Steps
PUMP Inspection
before using
First, check whether the pump is in good condition and whether there are any missing accessories.
Next, firmly install the pump and motor. The two pulleys are in the same line, and the belt is moderately tight.
After installation, turn the pulley by hand to check whether it can rotate smoothly. If it is too tight or cannot rotate, generally is caused by the distance between the pump and the motor.
The pump must be filled with oil (No. 30 oil is recommended) and added to the 2/3 position of the oil detector. Too little oil might create noise, too much oil might create heat. The sticker on the fuel cap must be removed to keep airflow in the tank.
Before starting the motor, first release the pressure and turn on the water outlet switch so that the water can be absorbed faster. The recommended speed of the pump is 500~900r/Min. These are some steps for you to check before you start using the power sprayer!
maintenance
of the pump
Regarding the intensity of use, observe whether there is backwater. If not, it may be due to insufficient flow.
After each use, the residual liquid in the pump should be cleaned and discharged.
Regarding the oil, change the oil for the first 10–30 hours of use because the oil will be dirty after the first use. Then change it every 70 hours and pay attention to keeping the oil above the 1/2 position of the oil detector.
