Notes on Operation
Before starting work
Check that saw is properly assembled
and in good condition. Refer to
appropriate sections in the instruction
manual:
Check operation of chain brake,
–
front hand guard
Correctly mounted guide bar
–
Correctly tensioned chain
–
Smooth action of throttle trigger and
–
throttle trigger lockout – throttle
trigger must return automatically to
idle position.
Master Control lever / stop switch
–
must move easily to 0 or STOP.
Check that the spark plug boot is
–
secure – a loose boot may cause
arcing that could ignite combustible
fumes and cause a fire.
Never attempt to modify the controls
–
or safety devices in any way.
Keep the handles dry and clean –
–
free from oil and pitch – for safe
control of the chainsaw.
To reduce the risk of personal injury, do
not operate your saw if it is damaged or
not properly assembled.
Starting the Engine
Starting the saw in a tree is very
dangerous since the user may lose
control of the machine – risk of injury.
MS 192 T, MS 192 TC
The tree surgery saw should be
checked, fueled, started and warmed up
by an assistant on the ground before it is
transported up to the operator in the
tree.
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The cutting attachment must
be clear of the ground and all other
obstructions because it may begin to run
when the engine starts.
The chainsaw is a one-person saw. Do
not allow other persons in the work area
– even when starting.
To reduce risk of chain rotation and
personal injury, lock the chain with the
chain brake before starting.
Do not attempt to start the saw when the
saw chain is in a cut.
During operation
When working in the tree, always secure
the chainsaw with a rope – tie it to the
ring and attach it to the lifeline. Always
engage the chain brake before letting
the chainsaw hang by the rope.
Make sure you always have good
balance and secure footing.
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the Master
Control / stop switch to 0 or STOP.
Your power tool is designed to be
operated by one person only. Do not
allow other persons in the work area.
Never leave a running power tool
unattended.
When the engine is running: Note that
the chain continues to rotate for a short
period after you let go of the throttle
trigger (flywheel effect).
Take special care in slippery conditions
– damp, snow, ice, on slopes, uneven
ground and freshly debarked logs.
Watch out for obstacles such as tree
stumps, roots and ditches which could
cause you to trip or stumble.
Do not work alone – keep within calling
distance of other persons trained in first
aid who can provide assistance in an
emergency. Helpers at the cutting site
must also wear protective clothing (hard
hat) and stand well clear of the branches
being cut.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
To reduce the risk of accidents, take a
break in good time to avoid tiredness or
exhaustion.
To reduce risk of fire, keep hot exhaust
gases and hot muffler away from easily
combustible materials (e.g. wood chips,
bark, dry grass, fuel). Mufflers with a
catalytic converter can become
particularly hot.
