See Fig. A1, A2, A3, A4, A5 Assembling grass collection bag See Fig. B1, B2, B3, B4 Fitting grass collection bag to the lawn mower NOTE: Depress the grass collection bag slightly to ensure that it is completely installed. See Fig. C1, C2 Checking the battery charge condition NOTE: Fig. D1 only applies for the battery pack with battery indicator light. See Fig. D1 Charging the battery pack NOTE: The batteries are shipped uncharged. Each battery must be fully charged before the first mow. Always fully charge the two batteries at same time. More details can be found in charger’s manual. See Fig. D2, D3 Fitting/removing battery NOTE: This machine will only run when 2 batteries are installed. Please always use two batteries with the same capacity and fully charge the two batteries. When you use two batteries with different power, the machine will only run to the lower common denominator. See Fig. E OPERATION Battery power indicator on the machine See details in BATTERY STATUS part IMPORTANT When only one light is illuminated, at least one battery is depleted and needs to be charged, even though the mower may still be capable of cutting grass. Continuing to operate your lawnmower with the battery in this discharged condition may reduce the life and performance of your battery. When no light is illuminated, at least one battery is not fully installed or battery may be defective, please double check the batteries are fully seated into position. See Fig. F Starting & stopping See Fig. G1, G2 Adjusting the Cutting Height WARNING! Stop, release switch lever and wait until the motor stops before adjusting height. The blades continue to rotate after the machine is switched off, a rotating blade can cause injury. Do not touch rotating blades.

is illuminated. At least one battery is almost depleted and needs to be charged. No light is illuminated. At least one battery is not fully installed or battery may be defective.16 Cordless Lawn Mower EN Only one light is flashing twice per cycle. At least one battery is over discharged (please refer to the battery charge condition), please recharge the two batteries at once before use again or storage. Only one light is flashing three times per cycle. At least one battery is hot, wait for them cool down before start again. Only one light is flashing four times per cycle. The machine is over load. Raise the cutting height or push slowly. MOWING TIPS

1. 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.

2. Release switch lever to turn mower “OFF” when

crossing any graveled area (stones can be thrown by the blade).

3. Set mower at highest cutting height when

mowing in rough ground or in tall weeds. Removing too much grass at one time can cause circuit breaker to trip, which stops mower.

4. If a grass bag is used during the fast growing

season, the grass may tend to clog up at the discharge opening. Release switch lever to turn 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.

5. If mower should start to vibrate abnormally,

release switch lever to turn mower “OFF” and remove safety key. Check immediately for cause. Vibration is a warning of trouble. Do not operate mower until a service check has been made.

6. ALWAYS RELEASE SWITCH LEVER TO TURN

MOWER “OFF” AND REMOVE 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 table below gives the relationship between cutting conditions and cutting area. Cutting conditions Cutting area (maximum) Grass conditions Cutting height

battery Very thin, dry grass cut 7cm to 5cm 230m

Thin, dry grass cut 7cm to 3cm 120m

• 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

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.17

Cordless Lawn Mower EN

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: 1. Be sure the mower is turned off and remove the key.

1. Be sure the switch lever is released, the blade

has stopped and the safety key removed before removing the blade.

2. Remove blade from mower. See instructions for

removing and attaching blade.

3. Secure blade L-1 in a vise L-2.

4. Wear safety glasses and be careful not to cut

5. Carefully file the cutting edges of the blade with a

fine tooth file L-3 or sharpening stone.

7. Replace blade on mower and tighten securely.

Refer to instructions below. BLADE BALANCING (SEE Fig. M) Check balance of blade by placing center hole in blade M-1 over a nail or screwdriver shank M-2, clamped horizontally in a vise M-3. If either end of the blade rotates downward, file that end. Blade is properly balanced when neither end drops. BLADE MAINTENANCE (See Fig. N1, N2) Renew your metal blade after 50 hours 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 (18) and unscrew the blade bolt (17) counter-clockwise using a spanner wrench, and then remove blade. To re-assemble, position the blade (18) with the cutting edges towards the ground. Then securely tighten the blade bolt (17). STORAGE (See Fig. K1, K2) 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 handle knob, and fold the upper handle as shown in Fig. K1 & K2. ENVIRONMENTAL PROTECTION Waste electrical products must not be disposed of with household waste.
