3-1. GENERAL.
The objective of this section is to present the operator with engine and compressor lubrication instructions Proper
lubrication is essential to operating life of any machine Always check oil levels of both the engine and compressor before
starting either unit.
3-2. OIL VISCOSITY.
The viscosity of oil is greatly influenced by ambient
temperatures at the site of operation. Figure 3-1 shows
the viscosity of oil recommended for use in the model
CAPITANO-PD When ambient temperatures fall below
the limit of the oil selected, the starting performance of
the compressor unit will be affected, but no equipment
damage will be caused. Since a too viscous oil can
cause starting difficulties, the choice of viscosity grades
during winter operation should be governed by the
ambient temperature prevailing at the time of engine
starting.
Oil
changes
resulting
from
ambient
temperature
changes
can
be
avoided
by
using
multigrade oils All viscosities are subject to oil change
intervals recommended in Table 2-2.
3-3. LUBRICATION OF ENGINE.
The
engine
is
splash
lubricated.
A
scooper,
incorporated into the connecting rod cap, forces oil
through drilled passages to lubricate the cylinder and
connecting rod bearings.

The engine oil should be changed regularly according to the PMCS schedule (Table 2-2)
