INTRODUCTION
• DO NOT stand on or use a hose as a step. DO NOT pull or apply external forces to the hose. The hose may fail
and cause injury.
• Keep all persons away from the working area. Mechanisms controlled by fluid power can become hazardous if a
hose fails. Lifted mechanisms can fall to the ground, machine steering may fail, etc.
• Stay clear of a pressurized hose assembly that has blown apart. Hose fittings can be thrown off at high speed and
a loose hose can whip around with great force.
• Hydraulic fluid can reach high temperatures. Allow fluid to cool before servicing the system.
• Escaping fluid under pressure may form a mist or fine spray which can flash or explode upon contact with an ignition
source.
• Vibration can reduce hose service life. Make sure all retaining clamps and/or devices are secured.
• Environmental conditions can cause hose and fittings to deteriorate. Inspect hydraulic hoses periodically. Replace
worn or damaged hoses and fittings.
Safety requirements for fluid power systems and components - Hydraulics (European stan-
dard PR EN 982)
Flexible hose assemblies must not be constructed from hoses which have been previously used as part of a hose
assembly.
Do not weld hydraulic piping.
When flexible hoses or piping are damaged, replace them immediately.
It is forbidden to modify a hydraulic accumulator by machining, welding or any other means.
Before removing hydraulic accumulators for servicing, the liquid pressure in the accumulator must be reduced to zero.
Pressure check on hydraulic accumulators shall be carried out by method recommended by the accumulator manu-
facturer.
Care must be taken not to exceed the maximum allowable pressure of the accumulator. After any check of adjustment
there must be no leakage of gas.
Danger of death by electrocution!
Pay special attention to the overhead power lines. Make sure the machine has sufficient clearance to pass in all
directions (also with raised or opened machine components). Also think of the radio aerial(s) or any other factory-
fitted accessory or parts which may have been added afterwards.
Should a contact between the machine and an electric power line occur, then the following precautions must be taken:
Stop the machine movement immediately, stop the engine and apply the hand-brake or parking brake.
Check if you can safely leave the cab or your actual position without direct contact with electric wires. If not, stay
in your position and call for help. If you can leave your position without touching the lines, jump off the last step or
support position to ensure that there is no contact between any part of your body and the ground at any time. Do not
touch the machine afterwards until power to the lines has been shut off. When people approach the machine, warn
them not to touch the machine but to ask the electric power supply company to shut off the power to the lines.
Engine safety
1. Keep the engine area clean of dust, chaff and straw to prevent the possibility of fires.
2. Never idle the engine in an enclosed area as harmful exhaust gases may build up.
3. Wear a suitable hearing protective device, such as ear muffs or ear plugs, if you are exposed to noise which you
feel is uncomfortable.
4. The cooling system operates under pressure which is controlled by the radiator cap. It is dangerous to remove
the cap while the engine is hot.
