A copy of an EU Declaration of Conformity is enclosed with each shipment of this product. 4.0 DESCRIPTION The Enerpac model EBE22 is a fixed-head hydraulic cutter designed to cut round, square or flat metal bars and other similar items. The cutter contains two blades, one fixed and one moving. The moving blade is actuated by a hydraulic cylinder. Hydraulic force is provided by an AC powered electric motor and an internal hydraulic pump. The pump provides oil flow to the hydraulic cylinder, which advances the cylinder piston and moving blade. A hydraulic reservoir with built-in rubber diaphragm provides a constant supply of oil to the pump, regardless of tool orientation or the amount of piston extension. A trigger style on-off switch, mounted on the cutter grip, starts and stops the electric motor. The trigger must remain pressed during the cutting process. An automatic retract feature returns the piston to the fully retracted “home” position when the piston reaches its full stroke and the trigger is released. A built-in blade safety guard provides protection from splintered material during cutting and helps prevent contact with the blades. See Figure 1 for a description of cutter major features and components. Refer to Sections 2.1 through 2.4 of this manual for maximum cutting capacities, specifications and dimensions. 5.0 RECEIVING INSTRUCTIONS Visually inspect all components for shipping damage.

Using a clean rag, wipe the cutter housing, grip and motor so that these surfaces are free of oil residue. 12. Connect cutter to AC power supply. Cycle the piston several times to test for proper operation before placing the cutter back into service. 10.5.3 Changing the Oil NOTICE The oil change procedure is very detailed and will take a considerable amount of time. It should only be performed by a trained technician at an Enerpac authorized service center. Failure to properly perform the procedure may result in incomplete filling of the cutter oil reservoir, which could lead to cavitation, air entrainment, reduced performance, and pump damage. Change the oil in the cutter reservoir as described in the following steps. Refer to Figures 8A through 8E: 1. Fill a clean oil dispenser with new Enerpac HF oil. Put the dispenser aside for later use. 2. Procure a thick, soft metal bar (about 1/4 inch [6.4 mm] minimum thickness). Put the bar aside for later use. 10.5.1 Hydraulic System Maintenance Precautions NOTICE: WARNING Always disconnect cutter from AC power supply before performing hydraulic system maintenance. Failure to observe this precaution could result in accidental startup while maintenance procedures are being performed. Serious personal injury and damage to cutter may result. Wait for cutter to cool before performing hydraulic system maintenance. Hot oil can cause burns. Be sure that oil reservoir cap is securely tightened after checking oil level or changing the oil. Leaking oil can cause short circuits, fire and explosions. Additional Precautions: • Do not check oil level or change the oil in dusty areas. • Be sure that all tools (wrench, screwdriver, etc.) used to perform maintenance procedures are clean. • When adding oil and performing oil changes, take every precaution to prevent impurities from contaminating the oil or entering the cutter. Impurities can cause permanent damage to the hydraulic components. • The hydraulic reservoir contains a rubber diaphragm that slightly pressurizes the oil. Some oil spillage may occur when checking the oil level or when changing the oil. Wear and/or use appropriate personal protective equipment (PPE) to prevent exposure to hydraulic oil. • Use only new Enerpac HF hydraulic oil poured from a clean container. Use of other oil brands and/or used oil may damage the cutter and may void the Enerpac product warranty. 10.5.2 Checking Oil Level and Adding Oil NOTICE The reservoir contains a flexible rubber diaphragm that slightly pressurizes the oil. To help prevent excessive oil leakage when the reservoir cap is removed, be certain that the piston is advanced until there is a gap of about 1/8 inch [3-4 mm] between the fixed and moving blades (as described in step 1) before loosening the cap. The gap between the blades should not be less than 1/8 inch [3-4 mm]. A smaller gap may result in the piston retracting unexpectedly while the oil level is being checked. Refer to Figures 8A through 8D during the following steps: 1. Operate the cutter and advance the piston until there is a 1/8-inch [3-4 mm] gap between the fixed and moving blades (until just before the piston automatically returns). 2. Disconnect the cutter from the AC power supply to prevent accidental motor start-up during the following steps.

