WARNING! This machine produces an
!
electromagnetic field during operation.
This field may under some
circumstances interfere with active or
passive medical implants. To reduce the
risk of serious or fatal injury, we
recommend persons with medical
implants consult their physician and the
medical implant manufacturer before
operating this machine.
Work area safety
WARNING! The safety distance for the
!
power cutter is 50 feet (15 metres). You
are responsible to ensure that animals
and onlookers are not within the working
area. Do not start cutting until the
working area is clear and you are
standing firmly.
• Observe your surroundings to ensure that nothing can
affect your control of the machine.
• Ensure that no one/nothing can come into contact
with the cutting equipment or be hit by parts thrown by
the diamond chain.
• Do not use the machine in bad weather, such as
dense fog, heavy rain, strong wind, intense cold, etc.
Working in bad weather is tiring and can lead to
dangerous conditions, e.g. slippery surfaces.
• Never start to work with the machine before the
working area is clear and you have a firm foothold.
Look out for any obstacles with unexpected
movement. Ensure when cutting that no material can
OPERATING
become loose and fall, causing injury to the
operator.Take great care when working on sloping
ground.
• Ensure that the working area is sufficiently illuminated
to create a safe working environment.
• Make sure that no pipes or electrical cables are routed
in the working area or in the material to be cut.
• If cutting into a container (drum, pipe, or other
container) you must first make sure it does not contain
flammable or other volatile material.
Water cooling and dust management
Water cooling must always be used. Dry cutting causes
immediate overheating and bar and chain failure with a
risk of personal injury.
In addition to cooling the bar and chain, the flow of water
pushes particles away from the bar and the drive links. As
a result it is important with a high water pressure. For
recommended water pressure and flow, see "Technical
data" section.
If water hoses loosen from their supply sources, this
indicates that the machine is connected to a water
pressure that is too high.
Wet cutting also provides adequate dust suppression.
Basic working techniques
!
• This machine is designed for and intended for sawing
concrete, brick and different stone materials. All other
use is improper.
• Check that the chain does not show signs of damage
in the form of play on the links, broken raker or drive
links or broken segments.
WARNING! Do not lean the saw to the
side, this can cause the chain to jam or
break with personal injury as a
consequence.
Under all circumstances avoid grinding
using the side of the bar and chain; it will
almost certainly be damaged, break and
can cause immense damage. Only use
the cutting section.
Before entering an existing slot made by
another blade, check that the slot is not
thinner than your blade as that may
result in binding in the cutting slot and a
kickback.
Never use diamond chains to cut plastic
material. The heat produced during
cutting may melt the plastic and it can
stick to the chain and cause a kickback.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
