MANIFOLD
The relief valve (R1) and (R2) pressure test should be
performed to make sure thatthe cutting unit circuit relief
pressures are correct.
NOTE: Thefrontcutting unitcircuitis protectedbyrelief
valve(R2).Therearcuttingunitcircuitis protectedbyre-
lief valve (R1) (see Hydraulic Flow Diagrams in this
chapter).
Procedure for Relief Valve (R1) and (R2) Pressure
Test
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine under load for
approximately ten (10) minutes.
2. Parkmachine ona levelsurfacewiththecuttingunits
loweredand PTOs witch off.Make sureengine isoffand
mow/transport lever is in mow. Apply the parking brake.
