1. Put on the shoulder strap (20).
2. Adjust the strap length
3. Hang the device to the snap hook of the
shoulder strap.
4. Let the machine swing.
- The cutting tool may just about touch the
ground during normal work posture.
ATTENTION! In the event of an emergency, the
secure-fit tab can be pulled out at the shoulder
strap. The machine will then be immediately
released from the shoulder strap (20) and falls to
the floor.
8.4 Installation of chain-saw
Your new chain saw requires an adjustment of
the chain and filling of the lubrication oil tank
with the lubricating oil before the device is ready
for operation. Do not keep the saw’s engine on as
long as the the device is not properly prepared.
Read all instructions carefully.
Do not install any other rail or chain as the one
recommended for the model.
8.4.1 The guide bar and chain assembly(B7-11)
1. First remove the chain guard from the blade
unit.
2. Then rotate the locking screw on the cutting
head with the wrench and remove the upper
housing cover.
3. Set the saw chain into the groove guide of the
blade unit, Start as far as possible at the blade's
top edge.
4. Place the saw chain around the chain sprocket
and set the blade unit on the bolt of the tension
slide . Make sure that the bolt intervenes in the
corresponding opening on the blade.
5. If necessary, turn the screw on the tensioner. So
that a uniform wear of the chain blade is ensured,
the the chain blade should be rotated after 8 - 10
working hours.
Make sure that there is always a correct tension of
the chain and check them before each use of the
device. A loose chain could get loosened from
the guide groove of the blade unit and cause
serious injury. Further a loose chain also increases
the danger of a backlash. In addition, the blade ,
chain and chain sprocket get worn out faste
8.4.2 Adjustment of the chain stretching (B8)
1. First turn the locking screw at the sprocket
cover slightly.
2. Below the chain blade, the screw of the
tensioner is located on the front side of the
head of the device. Turn this with the help of
the wrench, in the corresponding direction, to
increase and/ or loosen the tension of the chain.
Turn in clockwise direction: Chain tension is
increased.
Rotate counter-clockwise: Tension of the chain is
loosened.
A correct chain tension can be recognized
through the saw chain resting at every point of
the blade unit uniformly and does not sag or is
not too strongly tensed.
3. If the chain tension is correctly set, tighten the
locking knob of the chain sprocket cover again.
New chains stretch out. Check the new chain
after a few minutes of the operation. Let the
chain to cool down and then, if necessary, set the
chain tension again.
8.4.3 Fill the oil tank (B12)
The prerequisite for a proper function and a long
product life cycle is a regular lubrication. You
should therefore check the oil tank in this device
before each start-up and fill oil as required.
Proceed as follows:
1. Open the cap of the oil reservoir. Remove oil
residues and other impurities by wiping the tank
cap and the oil filler neck with a cloth.
2. Fill in environmentally-friendly and
biodegradable chain lubricant oil in the oil
reservoir and plug it back subsequently. To rule
