TROUBLE SHOOTING/CORRECTIVE ACTION GUIDE:

PROBLEM	CORRECTIVE ACTION
-Motor will not start	- Check fuse or circuit breaker to ensure
	power is to outlet
	- Check extension cord with another
	electrical device to ensure cord is good.
	- Call customer service representative
	1-800-544-6986
-Motor keeps slowing	- The underside of the mower may be
down	plugged with clippings. Turn mower off, wait
	for blade to stop and UNPLUG mower and
	clean out.
	- Grass may be too tall, try pushing at a
	slower pace, or raise cutting height.
	- Check blade sharpness and balance, and
	correct if required.
	- If mulching, there is too much grass.
	Turn mower off, wait for blade to stop and
	UNPLUG mower and attach discharge chute
	to disperse grass
-Runs but poor cut	- The blade may be dull. Turn mower off,
results	wait for blade to stop and UNPLUG mower
	and carefully check for sharpness.
	- Blade may be damaged (bent or badly
	chipped). Turn mower off, wait for blade to
	stop and UNPLUG mower and replace if
	necessary.
	- Grass may be too high or thick for cutting
	height. Turn mower off, wait for blade to stop
	and UNPLUG mower and raise cutting height.
-Excess vibration	- Blade may be loose. Turn mower off, wait
	for blade to stop and UNPLUG mower
	then check blade for tightness.
	- Blade may be bent or badly chipped.
	Turn mower off, wait for blade to stop and
	UNPLUG mower and replace if necessary.
	- Blade may be unbalanced. Refer to blade
	balancing section of instruction manual.
-Mower is hard to push	- Mower is too close to the ground with the
	amount of grass being cut. Turn mower off,
	wait for blade to stop and UNPLUG mower
	and raise cutting height.
	- Turn mower off, wait for blade to stop and
	UNPLUG mower and check wheels and
	axles to ensure all are rotating easily.
-Mower leaves clumps	- Turn mower off, wait for blade to stop and
of grass	UNPLUG mower and raise cutting height.
	- If mulching, there is too much grass.
	Turn mower off, wait for blade to stop and
	UNPLUG mower and attach discharge chute
	to disperse grass
	- Turn mower off, wait for blade to stop and

-Discharge/Bag plugging - Grass may be too wet, try again when

grass is dry.

-There is too much grass. Turn mower off, wait for blade to stop and UNPLUG mower and raise cutting height.

HERE ARE SOME HELPFUL HINTS TO GET THE MOST FROM YOUR BLACK & DECKER MOWER...AND KEEP YOUR LAWN LOOKING BEAUTIFUL

1.Lawns should first be mowed in the spring when the grass is about 2 1/2 to 3 inches high. Mowing too early restricts the grass root systems which renew themselves every spring. New grass should be clipped when it is about 2 1/2 inches high.

2.Do not remove too much grass blade surface at one time...never more than 1/3 of the leaf height during each cutting. Cutting too close “shocks” sensitive grass blades, resulting in a shallow root system and thus making it more difficult for your lawn to reach water in the soil.

3.Lawn care experts say that excessively close cutting is responsible for much of the difficulty experienced on many lawns. The depth and strength of the roots of grass are almost exactly proportional to its growth. Grasses of mature lawns often are seriously injured when mowed shorter than 1 1/2 inches, and a height of 1 1/2 to 2 inches is preferred on large lawns.

4.Mow your lawn when it is dry to avoid clumping of wet grass. If you have a choice, late afternoon is the ideal time for mowing, not only because the grass is dry, but also because the sensitive new cut area of the grass will not be exposed to intense sunlight.

5.Keep the mowing blade sharp for a nice clean cut. This improves the mower’s performance and enhances the look of your lawn. A dull blade shatters and bruises the tips of the grass. This impairs the healthy growth of your lawn and increases susceptibility to turf diseases. If the grass tips are bruised it causes a brownish colour and gives your lawn an unhealthy appearance. A dull blade may also pull up young seedlings.

6.Try to mow your lawn at the same (consistent) cutting height. While there are times when you should vary the cutting height with the changing seasons, a consistent cutting height produces a healthier, lovelier lawn with generally fewer weeds. Mow more frequently during periods of fast growth. Frequent cutting ensures that the lower, less attractive portion of the grass will not show.

7.If your lawn has grown too long, (a vacation, for example, may interrupt your cutting schedule) mow at a cutting height one or two positions higher than normal. A second pass at “normal” cutting height a few days later will put your lawn back on schedule. Changing the cutting height is a simple matter with Black & Decker’s One Touch Wheel Height Adjustment, which simultaneously adjusts all four wheels at once.

8.During the spring and fall, (or after an interruption to the cutting schedule) the grass will be longer and thicker. If the motor continually slows down while cutting, try setting the wheels for a higher cutting height. Excessive motor loading can result in uneven cutting, quicker discharge of the battery, and can cause the circuit breaker to trip, which stops the motor.

9.Three good ideas to enhance your lawn’s appearance: Vary the mowing direction frequently; mow horizontally on hillsides; (this is also a good safety practice) and do not forget to overlap the mowing path on each pass.

10.Always mow grass so that clippings are discharged onto cut lawn. This will keep your lawn looking fresh by avoiding “Cut Grass” build-up which will eventually brown and appear ugly.
