not allow the blade corner to dig, since this steepens the

In finishing
side slopes
by working diagonally, start the dozer at the bottom and
work diagonally
up the slope (fig. 11-37). A windrow

formed and is continually
drifted to one side, tending to
fill low spots or irregularities.
l Navy safety regulations
require that all dozers be
equipped
with

strictures
(ROPS),
crankcase guards, and radiator
protectors.
All dozers
purchased by the Navy are equipped with these devices.
Dozers must never be used without

Push
Dozer
The push dozer in figure 11-38 is equipped with
a
push blade. However,
in most cases, a straight-blade
dozer that has a reinforced
block in the center of the
blade is used. Ensure the center lines of the pusher and
scraper are aligned. If alignment
is not centered, it is
hard to keep the pusher straight

Dozer
Safety
l Operators
of dozers and rippers
should
make
every effort to learn the locations of any underground
high-voltage
electric lines or gas lines that might be
contacted by their equipment.
Standard
safety precautions
that apply to dozer
operations
are as follows:
l Operate the dozer from the sitting position, never
from a standing position.
l Only operate the dozer at speeds at which control
of the dozer can be maintained
at all times.
l A dozer must be operated
with
extreme
care
when near the edge of a cut; the edge may give way,
overturning
the machine.
l
A steep incline
should
be climbed
slowly.
Gunning up a steep slope has often caused dozers to
overturn.
