Operate the Lawn Mower

Operation on a Slope

Slopes are a major factor in slip-and-fall accidents.

WARNING: Always ensure good footing on slopes. Exercise extra caution. If uneasy, do not mow the slope.

• DO: Mow across the face of slopes, never up and down. Exercise extreme caution when changing direction. Watch for holes, ruts, rocks, hidden objects, or bumps. Tall grass can hide obstacles.
• DO NOT: Mow near drop-offs or embankments. Do not mow slopes greater than 15 degrees. Do not mow on wet grass.

Mower Overload Protection

To prevent overload, do not cut too much grass at once. Slow down your pace or raise the cutting height. The mower has built-in overload circuit protection. If overloaded, the motor will stop. Switch off the mower, remove the battery, check for grass buildup under the deck, clear if necessary, and restart.

Battery High Temperature Protection

The battery pack generates heat during operation. If the battery temperature exceeds 158°F, the protection circuit will turn off the mower. Release the bail handle, wait for the battery to cool, then restart.

Function of Grass Bag Full Indicator

• If the grass bag is empty, the indicator is open (See Figure 22).
• If the grass bag is full, the indicator is closed (See Figure 22).

Emptying the Grass Bag

When the grass bag full indicator starts to close, it's time to empty the bag.

NOTE: Switch OFF the power and wait for the blade to stop before removing the bag.

1. Lift the ejector flap with one hand and grab the carry handle with the other. The flap automatically closes off the rear chute opening when the bag is removed.
2. Empty the grass debris from the bag and refit it.

NOTE: If grass residue is caught in the discharge chute, clean it with a brush. Do not use hands or feet. Use suitable tools like a brush or broom. Ensure the discharge opening and chute are clear of blockages for proper collection.

Maintenance and Storage

WARNING: Before any maintenance or cleaning, ensure the battery pack/safety key is removed and the blade has stopped completely and the tool has cooled down.

Cleaning

• Use a soft brush to remove dust and debris. Wear safety glasses.
• Wipe the product enclosure with a slightly damp cloth. Do not spray with water, as it may damage the switch unit and electric motor.

Maintenance

NOTE: Always wear gardening gloves when handling or working near sharp blades.

1. Keep all nuts, bolts, and screws tight for safe working condition.
2. Check the grass bag frequently for wear or deterioration.
3. Examine the machine and replace worn or damaged parts for safety.

Removing/Installing the Blade (See Figures 23 & 24)

1. Use a wrench of the correct size on the blade bolt nut.
2. Hold the blade fixed with heavy gloves and turn the wrench counter-clockwise to remove the bolt.
3. Fit the replacement blade correctly with the marking facing up, align pegs, fit the bolt, and retighten securely to 36-43 Ft. Lb.

WARNING! Replace or re-sharpen the mowing blade at the end of the mowing season. Always have the blade re-sharpened or replaced by a customer service center for balancing. Unbalanced blades can cause violent vibration and risk of accident!

Battery Maintenance

• Protect the battery against moisture and water.
• Store the battery in a temperature range of 32°F to 113°F. Do not leave it in direct sunlight.
• Clean the battery occasionally with a soft, clean, dry brush.
