Removal Procedure

NOTE: Failure to use the anti-static mat SA9502Z properly may result in damage to the cluster electronics.

NOTE: Do not touch or bump the pointers of the gages. If a pointer is moved from its position, the calibration of the gage will be affected and the gage will no longer be accurate. If a pointer is moved, the cluster assembly will need to be replaced.

IMPORTANT: If the lens/mask gets dirty it can be cleaned by following the procedures in this manual. If a dial face gets dirty it can be cleaned by using glass cleaner and a lint free rag.

Remove the instrument panel cluster assembly. Refer to Instrument Cluster Replacement
Thoroughly clean your hands with soap and water to remove any oil or other substances which could damage the cluster. If unable to clean your hands, an alternative is to wear surgical gloves during all procedures.
IMPORTANT: It is strongly recommended that rubber gloves, e.g., surgical gloves, be worn while performing removal and installation procedures to prevent grease, smudges, scratches, and fingerprints.
Place the SA9502Z down on the work area. In order to ground the mat, connect the alligator clip to a large metal object, e.g., work bench, making sure that the attaching point is a bare metal surface and not painted or coated. Also put the wrist strap around one of your wrists.
Place a clean, dry, soft, material cloth on top of the anti-static mat.
Place the instrument panel cluster assembly face down on the cloth and the anti-static mat.
