OPERATION  
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 power key and battery. 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. For a healthy lawn, always cut off one-third or less of the total length of the grass.  
3. When cutting heavy grass, reduce walking speed to allow for more effective cutting and a proper  
discharge of the clippings.  
4. Do not cut wet grass. It will stick to the underside of the deck and prevent proper mulching of grass  
clippings.  
5. New or thick grass may require a narrower cut.  
6. Clean the underside of the mower deck after each use to remove grass clippings, leaves, dirt, and  
any other accumulated debris.  
7. 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. 15).  
Fig. 15  
24  
OPERATION  
MOWING ON A SLOPE (Fig. 16)  
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.  
Fig. 16  
AFTER USE  
1. Switch the product off, remove the battery pack and let it cool down.  
2. Check, clean and store the product as described below.

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 sufficient. However, if your lawn has sandy soil, more frequent sharpening  
may be required.  
Following the instructions in the Replacing Mower Blade section (Page 27), remove the mower  
blade. DO NOT attempt to sharpen the blade while it is attached to the mower.  
Using a fine-tooth file or sharpening stone, sharpen cutting edges on both ends of the blade,  
removing equal amounts of material from both ends (Fig. 19).  
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. 20)  
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.
