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 technican or bystanders.
To prevent uintended movement, secure the machine or disable / disconnect the mechanism while
servicing.
Flammable Cleaning Solvents
W
Warning
Some cleaning solvents are flammable. To eliminate the riskof 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.
The list of spare parts cannot be used when ordering parts for special TMTW versions. In this respect,
please contact the sales organisation for Danfoss Hydraulics.
