Husqvarna K 770 Operator's Manual page 21

• Never cut asbestos materials!
• Hold the saw with both hands; keep a firm grip with
thumbs and fingers encircling the handles. The right
hand should be on the rear handle and the left hand
on the front handle. All operators, weather right or left
handed shall use this grip. Never operate a power
cutter holding it with only one hand.
• Stand parallel to the cutting blade. Avoid standing
straight behind. In the event of a kickback the saw will
move in the plane of the cutting blade.
• Maintain a safe distance from the cutting blade when
the engine is running.
• Never leave the machine unsupervised with the motor
running.
• Never move the machine when the cutting equipment
is rotating. Make sure that the blade has come to a
complete stop before the machine is put on the
ground. The machine is equipped with a friction
retarder to shorten the blade stop time.
• The guard for the cutting equipment should be
adjusted so that the rear section is flush with the work
piece. Spatter and sparks from the material being cut
are then collected up by the guard and led away from
the user. The guards for the cutting equipment must
always be fitted when the machine is running.
• Never use the kickback zone of the blade for cutting.
See instructions under the heading "Kickback".
• Keep a good balance and a firm foothold.
• Never cut above shoulder height.
OPERATING
• 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 blade is not in contact with anything
when the machine is started
• Apply the cutting blade gently with high rotating speed
(full throttle) Maintain full speed until cutting is
complete.
• Let the machine work without forcing or pressing the
blade.
• Feed down the machine in line with the blade.
Pressure from the side can damage the blade and is
very dangerous.
• Move the blade slowly forwards and backwards to
achieve a small contact area between the blade and
the material to be cut. This reduces the temperature of
the blade and ensures effective cutting.
Managing dust
The machine is fitted with a low flushing water kit that
offers maximum dust suppression.
Use wet cutting blades with water cooling when possible
for optimal dust management. See instructions in the
section "Cutting blades".
Adjust the water flow using the valve to bind the cutting
dust. The volume of water required varies depending on
the type of job at hand.
If water hoses loosen from their supply sources, this
indicates that the machine is connected to a water
pressure that is too high. See instructions under the
"Technical data" heading for recommended water
pressure.
