Electrical safety
This tool is double insulated; therefore no earth wire
is required. Always check that the power supply
corresponds to the voltage on the rating plate.
Additional safety instructions
This appliance is not intended for use by young or infirm
persons without supervision. Children must be supervised
to ensure they do not play with the appliance.
If the supply cord is damaged, it must be replaced by the
manufacturer or an authorised Black & Decker Service
Centre in order to avoid a hazard.
Residual Risk
Despite the application of the relevant safety regulations
and the implementation of safety measures, certain residual
risks are inherent to the use of wood cutting saws and
cannot be avoided. These are:
Risk of injury arising from contact with moving parts, sharp
parts, hot parts, branches or debris falling on the operator,
bystanders or property, debris ejected by the tool.
Risk of injury arising from un-intended use, falling from a
ladder or working position in a tree, damage to the supply
cable, use of the tool in wet or hazardous locations, use of
the product by young children or infirm persons, failure to
wear suitable personal protection or suitable clothing,
breathing dust generated from cutting wood.
The above risks have been addressed by including warnings
in the safety instructions and/or markings applied to the tool.
The vibration value stated in this manual is in accordance
with the standardised test of EN60745. The operator should
not be exposed to high levels of vibration for extended
periods of time. The vibration emissions of this tool are
below 5m/s and are within the limits set by 2002/44/EC for
continuous operation in an 8 hour day. The actual operating
conditions may vary or possibly increase the vibration level
from those recorded in the standardised test.

Chain tension adjustment (fig. A)
Warning! Before chain or other adjustments, make sure that
the tool is switched off and unplugged.
Warning! Guide bar and chain may be hot after use. Allow to
cool before adjustment.
The product comes ready assembled. However we recommend
that you check the tension of the chain, and chain retention nuts
before use and if required adjust.
Checking and adjusting the chain tension (fig. A)
To tension the chain slacken the two chain cover retention
nuts (11) with the spanner (2) and the chain tensioning
device will push the chain bar out, setting the correct
tension. Retighten the two retention nuts (11) securely.
Check the correct tension has been set by lightly pulling on
the chain. The tension is correct when the chain snaps back
after being pulled 3 mm away from the guide bar. There
should be no "sag" between the guide bar and chain on the
underside.
Note: Do not over tension the chain as this will lead to
excessive wear and reduce the life of the bar and chain. It
will also lead to reduced product performance.
Note: With first use and when the chain is new, check
tension frequently as a new chain stretches slightly.
Replacing the chain and chain bar
After prolonged use the chain and /or chain bar may need
replacing. Ensure only Black & Decker recommended
replacements are used.
Removing the saw chain & chain bar (figs. A & B)
Warning! Always wear protective gloves when installing or
removing the saw chain. The saw chain is sharp and can cut you
when it is not running.
Warning! Guide bar and chain may be hot after use. Allow to
cool before replacing.
Place the tool on a firm surface.
Rotate the two retention nuts (11) counter clockwise with
spanner (2) provided and remove completely.
Remove the chain access cover (12).
Open the handles and pull back the top jaw (6).
Pull back chain bar (8) and then lift the saw chain (9) out of
the groove in the guide bar. The chain can then be removed
from the unit.
The chain bar can then be angled up and over the bolts.
Assembling the chain bar and chain (figs. C & D)
Warning! Always wear protective gloves when installing or
removing the saw chain. The saw chain is sharp and can cut you
when it is not running.
Ensure the operation is carried out on a firm surface.
Open the handles and pull back the top jaw (6).
