LUBRICATION AND HyDRAULIC
OIL SPECIFICATIONS
NOTICE!
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.
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° F (4.44 to 37.77° C). Ambient temperatures below 40° F (4.44° C). require an SAE 80 E.P. lubricant; above
100° F (37.77° C). use an SAE 140 E.P. grade oil. Refill gear case with one and a half (1-1/2) pints (.70 liters) of
recommended lubricant.
GREASE GUN LUBRICANT
Use a waterproof ball and roller bearing lithium base lubricant with a minimum melting point of 300°F (148.8° C).
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.
