Maintenance work must be done after the machine is turned off
Before performing any operation, make sure the machine is on a flat road surface and use a
parking brake to avoid any movement.
Keep the machine clean, which helps to find damaged parts
When cleaning the machine, avoid splashing the high pressure water column into the radiator,
heat exchanger and engine compartment.
When adding grease to the grease gun, carefully clean the oil gun nozzle to prevent mud, dust or
other foreign matter from contaminating the grease, resulting in reduced or no lubrication effect.
Adequately lubricate each lubrication point
When refueling or changing oil, use the same type of oil as recommended oil
