Before Starting The Equipment; Tensioning The Saw Chain - EINHELL GC-EC 7520 T Originalbetriebsanleitung

Caution!
Residual risks
Even if you use this electric power tool in
accordance with instructions, certain resi-
dual risks cannot be rules out. The following
hazards may arise in connection with the
equipment's construction and layout:
1. Cut injuries are possible if no safety clothing
is used.
2. Lung damage if no suitable protective dust
mask is used.
3. Damage to hearing if no suitable ear protec-
tion is used.
4. Health damage caused by hand-arm vib-
rations if the equipment is used over a pro-
longed period or is not properly guided and
maintained.

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 electric pole pruner
to the power supply until it has been fully assem-
bled and the chain tension has been adjusted. To
protect yourself against injury, always wear pro-
tective gloves when working on the electric pole
pruner. Carefully unpack all parts and check that
they are complete (Fig. 2).
5.1 Fitting the shoulder strap
Fig. 3a/3b: Hook the carry strap with safety
release onto the shoulder strap holders (Item
4a/4b).
5.2 Fitting the cutter rail and saw chain
•
Lay the saw chain as shown in the groove
which runs around the cutter rail (Fig. 4/Item
A).
•
Insert the cutter rail (13) and the saw chain
(12) in the mounting of the electric pole pru-
ner (Fig. 5) as shown. At the same time guide
the chain around the sprocket wheel (Fig. 5/
Item B).
•
Attach the chain wheel cover (Fig. 6/Item 14)
and fasten it hand-tight with the fastening
screw (Fig. 6/Item 14a).

Important! Do not fully tighten the fastening
screw until after you have adjusted the chain ten-
sion (see section 5.3).

5.3 Tensioning the saw chain

Warning! Always disconnect the mains plug
before performing any checks or adjustments. To
protect yourself against injury, always wear pro-
tective gloves when working on the electric pole
pruner.
•
Slacken the fastening screw (Fig. 6/Item 14a)
of the chain wheel cover by several turns
(counter-clockwise).
•
Set the chain tension with the chain tensi-
oning screw (Fig. 7/Item 14b). Turning the
screw clockwise increases the chain tension,
turning it counter-clockwise decreases the
chain tension. The chain tension is correct
when the chain can be lifted by about 2 mm at
the center of the cutter rail (Fig. 8).
•
Tighten the fastening screw (Fig. 6/Item 14a)
for the chain wheel cover (clockwise).
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. To
protect yourself against injury, always wear pro-
tective gloves when working on the electric pole
pruner.
Important! Never operate the chain if it is not
lubricated with saw chain oil. Use of the electric
pole pruner without any saw chain oil or with the
oil level below the fi ll-level window will result in
damage to the electric pole pruner.
