

Hydraulic variable speed transmission assures easy
handling.



Deadman device which when pressed or hit will
cause the travel lever to return to neutral position
bringing the machine to a stop.



Non-corrosive water tank for the sprinkler system with a
capacity of 6 gallons.



Simple dual-lever controls assure operator safety and
convenience.



Sight gauge for hydraulic oil tank.



Front -mounted auxiliary travel lever.



Four large rubber shock mounts minimize vibrations to the
engine and hydraulics.

FREQUENCY/SPEED

The vibrating roller maximum frequency is 3000 vpm (vibrations
per minute). The forward and reverse travel speed of the vibratory
roller is approximately 1.8 mph (3 km/hour).

ENGINE

The Mikasa MDR-9D Vibratory Roller is equipped with a Hatz

MDR-9D — GENERAL INFORMATION

CAUTION :

NEVER! stand under, or get onto the roller

while it is being lifted or moved.

Tipping (Rollovers)

NEVER! operate the roller on side slopes (Figure 5). The

possibility exist that the roller could tip over (roll over), thus
causing bodily harm even death and serious damage to the
equipment.

CAUTION :

ONLY! use steel ropes or chains that are

capable of lifting at least 1,940 lbs. (880 kg ).

CAUTION :

NEVER! use any other part of the roller for

lifting purposes. Use the lifting eye. Using other
parts of the roller for lifting will cause severe
damage to the roller,

OPERATING ON SLOPES

Special care must be taken when operating the roller on hills or
slopes. There exist the possibility of serious injury to the operator
and severe damage to the roller in the event of a roll over.
ALWAYS operate the roller up and down hills rater than from
side to side. For safe operation hillside slopes should not exceed
12 degree (21 % grade). See Figure 4 below.

In the event the roller does tip over, extreme care must be taken
to prevent damage to the engine. When the roller has been
tipped over, oil from the engine crankcase can flow into the
combustion chamber, which can severely damage the engine
the next time it is started.

IMMEDIATELY after a unit has tipped over upright the unit as
soon as possible to prevent oil from leaking into the combustion
chamber.

Figure 5. Recommended Slope

CAUTION :

To prevent damage to the engine after a
rollover, the unit must NOT be started. NEVER
start a unit after a rollover. CONTACT your
nearest authorized Multiquip dealer for
instructions or servicing.
