Look out for leaks! Never start the
engine if fuel has been spilled or is
leaking – Fatal burns may result!
2.8
Before Starting Work
Check that your saw is properly assembled and
in good condition – refer to appropriate chapters
in the instruction manual.
–
Check the fuel system for leaks, paying spe‐
cial attention to visible parts such as the tank
cap, hose connections and the manual fuel
pump (on machines so equipped). If there are
any leaks or damage, do not start the engine –
risk of fire. Have your saw repaired by a serv‐
icing dealer before using it again.
–
Check operation of chain brake, front hand
guard
–
Correctly mounted guide bar
–
Correctly tensioned chain
–
The trigger and trigger lockout must move
freely and spring back to the idle position
when they are released.
–
Master Control lever must move easily to
STOP, 0 or
†
–
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 dirt – for safe control of the saw.
–
Make sure there is sufficient fuel and chain oil
in the tanks.
To reduce the risk of personal injury, do not
operate your saw if it is damaged or not properly
assembled.
2.9
Starting the chain saw
Always work on a level surface. Ensure a firm
and secure footing. Hold the machine securely –
the chain must not touch any objects or the floor
– danger of injury due to the rotating saw chain.
Your chain saw is a one-person saw. Do not
allow other persons to be in the working area –
not even while starting.
Do not start the chain saw if the chain is in a cut.
Move at least 3 meters away from the place
where the machine was refuelled and never start
the motor in enclosed spaces.
Lock the chain with the chain brake before start‐
ing – risk of injury due to rotating chain!
Do not drop-start the engine – start as described
in the Instruction Manual.
2.10
During operation
Ensure you always have a firm and safe footing.
Take special care when the bark is wet – danger
of slipping!
001BA087 LÄ
Always hold the chain saw firmly with both
hands: Right hand on the rear handle – even if
you are left-handed. To ensure reliable control,
wrap your thumbs tightly around the handlebar
and handle.
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the Master Control lever / stop switch to
STOP, 0 or
†
.
Never let the machine run unattended.
Exercise caution with slippery surfaces, water,
snow, ice, steep slopes, uneven ground or green
wood that has just been stripped of its bark –
danger of slipping!
Use caution with tree stumps, roots, ditches –
danger of stumbling!
Do not work alone – keep within calling distance
of others who are trained in emergency proce‐
dures and can provide help in an emergency.
Helpers at the cutting site must also wear protec‐
tive clothing (helmet!) and stand well clear of the
branches being cut.
More care and attention than usual are required
when wearing ear protection, as warning sounds
(shouts, beeps, etc.) cannot be heard properly.
Take a break in good time to avoid tiredness or
exhaustion – risk of accidents!
Dust (e. g., sawdust), fumes and smoke pro‐
duced while using the machine may be hazard‐
ous to health. If dust is generated, wear a dust
mask.
