30 Maintenance
Hydraulic Oil
The most crucial element to the hydraulic system is the hydraulic oil. It provides the system with
vitality. The oil transports damaging contaminants to filtering systems, lubricates and provides anti-
wear protection against component corrosion.
Regular oil changes are vital to the lifespan of hydraulic system components. Overtime, particles in
the oil will deteriorate the hydraulic system, observation of the oil color change signifies oxidization
and the need to be replaced. At that time, the oil will appear cloudy or milky. Keep in mind
operational performance, load and environmental conditions are variables that determine the
frequency of hydraulic oil renewal.
Following stringent maintenance schedules and performing routine oil analysis are effective methods
of obtaining information to determine the cleanliness of the hydraulic oil.
Labrie Enviroquip Group
recommends that the hydraulic oil be replaced or filtered every 1000 hours and following any major
hydraulic failures. Failure to maintain hydraulic cleanliness to recommended guidelines may result
in failure of hydraulic components and void your warranty.
Oil Identification
The Alley-Gator Right-Hand
TM
has an oil identification tag that specifies the manufacturer’s brand of
hydraulic oil that your vehicle has been filled at the Labrie factory. When oil replacement becomes
necessary other equivalent oil by other manufacturers may also meet your application requirements.
The oil identification tag is located on the hydraulic tank. Replacement decals may be ordered from
the Labrie Parts Department.
