HANDLING PRECAUTIONS
Taping
When it is possible that the body or parts may be scratched
during the operation, apply protection tape before starting
work.
Example:
1. Before starting work, apply protection tape to bodysurfaces around parts to be removed and installed.
2. Before prying parts loose with a screwdriver or scraper etc., apply protection tape to the tip of the tool to avoid
scratching parts or painted surfaces of the body.
Battery
In order to prevent a short circuit while doing work on the elec-
trical circuit such as disconnecting a connector, first turn off
the ignition switch and disconnect the negative cable from
the battery terminal before starting work.
HINT: When battery voltage is required for operation of a
functioning part, connect the cable to the battery when need-
ed, and promptly disconnect it when no longer necessary.
CAUTION:
wWork must be started after approx. 20 seconds or longer
from the time the ignition switch is turned to the ºLOCKº
position and the negative (±) terminal cable is
disconnected from the battery.
wTo avoid erasing the memory of each memory system,
never use a back±up power supply from outside the
vehicle.
Fitting Adjustments
When removing and installing body panels which have a pre-
load value, after the installation refer to the page containing
the installation adjustment methods, and make adjustments
according to the required specifications.
HINT: When making adjustments, do not completely loos-
en the bolts and nuts of the part being adjusted. T ighten them
appropriately, and move the panels by hand to align them.

for details of which parts have received anti±rust treatment.
Body Sealer
If the body sealer is damaged (peeling, cracks, etc.) during
the operation, replace it with new body sealer.

off with a clean cloth dipped in a grease, wax and silicone re-
mover.
Undercoat
If the undercoat is damaged during the operation apply new
undercoat.
HINT:
wCover the surrounding area with masking paper to
avoid applying undercoat where it is not needed.
wDo not apply undercoat to high temperature parts
such as the tailpipe, or to drive parts such as the drive
shaft.
Rust Inhibitor
After removing and re±installing hinges and outer panel
parts, apply rust inhibitor to the parts.
HINT: If rust inhibitor gets spilled on other parts, promptly
wipe it off with a clean cloth dipped in a grease, wax and sili-
con remover.
Touch±Up Paint
If a small scratch is made in the body surface, correct the
scratch using touch±up paint the same color as the body col-
or.
