Vibration
The declared vibration emission values stated in the technical data and the declaration of conformity have been measured in accordance with a standard test method provided by EN50636 and may be used for comparing one tool with another. The declared vibration emission value may also be used in a preliminary assessment of exposure.
Warning! The vibration emission value during the actual use of the power tool can differ from the declared value depending on the ways in which the tool is used.
The vibration level may increase above the level stated.
When assessing vibration exposure to determine safety measures required by 2002/44/EC to protect persons regularly using power tools in employment, an estimation of vibration exposure should consider, the actual conditions of use and the way the tool is used, including taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time.
Do not operate the tool if the vibration registers as abnormal.

Safety of others

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.
Unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.
Children must be supervised to ensure that they do not play with the appliance.
After striking a foreign object. Inspect the appliance for damage and make repairs as necessary.

Residual risks

Additional residual risks may arise when using the tool which may not be included in the enclosed safety warnings. These risks can arise from misuse, prolonged use, etc. Even with the application of the relevant safety regulations and the implementation of safety devices, certain residual risks can not be avoided. These include:

Injuries are caused by touching any moving parts.
Injuries are caused by touching any hot parts.
Injuries are caused when changing any parts or accessories.
Injuries caused by prolonged use of the appliance. When using any appliance for prolonged periods ensure you take regular breaks.
Impairment of hearing.
Health hazards caused by breathing dust developed when using your tool (for example:- working with wood, especially oak, beech, and MDF.)
If operating the mower in a damp location is unavoidable, use a residual current device (RCD) with a tripping current of not more than 30 mA.
The use of an RCD reduces the risk of electric shock.
Never pick up or carry an appliance while the motor is running.

Align the assembled sides onto the bottom (13d) of the grass collection box. Ensure that the 4 guides are aligned (fig. E)
Push the 2 parts together. Apply even force around all edges of the grass collection box securing the clips into position uniformly. Check that each clip is fastened together securely.

Fitting the lower handle (fig. F)

Insert the ends of the lower handles (7) into the corresponding holes in the mower.
Press the handle down as far as it will go.
Secure the handle using the screws.

Assembling the upper handle (fig. G)

Fit the upper handle part to the lower handle using the handle knobs (6), washers, and screws as shown.
Securing the motor cable (fig. H)
The motor cable has to be fixed using the cable restraint.
Snap a restraint clip (14) around the cable and lower handle about 150mm below the handle knob (6).

Fitting the grass collection box (fig. I)

Lift the flap (9) and place the grass collection box (13) ensuring the recesses (13f) fit over the lugs (13g).

Proper Hand Position (Fig. J)
Warning! To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.
Warning!: To reduce the risk of serious personal injury,

ALWAYS hold securely in anticipation of a sudden reaction.
Proper hand position requires one hand on each of the comfort grip handles (2).

Adjusting the height of the cut (fig. K)
The height of the cut is adjusted by the central height adjust mechanism, there are 6 positions to choose from.

Pull the height adjustment lever (12) away from the body of the unit.
Move the lever towards the rear of the appliance to lower the height of the cut.
Move the lever towards the front of the appliance to raise the height of the cut.

Ensure that the cable management system (BEMW471BH, BEMW481BH units only) can slide freely from one side to the other.
Place the bulk of the main cable on the lawn, close to the starting point (position 1 in fig. O1).
Switch the appliance on as described above.
Proceed as shown in fig. O1
Move from position 1 to position 2.
Turn right and proceed towards position 3. The cable management system will slide from one side to the other, ensuring the extension cord is kept away from the cutting blade.
Turn left and move towards position 4.
Repeat the above procedure as required.
Warning! Do not work toward the cable as shown in fig. O2.

Up to edge cutting (fig. P, Q)
Up to edge cutting allows you to cut grass right up to the edge of a wall or fence (fig P).
Up to edge cutting allows you to accurately cut grass right up to the edge of your lawn (fig Q).

With the lawnmower parallel with the edge of your lawn, push the lawnmower along the edge of the lawn. Ensure that the edge of mower is slightly over the edge of your lawn (fig.Q).

Cable tidy (fig. R)

Cable tidy, stores cable when not in use. Only available on BEMW471BH & BEMW481BH GB units.

Removing Blade (Fig. S, T)
Note: BEMW461BH, BEMW471BH & BEMW481BH all use new winged blades which improves collection vs previous range of mowers. Blade accessories Cat # 34cm A6320 38cm A6321 42cm A6322.
Warning! Ensure the blade has completely stopped and disconnected the mower from the power source.

Cut a piece of 2×4 wood (16) 305mm to keep the blade from turning while removing the flange nut.
Turn the appliance onto its side. Wear gloves and proper eye protection. Be careful of the sharp edges of the blade.
Position a piece of wood (16) to keep the blade from turning as shown in Fig. S.
Use a 14mm wrench (18) to loosen and remove the blade bolt by turning counterclockwise.
Pull off the blade (17), and blade insulator (19), as shown in Fig. T. Examine all pieces for damage and replace if necessary.

Installing Blade (Fig. U)

Place the blade insulator (19) then the blade (17) onto the bolt shaft with the lettering on the blade facing out, and place the blade bolt (20) onto the bolt shaft.
Tighten the blade bolt as firmly as possible by hand.
Position a piece of wood (16) to keep the blade from turning as shown in Fig. U.
Use a 14mm wrench to securely tighten the blade bolt by turning the wrench clockwise.

Blade sharpening
Keep the blade sharp for the best mower performance. A dull blade does not cut grass cleanly. Use proper eye protection while removing, sharpening, and installing the blade. Sharpening the blade twice during a mowing season is usually sufficient under normal circumstances.
Sand causes the blade to dull quickly. If your lawn has sandy soil, more frequent sharpening may be required.
Note: Replace bent or damaged blade immediately.

Troubleshooting

If your appliance seems not to operate properly, follow the instructions below. If this does not solve the problem, please
contact your local BLACK+DECKER repair agent.
Warning! Before proceeding, release the bail bar to turn mower off and wait for the blade to stop.
