Checking And Adjusting The Chain Lubrication; Checking The Chain Brake; Basic Working Procedures When Felling Trees - Scheppach 5910114903 Originalbetriebsanleitung

9.2.2 Normal sequence
• Release the throttle control (10). The engine idles.
• Then switch the On/Off switch (6) to "OFF".
9.3 Operating while idle
m CAUTION
When idling, the saw chain (17) should not move.
If the saw chain (17) moves, you need to adjust the
idling speed!
NOTE
If the saw chain (17) moves when it is idling or the en-
gine goes out when you release the throttle, you need
to adjust the carburettor (see section "Maintaining the
carburettor settings").
• Lift the chainsaw.
• Hold the front handle (2) firmly in your left hand.
• Hold the rear handle (11) firmly in your right hand.
The ball of your hand now lies on the throttle control
lock (9) and your index finger operates the throttle
control (10) (see fig. E).
• After pulling the throttle (10), once, the engine
should idle.
• Run the engine to warm it up.

9.4 Checking and adjusting the chain lubrication

m CAUTION
• Never work without chain lubrication! If the saw
chain runs dry, the cutting equipment may become
irreparably damaged in a short time.
• Always check chain lubrication before starting
work.
Note
Use only saw chain oil preferably biodegradable. Do
not use waste oil, motor oil, etc.
While working, check whether the chain lubrication is
working correctly.
With the chainsaw running at a medium speed, hold it
over a sawn off tree stump or a suitable ground sheet.
If the lubrication is adequate, a light film of oil will form
on the tree stump or the ground sheet (see fig. F).
• If required, the chain lubrication can be increased
or decreased using the oil adjusting screw (19).
• To do this, use the supplied flat-head screwdriver
(31):
- Press and then turn the oil adjusting screw (19)
clockwise to decrease the chain lubrication.
- Press and then turn the oil adjusting screw (19)
anticlockwise to increase the chain lubrication.

9.5 Checking the chain brake

m WARNING
You must check the chain brake before every use.
The chain brake stops the saw chain in the event of
a kickback.
• Make sure that the front hand guard (1) is free of dirt
and moves freely.
• Start the chain saw and accelerate the saw chain
to full speed.
• With the saw chain running, press the front hand
guard (1). The chain brake must slow down and
lock the saw chain at maximum speed.
m WARNING
High engine revs over a long period with the engine
brake engaged will damage the engine and the chain
drive.
If the saw chain (17) moves anyway, contact Custom-
er Service.
10. Basic working procedures
when felling trees
m WARNING
Risk of injury!
Sawing and felling work as well as all associated
tasks may only be carried out by properly trained op-
erators.
Note
Note your country's laws regarding felling work and
contact the appropriate authority for more informa-
tion.
• Make sure that no one can be injured by falling
branches and trees.
• Only the required personnel should be in the work-
ing area.
• Keep the area around the trunk free and tidy to en-
sure secure footing for the operators.
• Keep all escape routes free and tidy to ensure that
the working area can be evacuated quickly.
• Do not carry out any felling work in strong wind,
poor weather or bad visibility.
• Keep a distance of at least 2½ tree lengths from
next working area.
10.1 Use and handling
• Never start the appliance before the guide rail (16),
saw chain (17) and sprocket cover (22) have been
fitted correctly.
• Do not cut any wood that is lying on the ground and
do not attempt to saw roots that are protruding from
the soil. Never immerse the saw chain (17) in the
soil, as this could blunt the saw chain (17).
