Drilling-Fluid Pump Maintenance; Servicing The Drilling-Fluid-Pump Oil - Toro 4045 Operator's Manual

Checking the Hydraulic Lines and
Hoses
Service Interval: Every 2 years—Replace moving hoses.
Inspect the hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings, weather
deterioration, and chemical deterioration. Make all necessary
repairs before operating.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure that all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
• Keep your body and hands away from pin
hole leaks or nozzles that eject high-pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Seek immediate medical attention if fluid is
injected into skin.
Checking the Hydraulic System Test

The test ports are used to test the pressure in the hydraulic
circuits. Contact your Authorized Toro Dealer for assistance.
