Section 1. Tool overview This picture identifies each part/component of the #895 press tool. Parts: 1:Insert mounting screw(M6×25), 2: Press tool body, 3: Jaw hinge, 4: Connection block, 5 :Hinge pin #1 (M8), 6: Hinge pin #2 (M8), 7: Nut (M8), 8: Right handle block, 9: Left handle block, 10: Contact point on right handle, 11: Contact point on left handle, 12: Handle extensions, 13: Lock screw(M6×12), 14: Adjusting screw, 15: Connection arm, 16: Wing Nut (M8). Section 2.
Step2. Mount appropriate insert in tool A) Remove the two “Insert mounting screws” (Part No.1,M6×25). B) Position the two inserts in the press tool head, tighten with “Insert mounting screws” (Part No.1,M6×25). Note: Do not over‐tighten.
C) Press‐Force evaluation Close the press tool without a fitting or handle extensions, the appropriate Press‐Force to fully close the press tool with inserts should be about 33 pd f (pound force). If not, the press tool needs to be adjusted before use, please refer to “Step 3” for adjustment. Step 3. Press tool Adjustment A) Open the press tool and loosen the "locking screw"(Part No. 13) counter‐clockwise about 3 turns. B) To adjust Press‐Force, turn the "adjusting screw" (Part No.14.
Note: The adjustment screw (Part No. 14) does not need be touched again once the Press‐ Force reaches 33 pd f (pound force). C) Close the pressing tool and lock the setting by tightening the locking screw( Part No. 13). The adjustment is now finished. D) If handle‐extensions (Part No.12) are needed, they should not be mounted until after adjustment is completed. Handle extensions are not necessary for fittings up to 5/8”. Handle extensions are only needed for ¾” and 1” fittings. Section 4.
Section 5. Assembly of pipe and press fitting A) Start by making a square cut at the end of the tube using a suitable tubing cutter. B) Ream the tubing using the appropriate reaming tool. Insert reamer into the pipe and turn it until the inside edge of the pipe is chamfered. C) Slide the press fitting onto the pipe until you can see the tubing in the witness hole at the end of the sleeve.
Section 6. Making the press A) Position the tool jaw on the press sleeve directly up against the plastic ring/shoulder. CORRECT INCORRECT B) Complete the press by closing the press tool completely. C) The touching points (Part No. 10 and 11) must be in contact.
Section 7. Press tool wear and final rejection Over time with heavy use, the press tool components/parts will wear, affecting the Press‐Force. If the tool cannot be adjusted to reach the required Press‐Force of about 33 pd f (pound force), or the press jaws do not completely close anymore, the press tool should be discarded. This press tool has successfully gone through 5000 test cycles.
