Husqvarna K970 II Chain Operator's Manual page 16

• Maintain a safe distance from the cutting chain when
the engine is running.
• Never leave the machine unsupervised with the motor
running.
• Never move the machine when the cutting equipment
is rotating.
• Never use the kickback zone of the bar for cutting.
See instructions under the heading "Kickback".
• Keep a good balance and a firm foothold.
• Never cut above shoulder height.
• Never cut from a ladder. Use a platform or scaffold if
the cut is above shoulder height. Do not overreach
• Stand at a comfortable distance from the work piece.
• Check that the cutting equipment is not in contact with
anything when the machine is started.
• Apply the chain gently with high rotating speed (full
throttle) Maintain full speed until cutting is complete.
• Let the machine work without forcing or pressing the
chain.
• Feed down the machine in line with the bar and cutting
chain. Pressure from the side can damage the bar
and the cutting chain and is very dangerous.
• Move the cutting chain slowly backwards and
forwards to give a small contact surface between the
cuttinga chain and material to be cut. This will mean
the cutting blade temperature is kept down resulting in
efficient cutting.
In principle there are two ways to start the process of
entering a thick object to be cut.
16 – English
OPERATING
Plunge-cut method
• Start by making a 10 centimetre deep cut in the wall
using the lower part of the tip of the bar. Straighten up
the saw at the same time as the tip of the bar is
inserted in the slot. Raising and lowering the saw at
the same time as it is pressed into the wall provides
an effective method of cutting to the full depth.
Pilot method
!
This method is recommended when attempting to cut
absolutely straight and square.
For best cutting economy, pre-cut with a power cutter
equipped with Husqvarna's special pre-cutting blade
intended for further cutting with diamond chain saw.
• Start by securing a board where the cut is to be made.
This serves as a guide for the cut. Cut to a depth of a
few centimetres along the entire line, using the lower
section of the tip of the bar. Go back and cut another
few centimetres. Repeat until a depth of between 5–
10 centimetres is reached, depending on precision
demands and the thickness of the object. The pilot cut
guides the bar straight during continued cutting, which
takes place according to the plunge-cut method until
full depth is reached, use the hand guard as a break
point/stop.
WARNING! Never use a power cutter with
a standard cutting blade for pilot cutting.
The cutting blade produces a pilot slot
that is too thin and continued cutting
with the diamond chain saw results
infallibly in dangerous kickback and
jamming in the slot.
