mower to its proper cutting position and commence cutting.

Proceed down the cutting area as shown in Fig. G (a), 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 G, always working away from the cable. Do not adopt the method as shown in Fig. G (b), working towards the cable, as this is dangerous practice.

Your mower will continue to operate whilst you are depressing the switch lever. To 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: To obtain the best results cut your lawn or grass area regularly and do not cut when the grass is wet.

If, when grasscutting, 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.

Turn your mower over on its side so that

the underside of the cutter deck 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. Turn 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.

Handy hints

On long grass, above 10cm (4 inches), use two cuts to get a close finish. We recommend that the first cut should be taken with the blade set at maximum height of cut and the second taken with it set at medium or close. This will prove to be easier and give a better overall finish to

your lawn.

Care and maintenance

The advice given in this section covers the general care and maintenance of the main body of your mower. Advice relating to the blades is given in “Maintenance of blades”.

Warning! Do not use a cable which shows

!signs of damage. Fit a new cable completely - do not make any permanent or temporary repairs.

Always keep your mower clean and free from grass cuttings, especially the underside of the cutter deck and the air vents.

Check all electrical cables at regular intervals, looking for signs of wear, abrasion or other damage.

At the end of each cutting session we recommend that the build up of grass on the underside of the cutter cover is removed using a blunt scraper.

Clean all plastic components with a damp cloth.

Caution: Do not use solvents or cleaning fluids as these may damage the plastic components of your mower.
