Working Instructions - Zgonc YGL N.G. 2400 Originalbetriebsanleitung

Hold the guide bar (7) vertically with the tip pointing
upwards and put on the saw chain (4, beginning at the
tip of the bar:
• Place the guide bar with the saw chain on the chain
wheel (16) and guide bolt (17). Ensure that the ad-
justment plate (Fig.3/7A) is showing to you.
• Place the saw chain round the chain wheel (16).
Cause the chainsaw to the sprocket and check
whether it is correctly.
• The adjustment plate (7a) is fastened to the guide
rail (7) with the screw F.
• Place the cover (6) on top and tighten gently with the
lock nut (5).
Now the saw chain has to be correctly tensioned.
Tensioning the saw chain
m Warning!
Always pull the plug out of the power socket before
doing any work on the chainsaw!
Wear safety gloves!
• Make sure the saw chain (4) is inside the guide
groove of the guide bar (7).
• Turn the outer Knob (Fig. 3/5A) clockwise until the
saw chain is correctly tensioned, then rotate the in-
side knob (5) to block the guide bar in that position.
• While the inside knob is being tightened, the guide
bar must then be pushed upwards.
• Check the chain tension again. Do not tension the
chain too tightly.
• When cold, it should be possible to lift the chain in
the middle of the guide bar approx. 5 mm. Tighten
the lock nut (5) securely.
• When warm, the saw chain will expand and slacken
and there is a danger of it jumping off the rail alto-
gether. Re-tension if necessary.
• If the saw chain is re-tensioned when hot, it must
be loosened again when the sawing work has been
completed.
• Otherwise, the contraction which takes place as the
chain cools would result in excessively high tension.
• A new saw chain requires a running-in period of
approx .5 minutes. Chain lubrication is very impor-
tant at this stage. After running in, check chain ten-
sion and re-tension if necessary.

9. Working instructions

Transporting the chainsaw
Before transporting the chainsaw, always remove the
plug from the power socket and slide the chain guard
over the rail and chain. If several cuts are to be per-
formed with the chain saw, the saw must be switched
off between cuts.
Securing the extension lead
Only use extension leads suitable for outdoor use.
The cross section of the cable (max. length of exten-
sion cord: 75m) must be at least 1,5 mm². secure the
chainsaw flex to the extension lead by inserting the
extension lead into the strain relief gap of the housing
31 GB
(Fig..M).Extension leads longer than 30 m will reduce
the performance of the chainsaw.
Chain lubrication
To prevent excessive wear, the saw chain and guide
bar must be evenly lubricated during operation. Lubri-
cation is automatic. Never work without chain lubrica-
tion. If the chain runs dry, the entire cutting apparatus
will quickly become severely damaged.
It is therefore important to check both chain lubrication
and the oil gauge every use (Fig. 4).
Never use the saw when the oil level is below the
"Min." mark.
• Min.: When only approx. 5 mm of oil is visible at
the lower rim of the oil gauge (15), you must top up
with oil.
• Max.: Top up with oil until the window is full.
Chain lubricants
The service life of saw chains and guide bars depends
to a large extent on the quality of the lubricant used.
Old oil must not be used! Use only environment-
friendly chain lubricant. Store chain lubricant only in
containers which comply with the regulations.
Guide bar
The guide bar (7) is subjected to especially severe
wear and tear at the nose and the bottom. To avoid
one-sided wear and tear, turn the guide bar over every
time when you sharpen the chain.
Chain wheel
The chain wheel (16) is subjected to especially high
wear and tear. If you notice deep wear marks on the
teeth, the chain wheel must be replaced. A worn chain
wheel curtails the service life of the saw chain. Have
the chain wheel replaced by a specialist dealer or your
Customer Service.
Chain guard
The chain guard must be clipped onto the chain and
sword as soon as the sawing work has been complet-
ed and whenever the chainsaw has to be transported.
Chain brake
In the event of kick-back, the chain brake (3) will be
actuated via the front finger guard. The front finger
guard is pushed forwards by the back of the hand and
this causes the chain brake to stop the chain saw, or
rather the motor, within 0.15 s (Fig 5, H).
Releasing the chain brake (Fig 5)
To be able to use your chain saw again, you must re-
lease the saw chain again. First switch off the chain-
saw. Then push the front finger guard (3) back into the
vertical position until it locks in place (Fig 5, I). The
chain brake is now fully functional again.
