Operating Instructions

 

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

Care :Indicates hazard that will result in product damage.

Pre-use checks

 

1. Check oil level.

2. Check condition of cutter blocks and tightness of cutter block bolts.

! Caution : Using loose or cracked cutter blocks may result in injury to operators as well as     damage to unit.

3. Check that the power source is appropriate for the cutter.

   Care : If 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 power supply is properly earthed.

! Caution : Failure to earth power supply may result in electric shock to 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 operator.

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

Warm-up

In cold weather , warm up unit for 30-60 seconds so that the hydraulic oil 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 the correct position during cutting and must be properly set for each size of rebar before making a cut.

1. Screw in stopper to provide sufficient clearance for rebar.

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

3. Keeping rebar at right angels (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 a different size rebar.

! Caution: Failure to correctly set the stopper will result in excessive wear of 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 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.)

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

5. If piston should ever fail to retract completely, push rear cutter block backwards to manually retract piton.

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

! Caution : A loose or cracked block may result in injury to 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 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 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 unit 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.

6. check that oil is level with bottom of plug hole. (i.e. That pump case 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.)

7. After topping up, extract air from system. Gently tilt 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.

Care: Cutter can't function properly if oil contains air bubbles.

8. Replace seal washer (packing) and plug. Connect cutter to power source 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 cutter over and drain oil into a suitable receptacle. When oil ceases to drain out, tilt unit to rear so that oil trapped in the piston housing can run out. When housing is empty, tilt unit in the opposite direction to empty the residue in the pump case.

2. With drain-hole uppermost, slowly fill the unit with fresh oil. Replace plug and lightly tighten. Connect unit to power source and advance piston two or three times. Unplug unit and remove oil-plug . Top up oil level and replace plug.

3. Finally follow procedure for oil level check.

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 hot 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 lengh.
