Bracket Installation Note
1. Install the bracket as shown in the figure.
End Of SieREAR SHOCK ABSORBER DISPOSAL (WGN)A6E7416287002021. Lay the shock absorber on a level, horizontal surface.
2. Using a 2—3 mm {0.08—0.12 in} drill bit, drill a
hole in the high-pressure side (area indicated by
A), and allow the gas to escape.
Warning
•The oil in the shock absorber is
pressurized and could spray out. Be sure
to drill slowly and carefully.
3. Using a 2—3 mm {0.08—0.12 in} drill bit, drill a
hole in the low-pressure side (area indicated by
B).
4. Place the shock absorber with the hole drilled in
Step 3 turned downwards. Move the piston rod up
and down several times to drain out the oil.
5. Cut the tube at the end of the shock absorber,
and completely drain the oil out.
6. Properly dispose of the waste oil according to
waste disposal laws.
