2. Means of operation

2.1 Using methods

① When the power line is connected to the 110V/220V power source, the power indicator light shines, meaning the machine is ready for operation and normal work can proceed. ② The spacing of the fixed idler wheel, the movable idler wheel, and the steel bar block needs to be adjusted accordingly based on the specification of the steel bar. ③ Connecting the foot switch to point 1 or point 2 will make work more convenient.

Point 1: Connect to work. The angle is set by point 1. Press the START button or the point 1 foot pedal switch to control operation.

Point 1: Connect to work. The angle is set by point 1. Press the START button or the point 1 foot pedal switch to control operation.

Point 2: Connect to work. The angle is set by point 2, and operation is controlled via the foot switch. In this case, the angle set by the point 1 handle must be set to the same level angle as point 2 or greater than point 1. Also, after setting the angle handle, ensure the handle nut is tightened, as it may become loose during machine operation.

④ Adjust the angle you need by moving left or right. When the adjustment is set accurately, ensure that the angle setting handle is fixed. ⑤ The operator must stand outside the direction of the rebar bender's operation. ⑥ When pressing the start switch or the foot switch, the machine will bend the right angle you have set. ⑦ If you find any abnormality during operation, you must press the emergency stop to shut down the machine's operation. ⑧ Remember, when bending, the angle of point 1 must be larger than point 2, otherwise the machine cannot operate normally. (This applies to RB-25 and RBC-25; RB-32 and RBC-32 have no such issue.) ⑨ When using the foot switch to control the machine's operation, if it becomes uncontrollable, press the hand switch near the power light to test whether the motor rotates, to determine if the foot switch is faulty.

Note: ① When the emergency switch is pressed to run the machine, the idler wheel will return to its position.

② Under the working condition of point 2 bending, the point 1 handle must be kept at the same level angle as point 2, or set to an angle 5 degrees smaller than point 1, and then fix the angle handle. This is to prevent electrical or machine misoperation.

2.2 Attention items

① Must use according to the contemporary bending capacity; exceeding this capacity can easily cause product breakdown. ② When performing steel bar bending work, pay special attention to avoid safety incidents such as finger injuries. ③ Depending on the hardness of the reinforced material, special attention should be paid to avoid fragments that may lead to safety incidents such as wounds. ④ Do not operate until you confirm that no person or object is within the reinforced bending radius. ⑤ The product is electric functional machinery. If exposed to rain or water, it may cause leakage; it must be covered with a waterproof membrane during use. ⑥ Ensure the stationary ring bolt is fixed when transporting or moving the machine. ⑦ When operating under point 2, fix the angle of point 2 to be the same as or no more than 5 degrees from point 1, to ensure that under conditions of external shock, the machine itself will not move left and right to stop the machine. ⑧ Make sure the stationary ring bolt is fixed when transporting or moving the bender. Chains must be inserted into the safety pin to prevent the bender from shaking or waving during transport. When moving the bender by fixing the handle, the 4 bolts must not be loose, then move the bender together by 4 handles. ⑨ Prohibit the use of idler wheel items.

If you operate according to the method marked with (X) below, the troughing of the hoop will burst easily. Record the proper operation sincerely!

Foot switch 1: Press foot switch 1 to perform the operation set by the "1 point" angle adjuster. 4. Foot switch 2: Press foot switch 2 to perform the operation set by the "2 point" angle adjuster. 5. Emergency stop switch: During operation, if any problem occurs, release the button to stop all actions. 6. Angle 1: Adjust the bending angle using the "1 point" adjuster (corresponding to foot switch 1). 7. Angle 2: Adjust the bending angle using the "2 point" adjuster (corresponding to foot switch 2). 8. Before bending, note that the angle setting of "1 point" must be greater than that of "2 point", otherwise the machine will not work. This applies to RB-2 and RBC-25; RB-32 and RBC-32 have no such issue.

