Tulsa planetary winches are shipped from factory with SAE 90
EP gear lube in the gearbox and SAE 20-20W motor oil in the
brake section. This oil should be satisfactory for operation in
ambient temperatures from -10° F to +110° F. If your work calls
for operation in temperatures outside this range, contact Tulsa
Winch for recommendations.
The hydraulic system driving the winch should use only high
quality hydraulic oils from reputable suppliers. These oils should
contain additives to prevent foaming and oxidation in the system.
All winch hydraulic systems should be equipped with a return line
filter capable of filtering 10-micron particles from the system.
