KNOW YOUR WINCH Know Your Winch Before you begin, you should familiarize yourself with your WARN winch and each of its components. Hydraulic For hydraulic winching applications, no product performs better than a WARN Industrial winch. Powerful hydraulic motors allow for extended duty. Hardened steel, two-stage planetary gear trains deliver efficient and reliable operation plus fast line speeds. Like their electric cousins, these products comply with world-wide quality and safety standards. The pressure rating of the winch motor is determined by (a) the maximum allowable pressure at the motor inlet port and (b) the maximum allowable pressure drop across the
FINAL ANALYSIS AND MAINTENANCE
• Keep winch free of dirt, oil, grease, water and other substances. Remove any overflow grease from bearings. • Check all mounting bolts and make sure they are tightened to proper torque. Replace any damaged fasteners. • Periodically check all hydraulic connections to be sure they are tight and free of corrosion. Periodic Preventive Maintenance
WARNING Never exceed the maximum recommended hydraulic pressure or flow for any of the components used. WARNING Always use a tandem- center type control valve ( A & B work ports blocked) to insure proper brake operation. WARNING Always make sure all hydraulic system components are functioning correctly. WARNING Never use a standard motor valve.
• Check rope for visible damage every time winch is operated. Examples of damage are: cuts, knots, mashed or frayed portions, and broken strands. Replace rope immediately if damaged. Failure to replace a damaged rope could result in breakage. • If winch drum continues to turn after controls are released, brake may need to be replaced.

motor. Pressure drop is defined as the difference between the inlet pressure (P1) and the outlet pressure (P2) at the winch motor. Exceeding the maximum inlet pressure may damage the motor. Exceeding the maximum pressure drop may cause failure of winch components. HYDRAULIC FLUID: The hydraulic fluid used with the winch must be an extreme pressure, anti-wear hydraulic oil with oxidation and corrosion inhibitors. It must contain a foam suppressant, and have a viscosity rating of 100-300 SSU at 15-45 °C.

Pre-Install Checklist 1 Check to see that you have received the following: • The winch • The winch mounting hardware 2 Upon removing winch from packaging, check for damage including bent or cracked tie rods, tie bars, or housings. Correct any damage before installing winch. 3 Make sure the environment surrounding winch and control pack is free of : • Combustible vapors • Chemical fumes • Oil vapors • Corrosive material 4 Make sure that the air temperature surrounding the winch and control pack stays within 120° F (49° C) and -20° F (-29° C).
