Discharge tube Danger 6.
Tips for Mowing Grass Avoid Cutting Too Low Fast Throttle Setting If the cutting width of the mower is wider than the mower you previously used, raise the cutting height one notch to ensure uneven turf is not cut too short. For best mowing and maximum air circulation, operate the engine at Fast. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut too low or totally surround the mower by uncut grass.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first 5 hours of use • Change the engine oil. Each use • • • • • • Check the tire pressure. Check the engine oil level. Check the safety system. Clean the mower housing. Check the parking brake. Check for loose parts. Every 5 hours • Check the cutting blade. Every 25 hours • Grease the front wheels.
Servicing the Engine Oil 5. Screw the oil dipstick fully onto the filler tube (Fig. 14). Unscrew the dipstick again and look at the metal end. If the oil level is low, slowly pour only enough oil into the filler tube to raise the level to the Full mark on the dipstick. Check the oil level daily or after every 8 hours. Change the oil after the first 5 operating hours and every 50 operating hours thereafter. Important Do not overfill the crankcase with oil because the engine may be damaged.
Servicing the Battery Installing the Battery Always keep the battery clean and fully charged. Use a paper towel to clean the battery and battery box. If the battery terminals are corroded, clean them with a solution of four parts water and one part baking soda. Apply a light coating of grease to the battery terminals to prevent corrosion. 1. Put the battery into the battery box in the chassis. 2. Using the bolt, washers, and nut, connect the positive (red) cable to the positive (+) battery post.
