SAFETY INSTRUCTIONS

Usage

Use NRB-22 NRB-25 RB-16 RN-22 NRB-32 rebar bender on concrete re-inforcing 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 using bender.

Provide safety barriers

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

Guard Against electric shock

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

Unplug tool

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

Beware of environment

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

Do not use cutter in a possibly lighted and clear of obstructions. Op 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 jewellery. Restrain long. The use of a safety-helmet and rubber soled boots is recommended safety gloves are worn, be especially careful that gloves does not get caught in moving parts.

Keep visitors aways

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

Maintain cutter with care

Inspect cutter before each application. Faulty or loose cutter blocks cc result in personal injury . Keep handle dry, clean and free from oil a grease. Keep housing and piston free of dirt and iron filings. Check screws or bolts are loose or missing. Following instruction for maintenance . Inspect switch, cord,plug and any extension cable at re intervals.

Store carefully

When not in use, store bender and accessories in a dry place where can't 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 power supply may result in electric shock operator.

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

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

Cable length	110/115V	230V
	Cable size (AWG)	Nomibal diameter
Up to 10m (33 ft)	16	1.0mm^2
Up to 15m (50 ft)	14	1.25mm^2
Up to 30m (100 ft)	10	1.5mm^2

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

Warm-up

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

Stopper adjustment

The adjustable stopper function to maintain the rebar in tln cold weat warm up unit for 30-60 seconds so that the hydraulic oil reaches the viscosity. Pull trigger -switch to extend piston and release 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 air vents.

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

1. If hydraulic oil exceeds 70. (158.F) in temperature, power will drop. Allow 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 motor is unusually hot, check carbon-Brushes.

3. Pull the #14 part valve to make the bending piston return back total after each bending.

MAINTENANCE

CLEANIN

Cleaning 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 eyes and respiratory system.

1. Disconnect unit.

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

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 ar naked flame. Do not smoke.

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

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

In case of ingestion, consult a physician immediately. Do not deliberate 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. Unp from power source.

4. With partially severed rebar in place, turn unit over so that oil-plug 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 to the brim). If oil level is too low, top up with 20-weight hydraulic 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 system. Gently tilt cutter lengthwise Return it to a level position. Top up again and tilt in the opposite dir Repeat this process until all air has been extracted.

CARE: Bender cannot function properly if oil contains air bubbles.

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

Oil change

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

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

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

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

Note: Dispose of hydraulic oil in accordance with local regulations. Do 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 in a loss of power.

Carbon brushes

Inspect the two carbon brushes at least once every two months. (nor 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.
