Additional instructions for rebar cutter
(Rebar cutter and bender Model )
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 glassed with side shields or a face shield when using 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 high place , secure cutter to scaffolding with a safety rope. Check that power cord is
not fouled and keep cord away from sharp edges and heat. Check that all adjusting wrenches
have been removed before using cutter.
Guard Against electric shock
To avoid possible electric shock, do not handle cutter with wet hands or use 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 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. 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 jewellery. Restrain long hair. The use of a
safety-helmet and rubber soled boots is recommended . If 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 could result in personal
injury . Keep handle dry, clean and free from oil and/or grease. Keep housing and piston free of
12
dirt and iron filings. Check that no screws or bolts are loose or missing. Following instruction
for maintenance . Inspect switch, cord,plug and any extension cable at regular intervals.
Store carefully
When not in use, store cutter and accessories in dry place where they can't be accessed by
unauthorized person.
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.
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.
· 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 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.)
13
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.
14
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.
2. 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.
3. 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.
4. 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.
