1. e Inspect new cutting equipment for transport or storage damage Once the work has been completed the diamond chain saw should be run with water pressure for at least 15 seconds to clean particles from the bar chain and drive mechanism Rinse off the machine with water It is recommended that the chain and bar are oiled to prevent corrosion if it is not to be used for some time 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 abno2.
