involved you must not use the machine Please
contact your dealer for more information.
• Check that all couplings, connections and hydraulic
hoses are in full working order.
•All operators shall be trained in the use of the machine.
The owner is responsible for ensuring that the
operators receive training.
•Make sure that all hoses and electrical cables are
connected to the machine correctly before you start the
machine.
• People and animals can distract you, causing you to
lose control of the machines. For this reason, you
should concentrate and focus on the task at hand.
• Never leave the machine unsupervised with the motor
running.
•Make sure no clothing, hair or jewellery can fasten in
moving machine parts.
• Onlookers can be injured.You should never, therefore,
start the machine without being certain that no people
or animals are within the work area. Secure the work
are by cordoning off if necessary.
• Never disconnect any of the hydraulic hoses without
first shutting off the unit and ensuring the motors have
stopped completely.

should arise, press the red emergency stop button on
the side of the remote control or press the green start/
stop button on the remote control.
• Wear suitable personal protective equipment, such as
a helmet, protective shoes, eye and hearing protection.
Hearing protection must always be worn as sound
levels exceed 85 dB(A).
• Working close to power lines:
When using hydraulic tools close to power lines, the
hydraulic hoses must be marked and approved as “non-
conducting dielectric”. The use of any other type of
hoses can result in serious physical injury or even death.
When replacing hoses, hoses marked “non-conducting
dielectric” must be used. The hoses must be regularly
checked for their electrical conductive insulation in
accordance with special instructions.
• Working close to gas conduits:
Always check and mark out where gas pipes are
routed. Working close to gas pipes always entails
danger. Make sure that sparks are not caused in view

serious personal injury or death.
• Mark out all hidden pipes such as water pipes and gas
pipes.
• Check that power cables and the Canbus cable are not
damaged or can be damaged while working.
• Check tools, hoses, and connections daily for leakage.
A crack or leak can cause “hydraulic fluid injection” in
the body or result in other serious personal injury.
• Do not exceed the rated working pressure for the
specific tool or hydraulic hose.Increased pressure can
cause leakage or bursting.
•Do not check for leakage with your hands, contact with
the leak can result in serious personal injury caused by
the high pressure in the hydraulic system.
• The tool must not be carried or lifted by the hoses.
• Do not misuse hoses.
• Do not use hoses that are twisted, worn, or damaged.
•Check that the hoses are connected correctly to the tool
and that the hydraulic couplings lock as intended before
pressurising the hydraulic system. The couplings are
locked by turning the outer sleeve on the female cou-
pling so that the slot moves away from the ball.

Introduction Operator's Manual RC 455
Introduction
Husqvarna RC 455 “Smartbox” is a small and compact
control unit developed for use as an link between the
hydraulic unit without control valves such as a diesel-
driven generating set and Husqvarna WS 355, WS 462,
WS 463 and CS 2512.
As RC 455 is equipped with a priority valve, the diesel-
driven generating set, which can supply a flow, can be
used to control machines that are driven by several
different flows, for example, to drive the blade and motion.
By connecting the above units to RC 455, they can be
controlled in the same way as if they were connected to a
PP 455 E hydraulic unit.
RC 455 is supplied with the following equipment:
1 x RC 455
1 x remote control
1 x hose assembly, 8 m
1 x Canbus cable, 8 m
1 x 12 V DC connection cable
.

