General
WARNING! Chain breakage can result in
!
serious injury if the chain is thrown
towards the operator. Faulty cutting
equipment or the wrong combination of
bar and chain increases the risk of
kickback! Use only the bar and chain
combinations that we recommend.
WARNING! Always disconnect the power
!
cable to the saw unit before installation,
cleaning and maintenance. Carelessness
can result in serious personal injury or
even death.
WARNING! Always wear gloves, when
!
working with the chain.
A) Drive link with bumper
B) Cutting link with diamond segment
C) Chain guide

Diamond chain pitch: Pitch=D/2
This unit must only be used with a double bumper chain
since the machine can be operated in double rotation
directions.
When using a chain with double bumpers, the chain can
be fitted either way round.
Check the chain
•
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. If the diamond chain is
damaged replace it.
•
If the chain has been exposed to hard jamming or
other abnormal overloading, the chain should be
dismantled from the bar for careful inspection.
Check the saw
The saw is equipped with a number of safety features that
protect the operator in the event of chain breakage. These
safety features must be checked before work starts.
Never use the saw if any of the following parts are
damaged or missing:
DIAMOND CHAINS

•
Transmission cover
•
Damaged chain
•
Damaged or missing spray guard.
Material
WARNING! Under no circumstances may
!
the diamond chain saw be converted to
cut other materials than those it is
intended for. It must never be equipped
with a timber/wood saw chain.
This machine is designed for and intended for sawing
concrete, brick and different stone materials. All other use
is improper.
The saw must never be used to cut pure metals. This will
probably result in broken segments or chain breakage.
The diamond segment can cut reinforced concrete. Try to
cut the reinforcement together with as much concrete as
possible, this will save the chain.
Glazing
After cutting extremely hard concrete or stone the
diamond segment may lose some or all of its cutting
capacity. This can also occur if you are forced to cut with
a low partial pressure (the diamond chain runs against the
workpiece along the entire length of the bar). The solution
to the problem is to change the rotation direction of the
chain.
Transport and storage
•
After completed work, the diamond chain saw shall be
run with water pressure for at least 15 sec. to clean
bar, chain and drive mechanism of particles. Rinse the
machine with water. If the machine is not to be used
for a while, we recommend oiling the chain and bar to
prevent corrosion.
•
Inspect all cutting equipment for transport and storage
damage.
