configuration.
• For the Model 111.11B Accumulator Thread the unit onto the boss adapter fitting and securely tighten
it with a strap wrench.
• For the Model 111.12C Accumulator Lubricate and torque the four mounting bolts in increments
(according to the pattern shown in the “Mounting Configurations” figure) to a final torque of 108 N·m
(80 lbf-ft).
2. Check the accumulator precharge pressure as described in the related procedure.
