• Do not make any structural changes to the roll-over protection.
• At the time of damage, please contact your KUBOTA dealer. (Do not repair!)
• Never operate the excavator without the roll-over protection.
With the use of a h ydraulic hamm er or another attach ment f or demolition work, wher e materia l (e.g. asp halt) is
removed and can uncontrollably sputter away, a gravel guard is recommended for protection.
For demolition (acc ording to EN 474- 1, Annex G) , e.g. tearing do wn walls, the cor responding protec tive equipment is required (e.g. gravel guard).
Emergency hammer
In case of an accident where the exc avator cab door and windows can not be opened, the operator can break the window
panes with the emergency hammer (1).
When breaking the wi ndow pane, close your eyes
and cover them with an arm.
Hazards coming from the hydraulic system
If hydraulic oil gets into the eyes, rinse them immediately with clear water and subsequently seek medical aid.
Do not allow hydraulic o il to contact the skin or clothi ng. Skin parts which m ay have come in contact with h y-
draulic oil mus t be washed with water and soap im mediately, if possible. Do t his thoroughly and repeatedly,
otherwise there is a risk of damage to the skin.
Immediately take off any clothes dirtied or soaked with hydraulic oil.
Persons who have inhaled hydraulic oil vapours (mist) should be taken to a doctor immediately.
If leaks have occ urr ed i n th e hydraulic system, the ex c ava tor may not be taken i nt o op erati on or , if i n o perat io n,
operation must cease at once.
25
Safety rules
Do not use the nak ed hand to search for leaks; always use a piece of wood or cardboard. Pro tective clothing
(eye protection and gloves) must be worn when seeking leaks.
Leaking hydraulic oi l must be bound imm ediately with an oi l binding agent. T he contaminate d oil binding ag ent
must be stored in suitable containers and in accordance with the valid regulations.
Fire protection
The excavator components and attachments (in parti cular the engine and the exhaust system)
reach high temperatures even at normal working conditions. An electric installation which is
damaged or not prop erly serv iced may lead to flasho vers and/or el ectric arcs . The follow ing Fire
Protection Guidelines may help you ensure the maintenance and efficiency of your equipment
and minimize fire hazards.
• Remove any acc umulated dirt adjacent to hot components, e.g. engine, m uffler, exhaust manifold/tubes ,
etc. If the mac hine is being used to full capac ity, the cleaning procedur e should be performed m ore frequently.
• Accumulated r esidues from plants an d trees, or any other flammable materials , should be removed f rom
the machine. This m ust be observed in particul ar in the proximity of the eng ine and the exhaust system ,
but also at the swivel frame, the track frame, and the boom.
• Check the condition and wear of all fuel lines an d hydraulic hoses. A ny defecti ve parts s hould be r eplaced
immediately in order to avoid leakage.
• Electric lines and connections m ust be checked r egularly for signs of damage. Dam aged components and
lines must be replac ed or repaired before start ing up the machine. All electric connections must be kept
clean and solid.
• Exhaust pipes and mufflers must be checked daily for leaks, damage and any loose or missing joints.
Leaking or damaged exh aust s ystem components must be rep laced or re paired b efore starting u p the machine.
• Always keep a multipurpos e fire extinguisher at or close to the m achine. Make yourself familiar with the
operation of the fire ex tin gu isher . In t he e ve nt of f ire in the e lec tric a l or hydraulic system , us e a CO
tinguisher to combat the fire.
• For attachin g a fire extinguisher (1) two threads (2) have been inserted i n the cab construction on the left
side behind the driver’s seat.
A fire extinguisher is not included in the basic
equipment of the machine.

Recovery, loading and transport
RECOVERY, LOADING AND TRANSPORT
Safety rules for recovery
• For recovery of the ex cavator , a to wing ve hicl e of at le ast the s am e weight c lass as the excav ator m ust be
used.
• A tow bar must be used f or the recovery. If a tow rope is used, an additional vehicle to slow down the
excavator mus t also be att ached. T he tow bar or to w r ope m ust be sui table f or t he rec over y of the excavator in respect of the towed load. Do not use damaged recovery aids.
• Do not step into the danger zone bet ween the vehicles during the recovery procedure. If a tow rope is
used, keep a distance of at least 1½ times the length of the rope.
• Use the towing eye on the track frame for the recovery.
• The above safety rules also apply if the excavator is used as the towing or recovery vehicle.
• Observe the admiss ible values for the towed load and the m aximum pressing load vertical do wn on the
towing eye during recovery, see "Specifications" (page 35).
