MAINTENANCE
SERVICE PROCEDURE
ADJUSTING IN VERTICAL DIRECTION
1.
To determine the amount of adjustment, measure clearance B,
then subtract 2 mm and record the result (amount of
adjustment).
Example
If clearance B = 5 mm (0.197 in):
Amount of adjustment = 5 - 2 = 3 mm (0.118 in)
2. Loosen bolts (9) (inside, outside: Total 4) to a point where there
is no more reaction from the spring.
3.
Loosen bolt (1) (inside, outside: Total 8) . When doing this, do
not loosen it more than 3 turns.
4.
Using a bar, pull up up-down guide (5) to set clearance C to 0,
then remove shims of a thickness equal to the amount of
adjustment measured in Step 1.
5.
After removing shims (7), add them on top of shim (8).
(Left, right, inside, outside: Total 8 places)
When doing this, check that the total thickness of shim (7) and
shim (8) is the same after adjustment as it was before
adjustment at all places.
Discarding shims or adding shims will result in improper
function of the built-in spring.
REMARK
There are two types of shim thickness: 1 mm (0.039 in) and 2 mm
(0.079 in).
