Checking the oil level
Check oil-level by means of either oil in-
spection glass 1 or oil dipstick 4.
Oil-level must be within the red circle of
the oil inspection glass 1 or within the
markings on the oil dipstick 4.
Check whether the oil has a milky discol-
oration or contains water drops (for
measures, please refer to chapter 7 titled
“Trouble shooting / Milky colour of the oil,
water drops in the oil”).
Topping up oil
Do not mix different types of oil. Exclu-
sively use types of oil specified by
BLITZ.
Switch the compressor off and depressur-
ise.
Unscrew either the oil filler neck 3 or oil
dipstick 4 (cf. Fig. 3: Compressor aggre-
gate).
Slowly fill the oil until the oil level is either
within the red circle of the oil inspection
glass 1 or within the markings on the oil
dipstick 4.
Screw on the oil filler neck.
Types of oil
Given normal mounting conditions (cf. chap-
ter 3.1 “Mounting conditions”), fill compressor
oil of viscosity class VG 100 of the VDL group.
BLITZ will provide information on oil for spe-
cial applications.
