with a damaged air filter, or a filter in need of
replacement will allow dirt to enter the
engine, causing rapid engine wear.

WARNING

Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas

V304 — GENERAL INFORMATION

The V304 Vibratory Roller is a walk-behind vibratory roller
specifically designed for the compaction and patching of asphalt
type surfaces.

The compaction force is delivered by a 30-inch wide steel drum
with beveled edges to help prevent asphalt
enclosed hydrostatic drive system offers a variable speed control
as well as smooth acceleration and braking

HYDROSTATIC DRIVE SYSTEM

This hydrostatic design offers a smooth performance, because
of a fully integrated hydrostatically actuated drive system, which
provides a variable speed control under varying load conditions.
Power from the hydraulic drive system is transferred via a drive
belt to a gear reducer.

CONTROLS

The forward-reverse control lever (located on the handle)
operates the hydrostatic pump which governs the roller speed
and direction of travel. The neutral position of this lever will cause
the roller to stop. The vibration control when actuated will apply
a force of 4,400 vpm (vibrations per minute). This vibratory feature
is controlled by an eccentric shaft via an operator controlled
mechanical clutch.

SPRINKLER SYSTEM

A 8.3 gallon (31.4 liters) water tank with a gravity feed spray bar
is provided for wetting the roll for asphaltic pavement rolling.

Before starting an asphalt rolling job, be sure all spray bar holes
are clear of dirt or foreign matter and are working. A coco mat is
provided to insure an even distribution of water.

DO NOT leave the coco mat in contact with the roll (drum) when
the roller is used for earth compaction. A hook is provided to hold
the mat away from the roll. The coco mats are intended to prevent
the build-up of material between the drum and the frame.

Always use clean fresh water in the water tank. To prevent rust
and foreign debris from clogging the spray bar holes, drain and
flush water tank and spray bars every 30 days.

TRANSPORTATION

To help transport the roller from job site to job site, adjustable
transport hooks have been provided. These transport hooks allow
an operator to place the roller on the tailgate of a dump truck
without any assistance. The control handle of the V304 roller
can be folded vertically for ease of transport and storage.

LIFTING THE ROLLER

When lifting of the roller is required (Figure 7), attach a suitable
hook or shackle to the

of the roller. Make sure the

FREE WHEEL ENGAGEMENT LEVER

The hydrostatic transmission is equipped with a free wheel
engagement lever, which, when actuated, allows the oil to circulate
freely within the roller, thereby permitting the roller to be moved
without the engine running. This lever is only to be used in the
event the roller is disabled.

This lever is located on the that side of the transmission which
faces the front of the roller. It is actuated by placing the handle
into the side-lock position. To gain access to this lever raise the
roller's hood. DO NOT raise hood while engine is running, STOP
engine.

NOTE

.

In normal operating conditions the roller
will not move in a forward or reverse
direction unless the free wheel
engagement lever is in the engage position
(forward).

V304 — GENERAL INFORMATION

CAUTION :

while it is being lifted or moved.

CAUTION :

ONLY! use steel ropes or chains that are

capable of lifting at least 1,045 lbs (450 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,

NEVER! stand under, or get onto the roller

Tipping (Rollovers)

NEVER! operate the roller on side slopes (Figure 9). The

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

Figure 9. Tipping (Rollover)

In the event the roller does tip over, extreme care must be taken

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 8 below.

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.

CAUTION :

Figure 8. Recommend Slope

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.
