Instruction of Gasket A  

Attach Gasket A so the four 
protruding sections face the 
blower body and carefully

slots. 
If these protruding sections are 
not correctly located into the 
slots, air leakage will result.

If detached, re-fit the spring into the back 
of the piston by rotating it anti-clockwise
Remove the plastic cap before use. This 
cap is used to protect the special grease 
prior to fitting.
Never apply additional grease as this will 
likely cause damage or malfunction
