Description

Warning

Make sure that protective gear
like goggles and gloves are al-
ways worn.

When working with lubricants
there is a risk of an allergic reac-
tion.

Allergic reaction

Open the plug carefully and keep
away from the opening. Do not
overfill the gearbox when filling.

When opening the oil or grease
plug, there may be pressure
present in the gearbox, causing
lubricant to spray from the
opening.

Possible pressure
build-up in gearbox

Make sure not to overfill the
gearbox when filling it with oil or
grease.

Overfilling of gearbox lubricant
can lead to internal over-pres-
sure inside the gearbox which in
turn may:

•

damage seals and gas-
kets

•

completely press out
seals and gaskets

•

prevent the robot from
moving freely.

Do not overfill

After filling, verify that the level
is correct.

After filling, verify that the level
is correct.

The specified amount of oil or
grease is based on the total
volume of the gearbox. When
changing the lubricant, the
amount refilled may differ from
the specified amount, depending
on how much has previously
been drained from the gearbox.

Specified amount de-
pends on drained
volume

For lifetime reasons always drain
as much oil as possible from the
gearbox. The magnetic oil plugs
will gather residual metal chips.

Contaminated oil in
gearboxes

Hazards related to batteries

Under rated conditions, the electrode materials and liquid electrolyte in the batteries
are sealed and not exposed to the outside.

There is a hazard in case of abuse (mechanical, thermal, electrical) which leads
to the activation of safety valves and/or the rupture of the battery container. As a
result under certain circumstances, electrolyte leakage, electrode materials reaction
with moisture/water or battery vent/explosion/fire may follow.

Do not short circuit, recharge, puncture, incinerate, crush, immerse, force discharge
or expose to temperatures above the declared operating temperature range of the
product. Risk of fire or explosion.

Operating temperatures are listed in
