8.32.2 Installation

●

Reverse the disassembling sequence
when installing glasses (3), (4), (6) and
(8). Follow the procedures below to install
glasses (1), (2), (5), (7) and (9).

1. Clean the remaining adhesive and rubber

on cab frame (contact surface) with a knife
or scraper [5].

●

Remove the remaining adhesive and
rubber so that they will not affect the
application of new adhesive. Do not
scrape the original paint on the surface.
(Scraping of paint reduces the perfor-
mance of the adhesive.)

2. Clean the grease, dust and dirt on the cab

(8) and the glass (9) with unleaded gaso-
line.

●

Contaminant on the contact surface re-
duces the performance of adhesive.

●

Clean the black part on the back of the
glass.

●

After cleaning, dry the glass for at least
5 minutes.

3. Priming coat (10)

●

Priming paint expires 4 months after
production. Do not use expired paint.

●

Use the paint within 2 hours after it is
unsealed.

●

Use the paint within 24 hours even if it
is sealed again immediately after un-
sealing. (Dispose the paint 24 hours
after it is unsealed)

1) Make sure the adhesive paint and glass

priming paint are well agitated before
application.

●

If the priming paint is stored in a refrig-
erator, keep it under ambient tempera-
ture for at least half a day before agita-
tion.

●

(If the paint is unsealed immediately af-
ter it is taken out of a refrigerator, water
will condense on it.)

2) Always wash a used brush (11) with

unleaded gasoline before using it.

●

Check the brush for contaminants after
it has been washed.

●

Prepare two brushes for priming paint,
one for painted surface and the other
for glass surface.
