Refer to Figure 31 for testing locations.
6. Engage the parking brake, and stop engine.
a. If the engine speed is not within specifications, refer to Engine Cannot Reach Top Engine Speed or Engine
Over Speeds (WP 0019).
b. If the charge pressure for Hydrostatic Pump is not within specifications, adjust the charge relief valve for
that circuit and perform the initial pressure test again. Refer to Charge Relief Valve Adjustment (WP 0030).
c.
If the implement pump standby pressure is not within specifications, perform Hydraulic Pump Test and
Adjustment (WP 0033).
d. If the brake pressure is not within specifications, perform Deceleration/Brake Pedal Test in this work
package.
