3 Thank you for purchasing our BRAIT brand cultivator! Before starting to operate the cultivator, carefully read the manual. Always keep this manual for future reference. We hope you enjoy working with this equipment. 1. PURPOSE OF THE MOTOCULTIVATOR The motocultivator is intended for operation in areas with a temperate climate. The use of a motor cultivator is most effective at an air temperature of 1C 40C. The service life of the cultivator will increase significantly if you strictly follow all the rules for operation, maintenance and storage specified in this manual and in the “Engine Operating Instructions” installed on the cultivator. Do not rush to use the tractor immediately at full power. REMEMBER that the first 25 hours of operation are a run-in period for the engine and transmission mechanisms. Therefore, it is better to process the same area with a cultivator in several passes, gradually increasing the processing depth. Work on a motor-cultivator does not require special training, however, it should be noted that when working with a motor-block, certain skills are required. In the process of soil cultivation, the space between the cutters and the gear housing can become clogged with stones, wire and other objects. In this case, to avoid damage to the V-belts, it is necessary to turn off the cultivator and remove objects stuck in the cutters. If the soil will often come across small stones and roots, you should reduce the speed of rotation of the knives. To prevent oil from spilling out of the gearbox, engine crankcase and fuel from the fuel tank, the tractor should be mounted on the vehicle in the normal position. 3

4 2. SAFETY RULES WHEN WORKING WITH THE MOTORCULTIVATOR Use the cultivator only for its intended purpose. for the cultivation of land. Before starting work, always check that the cultivator is fully and correctly assembled. Check the correct installation and secure attachment of all tool elements. Learn how to quickly turn off the engine and tiller cutters. Do not leave a working cultivator unattended. Motocultivator is not intended for use by children or people with impaired motor functions, as well as people who are intoxicated, under the influence of drugs. Use ear muffs, goggles or face shield. It is forbidden to work barefoot or in open shoes; wear sturdy shoes to avoid injuries. Do not use a cultivator if wings and protective covers are not installed, and also if the slope of the site exceeds 10 degrees. Fill the tiller with gasoline only in the open air and when the engine is not running. If gasoline spills when filling the tank, be sure to change the starting place, move away at least 3 meters from the spill site. It is forbidden to fill gasoline with the engine running or hot. Do not smoke when refueling and when handling fuel. Gas vapors are highly flammable. Close the gas tank and gas canisters tightly. Start the engine carefully, keep your feet away from rotating knives. Do not use the tool in greenhouses and enclosed spaces to avoid poisoning by the products of the internal combustion engine. When working on slopes, refuel the fuel tank halfway to prevent gas spills. Move perpendicular to the direction of the slope. Always turn off the cultivator when leaving it unattended, as well as at the end of use, before cleaning or transporting. Pre-clean all stones, wire, glass and other objects that could damage the cutters of the cultivator or cause injury from the treatment area. During operation, do not approach a dangerous distance from the rotating milling cutters, keep the distance provided by the handles of the cultivator. Do not change the setting of the engine speed controller or operate at high engine speeds. Check the tiller regularly for malfunctions and damage. If any damage is found, stop using the cultivator immediately and take the device to the nearest service center for diagnosis and repair. All types of repairs, except cleaning and regular maintenance, must be carried out by an authorized service center. Gasoline cultivator is used for cultivating the land in gardens and garden plots.
