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 AREA

Very thin,
dry grass| cut 8cm to 6cm| 280m2| 460m2| 230m2
Thin, dry grass| cut 8cm to 4cm| 140m2| 230m2| 115m2

• Used with two fully charged battery packs.
  TIPS:

  1. It is recommended to mow your lawn more frequently, walk at a 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 the same time.
  2. For best performance, please ensure to 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.

BATTERY STATUS (See Fig. F)
Before starting or after use, press the button “POWER TEST” on the machine to check the battery capacity. During operation, the battery capacity will be indicated automatically by the battery power indicator. The indicator constantly senses and displays the battery condition as follows:

highly charged condition.
Two, three or four green lights are illuminated.| The two batteries have a remaining charge. The more lights are illuminated the more battery capacity.
Only one green light is illuminated.| At least one battery is depleted and needs to be charged.
No light is illuminated. ill| At least one battery is not fully installed or the battery is defective.
Only one light Clashing twice per cycle.| At least one battery is over- discharged, 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 to cool down before starting again.
Only one light is Bashing tour times per cycle.| The machine is overloaded. Raise the cutting height or push slowly.

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.

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 the switch lever to turn the mower “OFF” when crossing any graveled area (stones can be thrown by the blade).
3. 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.
4. If a grass bag is used during the fast-growing season, the grass may tend to clog up at the discharge opening. Release the switch lever 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.
5. If the mower should start to vibrate abnormally, release the switch lever 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.
6. ALWAYS RELEASE THE SWITCH LEVER TO TURN THE MOWER “OFF” AND REMOVE THE SAFETY KEY WHEN LEAVING IT UNATTENDED EVEN FOR A SHORT PERIOD OF TIME.

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 loose, dislodged, or damaged blades, lose fittings, and worn or damaged components. Check that the covers and guards are all undamaged and are correctly attached to the mower. Carry out any necessary maintenance or repairs before the 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 BLADES. ENSURE THAT THE 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 the blade remains balanced.
2. Sharpen the blade at the original cutting angle.
3.  Sharpen cutting edges on both ends of the blade, removing equal amounts of material from both ends.

Note:

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

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

1. Be sure the switch lever is released, the blade has stopped and the safety key is removed before removing the blade.
2. Remove blade from mower. See instructions for removing and attaching the blade.
3. Secure blade M-1 in a vise M-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 M-3 or sharpening stone.
6. Check the balance of the blade. See instructions for blade balancing.
7. Replace blade on mower and tighten securely. Refer to the instructions below.

BLADE BALANCING (SEE Fig. N)
Check the balance of the blade by placing a center hole in the blade N-1 over a nail or screwdriver shank N-2, clamped horizontally in a vise N-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. O1, O2)
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 (16) and unscrew the blade bolt (15) counter-clockwise using a  spanner wrench, and then remove the blade. To re-assemble, position the blade (16) with the cutting edges towards the ground. Then securely tighten the blade bolt (15).

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 them 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. L1 & L2.
