Operation The cable is put into the machine through the opening in the safety cover from above or from the front and is pushed against the sensor. This sensor starts the working cycle, which functions as follows: 1. 2. 3. 4. 5. 6. 7. SENSOR The starting position is where the Clamp Jaws (028.0010 and 028.0011) and blades are open and the Blade Head (028.0014) with sensor is in the front position. Front position is when the Blade Head is placed directly behind the Clamping Jaws CLAMP JAWS The back position is when the Blade Head is placed at the end of its way towards the Front Plate (028.0001). Insert the cable or wire into the slot of the safety cover until the end touches the Sensor (028.0035). See Figure 3-2. BLADES AND Figure 3-2 WIRE BLADE HOLDERS The Clamp Jaws will come together and then clamp and center the cable. The blades move together and cut into the insulation of the cable or wire. The complete slide, with blade head and blades, moves backwards to the adjusted removal length. At the same time, the sensor moves backwards. ADJUSTING WHEEL After the slide and the blade head have reached their final position, the clamp jaws open and then the blades. The slide moves backwards to the initial position. At the same time, a small air jet blows the stripping debris into the waste shaft (028.0028). 3.3. Adjustments 1. Cable / Wire diameter (See Figure 3-3) The adjusting wheel for the conductor diameter of the wire to be stripped, is located in the front at the top of the machine. (028.0015 for metric or 028.0083 for AWG) Figure 3-3 Note: While using die blades, the adjusting wheel has to be put in the position marked ∅ . While using prismatic blades or flat stripping blades, the adjusting wheel has to be opened wide enough. Adjust the necessary diameter step by step, until satisfactory stripping results are obtained - otherwise, there is risk that the blades will cut into the wires. The scale values on the adjusting wheel are related to the diameter of the conductor, when prismatic blades are used.

Stripping length (See Figure 3-4) The desired stripping length 1.5 – 15.0mm (.059” to .590”) is adjusted with the adjusting wheel (028.0046) on the right side of the machine in increments of 0.5mm. Note: The middle scale line is valid when using the Prismatic Blades. The front and rear scale lines are used when using the Flat Blades; The front line is used when the draft angle of the flat blade is facing out and the rear scale line is used when the draft angle of the Flat Blade is facing in (not visible) 3. Removal length / Partial stroke (See Figure 2-1) The removal length also can be adjusted as required, (from 0 – 15.0mm). This is done by using a 5mm hex wrench to adjust the screw (028.0041), located through the hole on the lower left side of the front plate. 3.4. ADJUSTING WHEEL Figure 3-4 Installing and Replacing Blades This machine will accomadate 2 different interchangable blade sets. The 63801-9200 includes the standard prismatic blades, order no. 63801-9271. There are also optional flat stripping bades available, order no. 638019272. Follow the steps below to install and replace them. Figure 3-5 63801-9271 PRISMATIC BLADES 63801-9272 FLAT STRIPPING BLADES 1. Remove the safety cover. This is done by loosening (2) knurled screws on each side of the cover and then sliding the cover forward, up and off the machine. 2. Push back the guide pin on the swing lever that is located behind each blade holder, (one side at a time) and pull out the blade from the side. See Figure 3.6. 3. Make sure that the guide slots are clean and free of debris. 4. To Install new blades, push back the guide pin and slide in the blade until the blade clicks onto the guide pin. Make sure that the guide pins catch in the corresponding holes of the blades. See Figure 3-7.

Improper adjustment or wear of the brakes can influence the function of the machine and cause faulty stripping results. The following two malfunctions are possible, due to improperly adjusted brakes: 1. The blades move together before the clamp jaws close - this means that the cable is not sufficiently clamped and centered. Correction: The brake, below the cylinder (028.6001), requires readjustment: 1. 2. 3. Unscrew the button head screw (028.8033) on the side plate (028.0002). Turn the screw, located behind the side plate (028.0002), with a 3mm hex wrench, approximately 1 to 3 turns clockwise (CW). This tightens the brake and increases the brake power. 2. The slide blade head (028.0014) with blade holder and blade moves back before the blades have moved together – this means that the insulation is removed too late or not at all. Caution: Before re-adjusting the brake always disconnect the compressed air from the machine. Correction: The brake (028.0040) requires readjustment. 1. 2. 3. 4. 5. Remove the compressed air supply from the machine. Unscrew the cover (028.5001). Turn the screw (009.8050) with a 3mm hex wrench approximately 1 to 3 turns clockwise (CW). Check the correct brake adjustment by pushing back (machine should have no compressed air) the cylinder (028.6001) manually on the unscrewed carrier . The blades will first move together. Then, the cone (028.0053) must move with its binding face against the adjusting screw (028.0036). Finally, it pulls back the complete slide (blade head 028.0014) with blade holders and the blades. In an opposite movement, the slide (blade head 028.0014) is pulled towards the front plate (028.0001). The blades first have to open before the slide (028.0014) moves.
