SAFETY INSTRUCTIONS

Diamond chains

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.

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.

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! Chain breakage can result in 
serious injury if the chain is thrown towards 
the operator.

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.

!

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.