What is whatOperator's Manual RC 455
What is what
1. Incoming hydraulic connections
The hoses from the hydraulic unit are connected to
these 3/4-inch couplings. This is the machine's input
flow. The flow in the hose connected to the female
coupling (1a.) drives the tool, while the flow through the
male coupling (1b) is the return flow to the hydraulic
unit.
2. Outgoing hydraulic connections
The supplied hydraulic hoses are connected to these.
These are then connected to suitable hydraulic tools.
The large couplings control the drive of the attached
tool while the smaller control the blade and trolley
motion. The flow in the hoses with female couplings
control the trolley motion while the male couplings
control the blade motion.
3. Canbus cable connection
The Canbus cable that sends the control signals
between RC 455 and the remote control is connected
here. The Can bus cable is equipped with a locking
mechanism so the cable is not loosened
unintentionally.
4. 12 volt DC connection
The power that drive RC 455 is connected here. The
power is appropriately taken from the hydraulic unit
used together with RC 455. The connection is
equipped with a locking mechanism so that the cable
is not loosened unintentionally.
The 12 volt cable is supplied from the factory with a
“Pig tail”. This is connected by the operator to the
available Hydraulic unit. See also under “Assembling/
Installing equipment”
5. Automatic fuse
Trips when the incoming 12 volt DC current is too high.
Press in to reset.
6. Feet
Protect the machine against vibrations and dirt.
7. Incoming water connector
8. Outgoing water connector
9. Remote control
The remote control is used to control RC 455. In order
for the remote control to work the hydraulic unit's
ignition must be switched on.

DC voltage. If the machine is connected to
a higher voltage, the equipment can be
damaged and the operator can be seriously
injured.
3. Connect the remote control using the supplied Canbus
cable. Tighten the cable connector by hand.
When the machine is equipped with a radio, a radio
antenna can be connected instead of a Canbus cable.
This is screwed into the same socket as where the
Canbus cable should have been fitted.
4. Check that the emergency stop on the remote control
is not activated. The display on the remote control now
shows “SMARTBOX CONNECT HOSE ASSEMBLY”
5. Connect the incoming hydraulic hoses from the diesel-
driven generating set to RC 455.
6. If CS2512 is to be used, connect the pressure
reduction block's female couplings to the male
couplings on RC 455.
7. Connect the hydraulic hoses from RC 455. There are
two types of hydraulic hoses between RC 455 and the
selected tool (WS 462, 463 or CS 2512):
On a wall saw in the WS 400 series, the four thin hoses
control the saw's motion motors, i.e. the saw's blade
motion and trolley motion. The two thick hoses drive
the blade.
When a wire saw CS 2512 is connected to the unit, the
two thin hoses control the tension on the magazine
arm while the two thick hoses drive the wire.
The hoses in the hose assembly marked with red discs
by the coupling are to be connected to the couplings
marked with similar discs.
8. When all hydraulic hoses are connected, confirm on
the remote control with “OK”

Work process for wall sawing Operator's Manual RC 455
Work procedure for wire cutting
When all the equipment has been assembled cutting can
start. In order for the saw to cut as efficiently as possible it
should be started as follows:
1. Assemble the pressure reduction block supplied with
the wire saw on the hydraulic unit according to the
instructions on the block.
2. Connect the two smaller hydraulic hoses to the
pressure reduction block. The hoses in the hose
assembly marked with a red disc by the coupling shall
be connected to the hose on the pressure reduction
block that is also fitted with a disc.
3. Close the valve on the pressure reduction block by
turning the knob anti-clockwise until it stops and then
two turns back.
4. Start the engine's working speed by pressing the green
button on the remote control once.
The engine on the diesel-driven generating set
changes from idling to working speed and starts to
produce a flow.
To stop the flow and to get the hydraulic unit's motor to
idle, press the green button on the remote control once
again.
5. Set the feeding flow on the unit to max by turning the
control on the remote control clockwise.
6. Tension the wire by carefully turning the knob on the
pressure reduction block clockwise until the wire is
tensioned sufficiently. Make sure to always check that
the wire is seated correctly in all the wheels on the
saw.
7. Start the motor's rotation by turning the control for
motor rotation on the remote control clockwise.
8. Carefully increase the motor speed by turning the
control for motor rotation. A suitable working pressure
when cutting usually lies between 100 and 130 bar, but
varies depending on how many wheel sets are used in
the magazine, how much wire is in use and the
hardness of the material to be cut.
9. When material is cut away the working pressure can
drop, which is shown on the display, and the magazine
must be tensioned. Do this by turning the knob on the
pressure reduction block clockwise.

