MULCHING MOWING TIPS

While mulching, your new mower is designed to cut the grass clippings into small pieces and distribute them back into the lawn. Under normal conditions, the mulched grass  will biodegrade quickly and deliver 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 the runtime. The best time to mow the 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 the best mulching performance, set the cutting height to remove about one third of the grass blade length, ideally no more than 1-1/2’’ (40mm) at one time. If the lawn is overgrown, it may be necessary to increase the cutting 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 the best performance, keep the mower housing free of built-up grass. From time to time turn off mower and wait for the blades to come to a complete stop. Then turn mower on its side. Using an object such as a stick, wipe out any accumulation of grass around the blade area. Be careful of the sharp edges of the blade. Ensure to clean the blade area often when cutting wet or new grass and every time after the machine is used.

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. 6) Do not mow on a slope that has an angle of greater than 15°.

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 Height| Recommend lot size
(maximum)
---|---
Cutting off 3-1/8’’ (8cm) to
2-3/8’’ (6cm)| With 420V / 5.0Ah batteries
up to 1076 sq.ft (1000 m2)

• Used with 4 fully charged battery packs. If batteries of differing amp hours are used together, the product will operate to the lowest common denominator.

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.
2. For best performance, please ensure use 4 fully charged battery packs at the same time 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.

STORAGE (SEE FIG. O1, O2)

Stop the mower, and always remove the batteries. 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, Press and hold Quick-release button, and fold the Handle bar.

MAINTENANCE

WARNING: Stop the mower, remove the batteries 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 BATTERIES ARE 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. P)

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 . Remove the key and batteries.
2. Place the mower in stand up storage mode.
   BLADE BALANCING (See Fig. Q)

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

BLADE MAINTENANCE (See Fig. R1, R2)
Replace yourMower 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. Make sure batteries are not installed. Wedge a block of wood between the blade and the mower deck to prevent the blade from turningand 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.

For Battery tools
The ambient temperature range for the use and storage of tool and battery is 0°C-45°C (32°F-113°F). The recommended ambient temperature range for the charging system during charging is 0°C-40°C (32°F-104°F).
