Dake strongly recommends that Dake press users obtain a copy of the current American National Standard Institute (ANSI) B11.2 standard, for a more complete understanding of their responsibilities. ANSI B11.2 states the following, relative to point of operation safeguarding: "Normally, only the employer (press user) can determine the requirements of the press productions system components, including the dies and methods for feeding. Therefore, the employer is ultimately responsible to designate and provide the point-of-operation safeguarding system." The standard also discusses additional responsibilities of the employer. Some of the key responsibilities are: · The employer is responsible for the safety, use, and care of the hydraulic power press production system. · The employer is responsible to consider the sources of hazards for all tasks to be implemented on the hydraulic power press production system. · The employer is required to eliminate, or control identified hazards in the scope of their work activity. · The employer is responsible for the training of personnel, caring for, inspecting, maintaining, and operating hydraulic press production systems to ensure their competence. · The employer is responsible to provide and ensure that point-of-operation safeguarding is used, checked, maintained, and where applicable, adjusted on every production operation performed on a press production system. A complete and current copy of the ANSI B.11.2 standard can be obtained by contacting the following: American National Standards Institute 1430 Broadway New York, NY 10018 AMT The Association for Manufacturing Technology 7901 Westpark Drive McLean, VA 22102 5 REV062022 SPECIFICATIONS Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com Number Capacity Width between uprights Width between table channels Minimum ram to table Maximum ram to table Ram travel Horizontal work head travel Height Weight Base Ram advance speed Pressing speed Number or pumps Air pressure Model 6-275 906275 75 tons 44" 8-1/4" 6" 36" 10" 24-5/8" 86" 1,500 lbs 55" x 36" 45 ipm 2 ipm 1 90-125 psi Model 6-475 906475 75 tons 44" 8/1/4" 6" 36" 10" 24-5/8" 86" 1,550 lbs 55" x36" 40 ipm 3-1/2 ipm 2 90-125 psi In the space provided record the serial number and model number of the machine.

Assemble these parts in the following order: 1. Bolt the base angles to uprights using four provided bolts and nuts. Ensure that the base angles are against the stops on the uprights. The press should set on a level floor with base angles touching the floor at all points, use shims when necessary. 2. Connect airline in to street elbow (Item 136) at the right side of the control block. Avoid restrictions in air supply line to ensure ampler air to the air motor. For maximum performance the air supply line should be 1/2" pipe if the distance from the compressor to the press is 0-30 feet, 3/4" line for 30-60 feet, and 1" if distance is greater then 60 feet. WARNING: AIR MUST BE MOISTURE FREE. WATER IN THE AIR LINE COULD CORRODE PRESS BEYOND REPAIR. 3. Oil Requirements: Fill the reservoir with Mobil DTE 24 or equivalent oil through the pipeline in back of the press at pipe coupling by removing the pipe plug. Make sure the air source is removed from the reservoir prior to removing the plug. Oil level may be checked, with the ram up, by removing the pipe plug on the right side of the reservoir near the front. Replace plug before operating the press. Model 6-275 & 6-475, 75-ton presses use 10 quarts. 4. Attach nose piece to ram by inserting shank into ram and tightening the set screw. 5. Place the hoist crank on the lift drum shaft. Turn the hoist crank to relieve the pressure on the table pins. Keeping tension on the hoist crank, remove the table pins one at a time. a. After removing the table pins turn the crank running the table channels from top to bottom. Check to make sure the cable is tracking correctly. The cable should be on each of the two upper pulleys and should track back and forth on the cable drum. Always place table pins under the table channels before releasing the hoist crank when positioning the table channels for cable tracking, servicing, or set-up for desired work opening. b. If a tracking problem exists contact Dake for instructions. Be sure all table pins are fully inserted in place before applying pressure. Always remove or release pressure on the cable before pressure is applied. 