MAINTENANCE
Checking Steering Pressure
Steering pressure is also checked at either one of the
pressure diagnostic couplers (Figure 48) under the right
grill guard. Check steering pressure at either coupler with
a 300-600 PSI gauge.
Figure 48. Steering Pressure Gauge
Run the engine at full RPM. The steering system's factory
settings are shown in Table 9, however some operators
may prefer a more responsive steering (higher pressure
required) and some operators may prefer a "softer feel"
(lower pressure required).
WARNING
DO NOT depress the FOOT PEDAL with the 300-600
PSI gauge installed or the gauge will be ruined.
