we're here to let joe shafen show us how
to do a pre-op on a dozer
by the way i do a pre-op check i start
on the ground
now i start looking for cracks loose
bolts
we broke pins and the jacks hydraulic
leaks on the jacks
steps make sure all the steps are
together and ain't broke
and i'll come back and just keep looking
get down
i've checked the roller caps make sure
the bolts are in it
and push arms
make sure all the boats are in the final
drive
just keep on looking hook up
come back here make sure everything's
tight
i'll take a look underneath the dozer
make sure there ain't no boats that i
can see that's missing
and or any hydraulic lakes
looks pretty good
do the same thing on this side check for
loose bolts cracks
make sure your spark bolts are tight
steps on this side make sure they're
still ain't got no cracks in them
your hand rails
check your pins in your blade it's gonna
make no cracks or anything
except for cracks in your blade your
corner bits make sure you got no corner
boats missing
cutting these boats
everything looks pretty good
then i go up in the dozer i check the
engine hole

check your transmission
transmissions got plenty old
kind of i look at your far suppression
make sure your hoses are tight and
nothing seems loose on it
let's get the cab i'll check my front
horn

you also need check your lights and your
wipers too
yeah everything looked good i feel like
my pre-shift book
get tires up
write yours down what job you're on
what shift you work equipment number
what type the date
and check off everything you looked at
and if you didn't see no
nothing needs looked at just check it
off
but if you see like a missing bold or
something like that you just
write down needs repaired
if it's something that needs attention
right then this holler at your
supervisor and
he'll get you a mechanic
brakes and lights should also be checked
before beginning work
have a co-worker make sure your lights
are working and
test your brakes before moving to the
active mine site
and remember to check these things
before getting your day started
cab air filters door seals the air
conditioning and heating system
the turbo oil line and your fire
suppression system
