CHANGES
1.
Place an adequate container under the drain plug.
2. Remove the filler and drain plugs and allow the oil to drain out.
& The
oil
will drain better
if
it is warm.
3.
Wait for a few minutes until all the oil has drained out, then screw the drain plug back
on
after first chan-
ging the plug seal.
4. Fill with new oil until it reaches the level mark.
Do not mix oils
of
different makes or specifications
and check that the oil is highly resistant to foaming and is EP rated.
5.
Tighten down the filler plug after changing its seal.
The gear unit may be supplied with
or
without lubricant, as requested by the User. The quan-
tity
of
charge oil required
is
specified in the Sales Catalogue. This specification
is
however,
approximate, and reference must always be made to the mark on the level plug, the placement
of
which depends
on
the mounting position specified in the purehase order.
Life lubricated gear units which are not subject to external contamination do not normally require pe-
riodic lubricant changes.
lf
the same type
of
oil as that already in use is not available, drain the gear unit
casing completely and wash its interior thoroughly with a light solvent before refilling with the new lubricant.
A
lf
a leak is found, identify the cause
of
the fault and repair it before topping
up
the lubricant
~
and operating the unit.
Lubricants, solvents and detergents are toxic/harmful to health:
I.\
-they may causa irritation
in
direct contact with the skin
~
- they may cause intoxication if inhaled
• - they may
be
fatal if swallowed.
Handle them with care using suitable individual safety equipment.
Do
not dump them into the environment
and dispose of
in
accordance with applicable legislation.
8.3 - CHECKING OPERATIONAL EFFICIENCY
• Remove any dust from the gear unit and motor casings.
• Check that the noise generated at continuous load does not vary. Excessive vibration or noise can indicate
wear of the gear train or failure of a bearing.
• Check the power absorption and voltage against the rated values given on the motor's nameplate.
• Check the wear of the friction surfaces and braking gasketon the brake motors (if fitted) and, if necessary,
adjust the gap.
• Check for lubricant leaks from the gaskets/seals, plugs and casings.
• Check all bolted couplings for wear, deformation and corrosion and tighten them down fully, but without
over tightening.
8.4 - CLEANING
Remove all dust and process waste from the gear unit. Do not use solvents or other produets that are incom-
patible with the unit's construction material and do not direct high pressure jets of water at the gear unit.
