4-4 Fixing o body and guide
(1) Remove the locking adhesive rom the ixing bolts and
clean them thoroughly. Apply locking adhesive at the
end o the screw. For the curing time, re er to the
catalog o the adhesive used, and take this into
consideration when mounting the product on the
machine.
The procedure or cleaning the ixing bolt is as ollows.
1) Remove the residue o locking adhesive on the
removed bolt using an organic solvent. I
necessary, use a brush to physically peel and
clean o the residue more e ectively.
2) Remove the locking adhesive rom the emale
thread in the same way.
Be care ul to prevent the locking adhesive and
dust rom entering the sliding part.
Do not wipe the grease o the guide.
3) Since organic solvent can be dangerous, re er to
its MSDS and take appropriate measures or sa e
use.
(2) As shown in the igure on the right, push the body down to the re erence mounting
sur ace at the port side or auto switch mounting side (Table 1) and tighten it
temporarily with the ixing bolts using a hexagon wrench. Then, tighten to the torque
speci ied in Table 2 using a torque wrench or torque driver.
The re erence mounting sur ace has thin

！ Caution
Tighten to the specified torque.
Insufficient torque can cause
accuracy failure and play at the
guide. Excessive torque can
cause deformation of parts,
operating failure, and accuracy
failure.
(3) Turn the loating part lightly and check there is no
excessive resistance.
Note) When turning the loating part, use the
wrench lat o the rod. I the rod is gripped
by pliers, etc., air leakage can result. Since
the MXQR6 and 8 do not have wrench lats,
use the loating bushing instead.
4-5 Mounting accessories
(1) Mount the adjuster parts to the
appropriate direction shown in the igure
on the right.
(2) When assembling the adjuster parts ( or
extension end) and stopper parts, make sure
