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 pres-
sure 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 inflam-
mation of the eyes and skin. If ingested, ti 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, 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 actu-
ally breaking.
3. Pinch a short piece of rebar, stopping just
before it breaks off. Unplug unit from power
souce.
4. With partially severed rebar in place, turn
unit over so that oil-plug is uppermost. (If unit
is hot, allow to cool down) and advance piston
two or three times. Unplug unit and remove
oil-plug, Top up oil-level and replace plug.
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).
7. After topping up, extract air from system.
Gently tilt cutter leengthwise 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 cannot function properly if oil
contains air bubbles.
8. Replace seal washer (packing) and plug.
Connect cutter to power source and complete-
ly 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 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 ad-
vance piston two or three times. Unplug unit
and remove oil-plug. Top up oil-level and re-
place plug.
3. Finally, follow procedure for oil-level check.
(Steps 2~8.)
NOTE: Dispose of hydraulic oil in accordance
with local regulations. Do not pour into the
sea, a river, a 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. (Nominal 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 commutador.
1. Disconnect unit.
2. Unscrew both brush caps and pull out car-
bon brushes.
3. Replace brushes if less than 6 cm in length.
