WARNING
RECOIL UNITS ARE DANGEROUS. They must not be
dismantled without using suitable tools to compress the
spring safely. The spring pressure can cause serious
injury if suddenly released. Scrap units must be made
harmless by compressing the spring in a hydraulic press
and cutting through the end of the shaft before slowly
releasing the pressure.
