7. Adjust the "open" lock side of the front window
assembly.
1) After adjusting the "close" lock side of the
front window in step 5, raise the front win-
dow assembly to the ceiling.
2) Check the following on the "open" lock
side of the front window assemblies at the
rear right and left of the operator's cab.
Check the working condition of right
q
and left locks (20).
Check that right and left stopper rub-
q
bers (22) are in contact with the front
window assembly and they have
bending allowance of 1.5 – 3.0 mm.
Check that limit switch (23) is pushed
q
back 4 – 7 mm by the front window
assembly.
a Since the position of limit switch (23)
cannot be adjusted, the "open" posi-
tion of the front window assembly is
decided within the functioning range
of this switch.
a Limit switch (23) is installed so that
the wiper will not move even if the
wiper switch is turned ON by mistake
while the front window assembly is
"open". If the wiper operates while
there is not the front glass, it will fall
into the cab and break down.
a To see if limit switch (23) is effective,
turn the key switch ON and then turn
the wiper switch ON while the front
window assembly is "open". If limit
switch (23) is effective, the wiper
does not operate at this time.
After the above check, if the front window
q
assembly needs to be adjusted, perform
the following.
3) Close front window assembly (13).
4) Loosen striker plate (24).
5) Remove cover (25).

6) Loosen locknuts (26) of right and left rub-
ber stoppers (22) and move right and left
rubber stoppers (22) back so that the front
window assembly will not touch the right
and left rubber stoppers (22) when it is
"open".
7) Set the rubber stoppers so that limit switch
(23) will be pushed back 4 – 7 mm by the
front window assembly (13) (while it is
"open").
8) Adjust the working condition of lock (20)
and tighten 2 striker plate mounting bolts
(27).
