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.
Hydraulic Oil Level Check
As the cutters are hydraulically operated, the hydraulic oil level must be checked at frequent
intervals, preferably every results in a drop in pressure and loss of cutting power.
CAUTION:
Hydraulic oil is highly flammable. Keep away from sparks and open flames. 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 unit if cold.
2.
Adjust stopper and
make three or four cuts, but not all the way through the rebar.
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 facing up. (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.
7. After topping off, extract air from system by gently tilting cutter lengthwise and return it to a level
position.
Top off again and tilt in the opposite direction. Repeat this process until all air has been extracted.
Cutter cannot function properly if oil contains air bubbles.
8. Replace seal washer (packing) and plug. Connect cutter power source and completely sever
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 off oil level and replace plug.
3. Finally, follow procedure for oil level check (Steps 2–8).
Note
: Dispose of used hydraulic oil in accordance with local regulations. Do not pour onto the
ground or into sewer drains, rivers or lakes.
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.
