SAFETY INSTRUCTIONS
CUTTING EQUIPMENT
CAUTION! Chain breakage can result in serious injury if the chain is thrown towards the operator.
Diamond chains
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.
A)Drive link with raker
B)Cutting link with diamond segment
C)Drive link
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
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.
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.
