Install the po wer unit
Connecting the units
Connect the po wer tool to the designated power take-off,
note that there are two different power take-offs. The
upper power take-off is used for the PRIME™ family
products.The bottom power take-off is used for wall saws
(WS). For more information, see the ”Technical data”
section.
Connect the cooling water
• Connect the water hose to the incoming water
connector. Remember to use clean cooling water to
avoid dirt clogging up the water system.
The power pack is equipped with an electric water
valve, which is closed when the power pack is
activated. When the power pack is without electricity,
the valve is open to be able to drain water coolant if
there is a risk of freezing.
For more information, see the ”Technical data” section.
The other water connection should be connected to the
power tool, the power tool has various regulating taps for
regulating the flow of cooling water to the tool. See the
operator’s manual for the respective power tools.
!
W ARNING! Place the power unit on the
workplace, making sure that it is
standing on a stable surface and that it is
protected from water spray.
Connect the power unit to a grounded 3-
phase outlet.
Always connect the machine through an
ground fault circuit interrupter with
personal protection, i.e. an ground fault
circuit interrupter that trips at an ground
fault of 30 mA.
NO TICE! The cooling water will not turn off during a
power failure.

ASSEMBLING AND ADJUSTMENTS
8 – English
Connect a po wer source
•Connect the incoming power cable (380-400 V, 32 A
European connector). Power packs equipped with a
single phase socket (230 V) must also have a neutral
wire in order for the socket to work. The power pack
functions even if there is no neutral wire present.
To be able to use full power output, the power unit
must be connected to a 32 A fuse. With a 16 A or 25
A fuse the power output is lower so as not to overload
the fuse. This is selected in the menu under drive
selection.
At lower voltage there is a linear reduction in available
output down to 80%.
For more information, see the ”Technical data” section.
• During operation, fit together the covers for the cable
and the power unit to avoid dirt entering the covers
which could damage the connector.
A petrol or diesel driven generator can be used as a
power source if sufficiently powerful. See typical
generator operation cases in Technical Data. The
generator must be grounded to safeguard the function of
the power unit.
Battery
The remote control battery is a Li-ion type. Operating time
is about 8-10 hours per charge. Extreme cold impairs the
battery’s capacity and operating time. Operating time is
also affected by the extent to which the display has been
active.
Use only original batteries for this product. Contact your
dealer for more information.
An exhausted battery must not be disposed of as
household garbage! Leave it at your nearest service
agent or collection point.
Insert / remove battery
•Insert / remove the battery.
Charge the battery.
Before using the remote control for the first time the
battery has to be charged.
To charge with the battery charger
Charging time for a flat battery is approx. 2-3 hours. The
diode is orange when charging starts and becomes green
when the battery is fully charged.When the battery is fully
charged the charger supplies the battery with
maintenance current until the battery is removed from the
charger.
Keep the battery charger dry and protected against
temperature fluctuations.
To charge with the CAN cable
The charging efficiency with the CAN cable is less than
with the battery charger and it therefore takes a bit longer
to charge the battery.
If the battery is removed while the remote control is
connected to the CAN cable, the battery symbol in the
remote control will be stricken through to indicate that
there is not battery available.
NOTICE! A generator which on some occasion
generates an input voltage outside the voltage range
specified in the technical data can damage the power
unit.

General safety precautions
Work area safety
•Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
•Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
•Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
Electrical safety
•Power tool plugs must match the outlet. Never
modify the plug in any way. Unmodified plugs and
matching outlets will reduce the risk of electric shock.
•Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
•Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
•Do not misuse the cable. Do not use the cable to
carry or pull the power tool, or to disconnect the
power tool from the power take-off. Keep the cable
away from heat, oil, sharp edges and moving
parts. Damaged or tangled cables increase the risk of
electric shock and must therefore be replaced at a
service workshop.
•When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
Personal safety
•Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
•Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
•Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result
in personal injury.
•Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
•Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
•If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Power tool use and care
•Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
•Do not use the power tool if the designated on/off
function for each power tool does not turn it on
and off. Any power tool that cannot be controlled
correctly is dangerous and must be repaired.
•Disconnect the plug from the power source and/or
the battery pack from the power tool before
making any adjustments, changing accessories,
or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool
accidentally.
•Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
•Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tool´s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
•Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
•Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
Service
•Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power tool
is maintained.
Always use common sense
It is not possible to cover every conceivable situation you
can face. Always exercise care and use your common
sense. If you get into a situation where you feel unsafe,
stop and seek expert advice. Contact your dealer, service
agent or an experienced user. Do not attempt any task
that you feel unsure of!
!
WARNING! Read all safety warnings and
all instructions. Failure to follow the
warnings and instructions may result in
electric shock, fire and/or serious injury.
IMPORTANT! Save all warnings and instructions for
future reference. The term ”power tool” in the warnings
refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

Basic working techniques
Wall saws (blade/wire)
The following can be operated using the control levers on
the remote control:
• Longitudinal feed, the dial guides the saw unit’s
movement along the rail.
• Arm feeding, the dial guides the pivot arm’s movement
for changing of the cutting depth.
• Rotation of the blade/wire, controls the blade/wire
speed. Back arrow button, is used as a double
command when starting the blade’s rotation. Start the
rotation of the blade/wire by holding the "back" button
in while turning the rotation control clockwise. The
rotation speed is controlled with a potentiometer.
• To switch off the blade/wire rotation, turn the blade
rotation control anti-clockwise back to its zero
position.
