MOWING TIPS

■ Make sure the lawn is clear of stones, sticks, wires, and other objects that could damage the lawn mower blades or motor. Do not mow over property stakes or other metal posts. Such objects could be accidentally thrown by the mower in any direction and cause serious personal injury to the operator and others.
■ For a healthy lawn, always cut off one-third or less of the total length of the grass.
■ Do not cut wet grass, it will stick to the underside of the deck and prevent proper bagging or mulching of grass clippings.
■ New or thick grass may require a narrower cut or a higher cutting height.
■ Clean the underside of the mower deck after each use to remove grass clippings, leaves, dirt, and any other accumulated debris.
■ When cutting long grass, reduce walking speed to allow for more effective cutting and a proper discharge of the clippings.

NOTE: Always stop mower, allow blades to completely stop, and remove the battery key before cleaning underneath the mower.

SLOPE OPERATION

WARNING

Slopes are a major factor related to slip and fall accidents that can result in severe injury. Operation 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.

WARNING

Please keep self-propelled at low speed when mowing up to a slope.

■ Mow across the face of slopes, never up and down. Exercise extreme caution when changing direction on slopes.
■ 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.
■ 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 power lever immediately.
■ Do not mow near drop-offs, ditches, or embankments; you could lose your footing or balance.

■ Stop mower, allow blade to completely stop, and remove battery key.
■ Lift the rear door.
■ Lift the grassbox by its handle to remove from mower.
■ Empty grass clippings.
■ Lift the rear door and reinstall the grassbox as described earlier in this manual.

Wipe the mower clean with a dry cloth occasionally. Do not use water.

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.

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. Contact with the blade could result in serious personal injury.
