Warning:Compressed valve springs have high tension against the valvespring compressor. Valve springs that are not properly compressedby or released from the valve spring compressor can be ejected fromthe valve spring compressor with intense force. Use care whencompressing or releasing the valve spring with the valve springcompressor and when removing or installing the valve stem keys.Failing to use care may cause personal injury.

Caution:Do not compress the valve springs to less than24.0-mm (0.943-in). Contact between the valvespring retainer and the valve stem oil seal can cause potentialvalve stem oil seal damage.

Compress the valve spring using the EN 8062 compressor and the EN 46119 adapter.
