Connecting the components
1. Connecting the knives: Remove the wheels and place the knives on the drive shaft. Make sure you place the knives correctly on both sides of the shaft. After
placing the knives, place the bumpers (wheel covers) to avoid any injury that may be caused by the knives.
2. For moist soils: When the depth of wet soil is less than 25cm you can dig with curved knives. When the depth is 25-40cm you should use regular knives.
3. To connect the groove, you must first remove the working depth regulator and replace the groove by adjusting its depth and height.
Maintenance
Due to the way the digger works and the vibrations created, the screws and fittings can loosen or even wear out during operation. These changes can affect
the function of the digger and cause damage to the digger. In order to reduce the wear of your digger, inspections of the digging sections should be carried out
frequently and proper maintenance should be carried out. This way the digger will have the best possible performance and longer life.
1. When a digger is new or has undergone significant repairs it should not operate for more than one hour with a large load. After 5 hours of use, you must
empty the oil from the engine and gearbox and install a new one. Then let the machine work for 3-5 minutes at idle to clean well. Refuel and inspect the ma -
chine every 4 hours. With the above actions the machine will operate at optimal performance for quite some time.
