OPERATING TIPS
Look down and to the rear and make sure area
is clear before operating in reverse.
Do not operate on steep slopes.
Do not stop, start, or change directions sud-
denly on slopes.
Use extreme care and reduce ground speed on
slopes and rough terrain.
Watch for hidden hazards on the terrain during
operation.
Before working underneath, read manual
instructions, securely block up, and check stability.
Secure blocking prevents equipment from drop-
ping due to hydraulic leak down, hydraulic system
failure, or mechanical component failure.
Stop power unit and equipment immediately
upon striking an obstruction. Turn off engine,
remove key, inspect, and repair any damage before
resuming operation.
BACKFILLING
For backfilling ditches or trenches, reverse the blade by
rotating counter-clockwise and back push.
LEVELING AND GRADING
Set the blade to the desired position of offset, angle
and tilt for leveling and grading.
