1.3.6. WARNING - Safety risks during work with gearbox oil
Description
When handling the gearbox oil, there are several dangers to both personal injuries and product
damages! Following safety information must be regarded before performing any work with
the oil in the gearboxes!
Warnings and elimination
Warning Description Elimination / Action
-
Hot oil!
Changing and draining
gearbox oil may require
handling hot oil of up to 90 °C! Make sure that protective gear
like goggles and gloves are
always worn during this activity.
-
Possible pressure build
up in gearbox!
When opening the oil plug,
there may be pressure present
in the gearbox, causing oil to
spray from the opening! Open oil plug carefully and keep
away from the opening. Do not
overfill the gearbox when filling.
-
Do not overfill!
Overfilling of gearbox oil can
lead to internal over-pressure
inside the gearbox which in
turn may:
• damage seals and
gaskets
• completely press out
seals and gaskets
• prevent the manipulator
from moving freely.
Make sure not to overfill the
gearbox when filling with oil!
After filling, check the correct oil
level.
-
Do not mix types of oil!
Mixing types of oil may cause
severe damage to the
gearbox! When filling gearbox oil, do not
mix different types of oil unless
specified in the instruction.
Always use the type of oil
specified by the manufacturer!
-
Heat up the oil!
Warm oil drains quicker than
cold oil. When changing gearbox oil, first
run the robot for a time to heat
up the oil.
-
Specified amount
depends on drained
volume!
The specified amount of oil is
based on the total volume of
the gearbox. When changing
the oil, the amount of refilled oil
may differ from the specified
amount, depending on how
much oil has previously been
drained from the gearbox. After refilling, check the oil level.
