NOTE: Read instruction handbook before operation this machine.

ASSEMBLY & OPERATION

BATTERY STATUS (See Fig. J)

• Before starting or after use, press the button beside the power indicator light 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.

• For the machine with 2 battery packs with different power, the power indicator light displays the battery condition with the lower one of the two batteries.

Battery power indicator status	Battery condition
Five green lights ( ) are illuminated	The two batteries are in a 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.	The battery level of at least one battery pack is very low. Please check and charge the battery pack.
No light is illuminated.	At least one battery is not fully installed or battery may be defective.
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.

MULCHING MOWING TIPS

When using the mulching plug, your new mower is designed to cut the grass clippings into small pieces and distribute them back into the lawn, using mulching fins located inside the mower deck.

Under normal conditions, the mulched grass will biodegrade quickly to provide nutrients to the lawn. Please review the following recommendations for optimum mulching performance,

1. Avoid mowing when the grass is wet from rain or dew. Wet grass may form clumps which interfere with the mulching action and reduce runtime. The best time to mow grass is in the late afternoon when the grass is dry and the newly cut area will not be exposed to direct sunlight.
2. For best mulching performance, set the cutting height to remove about one third of the grass blade length, ideally no more than 1.5” inches at one time. If the lawn is overgrown, it may be necessary to increase the cut height to reduce the pushing effort and prevent overloading the motor. For extremely heavy mulching, it is advisable to first cut at a high cut height setting, and then re-cut to the final cut height. Otherwise, make narrower cuts and mow slowly.
3. For best performance, keep the mower housing free of built-up grass. From time to time turn off mower and wait for the blade to come to a complete stop. Then unplug the Safety Key(6) and turn mower on its side. Using an object such as a stick, wipe out any accumulation of grass in the blade area. Be careful of the sharp edges of the blade. Clean often in wet, new grass, and always after every use.
4. Certain types of grass or grass conditions may require that an area be mulched a second time to fully disperse the grass throughout the lawn. If cutting a second time, it is advisable to cut perpendicular (across) the first cut pattern. DO NOT CHANGE CUT PATTERN IN ANY WAY THAT WOULD CAUSE MOWING DOWN A HILL.
5. Change your cutting pattern from week to week. This will help prevent matting and graining of the lawn.

CUTTING AREA

The cutting area can be affected by many factors including: cutting height, operation practices (ex: starting/ stopping), lawn moisture levels, grass length and thickness.

It is ideal for mowing ¼ acre to ½ acre lot sizes

TIPS:

1. Mowing the lawn frequently and reducing the amount of starting/stopping procedures will help conserve battery runtime. It is recommended to always use the same two batteries during operation with fully charged levels.
2. For the best cutting performance, it is recommended to only mow up to 1/3 or less of the current grass height at a time. Mow at a slower pace when cutting long/ thick grass to allow the mower to properly discharge the clippings.

MAINTENANCE

WARNING: Stop the mower and remove the safety key before removing the grass collection 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. A DULL BLADE DOES NOT CUT GRASS CLEANLY OR MULCH PROPERLY. 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 (See Fig. N)

1. Make sure blade remains balanced.
2. Sharpen blade at the original cutting angle.
3. Sharpen cutting edges on both ends of blade to keep it balanced, 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

BLADE BALANCING (See Fig. O)

Check balance of blade by placing center hole in blade O-1 over a nail or screwdriver shank O-2, clamped horizontally in a vise O-3. If either end of the blade rotates downward, file that end. Blade is properly balanced when neither end drops.

BLADE MAINTENANCE (See Fig. P1, P2)

Replace your metal Blade after 50 hours mowing or 2 years, which ever 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 and unscrew the Blade Bolt counter-clockwise using a spanner wrench, and then remove the Blade.

To re-assemble, position the Blade with the cutting edges towards the ground. Then securely tighten the Blade Bolt.

STORAGE (SEE FIG. M1, M2)

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 knobs, and rotate or fold the Upper Handle.
