4.2 OIL, COOLANT AND FILTER
4.2.1 Lubricant and Hydraulic Oil
Oil is used in the engine and hydraulic equipment under extremely severe conditions (high temperature,
high pressure), and deteriorates with the use.
Always use oil that matches the grade and maximum ambient temperatures recommended in the
operation and maintenance manual.
Even if the oil is not dirty, always change the oil at specified interval.
Always be careful when handling it to prevent any impurities ( water, metal particles, dirt, etc.) from
getting in. the majority of problems with machines are caused by the entry of such impurities.
Never mix oils of different grades or brands.
Always add specified amount of oil.
If the oil in the work equipments is not clear, there is probably water or air getting into the circuit. In
such cases, please contact your SUNWARD distributor.
When changing the oil, always replace the related filter elements at the same time. Especially when
changing engine oil filter element before installation, apply specified fresh and clean oil to the new filter
element.
We recommend you have an analysis made of the oil periodically to check the condition of the machine.
For those who wish to use this service, please contact your SUNWARD distributor.
The hydraulic system has been filled with SAE 10W CD oil, when the machine is shipped from factory.
Do not use any hydraulic oil other than those recommended by SUNWARD. Failure to do so may cause
filter clogging.
When changing hydraulic oil, please clean up thoroughly the residual oil in pipes and cylinders.
4.2.2 Fuel
The fuel pump is a precision instrument. If fuel containing water or dirt is used, it cannot work properly.
Be careful not to let impurities get in when storing or adding fuel.
Always use the fuel specified in the Operation and Maintenance Manual.
Fuel may congeal depending on the temperature when it is used (particularly in low temperature below
-15°C
(
5°F
)
. It’s necessary to use the fuel that is suitable for the temperature.
To prevent humidity in air to condense in fuel tank to form water, top up oil tank after the work is
finished every day.
Before starting the engine, or when 10 minutes have passed after adding fuel, drain the sediment and
water from the fuel tank.
If there runs out of fuel, or if the filters have been replaced, it is necessary to exhaust the air from the oil
circuit.
