Maintenance; Sharpening The Chain - EINHELL BG-CB 2041 T Mode D'emploi D'origine

Important!
•
Make sure that the chain tension is always
correctly adjusted.
•
Only use a chainsaw if it is in perfect working
order.
•
Only work with a saw chain that has been
properly sharpened in accordance with the
instructions.
•
Never cut with the upper edge or the tip of the
cutter bar.
•
Always hold the chainsaw firmly with both
hands.
Cutting wood which is under tension
Special care is required when cutting wood which
is under tension. Cutting wood which is under
tension can release the tension, causing the
wood to react out of control. In the worst case this
can result in severe and even fatal injuries. This
type of work must be performed only by specially
trained persons.

9. Maintenance

9.1 Replacing the chain and cutter bar
The cutter bar needs to be replaced if
•
the guide groove of the cutter bar is worn.
Proceed as described in the section „Fitting the
cutter bar and the chain".
9.2 Checking the automatic chain lubrication
You should check the operation of the automatic
chain lubrication system on a regular basis in or-
der to guard against overheating and the damage
this can cause to the cutter bar and the chain.
Point the tip of the cutter bar at a smooth surface
(a board or a cut tree face) and allow the chain-
saw to run. If you see a growing oil stain on the
smooth surface, the automatic chain lubrication
system is working properly. If there is no clear oil
stain, please refer to the corresponding instruc-
tions in the section „Troubleshooting". If the in-
formation contained there still fails to remedy the
situation, please contact our service department
or another similarly qualifi ed workshop.
Important! Do not actually touch the surface with
the tip of the cutter bar when performing this test.
Keep a safe distance (approx. 20 cm).

9.3 Sharpening the chain

Working eff ectively with the chainsaw is only pos-
sible if the chain is in good condition and sharp.
This also reduces the risk of kickback.
The chain can be re-sharpened by any dealer. Do
not attempt to sharpen the chain yourself unless
you have the necessary special tools and expe-
rience.
9.4 Maintenance of the air fi lter (Fig. 24-26)
Soiled air fi lters reduce the engine power by
supplying too little air to the carburetor. Regular
checks are therefore essential. The air fi lter (T)
should be checked after every 25 hours of use
and cleaned if necessary. If the air contains a
lot of dust, the air fi lter should be checked more
frequently.
1. Remove the air fi lter cover (Fig. 24).
2. Remove the air fi lter (Fig. 25/26).
3. Clean the air fi lter by tapping it or blowing it
out.
4. Assemble in reverse order.
Important: Never clean the air fi lter with petrol or
infl ammable solvents.
9.5 Maintenance of the spark plug (Fig. 27)
Spark plug sparking gap = 0.6mm. Tighten the
spark plug with a torque of 12 to 15 Nm. Check
the spark plug for dirt and grime after 10 hours of
operation and if necessary clean it with a copper
wire brush. Thereafter service the spark plug after
every 50 hours of operation.
1. Pull out the spark boot plug (Fig. 13).
2. Remove the spark plug (Fig. 27) with the sup-
plied multifunction tool (27).
3. Assemble in reverse order.
9.6 Carburetor settings
Important! Settings on the carburetor may only
be made by authorized customer service person-
nel.
The air fi lter cover must be removed before car-
rying out any work on the carburetor, as shown in
Fig. 24 and 25.
