SAFETY INSTRUCTIONS

Usage

Use NRB-22, NRB-25, RB-16, RN-22, NRB-32 rebar bender on concrete reinforcing bars only.

Restrict use to designated materials

Don't use the machine to bend very hard rebar. The hard rebar may and will also damage the tool. Do not attempt to bend rebars.

Harder, thicker, or thinner than those specified

Use eye protection

Wear safety goggles, safety glasses with side shields, or a face shield when using the bender.

Provide safety barriers.

Erect safety screens to protect co-workers from possible flying ends. If working in high places, place a safety screen under the rebar.

Guard against electric shock.

To avoid possible electric shock, do not handle the cutter with wet hands, and do not use the cutter in rain or damp places. Be aware of all power lines, circuits, and other hazards that may be contacted, especially those that are below the surface or otherwise hidden from view.

Unplug the tool.

Disconnect the cutter from the outlet when not in use and before cleaning, adjusting, or servicing. Do not disconnect the plug from the outlet by pulling the cord. Always check that the switch lock is OFF before plugging in.

Beware of the environment.

Do not use the cutter in the presence of flammable materials (e.g., paint, thinner, petroleum products, adhesives).

Do not use the cutter in a possibly lighted area and keep it clear of obstructions. The operator should at all times have an unobstructed view of the cutter, rebar, and surrounding area.

Wear proper apparel.

Do not wear loose clothes, dangling objects, or jewelry. Restrain long hair. The use of a safety helmet and rubber-soled boots is recommended. If safety gloves are worn, be especially careful that the gloves do not get caught in moving parts.

Keep visitors away.

Keep all visitors at a safe distance from the work area for their own protection and to prevent distraction of the operator.

Maintain the cutter with care.

Inspect cutter before each application. Faulty or loose cutter blocks can result in personal injury. Keep handle dry, clean and free from oil and grease. Keep housing and piston free of dirt and iron filings. Check screws or bolts are not loose or missing. Follow instructions for maintenance. Inspect switch, cord, plug and any extension cable at regular intervals.

Store carefully

When not in use, store bender and accessories in a dry place where they cannot be accessed by unauthorized persons.

INSTRUCTIONS

Caution: Indicates hazard that could result in minor personal injury or product damage.

Care: Indicates hazard that will result in product damage.

Pre-use checks

1. Check oil level.
2. Check condition of bender blocks and tightness of bender block bolt.
3. Check that the power source is appropriate to the bender.

CARE: if voltage is too high, the motor will burn out. If the voltage is low, insufficient power will be generated. Never use DC power.

1. Check that power supply is properly earthed.

CAUTION: Failure to earth the power supply may result in electric shock to the operator.

1. Check that the cord is undamaged and that the plug is not loose.

If an extension cable is to be used, make sure that it is undamaged and that it is the proper thickness for the length. See the table below.

Cable length	110/115V	230V
	Cable size (AWG)	Nomibal diameter
Up to 10m (33 ft)	16	1.0mm2
Up to 15m (50 ft)	14	1.25mm2
Up to 30m (100 ft)	10	1.5mm2

1. Before plugging in, make sure that the switch lock is OFF.

Warm-up

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

Stopper adjustment

The adjustable stopper function is used to maintain the rebar in position. In cold weather, warm up the unit for 30-60 seconds so that the hydraulic oil 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.

When bending for the first time, you can make a mark at the position screw according to the bending angle, so that you can bend the same angle next time.

POINTS OF ATTENTION

1. Do not cover the air vents.

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

1. If the hydraulic oil exceeds 70°C (158°F) in temperature, power will drop. Allow the unit to cool before resuming operation. (Be particularly careful in summer, when the aluminium pump case heats up quicker.)
2. If a drop in power is observed and the motor is unusually hot, check the carbon brushes.
3. Pull the #14 part valve to make the bending piston return fully after each bending.

MAINTENANCE

CLEANING

Clean the bender every day, preferably immediately 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 eyes and the respiratory system.

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

Oil level check

As the bender is 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 bending power.

Caution: Hydraulic oil is highly flammable. Keep away from sparks or naked flames. 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 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 can be filled 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 Tellus 46, Mobil DTE-25, or Esso Uni Power SQ46).
2. After topping up, extract air from the system. Gently tilt the cutter lengthwise. Return it to a level position. Top up again and tilt in the opposite direction. Repeat this process until all air has been extracted.

CARE: The bender cannot function properly if the oil contains air bubbles.

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

Oil change

The hydraulic oil should be changed at least once a year, sooner if it appears dirty.

1. Unplug the unit from the power source. Remove the oil plug and packing. Turn

the bender over and drain the oil into a suitable receptacle. When the oil ceases to drain out, tilt the unit to the rear so that oil trapped in the piston housing can come out. When the housing is empty, tilt the unit in the opposite direction to empty residue in the pump case.

1. With the drain hole uppermost, slowly fill the unit with fresh oil. Replace and lightly tighten. Connect the unit to the power source and advance the piston two or three times. Unplug the unit and remove the oil plug. Top up the oil level and re-plug.
2. Finally, follow the procedure for the oil-level check. (Steps 2~8.)

Note: Dispose of hydraulic oil in accordance with local regulations. Do not pour 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.
