Hydraulic Adjustments pg.12.

Check to see if the Spinmaster grip cylinder piston

seals are leaking. The cylinders will be hotter than

the hydraulic motor if they are leaking internally

and the Spinmaster would slow down. To repair

the grip cylinders, See Drawings pg.56,58.

The Spinmaster motor could be leaking internally

causing the Spinmaster to slow down and the mo-

tor would also run hotter than normal. To repair

the motor see Drawings pg.62.

 Check that the pressure and tank hydraulic line quick

disconnects are properly and securely connected.

See Power Hook-Up pg. 11.
