SAFETY INSTRUCTIONS
Diamond chains
CUTTING EQUIPMENT
CAUTION! Chain breakage can result in serious injury if
the chain is thrown towards the operator.
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 saw 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 cut in a soft
abrasive material such as sandstone or brick, for a short while.
Use the saw the right way up
For reasons of safety the saw must never be used upside down.
Parts worn loose from the cut object or damaged chain parts
can be thrown towards the operator.
Do not cut any material other than what the machine
is intended for
The diamond chain saw is only intended for cutting concrete,
stone, brick and similar material. 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.
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 chain has been exposed to hard jamming or other
abnormal overloading, the chain should be dismantled from the
bar for careful inspection.
Fit the chain the right way round
The chain must never be fitted the wrong way round. The raker
should guide the segment at the right height in the cut.
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:
– Cover over drive gear
– Damaged or missing hand guard
– Damaged chain
There are two basic types of diamond chain available on the
market. The difference between these is whether the chain has
rakers on just one side of the diamond segment or on both
sides. When using a chain with one raker, the chain should
always be fitted the right way round, i.e. the raker should guide
the segment at the right height in the cut. When using a chain
with double rakers, the chain can be fitted either way round.
CAUTION! If the chain has been used and is refitted it must be
fitted in the same working direction as earlier in order to reduce
segment wear and to obtain full cutting capacity directly.
