General Safety Precautions

• Usage
  Use rebar cutters on concrete re-forcing bars only.

• Restrict use to designated materials
  There is always a chance that the cut end may shoot out, especially if less than 30cm in length. Exceeding designated material specifications greatly increases this risk and will also damage the tool. Do not attempt to cut 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 cutter. Provide safety barriers
  Erect safety screens to protect co-workers from possible flying ends. Place safety screen under the rebar when working in high places.

• Exercise proper control
  Hold cutter firmly and maintain proper footing and balance. Do not over-reach when working in a high place, secure the cutter to scaffolding with a safety rope. Check that the power cord is not fouled and keep the cord away from sharp edges and heat. Check that all adjusting wrenches have been removed before using the cutter.

• Guard Against electric shock
  To avoid possible electric shock, do not handle the cutter with wet hands or use the cutter in the rain or damp places. Be aware of all power lines, electric circuits and other hazards that may be contacted, especially those that are 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 the plug from the outlet by pulling the cord. Always check that the switch lock if OFF before plugging in.

• Beware of environment
  Do not use t h e cutter in the presence of flammable materials (e.g. Paint, thinner,petroleum products, adhesives).
  Do not use the cutter in a possibly lighted and clear of obstructions. 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 safety-helmet and rubber soled boots is recommended . If safety gloves are worn, be especially careful that gloves do 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 the distraction of the operator.

• Maintain cutter with care
  Inspect cutter before each application. Faulty or loose cutter blocks could result in personal injury. Keep handle dry, clean and free from oil and/or grease. Keep housing and piston free of dirt and iron filings. Check that no screws or bolts are loose or missing. Following instructions for maintenance. Inspect the switch, cord, plug and any extension cable at regular intervals. Store carefully

• When not in use, store t h e cutter and accessories in a dry place where they can’t be accessed by an unauthorized person.

Operating Instructions

• Caution: Indicates hazards that could result in minor personal injury and/or product damage.
• Care: Indicates hazards that will result in product damage.

Pre-use checks

1. Check oil level.

2. Check the condition of cutter blocks and the tightness of cutter block bolts.
   Caution: Using loose or cracked cutter blocks may result in injury to operators as well as damage to the unit.

3. Check that the power source is appropriate for the cutter.
   Care: If t h e voltage is too high, the motor will burn out. If the voltage is too low, insufficient power will be generated. Never use DC current.

4. Check that the power supply is properly earthed.
   Caution: Failure of the earth’s power supply may result in an electric shock to the operator.

5. Check that cord is undamaged and that plug is not loose.
   Caution : Cut or abraded covering could result in a short and electric shock to the operator.

Warm-up
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 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 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 on 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 stooper needs no further adjustment while cutting rebar of the same diameter, but must be re-set for different size rebar.
• Caution: Failure to correctly set the stopper will result in excessive wear of the cutter block and may cause a cut end to fly out.

Cutting

1. Insert rebar between the stopper and front cutter block, making sure that it is properly seated in U-shaped support.
2. Pull the trigger -switch and keep depressed while the piston advances and the rebar is cut. ( 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) as the cut end tends to fly out.
   Caution : Flying ends are a hazard to all personnel in the vicinity. Erect safety screens.

2. Do not cover air vents.
   Care : If events are covered , motor will overheat and may burn out.

3. If hydraulic oil exceeds 70 ° (158 F) in temperature, power will drop.
   Allow until to cool before resuming operation. (Be particularly careful in summer, when the aluminum pump case heats up quicker.) even if gloved.
   Once piston has been retracted , pull trigger-switch long enough to partially advance piston. Unplug unit. And check piston and housing for accumulated dust iron filings that may be jamming the piston. After cleaning, 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 block and housing. Also, check condition of cutter blocks. If either cutting edge is dull or chipped, remove retaining bolts and rotate both blocks so that two new edges come into use. Replace and tighten 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

Cleaning cutter after use.

• Caution: Wear gloves to protect hands from metal splinters. Do not use an air-gun, blasting with air can cause metal filing 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 and naked flame. Do not smoke.

Caution: Hydraulic oil may cause inflammation of the eyes and skin. If ingested, it will cause diarrhea 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 the unit if cold.

2. Adjust the stopper and make three or four cuts, noting exactly at what point the rebar is actually breaking.

3. If hydraulic oil exceeds 70 ° (158 F) in temperature, power will drop.

4. Allow until to cool before resuming operation. (Be particularly careful in summer, when the aluminum pump case heats up quicker.)

5. If a drop in power is observed and motor is unusually hot, check carbon brush .

6. If the piston should ever fail to retract completely, push rear cutter block backward to manually retract the piston.
   Caution: Use rebar or flat metal bar for this purpose. Never push cutter block with any part of the hand, even if gloved.

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