NOTICE
*1) DO NOT mix ZINC-FREE Hydraulic oils with Hydraulic
oils containing Zinc. DO NOT mix Mineral Hydraulic oils
with Synthetic Hydraulic oils.
Mixing of the above oils, will reduce anti wear properties
and oxidation stability of the oil. Quick plugging of the oil
filters in the hydraulic system will occur.
*2) Refer to the chart GEAR OILS filed in volume 2 binder
for the released gear oil qualities and viscosity grades.
*3) Brake housings of swing gears manufactured by L&S
have no separate oil compartment, as brake disks are
lubricated by splash oil from gear box.
The lubricating instructions in this book refer to the
recommended grade specifications. Damages caused
by using lubricants other than specified are not covered
by the manufacturer's warranty.
