1. Don't let your engine run out of fuel.
First, your engine needs to be well lubricated to prevent the Lawn mower steering parts from overheating and smoking. If your lawn mower runs out of gas and is still running while you are doing yard work, you will either pay for engine repairs or pay for a new lawn mower. Check your oil before every use!

2. Don't let your radiator coolant become low.
This only applies to liquid-cooled lawn mowers. The engine will overheat and get stuck without coolant! You need to check the coolant level before each use!

3. Don't let your engine choke.
Remove dust and grass from the engine cooling fins. Your engine needs air circulation to prevent overheating. However, if your engine overheats, it may lock up, or even worse, cause your lawn mower to overheat, smoke, and then catch fire!

4. Don't hit the stump when mowing the grass.
If you hit a tree stump with a push lawn mower, you are likely to bend the blades and crankshaft. This will result in very expensive lawn mower repairs.

5. Do not try to quickly rewind the rope or barbed wire with the lawn mower.
Although your lawn mower will complete the job much faster than you, it is not a very cost-effective method. You may eventually need an overhaul. Here are some signs of damage to the lawn mower spindle.

6. If the safety equipment is not working properly, do not operate the lawn mower.
Before starting the mower, check all safety equipment. If the operator follows the safety instructions, most accidents involving lawn mowers can be avoided. No machine is worth the injury or death of your loved ones!

7. Do not let the lawn mower deck be blocked by grass and debris.
After each use, remove dirt, grass and debris from the top and bottom of the lawn mower deck. This will allow your pulleys and belts to move freely without overheating. You can flush the deck with a hose. When finished, simply engage the lawnmower blades and let them rotate for a few minutes to induce drying and reheat the bearings.
