psi is recommended for maximum efficiency and ser-
vice. Do not exceed 3000 psi as this will damage
components  possibly  causing  serious  injury.
The Bush Hog control valve is pre-set at the factory
and should not be adjusted.

Troubleshooting  procedures  are  listed  in  Table  4-1.
If  the  problem  cannot  be  solved  or  replacement
parts  are  necessary,  contact  your  authorized  Bush
Hog dealer. Please have ready your machine name,
model  number,  serial  number,  purchase  date  and
exact cause or description of problem.
