CAUTION
Damage due to mixing lubricant types
Mixing greases and oils which are based on different types of soap or oil can degrade their
lubrication properties.
Mixing low temperature grease with normal temperature grease can cause lumps to form in
the lubricant. This can result in thermal damage to the rolling-contact bearing.
Never mix greases that have different thickening agents and different base oils.
Regreasing
● Clean the grease nipples before regreasing, and then gradually press in an appropriate
type and amount of grease, as per the information on the lubricant plate.
The shaft must rotate so that the new grease can be distributed throughout the bearing.
The bearing temperature rises sharply at first, then drops to the normal value again after
the excess grease has been displaced out of the bearing. The chamber for the used
grease is designed for at least 10 regreasing sessions.
● To remove used grease, loosen the outer bearing cap.
Escaping oil at the bearing or oil escaping during regreasing is an indicator that the space
for the used grease has been over-filled. [ID 1025.01]
9.1.3 Cleaning the cooling system
Cleaning the cooling system
To ensure proper functioning of the machine cooling system, the cooling circuits, e.g., the
grilles, ducts, ribs, and pipes, must be free of dirt.
● Clean the cooling circuits regularly and remove all dirt.
● Clean the grilles and cooling ribs to remove any dust or dirt.
CAUTION
Risk of corrosion due to condensation
During machine operation, humid air can condense inside the machine. Condensation
can collect inside the machine. Damage such as rust can result.
Depending on the environmental and operating conditions, remove the condensation
water plugs or screw plugs to drain the water. When you have finished, reattach the
condensation water plugs or screw plugs.
If the motor is equipped with condensate drain holes and draining plugs, the water can
drain off automatically.
