MAINTENANCE ON
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. Re-
place 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 blocks.
CAUTION: A loose or cracked
block may result in injury to op-
erator.
CLEANING
Clean your tool every day, preferably im
mediately after use.
CAUTION: Wear gloves to protect
hands from metal splinters.
Do not use an air gun: blasting with air
can cause metal filings and/or dust to get
into eyes and respiratory system.
Disconnect the unit. 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.
NEVER USE YOUR CUTTER
TO CUT REBAR IN
WET CONCRETE.
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 high-
ly 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
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
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 re-
bar 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,
oil-plug should be straight up. (If unit is
hot, allow cooling 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 if 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 68, Mobil oil
DTE-25 or Esso Uni power SQ46).
7. After topping off, extract air from sys-
tem. Gently tilt cutter lengthwise and re-
turn it to a level position. Top off again
and tilt in the opposite direction. Repeat
this process until all air has been extract-
ed.
CARE: Cutter cannot function
properly if oil contains air bub-
bles.
8. Replace seal washer (packing) and oil
plug. Connect cutter to power source and
completely sever rebar.
OIL-CHANGE
e hydraulic oil should be changed
at least once a year, sooner if it appears
dirty.
NOTE: Hydraulic oil should be
warm before draining
1. Unplug unit from power source. Re-
move oil-plug and packing. Turn cutter
over and drain oil into a suitable recepta-
cle. 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 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 bolts securing the housing to the
cylinder. Loose bolts will result in a loss
of power. Make sure that the bolts hold-
ing both cutter blocks are also tight
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.
1. Disconnect unit.
2. Unscrew both brush caps and pull out
carbon brushes.
3. Replace brushes if less than 6mm
or1/4” in length.
