IMPORTANT Safe Operation Practices for Walk-Behind Mowers. This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death. tion which can cause drowsiness or affect your ability to operate this machine safely. I. General Operation 1. Read, understand, and follow all instructions on the machine and in the manual(s).
IMPORTANT DO NOT: Do not mow near drop-offs, ditches, or embankments. The operator could lose footing or balance. Do not mow excessively steep slopes. Do not mow on wet grass. Reduced footing could cause slipping. III. 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.
SAFE MOWING GUIDE gency. Learn how to cut and how to keep control of the mower at all times. Many mowers are started manually. When using a pull start or rope start, place your feet firmly and away from the blade. Hold the rope handle securely, but never wrap the rope around your arm or fingers for a “better grip”. The mower is designed for use by one person. Always mow alone. Never carry passengers. Carrying a passenger is dangerous for the passenger and the operator.
SAFE MOWING GUIDE bruises, or even put out an eye. Often the person hurt by a thrown object is a bystander such as a child, another family member or a neighbor. Keep people and pets completely away from the mowing area. Direct the mower’s discharge away from areas where people can be. Planning your mowing pattern has a double benefit. It can reduce chances of an injury and make the clean up after mowing easier.
SAFE MOWING GUIDE Use only original equipment or approved substitutions as service parts. If you need professional service, select a shop that is an Authorized Service Center for your brand of mower. If you plan to service the unit yourself, follow directions in the Instruction Book. in the rain is no fun and it is dangerous. Always seek shelter in an electrical storm.
SAFE MOWING GUIDE position when mowing and bagging. When bagging, slower ground speed will provide the best results. Change the mowing pattern slightly each time you cut. If you always cut the same way, the grass will develop a “set” and clippings will accumulate more heavily in some areas more than in others causing grass to get thinner in those areas. Do not service your mower over the grass. Spilled oil and gas can kill the grass. In tall grass or very heavy grass, do not try to cut it all at once.
STEPS TO FOLLOW BEFORE MOWING D D D D D D D D D D D Be sure to dress correctly. Wear hard shoes, not sandals or tennis shoes. Examine the blade. A blade that is bent, cracked, or damaged must be replaced with a factory replacement blade. Fill the fuel tank outside. Clean off spilled fuel. Read and follow the Owner’s Manual, the instructions with the engine, and the instructions with any attachments. Owner’s Manual instructions are for your safety and the safety of others. Exhaust fumes are dangerous.
