English Operating Instructions – Chain Saw with Combustion Engine
12
Attach the cover (17). The pin
(23) of the chain tensioner must
be in the opening (24) of the saw
rail.
Screw on the nuts (19) and
tighten them by hand.
Turn the adjusting screw for
chain tension (18) clockwise until
the chain is taut on the lower part
of the saw rail (2). In doing so,
pull the saw rail upwards by the
tip.
Tighten up the nuts (19).
Note
– The chain is correctly tensioned
when it can be lifted by 5 mm in
the middle of the saw rail.
– Always check the chain tension
each time before using
the chain
saw!
Running in the saw chain
During the running-in time retension
the saw chainafter a maximum of
five cuts.
Checking the tension of the
saw chain
The chain is correctly tensioned
when it can be lifted by 5 mm in the
middle of the saw rail.
If required, readjust the tension of
the saw chain (see section “Main
-
tenance and cleaning”).
Checking the chain brake
Fig. 7
The chain brake immediately blocks
the saw chain if a kickback occurs.
Position
A
of the chain brake (15):
Chain brake is activated.
Position
B
of the chain brake (15):
Operating position.
Manual actuation of the chain
brake (in an emergency):
Tilt the hand guard (3) towards
the saw rail tip.
Releasing the chain brake
(operating position):
Pull the hand guard (3) towards
the front handle until the hand
guard engages.
Before starting work with the chain
saw, check that the chain brake is in
perfect working order.
Place the device on the ground.
Start the device (see section
“Operation”).
Run engine at idling speed and
tilt the hand guard (3) towards
the saw rail tip.
Briefly depress throttle all the
way. The chain may not move!
Stop the engine (see Section
“Operation”).
If the chain brake does not function,
do not use the power tool. Contact a
service centre.
Caution!
Before starting work, release the
chain brake.
Fill with saw chain oil
Risk of damage to the device!
Never use old oil to lubricate the
saw chain! This can damage the oil
pump, saw rail and saw chain!
Damage to the environment!
As the saw chain oil is released into
the environment during operation,
special biodegradable, plant-based
saw chain oils should be used.
Fig. 8
Place the device securely on the
ground with the tank cap (16)
face up.
Before opening, clean the tank
cap and inlet nozzle if required.
Slowly unscrew the tank cap and
remove it.
Carefully pour in saw chain oil.
Do not spill any oil!
Tighten the tank cap by hand.
If any saw chain oil was spilled:
Wipe up the oil.
Checking the chain
lubrication
Do not use the chain saw without
adequate chain lubrication.
Inadequate lubrication will reduce
the service life of the device.
Check the amount of oil in the
tank.
Start the device (see section
“Operation”).
Hold the running saw chain for
some time approx. 15 cm above
a suitable surface.
If there is adequate chain lubrication,
the oil which is ejected by the saw
chain will form a light trail.
Note
The oil supply for lubrication of the
chain can be varied with the
adjusting screw (1, Fig. 21)
(depending on the model).
Oil and petrol
Oil
Only use high-quality oil, API
classification TC (TSC-3), which is
intended for air-cooled two-stroke
engines.
Mix the oil for two-stroke engines
according to the instructions on the
container, 1:40 (2.5 %).
Petrol
Danger
Under certain conditions petrol is
extremely flammable and explo
-
sive.
– Only refuel in a well ventilated
environment and with the engine
switched off. Do not smoke near
the tank or where fuel is stored
and extinguish all ignition sources.
– Do not overfill the fuel tank (there
may be any fuel in the inlet
nozzle). After refuelling, ensure
that the tank cap is closed and
secured.
– When refuelling, ensure that you
do not spill any fuel. Spilled fuel or
petrol vapours may ignite. If fuel
has been spilled, ensure that the
area has dried before restarting
the engine.
– Avoid repeated or prolonged skin
contact and vapour inhalation.
Instructions for mixing petrol
and oil
Old and/or incorrectly mixed fuel are
the main reasons for the power tool
is not running properly. Always use
clean, fresh unleaded petrol (no
more than 30 days old, minimum
octane number 91 ROZ). Do not
use fuel of specification E85.
Follow exactly the instructions for
the correct petrol/oil mixture.
Correctly mix two-stroke engine oil
and lead-free petrol, 1:40 (2.5 %).
Do not mix directly in the tank.
