5.3.3 Non-drive Head Plate
1.
Refer to Figure 1, detail B. Look at the oil level in the
sight-glass (11) on the non-drive head plate (12):
If the oil level is below the minimum level mark (19),
continue at Step 2 to add more oil.
If the oil level is above the maximum level mark (18),
drain oil from the blower until the level is correct: refer
to Section 5.5.
2.
Refer to Figure 1. Remove the oil filler-plug (17) from
the filler port on the top of the non-drive head plate
(12).
3.
For new oil of the correct type (see Section 2.6)
through the filler port and into the head plate until
the oil-level reaches the maximum level mark (detail B,
item 18). If the oil level goes above the maximum level
mark (18), drain oil from the blower until the level is
correct: refer to Section 5.5.
4.
Refit the oil filler-plug (17) to the filler port on the top
of the non-drive head plate (12).
5.4 Inspect the system installation
Note:
Where possible, we recommend that you investigate the
cause of any damage or corrosion, and implement corrective
measures to prevent any future damage of components.
Use the following procedure to inspect the system
connections:
1.
Inspect all of the system pipelines and connections
and check that they are not damaged or corroded and
that they are sufficiently leak-tight. Repair or replace
any damaged or corroded component and seal any
leak found.
2.
Inspect the drive/transmission system and
adjust, repair or replace as necessary: refer to the
manufacturer’s instructions supplied with your drive/
transmission system.
5.5 Change the oil
Ensure that you use the correct grade of oil and that
the oil levels in the blower are correct. If you do not, the
blower will probably be damaged during operation, or
its performance may be affected.
WARNING
You must take care about the oil temperature. Please
wait at least two hours after the last running of the
blower to empty the oil casings to let the oil cool -down.
