BATTERY CHARGING
1. Use only with 24V LawnMaster
®
battery chargers. The battery charger supplied is specically designed for
the lithium-ion batteries used in this tool.
2. Check the power voltage! Battery chargers operate on 120V.
3. The batteries are charged between 40°F (4°C) and 100°F (38°C). This ensures an optimum battery
service life.
4. Protect the batteries from heat, from continuous exposure to sun and keep away from radiation or other
heat sources. Do not leave the batteries in the mower in direct sunlight over long periods.
5. The batteries are supplied partially charged. To ensure full capacity of each battery, charge the batteries
before using the tool for the rst time. The lithium-ion batteries can be charged at any time without reducing
their service life. Interrupting the charging procedure does not affect the batteries.
LED CHARGER STATUS
1. If batteries are not inserted into the charger, continuous red LED lights indicate that the outlet plug is
plugged into an outlet socket and the battery charger is ready for operation.
2. Charging: Flashing green LEDs on the charger indicate that batteries are charging normally. The LED’s
ashing frequency is 1Hz.
3. Charged: Continuous green LEDs on the charger indicate that batteries are ready for use.
4. Technical Issue: Flashing red LED lights on the charger indicates that batteries have a charging problem
or might be defective.
a) One possible condition is the battery temperature is lower than 0°C. As soon as the permitted
temperature is reached, the battery charger will automatically switch to charging.
b) If the temperature range is correct and ashing red LED light continues, then remove and reinstall the
battery pack. If the LED status repeats a second time, try to charge another identical battery. If the battery
charges normally, dispose of the defective battery pack (see Environmental Safe Battery Disposal
section).
c) If the ashing red light continues after installing the second battery, the charger may be defective.
Replace with a new one.
5. Flashing green LED lights on the charger (the LED’s ashing frequency (2Hz) is faster than charging
normally (1Hz)), which indicates the battery temperature is higher than 50°C. As soon as the permitted
temperature is reached, the battery charger will automatically switch to charging.
6. After continuous or repeated charging cycles without interruption, the charger may warm up. This is normal
and does not indicate a technical defect of the battery charger.

GENERAL OPERATION
Check the product, its power cord and accessories for damage before each use. Before use, please
ensure all power connections are in good working order prior to installing the safety key and battery
packs. If damage is present or observed, please stop and have mower serviced before use.
Do not use the product if it is damaged or shows wear.
1. Double-check that the blade is properly installed.
2. Always hold the product by its handles. Keep the handles dry to ensure safe support.
3. Switch the equipment off immediately if someone enters the work area. Always let the equipment
come to complete stop before removing the grass collection bag.
4. Do not overwork yourself. Take regular breaks to ensure you can concentrate on the work and have
full control over the product.
MOWING TIPS
1. Make sure the lawn is clear of stones, sticks, wires, and other objects that could damage the lawn
mower blades or motor. Such objects could be accidentally thrown by the mower in any direction
and cause serious personal injury to the operator and others.
2. To reduce the chances of disconnecting the lawn mower from the extension cord, be sure to use the
cord retainer provided.
3. For a healthy plot of grass, always cut off one-third or less of the total length of the grass.
4. When cutting heavy grass, reduce walking speed to allow for more effective cutting and a proper
discharge of the clippings.
5. Do not cut wet grass. It will stick to the underside of the deck and prevent proper mulching of grass
clippings.
6. New or thick grass may require a narrower cut.
7. Clean the underside of the mower deck after each use to remove grass clippings, leaves, dirt, and
any other accumulated debris.
8. Mow in slight overlapping rows. The most effective pattern for mowing lawns is in straight lines
along one of the sides. This will keep the rows even and ensure that the lawn is cut without missing
any spots (Fig. 17).

26
OPERATION
MOWING ON A SLOPE (Fig. 18)
1. Slopes are a major factor related to slip and fall accidents that can result in severe injury. Mowing
on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. For your safety, do
not attempt to mow slopes greater than 15 degrees.
2. Mow across the face of slopes, not up and down. Exercise extreme caution when changing direction
on slopes.
3. Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass
can hide obstacles. Remove all objects such as rocks, tree limbs, etc., which could be tripped over
or thrown by the blade.
4. Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are
losing your balance, release the start/stop bale switch immediately.
5. Do not mow near drop-offs, ditches, or embankments; you could lose your footing or balance.

MAINTENANCE
SHARPENING THE BLADE
For best mowing performance, the mower blade must be kept sharp. A dull blade does not cut grass
evenly and overloads the motor. Under normal circumstances, sharpening the blade twice during the
mowing season is usually sufcient. However, if your lawn has sandy soil, more frequent sharpening
may be required.
• Following the instructions in the Replacing The Mower Blade section (Page 28), remove the mower
blade. DO NOT attempt to sharpen the blade while it is attached to the mower.
• Using a ne-tooth le or sharpening stone, sharpen cutting edges on both ends of the blade,
removing equal amounts of material from both ends (Fig. 21).
WARNING
When removing, inspect the blade carefully. If blade is bent or damaged, replace immediately with a
new blade. Failure to replace a bent or damaged blade could cause an accident resulting in possible
serious injury.
BALANCING THE BLADE (Fig. 22)
When sharpening, care should be taken to keep the blade balanced. An unbalanced blade will cause
excessive vibration when the mower is running. This vibration will eventually cause damage to the
mower, especially the motor.
To check the blade balance:
• Clamp a screwdriver horizontally in a vise as shown.
NOTE: If a vise is not available, a straight nail can also be used.
• Place the center hole of blade on the screwdriver (or nail) shank.
• If blade is balanced, it will remain in a horizontal position. If either end of the blade drops downward,
sharpen the heavy side until the blade is balanced.
