PAGE 18 —V304 VIBRATORY ROLLER — OPERATION AND PARTS MANUAL — REV. #8 (11/13/09)
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
marring
. A fully
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.
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).
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
lifting eye
of the roller. Make sure the
lifting device is capable of lifting 1,045 lbs (450 kg).