4.5 Operating process

1. Connect the power cord to a 110V/220V outlet and check that the indicator light turns on. This means the bender is ready to work. 2. Choose the correct size of fixed idler wheel and idler wheel according to the rebar diameter. 3. Connect the foot switches to the 1-point and 2-point holes securely. 4. The 1-point angle setting adjuster is for setting the angle for the foot switch connected to the 1-point hole. For example, to bend 180 degrees with foot switch 1, set the angle to 180 degrees using the 1-point adjuster, then press foot switch 1 to bend the rebar 180 degrees. 5. The 2-point angle setting adjuster is for setting the angle for the foot switch connected to the 2-point hole. For example, to bend 90 degrees with foot switch 2, set the angle to 90 degrees using the 2-point adjuster, then press foot switch 2 to bend the rebar 90 degrees.

6. Note that the angle setting of "1 point" must be greater than that of "2 point", otherwise the machine will not work. See the two pictures below. 7. Adjust the angle adjuster by moving it left or right as needed. 8. The operator should stand on the outside of the rebar's bending direction. 9. The rebar will be bent to the set angle when the start switch or foot switch is pressed.

Attention: For precise work, set point 1 when the bending angle is large (90°), and set point 2 when the bending angle is small (135°).

Note:

① It is mandatory to follow the processing capacity while using the product, as the product can easily lead to failure. ② When gripping, bending, or reinforcing material, pay special attention to safety incidents such as bumping fingers. ③ According to the different hardness of the reinforced material, special attention should be paid to the fracture which may lead to safety incidents such as wounding. ④ Please do not operate until you confirm no person or object is in the reinforced bending radius. ⑤ The product is electrical functioning machinery. If it is exposed to rain or water leading to leakage, it must be covered with a waterproof membrane after use.

4.6 Movement

1. Move the bender after making sure the handle fixing bolt is tight.
2. Make sure the stationary ring bolt is fixed when in transit or moving the bender.
3. Chains must be inserted into the safety pin to prevent the bender from shaking or waving during transit.

In cold weather, warm up the unit for 30-60 seconds so that the hydraulic fluid reaches the proper viscosity. Pull the trigger switch to extend the piston and release it when it has reached its full stroke. Repeat 15-20 times.

Stopper adjustment

The adjustable stopper function is to maintain the rebar in the correct position during cutting and must be properly set for each size of rebar before

making a cut.

Screw in stopper to provide sufficient clearance for rebar.

Insert rebar fully into U-shaped support. Make sure that rebar is resting against the base of the stopper.

Keeping rebar at right angles (90°) to front cutter block, screw out stopper until it is just touching the rebar. Once set, the stopper needs no further adjustment while cutting rebar of the same diameter, but must be re-adjusted for a different size rebar.

Caution: Failure to correctly set the stopper will result in excessive wear on cutter block and may cause cut end to fly out.

Cutting

1. Insert rebar between stopper and front cutter block, making sure that it is properly seated in U-shaped support.
2. Pull trigger switch and keep depressed while piston advances and cut is made. (If switch is released at an intermediate point, piston will stop.)
3. When cut is completed, release switch. Piston retracts automatically.

(Note that switch can't be re-activated until piston has fully retracted.)

Points of attention

1. Be especially careful when cutting off short lengths (30cm or less) cut end tends to fly out.

Caution: Flying ends are a hazard to all personnel in the vicinity. Use safety screens.

1. Do not cover air vents.

Caution: If vents are covered, the motor will overheat and may burn out.

1. If hydraulic oil exceeds 70°C (158°F), power will drop. Allow it to cool before resuming operation. (Be particularly careful in summer, when the aluminum pump case heats up quicker.)
2. If a drop in power is observed and the motor is unusually hot, check the brush.
3. If the piston should ever fail to retract completely, push the rear cutter block backwards to manually retract the piston.

Caution: Use a rebar or flat metal bar for this purpose. Never push the block with any part of the hand, even if gloved.

Once the piston has been retracted, pull the trigger switch long enough to advance the piston. Unplug the unit. Check the piston and housing for accumulated dust or iron filings that may be jamming the piston. After cleaning, if the piston still does not automatically retract when fully extended, the piston itself may be damaged. Return the unit to an authorized agent for repair.

