AR13HA-R RIDE-ON ROLLER — GENERAL INFORMATION
The AR-13H 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 AR-13H roller is powered by a Honda GX-610, air cooled,
gasoline engine rated at 18 hp @3,500 rpm. The engine features
a side-mounted muffler designed to direct engine exhaust away
from the operator. In the event of low oil, this engine has a built in
oil alert system
"
reaches an unsafe operating level.
HYDRAULIC SYSTEM
The Honda GX-610 engine drives an axial hydraulics, 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 "
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
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
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.

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.
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
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 60 gallon (227 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 points (4) are marked by a lifting hook decal. Make
sure the lifting device is capable of lifting 4,000 lbs. (1,814 Kg).

obstacles are free from the roller’s path.

CAUTION - Lifting the Roller
When lifting of the roller is required, only use the provided

to lift the roller. Using other sections of the roller
for lifting purposes may 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.

In the event the roller does tip over, if at all possible, try to shut-
OFF
down the engine by turning the ignition key to the
position.
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.
CAUTION - Roller Rollover Safety
To prevent damage to the engine after a rollover, the roller
must NOT be started. NEVER start a roller after a rollover.
CONTACT your nearest authorized multiquip dealer for
instructions or servicing.

Hydraulic Oil System
The hydraulic system consists of a two pump stack directly
coupled to the engine. A hydraulic valve block (manifold)is
provided for quick and easy testing and troubleshooting.
Hydraulic oil is filtered by a screen filter located in the tank filler
neck, a
micron return filter
40 micron suction filter
located in the tank, and a
, with cold oil bypass valve located in the

important part of proper hydraulic system operation. Hydraulic
oil is not only used to transfer power; it also lubricates and cools
the system components. Keeping the hydraulic system clean
can help reduce costly repairs.
The hydraulic oil level sight glass is located on the right rear of
the front drum, below the engine compartment. This level should
be checked daily. Oil must be below the top and above the bottom
of the sight glass. DO NOT OVERFILL! Care should be taken to
clean the filler cap before adding oil to the system. If hydraulic oil
has to be added, the machine should be inspected for leaks.

Forward/Reverse Hydraulic Pressure Test
Park the machine on a solid flat surface and stop the engine. Set
the parking brake and
1. Check hydraulic oil level by viewing the hydraulic oil sight
glass. The hydraulic oil level must be below the top and
above the bottom of the sight glass. DO NOT OVERFILL!
2. Adjust engine RPM (3,500 +/- 50 RPM)
3. Let engine run for 5 minutes, this will bring the hydraulic oil
operating temperature to a minimum of 135
4. Check and repair all hydraulic leaks.
5. On the manifold block install a 5,000 psi pressure gauge
(Figure 34) to the
test port 2
6. Run engine at full throttle.
7. Move the

9. Return the travel lever to the
engine.
10. Install the pressure gauge into the reverse quick disconnect
port 3
and repeat the above procedures. The relief pressure
reading for the reverse test port 3 will be the same (2,900
psi). Again normal operation pressure for the reverse port
will be 400-600 psi.
Normal operating pressures are based on the machine
traveling on level, firm surface. The operating pressures
will increase significantly when traveling uphill.

reading for the steering test port 1 will be 700 psi. Again,
under normal operating conditions, pressure for the
steering port will be between 200-400 psi.
If maximum pressure cannot be reached, plug the steering
cylinder pressure hoses and re-test. If pressure is correct the
steering cylinder is leaking. DO NOT ACTIVATE THE
