PAGE 16 — AR13D RIDE-ON TANDEM DRUM ROLLER — OPERATION & PARTS MANUAL — REV. #2 (09/15/11)
AR13D RIDE-ON ROLLER — GENERAL INFORMATION
The forward-reverse control lever operates the hydrostatic pump
which governs the roller speed and direction of travel. The speed
in which movement of this lever is made is directly related to the
amount of pressure that is applied to the travel lever in each
direction. Travel speed is infinitely variable from 0 to 4.8 mph.The
neutral position of this lever will cause the roller to stop.
Before operating the roller, make sure that personnel and
obstacles are free from the roller’s path.
Serious injury
or
even
death
can result!
The AR13D roller has been designed for asphalt application
and compaction of granular soils used in site preparation. Use
the machine only for the purpose intended and by experienced
personnel who understand this operating manual and all safety
decals. Typical applications for this roller are driveways, patch
work and road repairs. Standard features included with this roller
are articulated steering, double drum hydrostatic drive, front drum
vibration, high curb clearance and on board water capability.
POWER PLANT
The AR13D roller is powered by a Brigss & Stratton DM 850D,
liquid cooled, diesel engine rated at 23.6 hp @3,600 rpm. The
engine is of a lightweight design and is exceptionally well
balanced for low vibration.
HYDRAULIC SYSTEM
The Brigss & Stratton DM 850D diesel engine drives an axial
hydraulic, variable displacement pump which is manually
controlled via a cable control system. Pump flow is directed
through an aluminum block manifold which provides the control
for the 3 hydraulic motors.
The hydraulic drum drive system incorporates a parallel closed
loop configuration operating at a maximum pressure of 2,900
psi. In addition this hydraulic system offers a "
free wheel valve
"
which allows the roller to be towed in the event of an emergency.
COMPACTION SYSTEM
The compaction force is delivered by a 36-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.
Connected to the axial hydraulic pump is a gear pump that
provides power for the drum vibratory system and the articulating
steering system. Oil from this pump flows to the manifold control
valve block and then to a hydraulic motor which rotates the
eccentric weights inside a sealed housing containing oil to
lubricate the bearings.
A pushbutton switch located on top of the gearshift lever when
pressed activates a
hydraforce
valve that engages or disgages
the vibratory action. The drum's vibratory action generates 3,100
lbs. (1,406 Kg.) of centrifugal force at a frequency of 4,000 vpm
(vibrations per minute). If the vibration appears to be weak or
slow, allow the machine to warm-up thoroughly, and check the
hydraulic oil level. Add hydraulic oil if necessary.
The vibrator housing and drum are shock mounted to isolate the
engine compartment and operator from vibration.
HYDRAULIC OIL FILTER SYSTEM
The hydraulic system oil is filtered by a screen type filter located
in the reservoir filler neck, then doubled filtered within the system
first by a 40 micron mesh-type suction filter located in the tank
and the by a
Zinga
10 micron, cartridge style spin-on return line
filter.
ARTICULATED STEERING SYSTEM
Power for the articulated steering system, which uses a single
hydraulic cylinder is provided by the gear pump. This steering
system can produce an inside turning radius of 109 inches (2.77
meters).
SPRINKLER SYSTEM
A 40 gallon (152 liters) water tank with a gravity feed spray bar
is provided for wetting the roll for asphaltic pavement rolling.
The water system is fully adjustable from the operator’s position
by adjusting the two water valves. The front valve controls the
water supply to the front drum, and the rear valve controls water
to the rear drum.
Before starting an asphalt rolling job, be sure all spray bar holes
are clear of dirt or foreign matter and are working. 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.
LIFTING THE ROLLER
When lifting of the roller is required, attach a suitable
hook or shackle to the
lifting eye
of the roller. These
lifting points (4) are marked by a lifting hook decal. Make
sure the lifting device is capable of lifting 4,000 lbs. (1,814 Kg).
The roller nominally has an operating weight of 3,088 lbs (1,400
Kg.), but can be increased to 3,309 lbs (1,500 Kg.) by adding
water ballast to the rear drum.
