16. If the mower should start to vibrate abnormally, release the switch lever, wait for the blade to stop and unplug the mower, then check for the  
cause immediately. Vibration is generally a warning of trouble.  
17. Always wear proper eye and respiratory protection when operating the mower.  
18. The use of any accessory or attachment not recommended for use with this mower could be hazardous. Only use accessories approved by  
Black & Decker.  
19. Never overreach while operating the mower. Always be sure to keep proper footing and balance at all times while operating the mower.  
SLOPE OPERATION  
Slopes are a major factor related to slip and fall accidents, which can result in severe injury. Operation on all slopes requires extra caution. If you  
feel uneasy on a slope, do not mow it.  
1. Mow across the face of slopes; never up and down. Exercise extreme caution when changing direction on slopes.  
2. Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could cause a slip and fall accident. Tall grass can hide obstacles.  
3. Do not mow on wet grass or excessively steep slopes. Poor footing could cause a slip and fall accident.  
4. Do not mow near drop-offs, ditches, or embankments. You could lose your footing or balance.  
CHILDREN  
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and the mowing  
activity. Never assume that children will remain where you last saw them.  
1. Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator.  
2. Be alert and turn mower off if a child enters the area.  
3. Never allow children to operate the mower.  
4. Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child.  
GENERAL SERVICE  
1. Never operate mower in a closed area.  
2. Keep all nuts and bolts tight to be sure the equipment is in safe working condition.  
3. Never tamper with safety devices. Check their proper operation regularly.  
4. Keep mower free of grass, leaves, or other debris build-up. Allow mower to cool before storing.  
5. If you strike a foreign object, release switch lever to turn mower off wait for the blade to stop and unplug the mower and then inspect the  
mower. Repair, any damage, before starting and operating the mower.  
6. Never make any adjustments or repairs with the motor running or while the mower is plugged in.  
7. Always unplug electric mowers before adjusting, cleaning, repairing, inspecting, transporting, storing or leaving the mower.  
8. Check grass catcher components and the discharge guard frequently and when necessary replace with Black & Decker recommended parts only.  
9. Mower blades are sharp. Wrap the blade or wear gloves, and use extra caution when servicing them.  
10. Maintain or replace safety and instruction labels, as necessary.  
WARNING: GENERAL SAFETY WARNINGS AND INSTRUCTIONS FOR ALL TOOLS  
THIS TOOL CAN BE DANGEROUS. Follow all warnings and Safety Instructions in this manual. The operator is responsible for following  
warnings and instructions in this manual and on unit. Restrict use of this mower to persons who read, understand and follow warnings and  
instructions in this manual and on unit.  
STORE IDLE MOWER INDOORS. Mowers should be stored indoors in dry, secured area – out of reach of children.  
DON’T FORCE MOWER. It will do the job better and with less likelihood of a risk of injury at the rate for which it was designed.  
USE RIGHT APPLIANCE. Do not use the mower for any job except that for which it is intended.  
DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves, long pants and substantial, non-  
skid footwear are recommended when working outdoors.  
USE SAFETY GLASSES AND OTHER SAFETY EQUIPMENT. Use safety goggles or safety glasses with side shields, complying with applicable  
safety standards and, when needed, a face shield. Also use face or dust mask if operation is dusty. This applies to all persons in the work area.  
Also use a hard hat, hearing protection, gloves, safety shoes and dust collection systems when specified or required. Safety glasses or the like are  
available at extra cost at your local dealer or Black & Decker Service Center.  
DON’T ABUSE CORD. Never carry mower by cord or yank it to disconnect from receptacle. Keep cord away from heat, oil, and sharp edges.  
MAINTAIN MOWER WITH CARE. Keep cutting edge clean and sharp for best performance and to reduce the risk of injury. Follow instructions for  
lubricating and changing accessories. Inspect mower cord periodically and if damaged, have it repaired by authorized service facility. Inspect  
extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.  
AVOID UNINTENTIONAL STARTING. Don’t carry plugged-in mower with finger on switch. Be sure switch is off when plugging in.  
BEFORE USING, always visually inspect to see that the blade, blade fasteners and cutter assembly are not worn or damaged. Replace worn or  
damaged blades and fasteners in sets to preserve balance. Inspect the mower cord - ensure it is in good condition. Cord insulation must be intact  
with no cracks or deterioration.  
TO REDUCE THE RISK OF ELECTRIC SHOCK, this mower has polarized plug blades (one blade is wider than the other) and will require the  
use of a polarized extension cord. The mower plug will fit into a polarized extension cord only one way. If the plug does not fit fully into the  
extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the  
use of a polarized wall outlet. The extension cord plug will fit into the polarized wall outlet only one way. If the extension cord plug does not fit fully  
into the wall outlet, reverse the plug. If the extension cord plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do  
not change the mower plug, extension cord receptacle, or extension cord plug in any way.  
EXTENSION CORDS. Make sure your extension cord is in good condition. Cord insulation must be intact with no cracks or deterioration. Plug  
connectors must be undamaged. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw.  
An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating, which can shorten the life of the motor.  
The table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The  
smaller the gauge number, the heavier the cord.

CHECK FOR DAMAGED PARTS. Before further use of the mower, a guard or other part that is damaged should be carefully checked to  
determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage  
of parts, mounting, and any other conditions that may affect their operation. A guard or other part that is damaged should be properly repaired or  
replaced by an authorized service center unless otherwise indicated elsewhere in this manual.  
REPAIRS AND SERVICE. Repairs, maintenance and any adjustments not specified in this manual should be performed by Black & Decker  
authorized service centers or other qualified service organizations, always using identical replacement parts.

RECOMMENDED APPROXIMATE CUTTING HEIGHT  
The cutting height should be in the higher recommendation for warmer weather, lower for shade areas and for the last mow before winter. Follow  
the 1/3 rule, never cut off more than 1/3 of the total height of the grass. If lawn is too high to practice this rule, raise the cut height before mowing  
and then lower to desired height and mow again in a day or so.  
OPERATING INSTRUCTIONS

other major appliances on the same house circuit.  
WARNING: Make sure that other persons and pets are at least 100 feet (30.48 m)
