Bosch EasyChain 18V-15-7 Original Instructions Manual page 19

That the declared vibration total value(s) and the declared
noise emission value(s) have been measured in accordance
with a standard test method and may be used for comparing
one machine with another.
That the declared vibration total value(s) and the declared
noise emission value(s) may also be used in a preliminary as-
sessment of exposure.
That the vibration and noise emissions during actual use of
the machine can differ from the declared total value depend-
ing on the ways in which the machine is used; and of the
need to identify safety measures to protect the operator that
are based on an estimation of exposure in the actual condi-
tions of use (taking account of all parts of the operating cycle
such as the times when the machine is switched off and
when it is running idle in addition to the trigger time).
Assembly
Inserting/removing the battery (see figure D)
Note: Using unsuitable batteries can lead to malfunctions or
damage the machine.
Insert the charged battery (16). Make sure that the battery
is fully fitted.
To remove the battery (16) from the machine, press the bat-
tery unlocking button (25) and pull the battery out.
Charging the Battery
Observe the correct mains voltage! The voltage of the
u
power supply must correspond with the data given on
the nameplate of the battery charger. Battery char-
gers marked with 230 V can also be operated with
220 V.
The battery is equipped with temperature monitoring that al-
lows charging only in the temperature range between 0 °C
and 35 °C. In this manner, a high battery service life is
achieved.
Note: The battery is supplied partially charged. To ensure
full battery capacity, completely charge the battery in the
battery charger before using for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the battery.
The "Electronic Cell Protection (ECP)" protects the lithium-
ion battery against deep discharging. When the battery is
empty, the product is switched off by means of a protective
circuit: The product no longer operates.
Do not continue to press the On/Off switch after an auto-
matic shut-off of the product. The battery could become
damaged.
Observe the notes for disposal of the battery.
Charging Procedure
The charging procedure starts as soon as the mains plug of
the charger is plugged into a socket outlet and the battery
(16) is inserted in to the charger
Bosch Power Tools
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery
is charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.
Mounting and Tensioning the Saw Chain (see
figures B1 – B7)
Do not use any tools for assembly.
u
Check the chain tension regularly during use. Using
u
the pruner saw with a misaligned or improperly tensioned
chain may result in chain breakage, kickback, and/or in-
jury.
Upon initial operation, new chains can lengthen con-
u
siderably.
Avoid tensioning the chain if it is hot, as this will cause
u
the chain to become overtensioned and fit too tightly
against the chain bar when it cools down.
Use only chains with a drive link thickness of 1.1 mm.
u
– Place the pruner saw on any suitable flat surface.
– Make sure that the tensioning wheel (2) has been turned
fully in anticlockwise direction.
– Slot in the saw chain (14) in the gap of the chain bar
(15). Ensure the saw chain is in the correct running direc-
tion by comparing the saw chain with the symbol for rota-
tion and cutting direction (19).
– Place the chain bar (15) on the fastening bolt (21) and
place the chain links around the drive sprocket (24).
– Check if all parts are positioned properly and hold the
chain bar and the chain in this position. Use the magnet
(20) for added support when aligning the chain bar into
position.
– Rotate the affixed tensioning wheel (2) clockwise until
the chain is partially tensioned.
– Attach the cover (11) and rotate the SDS lock (12) clock-
wise until the cover is partially secured.
– Turn the tensioning wheel (2) clockwise (+) until the cor-
rect chain tension is reached. The saw chain (14) is cor-
rectly tensioned when it can be raised approx. 2–3 mm
from the chain bar.
– Once the correct tension is reached, rotate the clamping
knob (12) clockwise until it is firmly secured and fold
down the bracket on the clamping knob (12). The chain
bar is fixed in the set position. Do not continue to turn the
tensioning wheel (2)
– If the chain is tensioned too tightly, fold up the bracket on
the clamping knob (12) and turn partly anti-clockwise.
Turn the tensioning wheel (-) and repeat the tensioning
steps.
Saw-chain Lubrication (see figure C)
The saw chain is not automatically lubricated with chain oil
during operation.
Check the saw chain before each use and apply oil manually.
