CAUTION!
Before working on the pressure washer,
disconnect the plug from the power supply socket.
Change Pump Oil
The pump was filled with standard 5W-40 synthetic oil at the
factory. Check the table below for compatible pump oil and
schedule of oil changes.
To change the pump oil, follow the instructions below.
1. Remove the detergent tank, and place a container under
the pump for waste oil. Use a wrench to loosen and
remove the oil draining nut located at the bottom of the
pump (Fig. 19).
2. Wait until the waste oil is drained completed from the
pump. Tilt the machine if needed to speed up the draining
process.
3. When the waste oil is completely drained, replace the oil
draining nut and tighten securely.
4. Flip up the pump cover and use your hand to loosen
and remove the oil measuring plug by screwing it
counterclockwise. Fill in the new pump oil from the oil inlet
(Fig. 20).
5. Check the oil level with the oil measuring plug. Make sure
the oil level is between the MIN. and MAX. indication on
the plug (Fig. 20).
NOTE: It's also possible to check the oil level through the
oil level window on the side of the pump. Make sure the oil
level is not passing the red dot on the window (Fig. 21).
Clean the Adapter Filter and the Nozzle
1. To ensure good performance, check and clean the adapter
filter (Fig. 22). Remove the filter and rinse with warm water
to prevent any foreign matter from clogging the pump
(Fig. 23).
