Safety instructions:
General safety instructions:
1. Please familiarize yourself with operator’s manual before putting machine
into service.
Make sure that you have obtained, read and understand any additional instructions
relating to special accessories for machine.
2. Only explicitly authorized personnel may operate, maintain or repair the
machine.
Observe the permissible minimum legal age limit!
3. Use only trained or instructed personnel, clearly determine the responsibility of
the personnel for operation, set up, maintenance and repairs.
4. Determine machine operator responsibility (also in regards to traffic regulations)
and allow him to refuse unsafe instructions from third persons.
5. Do not allow any person either still to be trained or already in training to
operate or work on machine unless under constant supervision and guidance
of an experienced instructor or operator.
6. Check and observe any person working or operating machine at least periodically
if they observe safety instructions and guidelines given in operator’s
manual.
7. Always wear proper work clothing when operating or working on machine.
Avoid wearing rings, watches, ties, scarves, open jackets, loose clothing, etc.
There is a danger of injury, as they can get stuck or be pulled in.
Prescribed for specific tasks: safety glasses, safety shoes, safety helmet, work
gloves, reflective vest, ear protection, …
8. Consult supervisor at jobsite for special safety instructions and regulations.
9. When entering and exiting the machine, maintain three-point contact.
10. When entering or exiting, never use joysticks as handholds.
This could trigger inadvertent movement of machine and cause serious accidents.
11. Never jump off the machine. When climbing on or off machine, use intended
steps, ladders and catwalks and handles. Use both hands for support and face
machine.
12. Keep steps, ladders and handles free of oil, grease, mud, snow and ice. These
precautions will minimize the danger of slipping, stumbling or falling.
13. Make yourself familiar with emergency exit.
14. If no other instructions are given, proceed as follows for maintenance and
repair work.
Procedure:
• Park the machine on solid and level ground. .1l
• Bring all control levers to neutral position. SJ
• Switch parking switch to park position. ~ 01
• Turn engine off and pull ignition key. ;;;
• Actuate control levers several times to relieve pressure in servo lines. i..,,
• Bring all control levers to neutral position.
15. Before working on hydraulic circuit, with engine turned off and with ignition key I~ii
in contact position, move all pilot controls uoysticks and pedals) in both direc- ~
tions to relieve servo pressure and remaining back pressures in working ~
circuits. Then release internal hydraulic tank pressure. ~
16. Before leaving operator’s seat, switch parking switch to Park position. ‘”‘
17. Secure all loose parts on machine.
18. Never operate a machine without a complete walk around inspection. Check if
all warning signs are on the machine and if they are all legible.
19. Observe all signs with danger and safety instructions.
