Using this manual
This manual includes information for the normal operation, maintenance, and service of the Series 45 K2
frame open circuit pumps. The manual includes a description of the units and their individual
components, troubleshooting information, adjustment instructions and minor repair procedures. Unit
warranty obligations should not be affected if maintenance, adjustment and minor repairs are performed
according to the procedures described in this manual.
Many service and adjustment activities can be performed without removing the unit from the vehicle or
machine. However, adequate access to the unit must be available, and the unit must be thoroughly
cleaned before beginning maintenance, adjustment, or repair activities. Since dirt and contamination are
the greatest enemies of any type of hydraulic equipment, follow cleanliness requirements strictly. This is
especially important when changing the system filter and when removing hoses or plumbing.
A worldwide network of Danfoss Authorized Service Centers (ASCs) is available should major repairs be
needed. Contact any Danfoss ASC for details. A list of all ASCs can be found in bulletin BLN-2-40527, or in
brochure SAW (Ident. No. 698266), or you can locate your nearest ASC using the distributor locator at

Safety precautions
Always consider safety precautions before beginning a service procedure. Protect yourself and others
from injury. Take the following general precautions whenever servicing a hydraulic system.
Unintended machine movement
W
Warning
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
To protect against unintended movement, secure the machine or disable / disconnect the mechanism
while servicing.
Flammable cleaning solvents
W
Warning
Some cleaning solvents are flammable. To avoid possible fire, do not use cleaning solvents in an area
where a source of ignition may be present.
Fluid under pressure
W
Warning
Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious
injury and/or infection. This fluid may also be hot enough to cause burns. Use caution when dealing with
hydraulic fluid under pressure. Relieve pressure in the system before removing hoses, fittings, gauges, or
components. Never use your hand or any other body part to check for leaks in a pressurized line. Seek
medical attention immediately if you are cut by hydraulic fluid.
Personal safety
W
Warning
Protect yourself from injury. Use proper safety equipment, including safety glasses, at all times.
