Item 5.

perator, you just started your dozer
and you’re ready to move out.
..right?
Not so fast!
Your dozer is like an athlete who
needs to warm up before the race and
cool down afterward. If it doesn’t warm
up and cool down—just like an ath-
lete—major moving parts can break
down. Then the dozer will be sitting
instead of working.
Here’s what you can do to keep your
dozer on the job:
Warm It Up
Immediately after start-up, make sure
you have engine oil pressure. Then run
the engine at 700–800 rpm for 5 min-
utes or so to warm up.
That gives the oil time to lubricate
the parts. It also lets the engine warm
up enough to boil off condensation
caused by normal engine breathing.
That way, you won’t have to worry
about condensation mixing with the

Gauges within normal range?
Cool Down, Too
After you’ve run that dozer hard, let
it cool down before shutting it off. Idle
the engine for 5 minutes. The engine
needs to cool down slowly, or the heat
can crack the block, warp a head or
valves, or bake the oil until it’s not
slick enough to lube the bearings.
oil and forming a sludge that’ll clog
the engine.
Once you’ve got the dozer warmed
up and operating, check the gauges,
especially those for water temperature
and engine oil pressure. They should
be within the normal operating range.

perators, while the SEE’s backhoe is in the transport position, it’s a bear to
get at tools stowed in the small toolbox behind the cab.
To keep those tools handy, move ’em to the tool chest used for the chain saw
and hydraulic tool accessories. Keep the vehicle’s jack in place by using the
tiedown straps in the tool chest.
