MDR-9D — OPERATION
VIBRATING
1. Shift the two vibrator levers (Figures 21 and 22) to the
vibrate position to start vibrations.
Using vibration with clutch slipping
causes the clutch to burn. Also, vibration
should NOT be used over completely
compacted area, paved road surface, or
with stationary roller.
CAUTION :
WATERING
1. To operate water sprinkling system, turn on the front and
rear water valves on the side of the roller. (Figure 23).

STOPPING
1. Place the vibrator and travel levers to the neutral position.
2. Slow down the engine and allow to cool for at least 2
minutes. Place
speed control lever
in the stop position
and listen for the engine to stop running.
3. The hydraulic brake is automatically engaged when the
travel lever is in neutral position. When parked on a slope
with the engine turned off, place a block against the
roller drum to prevent the roller from moving.
CAUTION :
NEVER attempt to stop the engine by
moving the decompression lever. Always
use the speed control lever to stop engine.
UNLOADING
1. If you need to move the roller by pushing it manually
once engine is stopped, push in the upper and lower
knobs of the transmission check valve. This will
cause the hydraulic break to disengage and allow
the roller to be moved without causing
damage(Figure 24).
2. After moving, reset upper and lower knobs.
NEVER tow roller with any type of vehicle.
Doing so will damage the hydraulic
system.
NEVER perform unloading procedure on
a slope. This may cause roller to roll down
if parking brake or blocking is deficient.
