STARTING/STOPPING THE MOWER

1. To switch on, insert the safety key, press and hold the safety switch button and gently pull the start/stop bale switch (Fig. 13 &14). Once started, release the safety switch button.
2. To power off the mower, release the start/stop bale switch. Pull out the safety key if the mower is not going to be used immediately.

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).

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.

LUBRICATION

All of the bearings in this product are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further bearing lubrication is required. At the beginning and end of each mowing season:

1. Lubricate the springs on the rear discharge door with light oil.
2. Lubricate the cutting height adjustment lever and related hardware with light oil.
3. Remove the wheels and lubricate the surface of the axle bolt and the inner surface of the wheels with light oil.
4. Remove the blade and blade hub assembly and lubricate the motor shaft with light oil or engine oil. See Replacing the Cutting Blade section for instructions on removing the blade.

WARNING

Always protect hands by wearing heavy gloves and/or wrapping the cutting edges of the blade with rags and other material when performing blade maintenance. Failure to heed this warning could result in serious personal injury.

WARNING

Before performing any maintenance, make sure the mower is unplugged from the power supply and battery has been removed. Failure to heed this warning could result in serious personal injury.

REPLACING THE MOWER BLADE

NOTE: Remove safety key and battery before performing any maintenance!

NOTE: Only use identical replacement blades. LawnMaster ^® mower blade replacement part #111177128.

1. Stop the motor and allow the blade to come to a complete stop.
2. With the blade stopped, remove the SAFETY KEY and the BATTERY from the mower and store in safe location.
3. Remove the collection bag from the mower if attached.
4. Slowly turn the mower onto its side.
5. Wedge a block of wood between the blade and the mower deck in order to prevent blade from turning while the blade nut is being removed (Fig. 17).
6. Loosen the blade nut using a wrench or socket (not provided).
7. Remove the blade nut by turning counter-clockwise, and then remove the blade.
8. Place the new blade on the shaft. Make sure it is installed with the curved ends pointing up toward the mower deck and not down toward the ground.
9. Thread the blade nut on the shaft and finger tighten.
10. Torque the blade nut down using a torque wrench (not provided) to ensure the bolt is properly tightened (Fig. 18).

NOTE: Make certain all parts are replaced in the exact order in which they were removed.

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.

2. Turn mower on its side and clean grass clippings that have accumulated on the underside of the mower deck.
3. Wipe the mower clean with a dry cloth.
4. Check all nuts, bolts, knobs, screws, fasteners, etc., for tightness.
5. Inspect moving parts for damage, breakage, and wear. Have repairs made on any damaged or missing parts.

6. Store mower indoors in a clean, dry place out of the reach of children.

7. Do not store near corrosive materials such as fertilizer or rock salt. To lower the handle before storing:
