marked with "PUSH". Open the air intake grill and then take out the healthy filter.
HOW TO CLEAN THE AIR FILTER
Wash away dust from the air filters with clean water or vacuum the filter with an electric household vacuum cleaner.
HOW TO DISMANTLE CLASP
Concrete dismantle method: use the similar tool in Figure b, align the clasp core and insert it, as Figure a is shown. The
inserted depth is about 3mm, as shown in Figure c, which the clasp is detachable. When you hear a sound, buckle the
clasp base with your hands to take out the clasp.
Note: If you insert it too deep, the clasp might be blocked, compulsory dismantle will damage the clasp and it might

separate the clasp base and core axis, then it is dismantled.
