SAFE OPERATION-6
13.To avoid fire, do not heat the hydraulic components
(tanks, pipes, hoses, cylinders) before they have been
drained and washed.
14.Use eye protection or a face mask to protect the eyes
and respiratory system against dust and other foreign
particles.
15.Securely support excavator with stands or suitable
blocking before working underneath. For your safety,
do not work under any hydraulically supported
devices. They can settle, suddenly leak down, or be
accidentally lowered.
16.Do not dismantle the spring of the track tensioner. If
dismantling is necessary, contact your KUBOTA
dealer where the machine was purchased, or
competent service shop. The assembly must be done
according to the KUBOTA work shop manual (W.S.M.)
for the product involved.
17.When lifting the machine itself with an attachment,
place a safety block or safety post to prevent the
machine from rolling over. Keep the lock lever for
attachment control in the "LOCK" position.
18.Inspect ROPS / FOPS for damage and if damage is
found contact your KUBOTA dealer for repair.
19.KUBOTA does not use asbestos containing
components and recommends against the use of such
components.
Components containing asbestos should be handled
in accordance with applicable regulations and industry
practice.
20.Fire prevention
Excavator and some attachments have components
that are at high temperatures under normal operating
conditions. The primary source of high temperatures is
the engine and exhaust system. The electrical system,
if damaged or incorrectly maintained, can be a source
of arcing or sparks.
The following fire prevention guidelines will help to
keep your equipment up and running efficiently and
keep the risk of fire to a minimum.
A Blow off all accumulated debris near hot engine
exhaust components such as turbocharger and
exhaust manifold as well as exhaust pipes and muffler
more frequently when working in severe conditions.
A Clean out all accumulated flammable debris such as
leaves, straw, pine needles, branches, bark, small
wood chips and any other combustible materials from
inside the machine belly pans or lower unit structures
as well as from area in proximity to the engine.
A Inspect all fuel lines and hydraulic hoses for wear or for
deterioration. Replace them immediately if they begin
to leak.
A Examine electrical wiring and connectors frequently
for damage. Repair any wires that are loose or frayed
before operating the machine. Clean all electrical
connections and tighten all electrical connections as
necessary.
A Inspect the exhaust system daily for any signs of
leakage. Check for broken pipes and muffler and also
for loose or missing bolts, nuts and clamps. If any
exhaust leaks or fractured parts are found, repairs
must be completed prior to operation.
A Always keep a multipurpose fire extinguisher on or
near the machine. Be familiar with the operation of the
fire extinguisher.
