9. Maintenance and repair
9.1 General
WARNING
Electric shock
Work on electrical components may be
performed only by qualified electricians.
At a minimum, the following safety measures
must be taken before any work on electrical
components is done:
•
Isolate, lock and tag out.
•
Check to ensure the absence of voltage.
•
Ground and short-circuit the product.
• Cover any live parts in the surrounding area.
WARNING
Hot surfaces
Risk of burns from hot surfaces
The hot surfaces of a motor could cause burns.
Motor surfaces may only be touched with
appropriate gloves or after the motor has been
shut off for an extended time.
WARNING
System pressure
Hydraulic pressure
Lubrication systems are pressurized during
operation. Centralized lubrication systems must
therefore be depressurized before starting
assembly, maintenance, or repair work, or any
system modifications or system repairs.
NOTICE
Incorrect spare parts
Nullification of warranty
Only original SKF spare parts may be used. Unauthorized
alterations and the use of non
-original spare parts and
accessories are prohibited and nullify the statutory
warranty.
NOTICE
Lubricant
Damage due to contaminated lubricant
Only fill with clean grease. The purity of the lubricants used
is the decisive factor in the service life of the pump and the
lubricated machinery elements. Only fill grease via the fill
connection.
SKF products are low-maintenance. All connections and fittings
must be regularly inspected for proper seating to ensure proper
function. If necessary, the product's exterior can be cleaned
using mild cleaning agents that are compatible with the
product's materials (non-alkaline, non-soap).
For safety reasons, the product must be disconnected from
the power supply. Do not allow any cleaning agent to enter the
interior of the product during cleaning.
The interior of the product does not need to be cleaned.
The interior of the product must be cleaned if incorrect or
contaminated lubricant is accidentally filled into the product.
Contact the SKF Service department if this occurs.
Dismantling of the product or individual parts of the product
within the statutory warranty period is prohibited and voids any
claims.
The maintenance intervals are determined depending on the
specific conditions of the application.
The criteria are machine-specific settings such as lubricant
quantity, ambient and operating conditions, and the purity of
the lubricant used. Due to these conditions, the customer
defines and maintains the maintenance intervals.
If the reservoir has been emptied, the entire system must be
bled after refilling; see Chapter 6.6 Attachment of a gear pump
unit"Venting an MKU/MKF/MKL centralized lubrication system."
9.2 Maintenance schedule
Maintenance intervals vary depending on the system and are
affected by environmental factors such as dust and heat. The
maintenance intervals are therefore defined by the system
manufacturer.
