2. Insert the battery cartage into charger until stops adjust-
ing to the guide of charger. Terminal cover of charger
can be opened with inserting and closed with pulling
out the battery cartridge.
3. When the battery cartridge is inserted, the red charging
light will light up and charging will begin with a preset
brief melody sound coming out for assurance as to which
sound will come out to notify the completion of charging.
4. With finish of charge, the charging light will charge from
red one to green one and the melody sound or buzzer
sound (a long deep) comes out to notify completion of
charge.
5. If you leave the battery cartridge in the charger after the
charging cycle is complete, the charger will switch into
its “trickle charge (maintenance charge)” mode which
will last approximately 24 hours.
6. Charging time varies by temperature (10°C (50°F) -
40°C (104°F)) that battery cartridge is charged at and
conditions of the battery cartridge, such as a battery car-
tridge which is new or has not been used for a long pe-
riod of time.
7. After charging, remove the battery cartridge from the
charger and unplug the charger from the power source.
•The battery charger is for charging OGURA-battery cartridge. Never use it for other purposes or for other
manufacturer’s batteries.
•If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a location
exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while.
Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger.
•If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the

last preset brief melody sound of completed charging.
2. Removing and re-inserting it within five seconds after
this action makes the melody sound change/
3. Every time removing and re-inserting it within another
five seconds after this, the melody sound changes in
order.
4. When the desired melody sound comes out, leave the
battery cartridge being inserted and the charge will be-
gin. When a "short deep" mode is selected, no completed
charging signals come out. (Silent mode)
5. With finish of charge, the green light remains lit with
the red light going out and the melody sound preset at
the insertion of battery cartridge or buzzer sound (a long
deep) comes out to notify completion of charge. (In se-
lected silent mode, no sounds come out.)
6. Preset melody sound remains stored even when the
charger is unplugged.
Changing melody of completed charging
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will
switch into its “trickle charge (maintenance charge)” mode and keep the battery cartridge fresh and fully charged.

ADDING OIL
This cordless rebar cutter is electro-hydraulic. When shipped from the factory, it was filled with oil. Do not
attempt to add oil as long as the tool performs well. Over a period of time the oil level will gradually go down.
Eventually this will cause a noticeable dropping off in performance. When this happens add oil as follows.
1. Place some rebar between the blades and pull the Trigger Switch.
2. Release the Trigger Switch just before the cut is completed to stop the tool.
3. Remove the Battery from the tool, so that the Blades cannot be moved accidentally.
4. Remove the Bolt (SB10✕15) which caps the oil filler hole. Add the oil, being careful not to allow any oil to
spill into the motor.
5. Replace the Bolt (SB10✕15) and tighten securely.
6. Reinsert the Battery into the tool and complete the cutting operation.
7. Repeat the above procedure several times until the oil level remains correct.
Only pure hydraulic oil as recommended by Ogura & Company Ltd., should be used in this tool.
Recommended oils include the Ogura supplied hydraulic oil, Super Hyrando #46 (Nippon Oil
Corporation); Shell Tellus Plus #46 (U.S. Shell); or equivalent spec anti-wear hydraulic oil, ISO
Viscosity Grade 46. Do not use other oils as these may cause damage to the seals and other internal
machine parts.
CAUTION

15
NOTE: The internal components of the pump and piston area have very close tolerances and are
sensitive to damage from dust, dirt, contamination of the hydraulic fluid or improper handling. The
disassembly of the pump housing requires special tools and training, and should only be attempted by
qualified repair personnel that have been properly trained and have the right tools. The improper
servicing of electrical components can lead to conditions that could cause serious injury. The pump,
piston components and all electrical parts should be serviced only by authorized repair shop, dealer or
