CHAPTER 4 – OPERATING INSTRUCTIONS
4-7
OPERATION
This machine and its attachments are to be operated only
by a qualied operator stationed at the operator’s controls
either seated or standing as conditions require.
The use of the seat belt is recommended always, even on
the machines equipped with ROPS.
Before starting the machine, check, adjust and lock the
operator’s seat assembly for maximum comfort and con-
trol of the machine.
This machine is equipped with power steering which is
effective only when the engine is running. If engine fails,
stop the machine immediately.
For emergency stops, apply foot brakes as required or
pull parking / emergency brake lever.
Check the torque of the wheel bolts after every 20 hours
of operation until the wheel bolts stay tight, if the machine
is new or if a wheel has been removed and installed. Ti-
ghten according to procedure and specications manual
instructions.
Always travel with the scarier in the full raised position
and lower to the ground when parked.
Use extra care when using down pressure on the blade
when working on hills, banks and slopes.
NOTE: When the Grader wheels have been turned to the
maximum (in either direction), do not continue to turn the
steering wheel in the same direction. This causes unne-
cessary wear on pump and valve components of steering
system.
To start machine motion, raise moldboard, release parking
brake, shift into the desired range and direction and move
the throttle lever to meet the operational requirements.
Select a transmission range that will maintain engine spe-
ed appropriate for the load required. Low engine speed
can be corrected by downshifting or lightening the load.
Over revving the engine should be avoided.
Slow the machine by applying the brakes.
Incorrect gearshift can result in an accident for the ope-
rator as well as damages to the machine and the trans-
mission.
Observe the following instructions:
Down shift only when the ground speed for the se-1.
lected range has been achieved.
Down shift only one range at a time.2.
WARNING: Do not coast the machine at any
time with the transmission in neutral. Do not at-
tempt to decelerate on grades by shifting. De-
celerate the engine and apply the foot brakes.
Anticipate grades before starting down.
CAUTION: Select the proper gear range to
maintain the control. Engage transmission to
start up only when the engine is at low idle.
Down or up shift only one range at a time and
only when the speed of the machine approxi-
mates the speed of the next range.
The transmission range and engine speed should be set
before beginning the grading operation. Never overload
the moldboard, so that the rear wheels begin to slip. This
not only alters the grade but causes unnecessary wear
to rear tires.
Increasing the blade angle (putting one blade tip farther
forward than the other tip) will reduce the load. The blade
should be set to cast the dirt either inside or outside of the
rear wheels, not under the wheels unless it is for compac-
tion purposes.
The moldboard pitch can be changed to suit various ope-
rations. When the top of the moldboard is tilted forward
the cutting edge will not slice the material, but push it.
This is advantageous when pushing dirt from one location
to another. Tilting the top of the moldboard to the rear will
angle the cutting edge so that it will slice and create a bite
into the material. This can be advantageous in heavy ma-
terial because the material will roll against the moldboard,
breaking it up and making it easier to move.
Using the moldboard to back drag material should be
avoided if possible. This can cause heavy wear on the
moldboard guides and possibly damage the side shift
cylinder piston rod. If back dragging cannot be avoided,
make certain material does not contact the positioning
piston rod.
Worn or poorly adjusted moldboard guides will cause an
unstable moldboard for ne grading.
When making heavy cuts or moving heavy loads that tend
to side shift the Grader, lean the front wheels toward the
load to counteract side shift.
