Meaning of the Indication Elements
(AL 1830 CV)
(Fast) Flashing of the Green Battery Charge Indicator
The rapid-charging procedure is indicated by
fast flashing of the green battery charge in-
dicator .
Note: The rapid-charging procedure is only possible when
the battery temperature is within the allowable charging
temperature range, see section "Technical Data".
(Slow) Flashing of the Green Battery Charge Indicator
When the charging condition of the battery is
80%, the green battery charge indicator
flashes slowly.
The battery can be removed for immediate use.
Continuous Lighting of the Green Battery Charge
Indicator
Continuous lighting of the green battery
Full
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 in-
serted 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 indic-
ates a different malfunction of the charging
procedure, see section "Troubleshooting – Causes and Cor-
rective Measures".
Charging Advice
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaning-
ful and does not indicate a technical defect of the battery
charger.
A significantly reduced working period after charging indic-
ates 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
u
completely assembled.
Always wear protective gloves when handling the
u
chain.
Chain and chain bar assembly (see figures A1–A4)
Use only chains with a drive link thickness of 1.1 mm.
u
– Unpack all parts carefully.
Bosch Power Tools
– 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 direc-
tion 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 consider-
ably.
The chain life of the saw chain mainly depends upon suffi-
cient lubrication and correct tensioning.
Avoid tensioning the chain if it is hot, as this will cause the
chain to become overtensioned 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 anticlock-
wise 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 ratchet-
ing 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-ten-
sioning ring (13) in anticlockwise direction.
– When the chain (12) is tensioned, clamp the chain bar
(11) by turning the clamping knob (14) in clockwise dir-
ection. 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. Op-
erating 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 lub-
rication. Therefore, the chain is automatically lubricated with
chain oil during operation via the oil outlet (21).