brittle. The bar material must be soft enough so that the bar will not break into two pieces before it is fully cut. Later in this procedure, the bar will be partially cut so that it becomes lodged in between the jaws of the cutter without being cut through completely, as the piston is extended to slightly less than maximum travel. 3. Disconnect the cutter from the AC power supply to prevent accidental motor start-up during the following steps. 4. Place the cutter in the horizontal position, on a stable and level work surface, with the oil reservoir cap facing upwards. Place a pan or suitable container under the cutter to catch any spilled oil. 5. To prevent contamination, remove any built-up dust and dirt from the oil reservoir cap, diaphragm cover, and surrounding area. NOTICE A small amount of hydraulic oil leakage may occur when the diaphragm cover is removed in the next step. Be prepared to catch this oil in a pan or with a clean rag. Dispose of spilled oil in accordance with all applicable laws and regulations. 6. Using an adjustable face spanner wrench, loosen and remove the diaphragm cover. 7. Remove the diaphragm element from the diaphragm opening. 8. Loosen and remove the oil reservoir cap. 9. Completely drain all old oil from the cutter, turning it upside down and using a suitable oil extraction system (used oil extraction pump) if necessary, so that no oil remains in the cutter reservoir. NOTICE Dispose of all used oil in accordance with all applicable regulations and laws. 10. After all oil is evacuated, position the cutter with the oil reservoir cap facing up. 11. Loosen the vent screw to provide venting. NOTICE Use only new Enerpac HF oil in the following step. Use of other oils may damage the cutter and may invalidate the Enerpac product warranty. 12. Using the oil dispenser prepared in step 1, slowly add new Enerpac HF oil through the oil drain/fill hole and diaphragm opening until oil level is up to the top of the drain/fill hole. 13. Install and securely tighten the oil reservoir cap. Leave the diaphragm element and diaphragm cover removed. NOTICE: WARNING To avoid serious personal injury, stay clear of cutting head and blades during the following procedures. Wear rubber gloves to prevent contact with oil. Wear eye and face protection to avoid injury due to splashing oil. 14. Connect the cutter to the AC power supply. 15. Cover the diaphragm opening with a rubber-gloved hand to help prevent oil splashing. 16. Prime the pump by pressing and releasing the trigger in short bursts. During this process, check the oil level in the diaphragm opening and add oil (as needed) to keep the reservoir filled. Failure to keep reservoir full may result in cavitation and pump failure. Pump is primed when piston starts extending. NOTICE During priming, the oil may become entrained with air and may develop a foamy appearance. This is normal. 17. Continue pressing and releasing the trigger in short bursts as the piston extends. During this process, do not add oil, but verify that the pump has ample oil supply. Continue until piston is extended to approximately half stroke. NOTICE During the following steps, refer to Figure 4 for piston release screw details. 18. While covering the diaphragm opening with a rubber-gloved hand, retract the piston gently by slowly loosening the piston release screw. 19. Tighten the piston release screw. 20. Place the soft metal bar (refer to step 2) into the cutting head. 21. Press and release the trigger in short bursts until the piston is extended as far as possible, but before it makes a full cut and retracts. The moving blade will become lodged in the bar, preventing the piston from retracting. This procedure is necessary because the cutter mechanism alone may fail to hold the piston in the partially extended position as oil is being added in the following steps. NOTICE If you cut completely through the bar, try again, cutting as far as you can without making a full cut. 22. Disconnect the cutter from the AC power supply to prevent accidental motor start-up during the following steps. 23. Add oil through the diaphragm opening until the bladder opening is nearly full. 24. Slowly install the diaphragm element in the diaphragm opening. This should result in some oil leakage from the vent screw, as well as from around the diaphragm element. 25. Tighten the vent screw. 26. Install and securely tighten the diaphragm cover. 27. Loosen the piston release screw to retract the piston. If piston is stuck, use the bar to manually push the piston back until it retracts. 28. Remove the soft metal bar from the cutting head. Do not discard the bar. It will be used again later in this procedure. 29. Tighten the piston release screw. 30. Connect the cutter to the AC power supply.

NOTICE: WARNING • Always disconnect cutter from AC power supply before beginning blade replacement procedures. Failure to observe this precaution could result in accidental startup during blade replacement. Serious personal injury could result. • Use extreme caution when removing and installing blades. Blades may be sharp even when worn. To avoid hand injury, wear appropriate personal protective equipment (PPE) and avoid contact with blade cutting edges. 10.6.1 Blade Wear The use of worn blades decreases the effectiveness of the cutter and can also side load the cylinder, resulting in possible damage to the tool. Motor overheating can also occur. Replace blades immediately if they are worn and/or damaged or if there has been a noticeable decrease in cutting performance. NOTICE Blades are not sharpenable and must be replaced when worn. To help ensure optimum cutting performance, replace both the fixed blade and the moving blade at the same time. NOTICE: WARNING To avoid serious personal injury, stay clear of cutting head and blades during the following procedures. 31. Start the cutter and cycle the piston through several advance and return strokes. Ensure that piston is fully retracted when done. 32. Be sure cutter is positioned so that the oil reservoir cap is facing upwards. Do not operate cutter for several hours (preferably overnight) to allow any remaining air to separate from the oil. 33. Place the soft metal bar (refer to step 2) into the cutting head. 34. Press and release the trigger in short bursts until the piston is extended as far as possible, but before it makes a full cut and retracts. The moving blade will become lodged in the bar, preventing the piston from retracting. This procedure is necessary because the cutter mechanism alone may fail to hold the piston in the partially extended position as oil level is being checked in step 35. NOTICE If you cut completely through the bar, try again, cutting as far as you can without making a full cut. 35. Disconnect the cutter from the AC power supply to prevent accidental motor start-up during the following steps. 36. Loosen and remove the oil reservoir cap. Recheck the oil level in the oil drain/fill hole. If oil level has dropped, loosen vent screw and add additional Enerpac HF oil until the oil level is up to the top of the hole. 37. Install and securely tighten the oil reservoir cap. 38. Tighten the vent screw (if loosened). 39. Using a clean rag, wipe the cutter housing, grip and motor so that surfaces are free of oil residue. 40. Connect the cutter to the AC power supply. Cycle the piston several times to test for proper operation before placing the cutter back into service.
