General Working Instructions - Husqvarna K960 Operator's Manual

Throttle lockout
• Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
• Press the throttle lockout and make sure it returns to its
original position when you release it.
• Check that the throttle control and throttle lockout move
freely and that the return springs work properly.
• Start the diamond chain saw and apply full throttle.
Release the throttle control and check that the chain stops
and remains stationary. If the chain rotates when the
throttle control is in the "IDLE POSITION" you should
check the carburettor's "IDLE ADJUSTMENT". See
instructions under the heading Maintenance.
SAFETY INSTRUCTIONS

General working instructions

WARNING! This section describes basic
!
safety directions for using the machine. This
information is never a substitute for
professional skills and experience. If you get
into a situation where you feel unsafe, stop
and seek expert advice. Contact your dealer,
service agent or an experienced power
cutter user. Do not attempt any task that you
feel unsure of!
Water cooling
Water cooling must always be used. Dry cutting causes
immediate overheating and bar and chain failure with a risk of
personal injury.
In addition to cooling the bar and chain, the flow of water
pushes particles away from the bar and the drive links. As a
result it is important with a high water pressure. The water
pressure should be at least 2.5 bar and a maximum of 11 bar.
The recommended pressure is approx. 5 bar.
WARNING! Water cooling, which is used
!
when cutting concrete, cools the blade and
increases its service life while also reducing
the formation of dust. Disadvantages include
difficulties at very low temperatures, the risk
of damaging floors and other structural
elements, and the risk of slipping.
Cutting technique
The technique described below is of a general character.
• Support the work piece in such a way that it is possible to
predict what will happen, and so that the cut remains open
while cutting.
• Always hold the machine in a firm grip with both hands.
Hold it so that the thumbs and fingers grip round the
handles.
• Start cutting with the machine running at maximum
speed.
• Start cutting gently, do not force or squeeze the chain in.
Always cut at maximum speed.
• Under normal conditions the machine should run at full
throttle. The feed pressure is adjusted so that the speed
drops to approx. 20–30 % under maximum speed; this
gives the best cutting efficiency and economy.
