Adjustment of the chain tension:
1. First, slightly tighten the locking screw on the sprocket cover.
2. The screw of the clamping device (g) is located below the chain link on the
front of the device head. Use the supplied spark plug wrench (22) to turn it in
the appropriate direction to increase or decrease the tension on the chain.
Turning clockwise: Tension of the chain is increased.
Turning counterclockwise: Tension of the chain is relaxed.
AA correct chain tension can be detected by the fact that the saw chain rests
evenly at each point of the blade unit and does not sag or overstress.
3. If the chain tension is correct, retighten the sprocket cover lock knob. New
chains expand. Check the new chain after a few minutes of operation. Let the
chain cool down and then adjust the chain tension again if necessary.
Fill in oil:
The prerequisite for perfect function and long product life is regular
lubrication. Therefore check the oil tank every time before using this device
and refill with oil if necessary. Proceed as follows:
1. Open the cap of the oil tank (28). Remove oil residue and other contaminants
by rubbing the filler cap and oil filler neck with a cloth.
2. Fill environmentally friendly and biodegradable chain lubricating oil into the
oil tank (28) and then close it again. To minimize the risk of fire, make sure that
there are no oil residues outside the container when filling. Always use a funnel
to fill.
Never use waste oil for chain lubrication.
Used oil does not have the necessary lubricating properties, is harmful to
the environment and causes skin cancer after prolonged and repeated skin
contact. Use only lubricating oil, which has sufficient resistance to aging so
that it does not become resinous and form solid deposits that could damage
the device.
Always adhere to the specified oil intervals. This device must be re-supplied
with oil after a working time of max. 15 minutes.
Adjustment of flow of the oil
Caution:
An increase in oil throughput speeds up oil consumption, leading to more
frequent checks / refills.
To ensure adequate lubrication, it may be necessary to check the oil level more
frequently than when refilling the fuel tank.
The guide rail and the chain are automatically lubricated by a pump that works
when the chain turns.
The pump is factory set to provide a medium flow rate. However, it can be
set in the field. Temporary increase in oil flow is often desirable when cutting
hardwood and resinous wood.
Set the pump as described below:
1. Stop the engine and make sure the stop switch is in the "STOP" position.
2. Place the device on the side with the oil tank on top. See the image A10.
3. Using a screwdriver, turn the adjusting screw of the oil-throughput in the
desired direction
. In the clockwise direction : Reduce lubrication
. Counter-clockwise: Increase lubrication
Caution:
The adjusting screw of the oil flow must be pressed slightly while turning,
otherwise the pump and screw will be damaged.
