CAUTION

Figure 3 is pressure and pressure relief devices. Remember not to open the drain. If the oil is released

accidentally, remember to mark the spring 5 and mark the marbles 6, and restore the original state according to the order
shown. Otherwise, the thermal part of the engine will be damaged due to insufficient lubrication.

(3)The replacement of engine oil filter
Unscrew and remove the 2 screws (shown no.7), remove the cover (shown no.8). Slide off the engine oil filter (don’t use
anymore). Fit a new oil filter and the cover (shown no.8), screw and tighten the 2 screws (shown no.7).
