GENERAL INFORMATION
The AR13HA/HAR 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 operation 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 AR13HA/HAR roller is powered by a Honda GX630,
air-cooled, gasoline engine rated at 20 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" that
will shut down if the engine oil level reaches an unsafe
operating level.
HYDRAULIC SYSTEM
The Honda GX630 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.
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 a 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 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
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 disengages the vibratory action. The drum's vibratory
A 40-gallon (181 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 four lifting points are marked by a
lifting hook decal. Make sure the lifting device
is capable of lifting 4,000 lbs. (1,814 Kg).
PAGE 12 — AR13HA/AR13HAR ROLLER (S/N 110301 & UP) • OPERATION AND PARTS MANUAL — REV. #0 (06/22/11)
GENERAL INFORMATION
DANGER
DO NOT allow personnel to stand under or near any
suspended machine. Before operating the roller, make
sure that personnel and obstacles are free from the
roller’s path. Serious injury or death may result.
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.
CAUTION
ONLY use approved certified lifting devices capable of
lifting at least 4,000 lbs. (1,814 Kg.).
CAUTION
When lifting of the roller is required, only use the
provided lifting eyes to lift the roller. Using other sections
of the roller for lifting purposes may cause severe
damage to the roller.
TIPPING (ROLLOVERS)
CAUTION
NEVER operate the roller on side slopes (Figure 3). The
possibility exists that the roller could tip over (roll over), thus
causing bodily harm, even death, and serious damage to
the equipment.

Figure 3. Tipping (Rollover)
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 (27 % grade). See Figure 2.
MAXIMUM SLOPE
27%
Figure 2. Recommended Slope
In the event the roller does tip over, if at all possible, try to
shut down the engine by turning the ignition key to the OFF
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.
NOTICE
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.

MAINTENANCE
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 40 micron suction filter located in the tank, and
a 10 micron return filter, with cold oil bypass valve located
in the return circuit.
It is recommended that ISO 46 type hydraulic oil or
equivalent be used when adding or replacing the hydraulic
oil is required.
DO NOT USE MULTI-VISCOSITY OIL. Cleanliness is a
very 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.
The suction filter (Figure 26) is located inside the hydraulic
tank. This filter is attached to the fitting connected to the
hydraulic pump suction hose.

filter in an environmentally friendly manner. Replace
the fitting and reconnect the suction hose.
FREEWHEEL ENGAGEMENT VALVE
NOTICE
The freewheel engagement valve (towing) is only for
emergency use. DO NOT move roller over 2 MPH or
long distances as hydraulic system component failure
could result..
The return filter (Figure 26) is located at the front of the
engine compartment. Replace both filters according to the
Table 5.
CAUTION
DO NOT open hydraulic lines or loosen hydraulic fittings
while engine is running! Hydraulic fluid under pressure
This hydraulic system has a freewheel engagement valve
allowing hydraulic oil to be bypassed. Open (turn allen
wrench counter-clockwise) this valve (Figure 27) to engage
the freewheel capability of the roller. When the valve is fully
opened, ports A and B are allowed to connect, bypassing
the oil to and from the drum drive motors.

Figure 27. Freewheel Engagement Valve
MAINTENANCE
Remember the freewheel engagement valve should only
be used in emergencies when the roller cannot be driven
due to engine or hydraulic system problems.
When towing of the roller has been completed, this
valve must be closed (turn allen wrench fully clockwise)
completely and the lock nut set. Failure to close this valve
completely will result in low power, improper speed, and
excessive hydraulic oil temperature.
DRUM DRIVE
The drum drive circuit is a parallel, closed loop system
consisting of a hydrostatic pump, two relief valves, a
freewheel engagement valve, and front and rear drum
drive motors.
The hydrostatic pump is manually controlled by a cable
connected to the forward/reverse shift lever located on the
right side of the operator seat. When the shift lever is placed
in forward, high-pressure oil is supplied by the hydrostatic
pump to the valve block (port A). The valve block (manifold)
directs this high-pressure oil to the front and rear drum
drive motors. Return oil from the motors is returned to the
valve block (port B) and is returned to the suction side of
the hydrostatic pump.
When the switch is in the “ON” position, the electric control
valve closes and oil is directed out of port 1 to the vibration
motor. Return oil from the motor returns to the valve block
via port 2 and is directed to the steering valve.
Steering is controlled by a steering valve and cylinder.
The steering wheel is direct coupled to the steering valve
controlling the oil flow to the cylinder. Oil supplied from the
vibration circuit is directed to port 3 which connects to port
P of the steering valve. When steering is not being used,
oil passes out of port T of the valve block and returns to
the hydraulic tank. When the steering wheel is operated,
the steering valve closes and oil is directed to ports L or R
to extend or retract the steering cylinder.
RUBBER SCRAPPER MAT
Rubber scraper mats have been provided for the cleaning
of the front and rear drums. Adjust the scrapers mats as
close as possible to the drums, using the slotted holes
(Figure 28) provided. Replace these rubber mats when
they become badly worn.
When shifted into reverse, the high-pressure and suction
ports on the hydrostatic pump are reversed. Oil flow is
then in the opposite direction of forward (port B becomes
high-pressure and port A becomes suction).
VIBRATION AND STEERING
The vibration and steering system is an open loop circuit
operated by a gear type pump. Separate relief valves control
each circuit. This system consist of the gear pump, relief
valves, electric vibration control valve, vibration drive motor,
steering valve, and steering cylinder.
The vibration circuit is controlled by an electric control
valve located on the valve block (manifold). This valve is
controlled by the “ON/OFF” pushbutton switch mounted on
top of the travel lever.
High-pressure oil is supplied by the pump to the valve block
(port P) and is directed to the electric control valve. When
the pushbutton switch is in the “OFF” position, this valve is
open allowing oil to go to the steering valve, without driving
the vibration motor.
