2.5 Precautions for Work
2.5.1 Compaction operation
■
Understand the intended purposes of the rollers
• This roller is developed and manufactured mainly for compacting soil. Working with
vibrations under excessive rolling compactions or using for crushing operations may cause
damages to this machine. Do not use for any other purposes than rolling compactions in
civil engineering works.
■
Do not operate the vibration on a hard location
• Do not work the vibration on a hard surface such as concrete pavement, as this can cause
the machine to jump and give abnormal shock load. Damage to shock isolators will result.
■
Change the direction of travel gently
• When changing the direction of travel during compaction, slowly shift the F-N-R lever.
■
Drive at a speed appropriate for the road surface conditions
• Drive slowly on uneven surfaces.
2.5.2 When going downhill
■
Use the F-N-R lever
• Run slowly going downhill. Do not use excessive speed. Avoid changing speed if possible
when going downhill. Start slowly and end slowly on steep downgrades.
■
Use the engine brake
• Go downhill by applying the engine brake along with the F-N-R lever operation.
WARNING
• When going uphill, run at low speed. Can not attempt to shift speeds during
travelling. The machine can slip down the slope.
• When going downhill, adjust the travel speed not to allow the engine speed to
exceed 2,500 rpm.
2.5.3 On a slope
■
Working on a sidehill
• Work in an uphill / downhill direction, and avoid working on sidehill with the machine
inclining sideways.
2. OPERATION

Vibration can be turned ON / OFF with the vibration switch
Ⓒ .
Select a suitable setting depending on a working site condition .
" " position : Vibration can be turned ON or OFF with the
switch located on the F-N-R lever. Pressing
this switch causes the vibration to start and
pressing it again to stop.
This vibration switch on the lever should be
used with the vibrator switch on the panel
placed at or position.
"
CONT
" position : When the vibrator switch is set to the " "
or " " position, you can perform vibration
work without turning the vibration switch ON
and OFF.
3) Proper travel speed for vibratory compaction is 2 – 5 km / h (1.2 – 3.1 mile / h) , however,
select speeds depending upon job requirements.
IMPORTANT
• Keep the vibrator shut off when the machine is not rolling.
• Stop vibration if the machine has encountered a running difficulty, for example,
when it gets stuck in the mud.
• Set the speed change switch in the position during vibratory rolling
compaction. Use the position only for driving on flat straight roads.
