and a rear production stop The front stop is set by the collar which is fitted to the Right Hand Fence Bar and the rear stop is set by the small diameter bar Placing wedges in to the magazine and removing The M4 will accept wedges mm, 7mm, 10mm, 12mm,and 1mm high but it is important that only Universal wedges are used. To access the wedge support , a nylon cord is attached to the end of the wedge pusher This can be pulled and looped around the screw in the corner of the table so that both hands are free for placing the wedges in the magazine.(photo 6) To set the height, turn the yellow magazine knob on the right hand side of the machine so that the pointer on the knob is pointing to the correct section of the coloured label. The knob will automatically stay in each position(photo 8) When adjusted correctly the wedges will slide underneath the Driver Support with a small gap between the top of the wedges and the cap of about 0.mm. A wedge magnet (photo7) is provided for the easy removal of the wedges from the magazine Nylon Cord photo 6 Wedge Magnet photo 7 photo Clamping Without any moulding in position, place the Front Clamp 14 on the Clamp Block There are a series of holes in the Clamp Bar to suit the width of the moulding being joined. (photo 9) Set the appropriate hole on the grub screw in the Clamp Block Depress the small footpedal on the right hand side at the front of the machine. (photo 10) This will pull back the Horizontal Clamp so that the moulding can be placed in position and aligned correctly against the fences. Taking your foot off this footpedal will allow the Horizontal Clamp to move forward until it grips the moulding securely. Horizontal Clamp Bar photo 9 Small footpedal Note that the Front Clamp 14 has 2 self adjusting jaws which take up any variation in the thickness of the moulding. 2.8 Wedge positions Wedges can be inserted anywhere along the joint face but choosing the wedge position is important. If the wedge position is too near the outside edge it will open the outside of the joint. If it is too near the inside edge then it will open the inside of the joint. The correct wedge positions are obtained by trial and error and experience. They will also depend upon the shape of the Moulding. photo 10 Page 4

5 Wedges can be inserted singly or on top each other, which is known as stacking This is particularly useful when joining high mouldings. However, when stacking wedges it is very important that the moulding does not move at all. A very small amount of movement will result in the wedges being inserted behind each other rather than on top of each other. The unique stay-locked clamp of the M4 underpinner ensures that the moulding being joined is held locked. In addition the Fence block has a locking screw (photo 11) which locks the fence bar in position for stacking,. 2.9 Production Stops Two production stops are provided on the M4 underpinner. The rear production stop, which is for the wedge inserted near the outside edge of the frame, is fence stop bar 11 2 which slides through the Left Hand Fence Block11-20 and is locked in position by the handle in the top of the Left Hand Fence Block. (photo 12) The front production stop is the fence stop collar 11-24, which slides along the Fence Bar and is locked in position on the bar by a handle (photo 12) Fence Locking Screw photo 11 Collar Stop Bar photo Foot Pedal Height Adjustment When joining small mouldings the footpedal movement can be adjusted so that it does not go all the way to its top position. The Footpedal Height Stop can be set at a height to give the required footpedal movement. This is a useful, time saving, feature when making several frames with the same height of moulding.(photo 13) 3. Maintenance Maintenance of your M4 Underpinner is essential but easy. 3.1 Adhesive build up Daily make sure that there is no glue build up around the Driver the Driver Cap and the Driver Nosepiece A spanner is provided for the removal of the Driver Cap. Use a light oil weekly in the magazine head. 3.2 Lubricate weekly Keep the top of your machine clean, a light silicon spray will help. The general machine can also be cleaned and lubricated weekly with a silicone spray to keep it looking as new. 3.3 Greasing the Cable. A little grease can be put on the cable, which operates the Horizontal Clamp, monthly. 3.4.Setting the driver height to adjust the depth of the wedge Although this is factory set, it is possible to adjust the depth that the wedge is driven into the moulding. Two locking screws are located on the Driver Push Plate 11-1.(photo 14) Loosen these and set the 2 Driver Stop bars 11-9 as required 3. Fitting a new Driver i. This is relatively simple. Undo the grub screw 11-9 in the Driver Holder The Driver can now be lifted out through the top of the magazine head. Slide the new Driver into position and lock it in the Driver Holder.(photo 1) Page Foot pedal stop photo 13 Driver Height Adjusting Bars Locking Screws photo 14 Screw for changing Driver photo 1

6 4. Setting up your M4 Underpinner 4.1 Mitre cut your 4 pieces of moulding to be joined together making sure that the angle of cut is very accurate and the cut surface is as smooth as possible. 4.2 Decide what height of wedge you are going to use and set the Yellow magazine knob to suit. (See 2.6.2) 4.3. Place one piece of moulding against the left hand fence so that the end cut is lined up with the centre of the Driver Cap Decide where you would like to insert the wedges and set the front and back production stops. (See 2.9.2) It is possible to insert wedges between these stops.(photo16) To set the Front Clamp Bar, depress the clamp foot pedal 31, put 2 pieces of moulding against the fence and set the Bar so that when the foot pedal is released, the clamp grips the moulding firmly.. Making a frame.1. Spread a quick setting adhesive on one end of a long piece and the adjoining end of short piece of moulding.2 Depress the clamp foot pedal and place the mouldings against the fences. Align the the two adjoining ends and release the small footpedal. Use the mirror plate on the fence bracket to check the alignment of the moulding,.3. Move to the front or back wedge position..4.insert the wedge by pressing the main footpedal until the green light comes on. Take your foot off the foot pedal as soon as the green light comes on. Excessive foot pressure can cause damage. Setting the Production Stops photo 16 Fence Mirror photo 17 Magnetic LED Light. Insert more wedges in the same position for high mouldings or move to the other production stop and insert the required wedges. When stacking wedges on top of each other, lock the fence by using the.6. Move to any other position and insert the required wedges..7. Release the moulding by depressing the small footpedal and repeat for the other 3 corners. photo Note Your M4 is supplied with an LED light with magnetic strips on the base. Position this light so that it shines on themoulding being joined or on the mirror plate in the centre of the fence bracket Page 6
