material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may cause
injury or death. Make sure air stream is directed away from user and other personnel in the area. To pre-

Inspect all parts for damage and replace as necessary.
Use spring tester to apply test force of 26.6 lb (12 kg) to spring (5) and measure length of spring. Measurement should
be 2.05 in. (5.20 cm). Replace spring if measurement is not as specified.
Release test force from spring (5) and measure length of spring. Measurement should be 2.89 in. (7.34 cm). Replace
spring if measurement is not as specified.
Measure outer diameter of spring (5). Measurement should be 0.596 in. (15.128 mm). Replace spring if measurement is
not as specified.
