NOISE DATA

VIBRATION INFORMATION

WARNING : The vibration emission value during actual use of the power tool can differ from the declared value depending on the ways in which the tool is used depending on the following examples and other variations on how the tool is used:

• How the tool is used and the materials being cut or drilled.
• The tool is in good condition and well maintained. Using the correct accessory for the tool and ensuring it is sharp and in good condition.
• The tightness of the grip on the handles and if any anti-vibration accessories are used.
• And the tool is being used as intended by its design and these instructions.
• This tool may cause hand-arm vibration syndrome if its use is not adequately managed

WARNING : To be accurate, an estimation of exposure level in the actual conditions of use should also take account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Helping to minimize your vibration exposure risk. ALWAYS use sharp chisels, drills, and blades. Maintain this tool in accordance with these instructions and keep well lubricated (where appropriate). If the tool is to be used regularly then invest in anti-vibration accessories. Plan your work schedule to spread any high vibration tool use across a number of days.

MOWING TIPS
NOTE: ALWAYS INSPECT THE AREA WHERE MOWER IS TO BE USED AND REMOVE ALL STONES, STICKS, WIRE, METAL, AND OTHER DEBRIS WHICH MIGHT BE THROWN BY THE ROTATING BLADE.

• Mow across the face of slopes, never up-and-down. Exercise extreme caution when changing direction on slopes. Do not mow excessively steep slopes. Always maintain good footing.
• Release the bail handles to turn the mower “OFF” when crossing any graveled area (stones can be thrown by the blade).
• Set mower at highest cutting height when mowing in the rough ground or in tall weeds. Removing too much grass at one time can cause the circuit breaker to trip, which stops the mower.
• If a grass bag is used during the fast-growing season, the grass may tend to clog up at the discharge opening. Release the bail handle to turn the mower “OFF” and remove the safety key. Remove the grass bag and shake the grass down to the back end of the bag. Also, clean out any grass or debris which may be packed around the discharge opening. Replace the grass collection bag.
• If the mower should start to vibrate abnormally, release the bail handle to turn the mower “OFF” and remove the safety key. Check immediately for cause. Vibration is a warning of trouble. Do not operate the mower until a service check has been made.
• ALWAYS RELEASE THE BAIL HANDLE TO TURN THE MOWER “OFF” AND REMOVE THE SAFETY KEY WHEN LEAVING IT UNATTENDED EVEN FOR A SHORT PERIOD OF TIME.

CUTTING AREA

The cutting area can be affected by several factors, such as cutting height, lawn humidity, grass length and density. Besides, starting and stopping the mower too many times during operation will reduce the cutting area. The below table provides the potential cutting areas based on specific cutting conditions.

Cutting off 8cm to 6cm

| With 220V / 4.0Ah batteries
up to 500m2

Used with two fully charged battery packs.

TIPS:

1. It is recommended to mow your lawn more frequently, walk at normal pace, and not to start/stop the mower too often during operation. Please always use the same two batteries and charge the two batteries at same time.
2. For best performance, please ensure use a fully charged battery pack and always cut off 1/3 or less of the grass height.
3. Walk slowly when cutting long grass, so as to have more effective cutting and properly discharge the clippings.
4. Avoid cutting wet grass, otherwise it will stick to the underside of the deck and the clippings cannot be collected or discharged properly.
5. A higher cutting height shall be applied to new or thick grass and it will extend the battery duration.

MAINTENANCE

WARNING : Stop the mower and remove the safety key before removing the grass bag.
NOTE : To ensure long and reliable service, perform the following maintenance procedures regularly. Check for obvious defects such as a loose, dislodged or a damaged blade, loose fittings, and worn or damaged components. Check that the covers and guards are all undamaged and are correctly attached to mower. Carry out any necessary maintenance or repairs before operating mower. If the mower should happen to fail despite regular maintenance, please call our customer helpline for advice.

BLADE SHARPENING

KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. WEAR PROPER EYE PROTECTION WHILE REMOVING, SHARPENING, AND INSTALLING BLADE. ENSURE THAT SAFETY KEY IS REMOVED.
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. REPLACE BENT OR DAMAGED BLADE IMMEDIATELY.

WHEN SHARPENING THE BLADE:

1. Make sure blade remains balanced.
2. Sharpen blade at the original cutting angle.
3. Sharpen cutting edges on both ends of blade, removing equal amounts of material from both ends.

NOTE:

• Be sure the mower is turned off and remove the key.
• Place the mower in stand-up storage mode.

TO SHARPEN BLADE IN A VISE (SEE Fig. M1)

1. Be sure the bail handle is released, the blade has stopped and the safety key is removed before removing the blade.
2. Remove the blade from the mower. See instructions for removing and attaching the blade.
3.  Secure blade M1-1 in a vise M1-2.
4. Wear safety glasses and be careful not to cut yourself.
5. Carefully file the cutting edges of the blade with a fine tooth file M1-3 or sharpening stone.
6. Check the balance of blade. See instructions for blade balancing.
7. Replace the blade on the mower and tighten securely. Refer to the instructions below.

BLADE BALANCING (SEE Fig.M2)

Check the balance of the blade by placing the center hole in blade M2-1 over a nail or screwdriver shank M2-2, clamped horizontally in a vise M2-3. If either end of the blade rotates downward, file that end. The blade is properly balanced when neither end drops.
BLADE MAINTENANCE (SEE FIG. N1, N2) Renew your metal blade after 50 hours of mowing or 2 years, whichever is the sooner-regardless of condition.
Follow these procedures to remove and replace the blade. You will need garden gloves (not provided) and a spanner wrench (not provided) to remove the blade. Hold the blade (19) and unscrew the blade bolt (18) counter-clockwise using a spanner wrench, and then remove the blade.
To re-assemble, position the blade (19) with the cutting edges towards the ground. Then securely tighten the blade bolt (18).

STORAGE (SEE Fig. L1, L2)

Stop the mower and always remove the safety key. Clean the exterior of the machine thoroughly using a soft brush and cloth. Do not use water, solvents or polishes. Remove all grass and debris, especially from the ventilation slots.
Turn the machine on its side and clean the blade area. If grass cuttings are compacted in the blade area, remove with a wooden or plastic implement.
Store the machine in a dry place. Do not place other objects on top of the machine.
To aid storage, release the Lock Cam Lever, and fold the upper handle as shown in Fig. L1, L2.
