Black & Decker’ s policy is one of continuous improvement to our products and, as such, we reserve the right to change product specifications without prior notice.

Double insulation

Y our mower is double insulated. This means that all external metal parts are electrically isolated from the power supply . This is achieved by placing an extra insulation barrier between the electrical and mechanical parts. Double insulation means greater electrical safety and obviates the necessity of having your mower earthed.

Electrical safety (UK only)

Y our mower should always be switched off at the mains before disconnecting any plug

and socket connector or extension cables.

Fuse replacement

If your mower is supplied with cable fitted with a non-re-wireable plug:

• The plug is fitted with a 13 amp fuse

which is the recommended fuse for your mower .

• Only use replacement fuses which are

approved to BS1362.

• When changing the fuse in your plug,

always ensure the fuse cover is refitted. If the fuse cover is missing or damaged do not use the plug.

Note: Fuses do not give personal protection against electric shock.

Plug replacement

• Disconnect the plug from the supply .

• Cut off the plug and dispose of

immediately . Insertion of a detatched plug into a 13 amp socket outlet may result in electric shock.

• Only fit BS1363A approved plugs fitted

with the correctly rated fuse.

• The cable wire colours, or a letter , will be

marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for “Live” (L) and blue is for “Neutral” (N).

• Before replacing the top cover of the

mains plug ensure that the cable clamp is holding the outer sheath on the cable firmly and that the two leads are correctly fixed at the terminal screws.

Fit a BS1363A approved resilient plug

Connect blue to N (neutral)

Make sure that the outer sheath of the cable is held firmly by the clamp

Warning! Never connect live or neutral wires to the earth pin marked “E” or .

Note: Do not wire an extension cable directly into your mower yourself. Instead, take your mower to your nearest Black & Decker service agent.

Increased safety can be obtained by having a qualified electrician install a high sensitivity (30mA) circuit breaker in the house wiring. If you do not have such a circuit breaker installed, or you do not wish to have one installed, then we strongly recommend that the electrical power to your mower be supplied through a high sensitivity (30mA) residual current device (RCD). The RCD is designed to provide a high degree of personal protection against harmful electric current should fault conditions occur .

Warning! The use of an RCD or other circuit breaker unit does not release the operator of your mower from the safety instructions and safe working practices given in this manual.

Fit the recommended

fuse approved

to BS1362

Connect brown

to L (live)

230 volts AC only

Never use a light

How to use your mower (Fig. E & F)

Observe all of the relevant warnings when using your mower .

• Push the loop of cable through the slot

from the opposite side of the restraint hook (Fig. E1), position the loop over the hook and pull the cable back through the slot. Y our cable will now be restrained.

We recommend the directional method of operation to obtain the maximum cutting performance from your mower and to reduce the risk of the trailing the extension lead from entering the cutting path.

• Place the bulk of the supply cable on

the lawn close to the starting point (see Fig. F2a, position 1).

• Hold the handle assembly with both

hands.

Warning! Do not attempt to operate your mower with one hand - you must guide it with both hands.

• Tilt the handle downwards to slightly raise

the front of your mower and to reduce the risk of lawn damage whilst starting, depress the safety lock-off button (12) on the switchbox (10) and whilst still depressed pull the switch lever (11) towards you. Y our mower will start and you can now allow the lock-off button to be released and lower your mower to its proper cutting position, and commence cutting.

• Proceed down the cutting area as shown

in Fig. F2a, working from position 1 towards position 2 and, on reaching position 2, turn to the right and proceed towards position 3. Continue to the end of the cutting area, turn to the left and proceed towards position 4. Continue in the same manner as shown in Fig. F2a, always working away from the cable. Do not adopt the method as shown in Fig. F2b, working towards the cable, as this is dangerous practice.

Y our mower will continue to operate whilst you are pulling the switch lever . T o stop your mower release the switch lever .

When you have finished using your mower we recommend that you clean all debris from it before putting it away . Refer to the ‘Care and maintenance’ section.

Note: T o obtain the best results cut your lawn or grass area regularly and do not cut when the grass is wet.

If, when grass cutting, loose grass is seen to be scattering from beneath your mower , the grassbox is probably full and should be emptied.

Blade maintenance

The steel blade is designed to give a fine finish in long or tough grass. The blade will continue to cut even when it has become blunt or burred. There is no need for it to be razor sharp.

If, however , because of damage or wear the cutting performance deteriorates, then your mower may require a new blade, or at least the existing blade to be sharpened.

We recommend that the steel blade is sharpened or a new blade fitted at the beginning of each season.

Replacement blades are available from Black & Decker service agents.

Warning! When fitting a new blade use only the Black & Decker replacement part specified for your mower - do not attempt to fit any other blade.

Fitting a new blade (Fig. G)

Observe all the relevant warnings before changing the blade.

Warning! Disconnect your mower from the

electrical supply before changing the blade.

• T urn your mower over on its side so that

the underside of the mower body (1) is exposed.

• Using a cloth placed over the blade or

heavy duty gloves to protect your hands, grip the blade and, using the spanner provided, loosen and remove the nut (16) from the motor spindle. T urn the nut in an anti-clockwise direction to loosen it.

• The blade can now be replaced and the

washer and nut reassembled.

Note: Do not remove the impeller (17) for any reason.

Note: Some mowers are fitted with a clutch washer , between the blade nut and the blade, which must be reassembled at all times.
