ENGLISH

Check the correct tension has been set by lightly pulling

on the saw chain (14). The tension is correct when the saw

chain snaps back after being pulled 3 mm away from the

guide bar. There should be no “sag” between the chain guide

bar (3) and the saw chain (14) on the underside.

Note: Do not over tension the saw chain as this will lead to

excessive wear and reduce the life of the bar and saw chain.

It will also lead to reduced product performance.

Note: With first use and when the saw chain is new, check

tension frequently as a new saw chain stretches slightly.

Replacing the saw chain and chain guide bar

After prolonged use the saw chain (14) and /or chain guide

bar (3) may need replacing. Ensure only Black & Decker

recommended replacements are used.

Removing the saw chain and chain guide bar (fig. C & D)

Always wear protective gloves when installing

or removing the saw chain (14). The saw chain

is sharp and can cut you when it is not running.

Warning! The chain guide bar and the saw chain may

be hot after use. Allow to cool before replacing.

X Place the tool on a firm surface.

X Rotate the two retention bolts (12) counter clockwise

with the spanner (13) provided and remove completely.

X Remove the chain access cover (11).

X Slide the latch (5) to the unlock position, open the

handles and pull back the top jaw (1).

X Pull back chain guide bar (3) and then lift the

saw chain (14) out of the groove in the guide bar.

The saw chain can then be removed from the unit.

X The chain guide bar (3) can then be angled up

and removed.

Assembling the chain guide bar and saw chain

(fig. E & F)

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.

X Ensure the operation is carried out on a firm surface.

X Slide the latch (5) to the unlock position, open the

handles and pull back the top jaw (1).

X Insert the chain guide bar (3) into the space between

the chain tensioner and align with the chain guide bar

locator, angle the chain guide bar (3) down ensuring it

is correctly located.

X Place the saw chain (14) around the front of the chain

guide bar (3).

X Pull the chain guide bar (3) and the saw chain (14) back,

engaging it in the groove in the chain guide bar (3) and

then over the sprocket (16) positioning teeth in the

correct position on the sprocket.

X Replace the chain access cover (11) and the two

retention bolts (12) tightening securely.

X Ensure the saw chain (14) is fitted correctly with

reference to the markings on the tool.

Oiling (fig. G)

X Before first use and every ten minutes of use you must

oil the product with the correct chain oil. (Cat No A6027)

Open the oiling cover (4) and insert the bottle into the

oil filling hole (15), apply pressure to the bottle once to

dispense oil.

X This should be adequate for about 10 minutes of cutting

depending upon cutting speed and type of wood.

The hole feeds the oil through to the saw chain on to the chain

guide bar (3) and an excessive amount of oil applied to the unit

could mean the oil drips from the unit around the jaw area.

This is normal and is nothing to be concerned about.

Use

Charging the battery (fig. H)

The battery (6) needs to be charged before first use and

whenever it fails to produce sufficient power on jobs that

were easily done before. When charging the battery (6) for

the first time, or after prolonged storage, it will only accept

an 80% charge.

After several charge and discharge cycles, the battery (6)

will attain full capacity. The battery (6) may become warm

while charging; this is normal and does not indicate

a problem.

Warning! Do not charge the battery at ambient temperatures

below 4 °C or above 40 °C. Recommended charging

temperature is approximately 24 °C.

Charger (fig. H)

X To charge the battery (6), remove it from the tool and

slide the charger receptacle (10) onto the battery (6).

X Plug in the charger (9).

The battery (6) will be fully charged in approximately eight

hours. It can be removed at any time or left in the connected

charger indefinitely.

Preparation

X Carry out regular cleaning of the unit as described in the

maintenance section and in particular cleaning inside

the chain access cover (11).