3.3 Change the start point for blade motion
The start point value should be adjusted so that the
blade motion is as low as possible when the blade
motion knob is in the zero position, i.e.in the middle of
the left and right end positions.
A too low value results in the need to turn the knob
further from the zero position before the blade motion
starts.
A too high value results in the blade motion being too
high when the knob is turned from the zero position.
State the start point value:
• Press OK when the part menu is shown.
• Press OK.
The display shows: CHANGE START POINT and a
percentage value.
• Scroll using the arrow keys to state the required start
point. Hold the arrow key held down to increase the
scrolling speed. The scale is graduated from 1-100 %.
• Press OK.
• Press the down arrow to continue to the next part
menu.
3.4 Change the end point for blade motion
The end point value should be adjusted so that the blade
motion speed is as high as possible when the blade
motion knob is turned to the right.
A too low value results in the full blade motion speed
never being reached.
State the end point value:
• Press OK when the part menu is shown.
The display shows: CHANGE END POINT and a
percentage value.
• Scroll using the arrow keys to state the required end
point. Hold the arrow key held down to increase the
scrolling speed. The scale is graduated from 1-100 %.
• Press OK.
• Press the down arrow to continue to the next part
menu.
3.5 Change the ramp time for the feed
The ramp time value states how quickly the feeding speed
shall change when the blade motion knob or the trolley
motion knob is turned.
The defined ramp time value for feeding applies to both for
the blade motion and the trolley motion speeds.

4 Sensor on/off calibrate
This sub-menu contains the setting options for the
hydraulic unit's different pressure sensors.
The sub-menu consists of seven part menus:
4.1 Temperature sensor for hydraulic oil
4.2 Pressure sensor for the filter
4.3 Voltage sensor
4.4 Pressure sensor for hydraulic pressure
4.5 Calibrate pressure sensor for hydraulics
4.6 Calibrate voltage sensor
4.7 Calibrate potentiometer
4.1 Temperature sensor for hydraulic oil
A temperature sensor is fitted by the electronic card. The
sensor ensures that the electronics do not overheat.
When the temperature sensor is on, the control system
continuously reads the temperature.
NOTE!
The hydraulic unit can be damaged, if the
temperature sensor is switched off.
Turn on/ turn off the temperature sensor:
• Press OK when the part menu is shown.
The display shows: TEMP. SENSOR FOR HYDR. OIL
and ON or OFF.
• Press OK to switch between ON and OFF.
• Press the down arrow to continue to the next part
menu.
4.4 Pressure sensor for the hydraulic pressure
The pressure sensor measures the hydraulic pressure to
the blade
NOTE!
The hydraulic unit's control system switches
off, if the pressure sensor is switched off. The
hydraulic system may then be difficult to
control with a high load.
Turn on/ turn off the pressure sensor:
• Press OK when the part menu is shown.
The display shows: PRESSURE SENSOR FOR
HYDRAULIC PRESSURE and ON or OFF.
• Press OK to switch between ON and OFF.
• Press the down arrow to continue to the next part
menu.
4.5 Calibrate pressure sensor for hydraulics
The pressure sensor that measures the oil pressure for
blade rotation is possible to calibrate.
The pressure sensor must be calibrated according to the
order zero point and maximum point.
To calibrate the zero point:
1. Connect the incoming power cable to 63 A.
2. Connect an oil pressure reducing valve with a pressure
gauge to the blade rotation's hydraulic couplings.
3. Select the sub-menu “Sensor on/off calibrate” from the
“Settings” menu.
4. Scroll using the arrow keys and press OK when
“Calibrate pressure sensor for hydraulics” is shown.
5. Press OK again when the display shows CALIBRATE
ZERO POINT.
6. Start the hydraulic unit.
7. Adjust the oil pressure reduction valve to 0 bar.
8. Press arrow up/down until the value for the oil pressure
is shown as 0 bar, i.e. the same value as on the
pressure gauge on the oil pressure reduction valve.
