16. If the mower should start to vibrate abnormally, release the bail handle, wait for the blade to stop and remove the safety key and battery pack,

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 bail handle to turn mower off, wait for the blade to stop and remove the safety key and battery pack, 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 safety key is in the mower.  
7. Always remove safety key and battery pack before adjusting, cleaning, repairing, inspecting, transporting, storing or leaving the mower.

NoTE: Certain types of grass or grass conditions may require varying  
the height of the mower deck. Grasses of mature lawns often are  
seriously injured when mowed shorter than 1-1/2 inches (38mm), and  
a height of 1-1/2 to 2 inches (38mm) to (51mm) is preferred on large  
lawns.  
1. Before making any adjustments, release bail handle to turn mower  
off, wait for blade to stop, and remove safety key.  
2. Your mower features the Black & Decker one touch wheel height  
adjustment system. This system will adjust all four wheels at the  
same time.
