Daily maintenance
Check Engine Fluid Levels
Check the levels and condition of the lubricants and
coolant in the engine. Follow the manufacturer’s rec-
ommendations for quantity and type.
Check/Fill DEF tank uid levels
Rell DEF tank uids if necessary. You typically add
DEF uid when you rell the diesel fuel. You can use
any brand DEF uid that meets ISO 22241-1.
A remote ll spout is located on the on the front of the
stationary pump (Figure 4). DEF cleanliness is ex-
tremely important as contaminants can degrade the
life of DEF and system components. Filtering is recom-
mended when lling the DEF tank. Prior to lling the
DEF tank, clean the blue colored DEF tank ller cap
and surrounding area. Avoid lling the DEF tank from a
contaminated container or funnel and overlling of the
tank.

Check Tires
Check the condition of the tires on the stationary pump.
Do not tow the unit with bald, cracked, or damaged tires.
Check Hydraulic Oil
Check the level and condition of
the hydraulic oil. Fill it, if necessary,
with the same brand and type of oil.
Add only ltered oil. Use a lter cart
to pump oil into the tank. New oil
contains more contaminants than
Schwing approves for their machines.
Replace milky looking oil, which is a
sign of water contamination. Try to
determine the source of the water. If
the oil has turned milky quickly, such as from one day
to the next, then simply replacing the oil will not solve
your problem.
Bleed Moisture from Hydraulic Tank.
Bleed the water out of the bottom of the hydraulic oil
tank by opening the drain valve, at the bottom of the
reservoir. Place a drain pan under the drain valve, open
the valve, and watch the liquid as it leaves the valve.
When the liquid changes from water to clean oil, close
the valve. Because of condensation, which increases
with dramatic heating–cooling cycles, there may be a
small amount of water in the tank every day. However,
it should settle to the bottom of the tank overnight. The
water that is drained should be clean and so should the
oil that follows it.

Check the Di󰀨erential Cylinder Rod Packings
With the engine turned o󰀨, remove the waterbox cov-
er. Remove the waterbox safety guard, or use a ash-
light and look through the waterbox safety guard holes.
Check for excessive hydraulic oil around or below the
di󰀨erential cylinder rod. Excessive oil in the waterbox is
an indication that the rod packings are worn out. Failure
to replace worn rod packings will result in water and de-
bris from the waterbox entering the di󰀨erential cylinder,
damaging the cylinder components and contaminating
the hydraulic oil. You should replace your di󰀨erential
cylinder rod packings every year.
