Tensioning The Saw Chain; Operation; Connecting To The Mains Supply; Switching On/Off - EINHELL GH-EC 2040 Manual De Instrucciones

5.2 Tensioning the saw chain

Warning! Always disconnect the mains plug
before performing any checks or adjustments. Al-
ways wear protective gloves when working on the
chainsaw to protect yourself against injury.
•
Undo the fixing screw of the chain wheel co-
ver a few turns (Fig. 4).
•
Adjust the chain tension with the chain ten-
sioning screw (Fig. 8). Turning the screw
clockwise increases the tension, turning it
counter-clockwise decreases the chain ten-
sion. The saw chain is correctly tensioned if it
can be lifted around 3-4 mm in the middle of
the cutter rail (Fig. 9).
•
Tighten the fixing screw of the chain wheel
cover.
Danger! All of the chain links must lie proper-
ly in the guide groove of the cutter rail.
Notes on tensioning the chain:
The saw chain must be properly tensioned to
ensure safe operation. You can tell that the chain
tension is perfect if the saw chain can be lifted
by around 3-4 mm in the middle of the cutter rail.
As the saw chain heats up during cutting and
thus changes in length, please check the chain
tension every 10 minutes and adjust it again as
required. This applies in particular to new saw
chains. When you have fi nished working slacken
the chain again, as the chain will shorten when it
cools down. This will prevent the chain from being
damaged.
5.3 Saw chain lubrication
Warning! Always disconnect the mains plug
before performing any checks or adjustments. Al-
ways wear protective gloves when working on the
chainsaw to protect yourself against injury.
Notice! Never operate the chain if it is not lub-
ricated with saw chain oil. Use of the chainsaw
without saw chain oil or if the oil level is below
the "min" mark (Fig. 10/ Item B) will damage the
chainsaw.
Notice! Be aware of the temperature conditions:
diff erent lubricants with completely diff erent
viscosities are required at diff erent ambient tem-
peratures. At lower temperatures you will need
low viscosity oils in order to achieve a suffi cient
lubricating fi lm. However, if the same low viscosity
oil is used during the summer it will become even
thinner due to the ambient temperatures alone,
and as a result the lubricating fi lm could break
down, causing the chain to overheat and become

damaged. In addition, the chain oil would burn
and produce unnecessary pollutants.
Filling the oil tank:
•
Place the chainsaw on a flat surface.
•
Clean the area around the oil tank cover (Fig.
10/Item A) and then clean the oil tank cover.
•
Fill the tank with saw chain oil. In the process,
make sure that no dirt enters the tank, as this
could cause the oil nozzle to become blo-
cked.
•
Close the oil tank cover.

6. Operation

6.1 Connecting to the mains supply

•
Connect the power cable to a suitable ex-
tension cable. Make sure that the extension
cable is designed for the power rating of the
chainsaw.
•
Secure the extension cable as shown in Fig.
12 to protect it against pulling forces and ac-
cidental disconnection.
•
Connect the extension cable to a professio-
nally installed safety mains outlet with ground
contact.
We recommend using a cable with a bright and
highly visible color, e.g. red or yellow. This will
reduce the risk of accidentally damaging it with
the chainsaw.
6.2 Switching on/off
Switching on
•
Hold the chainsaw by the handles with both
hands as shown in Fig. 13 (thumbs under the
handles).
•
Press and hold the safety lock-off (Fig. 1/Item
5).
•
Switch on the chainsaw at the ON/OFF
switch. You can then release the safety lock-
off.
Switching off
Release the ON/OFF switch (Fig. 1/Item 6).
The integrated brake will bring the running chain-
saw to a standstill within a very short space of
time. Always disconnect the mains plug when you
stop working, even if it is only for a short time.
