Screw tightening
• The screws and bolts must be tightened
with an appropriate tightening torque
according to the material and strength of
the installation area.
• Do not use an impact driver. Failure to
observe this may cause overtightening and
consequently damage to the screws.
• When a screw is tightened, make the
screw at a right angle to the surface. After
tightening the screws or bolts, perform
visual check to ensure tightening is enough
and there is no backlash.