8 REV062022 OPERATION Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com WARNING DO NOT OVERSTROKE THE RAM. Over-stroking will cause premature seal failure. Models 6-275, and 6-475 have a 10-inch stroke. The press has been completely tested at the factory and after setting up according to this manual the press is ready for operation. However it is necessary for the operator to acquaint themselves with the controls. 1. Three screws (Item 109) are used to lock the workhead in desired position along the head channels. 2. The handcrank is to raise and lower the work table channels to proper work height. When desired height is obtained insert the table pins. Models 6-275, and 6-475 use 2 pins on each side, 4 total. Be sure all table pins are in place and in as far as they can go before pressure is applied. Be sure to slack off the cable before pressure is applied. See step 5 of the "SET UP" in this manual. 3. The handle on the left side of the control block (Item 76) opens and closes the ball valve which releases the ram pressure. This valve should be kept firmly closed and opened only when it is desired to return the ram to its up position. 4. The two table plates and two V-blocks are used for supporting the work in process. 5. The control knob (Item 103) on the right side of the panel regulates the speed of ram travel. The knob will return to the off position when released. 6. The relief valve (Item 90) had been set at factory to open at maximum tonnage of the press. The valve can be adjusted by removing the hex nut located on the top of the valve block at the right front of the reservoir and turning the adjusting screw to the left for a lower setting. PRESS. WARNING: NEVER EXCEED THE RATED TONNAGE OF THE MAINTENANCE Recommended to replace hydraulic oil every 6 months of machine use. See step 3 in "SET UP" section for instructions. LUBRICATION · Keep all working parts of the press well-oiled for easier operation. · Keep a light film of oil over the entire surface of the ram to prevent rust. · Regularly clean off work surfaces and the surrounding work area. 9 REV062022 Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com TROUBLESHOOTING 1. If the press loses pressure: a. Check all tubing joins for leaks and tighten tube nuts. b. Drain reservoir and remove packing nut (Item 75), valve rod (Item 73), and ball valve (Item 73). Clean out valve seat and reseat ball valve using a brass rod as a drift, striking sharply with a hammer. Reassemble valve rod, packing, and packing nut. Refill reservoir with appropriate oil amount. c. Leakage past educator inlet check ball (Item 69). Drain reservoir, remove large pipe plug (Item 71), valve seat (Item 70), and check ball (Item 69). Clean and inspect seat. Reset ball on seat or replace seat with new part if necessary. Reassemble with ball above the seat tightening plugs. d. Worn leather cup or T-ring seal. If none of the previous conditions seem to have been the cause, the leather cup or T-ring may be worm or damaged. To inspect, drain oil and remove the work head from the press frame. Remove tube assembly (Item 144). Set two 4x4 blocks on the table then raise the table channels with the block up to the bottom of the reservoir applying pressure to the reservoir. Remove roller brackets from the reservoir and lower the work head using the table. WARNING: Be sure the stroke indicator rod support is installed in the side of the piston. If not, insert 1/2"-13 stud or cap screw into the tapped hole in the piston. This will hold the piston down under spring pressure. e. Next remove nuts from cylinder flange and lift cylinder off piston. The piston leather or T-ring seal can now be inspected and replaced if necessary. Press may be reassembled in reverse order being careful not to damage the lip of the leather cup or T-ring seal as it enters the cylinder. Note: A leather cup will only in presses made before 1992 or has a serial number before 192522. 