Maintenance
Always ensure power is disconnected before performing maintenance.
Cleaning
- Always wear gloves to protect your hands from metal splinters when cleaning.
- Wipe or brush away all dust and metal filings from the Band Table after use to prevent debris entering the machine (can use compressed air).
Bend Table Bolts
- Ensure Bend Table Bolts are tightened before use.
Carbon Brushes
Inspect carbon brushes monthly. Worn brushes will result in power loss and
cause irreparable damage to the armature’s commutator. Check brushes
immediately if a loss of power or electrical fault is experienced.
Replacing Carbon Brushes
- Open the access side panel and locate the motor housing(s) with black lid.
- Locate the brush caps on both sides near the top of the motor housing(s).
- Open the brush caps with a screwdriver and remove carbon brushes from the machine.
- Inspect the carbon brushes and replace where worn or damaged.
- Reinstall new carbon brushes and brush caps securely.
- Replace access side panel.
Lubrication
-
Lubricant shall be checked every 2 months for heavy usage or when loss of power is experienced.
-
Always use approved lubricant with high corrosion and friction resistance properties.
-
Apply lubricant via grease gun to lubricant hole to ensure lubricant chamber remains full.

Additional Instructions for Rebar Cutter (Rebar Bender/Cutter Model)
-
Do not operate bender and cutter at the same time.
Safety
- Keep body parts well clear of cutting blocks when the machine is switched on.
- Never attempt to cut rebar outside of the model’s prescribed diameter range (refer to table in Specifications & Parts section).
- Do not cut short lengths.
- Inspect cutter before each use (refer to the Maintenance section). Do not use it when quality has been compromised.
- Beware of ejected objects during the cutting process. Always wear approved safety glasses.
- Use protective gloves when cleaning machine or handling cutter blocks as edges are very sharp.
- Do not touch pump housing after use as it will be hot. Wait for machine to cool.
- Where available, safety guard should be installed.
- Use Allen Key to loosed and activate Release Valve function when required.
Cutter Parts
Note: Cutter body varies with different models – use as a general guide.
Operating Machine
Pre-use Checks
Check condition of cutter blocks and tightness of cutter block bolts (refer to
Maintenance section).
Warm Up
In cold weather, warm up cutter by repeating cut cycle for 60 seconds to
ensure hydraulic oil reaches proper viscosity.
Stopper Adjustment
Adjustable stopper must be set in correct position dependent on size of rebar.
- Insert rebar into U-shaped support.
- Keeping rebar at 90˚ to machine, screw in stopper until it is just touching the rebar.
Cutting Procedure
- Securely fasten the pedal switch chord to the pedal switch point 3 input.
- Connect to a power source and observe the power indicator light on machine’s face indicating the machine is ready for use.
- Insert rebar between the stopper and front cutter block, making sure it is horizontally seated in U-shaped support.
- Press the pedal switch connected to pedal switch point 3 input while cutter rod advances and fully cuts the rebar.
- Release the pedal switch only once the rebar has been fully cut to allow the cutter rod to retract.
Note: Power will be compromised if hydraulic oil exceeds 70˚C. Allow the
machine to cool before resuming operation.
Note: Do not cut rebar on an angle. Incorrect placement of rebar may
cause damage to cutter blocks and/or cutter rod, voiding the warranty.
Maintenance
Always ensure power is disconnected before performing maintenance.
To access Rebar Cutter
- Open the access side panel and locate the rebar cutter with a black cover.
- Remove the screws to lift the cover and access the rebar cutter.
Cutter Blocks
Check cutter blocks for damage before each use. If cutter block is damaged,
replace block before the next use as per the following diagram:
- Check cutter block bolts for tightness before each use. Use protective gloves when handling cutter blocks as edges are very sharp.
Cleaning
Clean machine after each use.
Use protective gloves when cleaning to protect hands from metal splinters.
Do not use air gun as this may cause dust and metal filings to enter vents.
- Extend cutter rod and disconnect from power source.
- Wipe or brush away all dust and metal filings. Pay particular attention to lower half of cutter rod.
- Connect to power source and press pedal switch to complete cut cycle.
Oil Level Check
Check oil every 2 months or if loss of power is apparent in the rebar cutter.
Hydraulic oil is highly flammable; keep away from sparks and naked flame.
In case of ingestion or eye contact, consult a physician immediately.
- Adjust the stopper and make 3-4 cuts, noting exactly the point at which the rebar is breaking.
- Pinch the next bit of rebar, stopping just before it breaks. Unplug the machine from the power source.
- Turn the unit over so the oil plug is uppermost (if the machine is hot allow it to cool down first).
- Remove the oil plug and seal the washer (never remove when the machine is hot).
- Check oil is level with the bottom of the plug hole. If the oil is too low, top up with approved ISO VG46 oil.
- Remove air bubbles – gently tilt cutter lengthways and return to level position. Top up and tilt the cutter in the opposite direction. Repeat this process until all air has been extracted.
- Replace the seal washer and oil plug.
- Connect to power source and completely sever rebar.
Oil Change
Change oil at least once a year or sooner if it appears dirty.
- Unplug the machine from the power source.
- Turn the unit over so the oil plug is uppermost (if the machine is hot allow it to cool down first).
- Remove the oil plug and seal the washer (never remove when the machine is hot).
- Turn the cutter over and drain oil into a suitable receptacle. When oil ceases to drain, tilt the machine to the rear to allow oil trapped in the piston housing to drain out. When the housing is empty, tilt the unit in the opposite direction to empty the residue in the pump case.
- Once all oil has been drained from the machine, turn the unit over so the oil plug is uppermost.
- Slowly fill the machine with fresh oil and replace the seal washer and oil plug.
- Connect the machine to the power source and follow the procedure for the Oil Level Check.
Note: Dispose of hydraulic oil under local regulations.
Bolt Tightness
All bolts should be checked for tightness weekly or after every 500 cuts
(whichever comes first).
Carbon Brushes
Inspect carbon brushes monthly. Worn brushes will result in power loss and
cause irreparable damage to the armature’s commutator. Check brushes
immediately if a loss of power or electrical fault is experienced.
Replacing Carbon Brushes
- Unplug the machine from the power source.
- Locate the brush caps on both sides near the back of the motor housing.
- Open the brush caps with a screwdriver and remove carbon brushes from the machine.
- Inspect the carbon brushes and replace where worn or damaged.
- Reinstall new carbon brushes and brush caps securely.
