LUBRICANT & HYDRAULIC OIL SPECIFICATIONS
HYDRAULIC SYSTEM
Use premium quality lubricants with 100-200 SUS or 20-43 cSt viscosity at operating temperatures.
The hydraulic fluid’s specifications in the table below are for normal operating conditions. Extreme
environments or dirty conditions may require the use of different oils. Consult your New Leader dealer
or the Product Support Department at Highway Equipment Company for systems operating outside
normal conditions.

GEAR CASE LUBRICANT
Lubricate these assemblies with non-corrosive type SAE 90 E.P. (extreme pressure) gear oil
conforming to MIL-L2105 B multi-purpose gear lubricating oil requirements (API Service GL 4) with
ambient temperatures from 40 to 100 degrees F. Ambient temperatures below 40 degrees F. require an
SAE 80 E.P. lubricant; above 100 degrees F. use an SAE 140 E.P. grade oil.
GREASE GUN LUBRICANT
Use a waterproof ball and roller bearing lithium base lubricant with a minimum melting point of
300
°
F. This lubricant should have a viscosity which assures easy handling in the pressure gun at
prevailing atmospheric temperatures. The grease should conform to NLGI No. 2 consistency.
CHAIN OILER MIXTURE
Use a mixture of 75% No. 1 or No. 2 diesel fuel or kerosene mixed with 25% SAE 10 engine oil.
The lubricant distributor and/or supplier is to be held responsible for results
obtained from their products. Procure lubricants from distributors and/or
suppliers of unquestionable integrity, supplying known and tested products. Do
not jeopardize your equipment with inferior lubricants. No specific brands of oil
are recommended. Use only products qualified under the following oil viscosity
specifications and classification recommended by reputable oil companies.
