Slope Operation

Slopes are major factors 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.

•  Mow across the face of slopes; never mow slopes 

following an up and down traverse. Exercise extreme 

caution when changing direction on a slope.

• 

Watch for holes, ruts, bumps, rocks, or other hidden 

objects. These may cause an unexpected slip or fall.

• 

Do not mow on wet grass or excessively steep slopes.  

Poor footing could cause a slip and fall accident.

•  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 

machine and the mowing activity. Never assume that children 

will remain where you last saw them. 

• 

Keep children out of the mowing area and under the 

watchful care of a responsible adult other than the 

operator.

•  Stay alert and turn the machine off if a child enters the 

area.

• 

Never allow children to operate the machine.

• 

Use extra care when approaching blind corners, shrubs, 

trees, or other objects that may block your view of a child.

Service

• 

Keep all nuts and bolts tight.

• 

Never tamper with safety devices. Regularly check to 

ensure these devices are in place and in proper working 

order.

•  Keep the mower free from grass, leaves, or other debris 

buildup.

• 

If you strike a foreign object, stop and inspect the 

machine. Repair, if necessary, before restarting.

• 

Never make any adjustments or repairs with the engine 

(motor) running. Always unplug electric mowers before 

adjusting, cleaning, or repairing.

• 

Check the grass catcher components and the discharge 

guard frequently and replace with manufacturer’s 

recommended parts when necessary.

• 

Mower blades are sharp. Wrap the blade or wear gloves, 

and use extra caution when servicing them.

• 

Maintain or replace safety and instruction labels, as 

necessary.
