(EU)
Clearance between Hydraulic Arm Shaft and Bushing
1. Measure the hydraulic arm shaft O.D. with an outside
micrometer.
2. Measurement the bushing I.D. with an inside micrometer, and
calculate the clearance.
3. If the clearance exceeds the allowable limit, replace the
bushing.

(3) Cylinder Safety Valve
Operating Pressure of Cylinder Safety Valve
1. Attach the cylinder safety valve to injection nozzle tester with a
safety valve setting adaptor.
2. Measurement the operating pressure of the cylinder safety
valve.
3. If the operating pressure is not within the factory specifications,
adjust by turning the adjusting screw (1).
4. After adjustment, tighten the lock nut (2) firmly.
NOTE
• Use specified transmission fluid (see page G-9.) to test the
operating pressure of the cylinder safety valve.
