The battery can be removed for immediate use. Continuous Lighting of the Green Battery Charge Indicator
Full Continuous lighting of the green battery charge indicator indicates that the battery is fully charged.
When the battery is not inserted, continuous lighting of the battery charge indicator indicates that the mains plug is
inserted in the socket outlet and that the battery charger is ready for operation.
Continuous Lighting of the Red Battery Charge Indicator Continuous lighting of the red battery charge indicator
indicates that the temperature of the battery is not within the allowable charging temperature range, see section
“Technical Data”. As soon as the allowable charging temperature range is reached, the battery charger
automatically switches to rapid charging.
Flashing Red Battery Charge Indicator A flashing red battery charge indicator indicates a different malfunction of the
charging procedure, see section “Troubleshooting – Causes and Corrective Measures”.
Charging Advice
With continuous or several repetitive charging cycles without interruption, the charger can warm up. This is not
meaningful and does not indicate a technical defect of the battery charger.
A significantly reduced working period after charging indicates that the battery is used and must be replaced.
Observe the notes for disposal.
Mounting and Tensioning the Chain Saw
Do not connect the chain saw to mains before it is completely assembled.
Always wear protective gloves when handling the chain.
Chain and chain bar assembly (see figures A1–A4)
Use only chains with a drive link thickness of 1.1 mm.
Unpack all parts carefully.
Place the chain saw on any suitable flat surface.
Slide the saw chain (12) in the slot around the chain bar (11). Ensure the saw chain is in the correct
running direction by comparing the saw chain with the rotation symbol.
Fit the chain links around the drive sprocket (20) and mount the chain bar (11).
Check if all parts are seated properly and hold the chain bar and the chain in this position.
Reattach the cover again (15).
Lightly tighten the cover (15) with the clamping knob (14).
The chain is not yet tensioned. The saw chain is tensioned as described in section “Tensioning the Saw
Chain”.
Tensioning the Saw Chain (see figure B)
Always check the chain tension before use, after the first cuts and regularly during use approx. every 10 minutes.
Upon initial operation, new chains can lengthen considerably.
The chain life of the saw chain mainly depends upon sufficient lubrication and correct tensioning. Avoid tensioning
the chain if it is hot, as this will cause the chain to become over tensioned and fit too tightly against the chain bar
when it cools down.
Place the chain saw on any suitable flat surface.
Turn clamping knob (14) approx. 1–3 turns anticlockwise to loosen the chain bar.
Check if the chain links are correctly located in the slot around the chain bar (11) and on the drive sprocket (20).
Turn the red chain-tensioning ring (13) clockwise ratcheting until the correct chain tension is reached. The
ratchet mechanism prevents the chain tension from loosening. If the chain-tensioning ring (13) is hard to turn,
loosen the clamping knob (14) further in anticlockwise direction.
The clamping knob (14) may also turn, when adjusting the chain-tensioning ring (13).
The saw chain (12) is correctly tensioned when it can be raised approx. 5-10 mm from the chain bar in the
centre.
This should be done by using one hand to raise the saw chain against the weight of the machine.
If the saw chain (12) is overtensioned, turn the chain-tensioning ring (13) in anticlockwise direction.
When the chain (12) is tensioned, clamp the chain bar (11) by turning the clamping knob (14) in clockwise
direction.
Do not use a tool for this. Saw chain lubrication (see figure D)
Note: The chain saw is not supplied filled with chain saw oil (delivery scope). It is essential to fill with oil before use.
Operating the chain saw without chain oil or when the oil level is below the minimum mark will result in damage to the
chain saw.
Saw chain life and cutting capacity depend on optimum lubrication. Therefore, the chain is automatically lubricated
with chain oil during operation via the oil outlet (21).
