Before Starting The Equipment; Tensioning The Saw Chain - EINHELL GC-EC 750 T Manual De Instrucciones Original

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.
Warning! 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.
Carefully unpack all parts and check that they are
complete (Fig. 1).
5.1 Mounting the additional handle
(Fig. 2, 2a)
The additional handle consists of the grip (L),
counterpart (M) and 4 screws (F).
Push the handle (L) over the grip (Fig. 1/Item 2)
and the shoulder strap attachment (E). Place
the counterpart on the fi xed tube (6) above the
shoulder strap attachment (E) and screw the grip
(L) to the counterpart from underneath using 4
screws (F).
After loosening the 4 screws (F), you should be
able to push the additional handle (Fig. 1/Item
5) on the fi xed tube to suit your requirements.
Then tighten the 4 screws (F) again so that the
additional handle (Fig. 1/Item 5) is again attached
securely to the fi xed tube (6).
5.2 Assembly of the cutter rail and the saw
chain
•
Undo the fixing screw of the chain wheel co-
ver (Fig. 3).
•
Take off the chain wheel.
•
Lay the chain as shown in the groove which
runs around the cutter rail (Fig. 4/item A).
•
Insert the cutter rail and chain as shown in
the mounting in the chainsaw (Fig. 5). At the
same time guide the chain around the chain
wheel (Fig. 5/Item B).
•
Attach the chain wheel cover and fasten it by
hand with the fixing screw (Fig. 6/Item C).
Important! Do not fully tighten the fi xing screw
until after adjusting the chain tension (refer to
point 5.3).

5.3 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. 3).
•
Adjust the chain tension with the chain tensi-
oning screw (Fig. 7/Item D). 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 2 mm in the middle of the
cutter rail (Fig. 8).
•
Tighten the fixing screw (C) of the chain
wheel cover (Fig. 6).
Important! All of the chain links must lie properly
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 2 mm in the middle of the cutter rail. As
the saw chain heats up during cutting and thus
changes in length, check the chain tension no
less than 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.
5.4 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 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