2. Press will not develop rated tonnage. a. Dirt under ball valves. Refer to 1 c above. b. Worn leather cup or T-ring seal. See 1 d above. c. Relief valve is not set properly. This valve is located on the top side near the right end of the control block at the front of the reservoir. The valve is set at the factory to bypass oil from the pump back to the reservoir when the press reaches its rated capacity. The load on the spring (Item 91), which governs the pressure at which the valve will bypass oil, is adjusted by turning the screw (Item 90) in to increase pressure or out to decrease pressure. Replace seal (Item 89) and cap nut (Item 88). Note: We advise that the relief valve not be tampered with after it is once set at the capacity of the press. 10 REV062022 Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com 3. Nothing happens when the press is operated. a. Release valve is open. Be sure the release valve is firmly closed when pressing. b. If the ram will come down only a fraction of its rated stroke check the oil level in the reservoir with the ram at the top of its stroke. It should be visible in the sight window at the side of the reservoir. 4. Press is operating slow. a. Check the air supply line for restrictions to determine if air motors are getting ample supply of air. b. Release valve not closed properly. Release valve must be firmly closed when using the press. c. Wrong hydraulic fluid. After considerable research and tests made with the cooperation of the pump manufacturer it is recommended that Mobil DTE 24 oil or equivalent is used. 5. Oil is coming out if the air vent. a. Drain out the spring chamber by removing the 1/8" pipe plug which is put in the hub or boss that contains the oil seal where the ram extends out of the reservoir. Once oil is drained, run the press up to full tonnage with pipe plug still removed. Excessive oil is a sign that the head seal has been damaged. Refer to troubleshooting reference 1 d. to replace seal then replace pipe plug. 6. Excessive leakage around the ram. a. Drain out the spring chamber as instructed above. A small amount of oil in this chamber facilitates lubricating the bushing the ram passes through and prevents scoring. However if operation performed on the press is spoiled due to the slight leakage of oil, remove the pipe plug as described above and connect tube line to continually drain this chamber. 11 REV062022 EXPLODED VIEW & PARTS LIST Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com 12 REV062022 Item 1 2 2* 3 4 6 7 8 8* 9 10 11 12 13 14 15 15* 16 16* 17 18 19 25 26 - Part Description Pulley Frame Spacer Hex Cap Screw (1/2"-13 x10") Name Plate Table Plate V-Blocks Table Spacer Assembly Hex Cap Screw (5/8"-11 x 10-1/2") Table Channel Lock Washer (5/8") Hex Nut (5/8"-11) Table Pin Base Angle Hex Head Bolt (1/2-13 x 1-1/4") Lock Washer (1/2") Lock Washer (1/2") Hex Nut (1/2"-13) Hex Nut (1/2"-13) Cable (Ø 3/16") Cable Clamps Table Hoist Assembly Hex Cap Screw (43335 Hex Nut (3/8"-16) Workhead Assembly - Single Pump Workhead Assembly Double Pump Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com Part No. Qty 727 2 706943 1 997 2 43361 2 81003 1 702A 1 336 2 716788 4 79983 4 706945 2 43648 2 43917 2 569 6 566 2 43349 4 43647 2 43647 4 43916 2 43916 4 726 1 991 4 701677-S 1 43335 2 43912 2 906276-S 906476-S 13 REV062022 TABLE HOIST ASSEMBLY 701677-S Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com Item 19 20 21A 21B 22 23 24 27 28 29 30 Part Description Hoist Crank Assembly Worm Shaft Retaining Ring Retaining Ring Worm Key Worm Hoist Frame Drum Shaft Drum Key Worm Gear Cable Drum Part No. Qty 701653A 1 7530 1 43978 2 27437 2 47364 1 385 1 725 1 724P 1 737 1 736 1 723 1 14 REV062022 POWER UNIT ASSEMBLY Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com Item 37 39 45 46 47 48 49 50 51 52 55 66 67 - Part Description Hex Nut (1/2"-13) Cylinder Gasket Packing Ring Cylinder Piston Assembly Serial No. > 192552 Ram Spring (Small) Spring Spacer Ram Spring (Larger) Wear Ring Oil Seal Self-Tapping Screw (#10-24 x 3/8") (Not Shown) Reservoir Assembly Pipe Plug Piston Guide Cylinder Repair Kit (Items 39, 45, 52, 53, 72, 74, 89, 93, & 97) 15 Part No. Qty 43916 4 9777 1 17942 1 2213 1 716227 1 2231 1 2233 1 2232 1 76807 1 6021 1 43881 4 716784 1 589 1 87112 1 1 REV062022 Dake Corporation 1809 Industrial Park Dr Grand Haven, MI 49417 www.dakecorp.com * For presses with serial numbers lower than 192522 or made before 1992 refer to this exploded view and parts list for accurate part information.
