Diamond chains
WARNING! Chain breakage can result in
!
serious injury if the chain is thrown towards
the operator.
There are two basic types of diamond chain available on the
market.
When using a chain with double rakers, the chain can be fitted
either way round. When using a chain with one raker, the
chain should always be fitted the right way round. The raker
should guide the segment at the right height in the cut.
IMPORTANT! 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.
A) Drive link with raker
B) Cutting link with diamond segment
C - Drive link without washer
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.

SAFETY INSTRUCTIONS
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
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.
Material
This machine is designed for and intended for cutting
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 cut
in a soft abrasive material such as sandstone or brick, for a
short while.
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.
