Multiquip EHTX44Y5 operation manual Steering Pressure Adjustment, Checking Steering Pressure

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.

WARNING

DO NOT depress the FOOT PEDAL with the 300-600 PSI gauge installed or the gauge will be ruined.
