Change the oil for temperature reasons
Your Schwing unit was delivered with Mobil
Univis N46 hydraulic oil. This multi viscosity oil
should work nicely for any temperature between
-20˚ F and 100˚ F. If you have chosen to change to
a regular viscosity oil, pay close attention to the
paragraph below.
Change hydraulic oil every six months if you live in
a geographic location where seasonal temperature
changes are drastic. If you save the used oil in clean
barrels and properly store the barrels, you can reinstall
this oil when the weather changes back. You can use
the oil for a maximum of two six-month seasons.
If you ignore proper storage proce-
dures, the oil will become contaminat-
ed and will cause damage to the ma-
chine if reused. Contact your hydraulic
oil dealer to obtain clean barrels and
proper storage procedures. If you do
not own a filter cart for oil transfer, con
-
sider buying or renting one.
Changing oil - boom slewing gearcase
Do this procedure when the oil is warm. When the oil is
cold, it does not drain easily, and it does not rinse dirt
and contamination off the gears. You must, however, be
sure that the oil is not hot enough to burn you.
Do not change oil when the temperature of the oil is
over 50˚C. Severe burns could result.
1. Stop the motor, and put the “Do Not Operate” sign
on the control panel.
2. Remove the boom slewing drive cover. Do not do
this with the motor running, as you will be exposing
a pinch point until the cover is replaced.
3.
Remove the breather filter and the dipstick/fill plug
(Figure 13). Wash them both in solvent. Never use
gasoline!
4. Remove one of the gearcase drain plugs, and let
the old oil drain into a pan.
5. Rinse the gear case with cleaning solvent or fresh
hydraulic oil. Never use gasoline! Let it drain out
immediately. Do not reuse this oil.
6. Replace the drain plug.
7. Fill the case to the proper line on the dipstick. You
will have to fill very slowly because of the thickness
of 90W gear lube.
8.
Replace the breather filter, the dipstick/fill plug,
and the pinion gear cover.