Maintenance

Cutter blocks

Before using, always check that the two bolts on each cutter block are properly tightened. Using a loose block will result in damage to the block housing. Also check the condition of the cutter blocks. If either cutting edge is worn or chipped, remove the retaining bolts and rotate both blocks so that two edges come into use. Replace and tighten the bolts (each block has four cutting edges).

When all four cutting edges have been used, or if either block is cracked or otherwise damaged, replace both blocks.

Caution: A loose or cracked block may result in injury to the operator.

Cleaning

Clean the cutter after use.

Caution: Wear gloves to protect hands from metal splinters. Do not use an air gun; blasting with air can cause metal filings and/or dust to get into the eyes and respiratory system.

1. Disconnect unit.
2. Wipe or brush away all dirt and metal filings. Pay particular attention to the lower half of the piston, where dirt is more easily accumulated.

Oil-level check

As the cutters are hydraulically operated, the oil level must be checked at frequent intervals, preferably every day. Failure to maintain the oil at the proper level results in a drop in pressure and loss of cutting power.

Caution: Hydraulic oil is highly flammable. Keep away from sparks or naked flame. Do not smoke.

Caution: Hydraulic oil may cause inflammation of the eyes and skin. If ingested, it will cause diarrhoea and vomiting.

In case of eye contact, rinse in clean water for at least 15 minutes and consult a physician. In case of skin contact, wash thoroughly with soap and water.

In case of ingestion, consult a physician immediately. Do not deliberately induce vomiting.

1. Oil should be warm but not hot. Warm up unit if cold.
2. Adjust stopper and make three or four cuts, noting exactly at what point the rebar is actually breaking.
3. Pinch a short piece of rebar, stopping just before it breaks off. Unplug from power source.
4. With partially severed rebar in place, turn unit over so that oil-plug is uppermost. (If unit is hot, allow to cool down.)
5. Remove oil-plug and seal-washer (packing)

Caution: Never remove oil-plug when unit is hot or oil will spurt out.

1. Check that oil is level with bottom of plug hole. (i.e. That pump is full to the brim). If oil level is too low, top up with 20-weight hydraulic oil with anti-foam and anti-abrasion properties. (ISO viscosity grade VG46. E.g. Shell oil Tellus 46, Mobil oil DTE-25 or Esso Uni Power SQ46.)
2. After topping up, extract air from the system. Gently tilt the cutter lengthwise and return it to a level position. Top up again and tilt in the opposite direction. Repeat this process until all air has been extracted.

Caution: The cutter cannot function properly if the oil contains air bubbles.

1. Replace the seal washer (packing) and plug. Connect the cutter to power and completely sever the rebar.

Oil change

1. The hydraulic oil should be changed at least once a year, or sooner if it appears dirty.
2. Unplug the unit from the power source. Remove the oil plug and packing. Turn over and drain oil into a suitable receptacle. When oil ceases to drain, tilt the unit to the rear so that oil trapped in the piston housing can run out. When the housing is empty, tilt the unit in the opposite direction to empty the residue from the pump case.
3. With the drain hole uppermost, slowly fill the unit with fresh oil. Replace and lightly tighten the plug. Connect the unit to the power source and advance the piston three times. Unplug the unit and remove the oil plug. Top up the oil level and replace the plug.
4. Finally, follow the procedure for oil level check.

Note: Dispose of hydraulic oil in accordance with local regulations. Do not pour it into the sea, river, lake, or drains.

Bolt tightness

Once a week or after every 500 cuts, check the tightness of all bolts, especially those securing the housing to the cylinder. Loose bolts will result in a loss of power.

Carbon brushes

Inspect the two carbon brushes at least once every two months (normal brush life is 200 hours).

Care: Worn brushes will result in power loss, cause the motor to run and irreparably damage the armature's commutator.

1. Disconnect unit. 2. Unscrew both brush caps and pull out carbon brushes. 3. Replace brushes if less than 6 cm in length.
