Maintenance And Servicing; In The Case Of Technical Problems - Echo CS 2100 Operating Instructions Manual

• Do not remove free-hanging branches from below.
Felling a tree (Fig. 9 + 10)
• Ensure that no one is within the felling area, minimum
distance: 2 tree lengths.
• Ensure that no one can be hit by falling branches or
the tree to be felled.
• Ensure that there is an escape path as shown in Fig.
10.
• Ensure that you are standing firmly.
• Keep the working area free of objects.
• Always stand at the side of the tree during felling.
• First determine in which direction the tree is to be
felled. The felling notch is cut on this side of the
trunk.
• First cut 1/3 of the trunk diameter horizontally into the
tree at the intended felling notch.
• Now cut the second part of the felling notch from
above at an angle of 45° to the first cut.
• Now make the felling cut exactly opposite to the felling
notch. The felling cut must run horizontal and a bit
higher than the felling notch.
• Do not cut completely through the tree. Leave about
1/10 of the trunk diameter.
• Put wedges into the felling cut to bring the tree to fall.
Cutting a felling tree
• First support the trunk so that the section to be cut off
always hangs freely and does not lie on anything so
that the bar cannot jam.
• If the chain saw does become jammed, switch it off
immediately and withdraw the plug. Use the wedges
to free the bar.
• Avoid letting the saw chain coming into contact with
the earth.
General instructions on working with a chainsaw
• Ensure that children and other spectators keep a safe
distance from the working area.
• Apply little pressure to the machine when sawing
wood. If the chain is keen, it will cut almost by itself
through the wood.
• If possible, always work with the chainsaw running at
high speed.
• Never try to continue sawing with a blunt chain. That
causes the motor to overheat and the loss of your right
to claim under guarantee. Always have a replacement
chain at hand.
• Allow the motor to cool off and make working breaks.
• After use always place the chain saw horizontally to
avoid oil dripping from the oil reservoir.
• Always use the chain cover when transporting the
chain saw.

Maintenance and Servicing

Always withdraw the plug when carrying out
maintenance and servicing.
• Always remove wood shavings and oil from your chain
saw after use. Ensure in particular that the motor ven-
tilation slits for cooling the motor in the housing of the
chain saw is free (danger of overheating).
• If the saw chain is particularly dirty, e.g. in case of
gum-ming with resin, remove the chain and clean it.
Place the chain for a few hours in a vessel containing
chainsaw cleaner. There-after clean the chain with
clear water. If the chain is not used again immediately,
it must be treated with service spray or a customary
anticorrosion-spray.
• Only in case of use of biological oil: As some biological
oils may tend to incrustation after a time, the oiling
system should be rinsed thoroughly before storing the
chain saw for a longer period. Therefore, please fill
half of the oil reservoir (about 50 ml) with chainsaw
cleaner and close it as usually. Then switch on the
chainsaw - without bar and chain being mounted -
and keep it running until the total rinsing liquid has
evapurated through the oil opening of the chain saw.
Before using the chain saw again, it is absolutely
necessary to refill the oil reservoir.
• Do not store the saw outdoors or in damp and moist
areas.
• Check all the chain saw parts, in particular the chain,
bar and sprocket, of wear after every use.
• Ensure that the chain tension is correct. If the chain
is too loose, it may come off during use and lead to
injuries. The chain must be replaced immediately if it
is damaged. The cutting teeth must be at least 4 mm
long.
• Check the motor housing and power cable after every
use for damage. If there is any sign of damage, have
the chain saw checked by a specialised workshop or
the works after-sales service.
• Check the oil level and lubrication of your chain saw
after every use. Insufficient lubrication leads to dam-
age to the chain, bar and motor.
• Check how keen the chain is every time before you
use the chain saw. A blunt chain will cause overheating
of the motor.
• Sharpening a saw chain requires experience and spe-
cialised knowledge. We therefore recommend to have
sharpening carried out by a specialised workshop.

In the case of technical problems

• The machine does not start up: Check whether the
current socket is live. Check whether the power cable
is undamaged. If neither case applies, take the chain
saw to a specialised workshop or the works after-sales
service.
• Chain does not run: Check position of handguard
(see ill. 7). Chain only runs if handguard brake is re-
leased.
• Sparks fly at the motor: Motor or carbon brushes
damaged. Take the chain saw to a specialised work-
shop or the works after-sales service.
• Oil does not flow: Check the oil level. Clean the oil
flow openings in the bar (see also the corresponding
hints of "Maintenance and servicing). If this is not suc-
cessful, take the chain saw to a specialised work-shop
or the works after-sales service.
