Hydrostatics Servicing Overview

Safety Precautions

© Danfoss | November 2020
This manual includes information on installation, maintenance, and minor repair of the MP1 motor. It
includes a description of the unit and its individual components, troubleshooting information, and minor
repair procedures.
Performing minor repairs may require the unit to be removed from the vehicle/machine. Thoroughly
clean the unit before beginning maintenance 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 Global Service Partners is available for major repairs. Danfoss trains and
certifies Global Service Partners on a regular basis. You can locate your nearest Global Service Partner
using the distributor locator at http://www.danfoss.com.
For detailed technical information about the MP1 motor, please see the
document.
Attention
Major repairs requiring the removal of a unit's center section, servo sleeves, or front flange voids the
warranty unless a Danfoss Authorized Service Center performs them.
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

Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
Secure the machine or disable/disconnect the mechanism while servicing to protect against unintended
movement.

Flammable Cleaning Solvents

Some cleaning solvents are flammable.
Do not use cleaning solvents in an area where a source of ignition may be present to avoid possible fire.

Fluid Under Pressure

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.
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. Use caution when dealing with
hydraulic fluid under pressure. Seek medical attention immediately if you are cut by hydraulic fluid.

Personal Safety

Protect yourself from injury whenever servicing a hydraulic system.
Use proper safety equipment, including safety glasses, at all times.
Hazardous Material
Hydraulic fluid contains hazardous material.
Avoid prolonged contact with hydraulic fluid. Always dispose of used hydraulic fluid according to state,
and federal environmental regulations.
