Before Starting The Equipment; Tensioning The Saw Chain - EINHELL GH-EC 2040 Originalbetriebsanleitung

5. Before starting the equipment

Before you connect the equipment to the mains
supply make sure that the data on the rating plate
are identical to the mains data.
Warning!
Always pull the power plug before making
adjustments to the equipment.
Caution: Do not connect the chainsaw to the po-
wer supply until it has been fully assembled and
the chain tension has been adjusted. Always wear
protective gloves when working on the chainsaw
to protect yourself against injury.
5.1 Assembly of the cutter rail and the saw
chain
•
Carefully unpack all parts and check that they
are complete (Fig. 2-3).
•
Undo the fixing screw of the chain wheel co-
ver (Fig. 4).
•
Take off the chain wheel (Fig. 5).
•
Lay the chain as shown in the groove which
runs around the cutter rail (Fig. 6/Item A).
•
Insert the cutter rail and chain as shown in
the mounting in the chainsaw (Fig. 6). At the
same time guide the chain around the chain
wheel (Fig. 6/ Item B).
•
Attach the chain wheel cover and secure it
with the fixing screw (Fig. 7). Caution: Do not
fully tighten the fixing screw until after adjus-
ting the chain tension (refer to point 5.2).

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.
