Things to remember when assembling
• Assembling instructions are dismantling instructions backwards.
• You do not need any extra force.
• Screwdriving order is as screws are numbered.
• Tightening torque for all screws is 22Ncm, use torque wrench.
• Installing parts from pushing springs is forbidden.
• Do not touch springs vhen dismantling or assembling.
• All spring contacts and PWB pads are sensitive to dirt and grease for instance
from hands.
• Be careful not to touch spring contacts or PWB pads with bare hands. Always use
gloves.
CCS Technical Documentation
• New protective tape needed for grip flex.
