Step 10: Attach the pump head cover. For the pump
head cover, the thick part of the center section of the fin
should be on the bottom when attaching, looking at it
from the exhaust/suction outlet. Use the torque
screwdriver No.2 (2.0 Nm) when tightening the small
pan head screws (w/M4×12S) × Qty.5. Tighten the
screws in order from (1) to (5). In addition, make two
passes around (1) through (5) when tightening the
screws, to ensure proper tightening.
*Be sure to always follow the appropriate tightening
torque. Failure to do so can lead to leakage.
