Diamond Chains; General; Check The Chain; Check The Saw - Husqvarna K970 IIl Chain Operator's Manual

General

WARNING! Chain breakage can result in
!
serious injury if the chain is thrown
towards the operator.
Faulty cutting equipment or the wrong
combination of bar and diamond chain
increases the risk of kickback! Use only
the bar and diamond chain combinations
that Husqvarna recommend.
There are two basic types of diamond chain available on
the market.
B
C
A) Drive link with raker
B) Cutting link with diamond segment
C) Drive link without raker
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.

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.

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

Material

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.
This machine is designed for and intended for sawing
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.

Transport and storage

• After completed work, the diamond chain saw shall be
run with water pressure for at least 15 sec. to clean
bar, chain and drive mechanism of particles. Rinse the
machine with water. If the machine is not to be used
for a while, we recommend oiling the chain and bar to
prevent corrosion.
• Inspect all cutting equipment for transport and storage
damage.
