NOTES
AR14H RIDE-ON ROLLER • OPERATION MANUAL — REV. #3 (09/06/19) — PAGE 11
GENERAL INFORMATION
The AR14H roller has been designed for asphalt application
and compaction of granular soils used in site preparation.
Machine should only be used for the purpose intended and
by experienced personnel who understand this operation
manual and all safety decals. Typical applications for this
roller are compaction of base material, asphalt patching
and roadway construction.
Standard features included with this roller are compact
design, recessed drive motors,maintenance-free articulation
joint and vibrator assembly, easy-to-use controls, 34-gallon
(130 liters) water tank, and hour/tachometer.
POWER PLANT
The AR14H roller is powered by a Honda GX630, aircooled, gasoline engine rated at 20.8 hp @3,600 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.
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 grease to lubricate the bearings.
A toggle switch located on the side of the travel lever,
activates a valve that engages or disengages the vibratory
action. The drum's vibratory action generates 3,400 lbf
(15.1 kN) of centrifugal force at a frequency of 4,200 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 2,688 lb.
(1,219 Kg) but can be increased to 2,980 lb. (1,352 Kg) by
adding a water ballast to the rear drum.
HYDRAULIC OIL FILTER SYSTEM
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.
The hydraulic drum drive system incorporates a series
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.
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.
COMPACTION 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 150 inches (3.81 meters).
SPRINKLER SYSTEM
A 34-gallon (130 liters) water tank, with a pressurized
feed spray bar, is provided for wetting the roller for asphalt
pavement rolling.
The water system is fully adjustable from the operator’s
position with a single volume control.
LIFTING THE ROLLER
The compaction force is delivered by a 35.6-inch wide steel
drum with beveled edges to help prevent asphalt marring.
A fully enclosed hydraulic drive system offers a variable
speed control as well as smooth acceleration and braking.
PAGE 12 — AR14H RIDE-ON ROLLER • OPERATION MANUAL — REV. #3 (09/06/19)
When lifting of the roller is required, attach a
suitable hook or shackle to the lifting eyes 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 lb. (1,814 Kg).
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.
CAUTION
ONLY use approved certified lifting devices capable of
lifting at least 4,000 lb. (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.
OPERATING ON SLOPES
Special care must be taken when operating the roller on
hills or slopes. There exists 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
rather than from side to side. For safe operation, hillside
slopes should not exceed 14 degree (25 % grade). See
Figure 2. Always wear seat belt when operating the roller.
IMPROPER OPERATION ON SLOPES
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.
SIDE TO SIDE
OPERATION
NOT
RECOMMENDED
ROLL OVER
Figure 3. Improper Operation on 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. Clean oil 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.
2. Remove the hydraulic oil drain plug (Figure 28) and
drain the hydraulic oil. Dispose of the used oil in an
environmentally friendly manner. Replace the drain
plug and tighten.

The return filter (Figure 28) 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
can penetrate the skin, blind, cause burns or create
other potentially dangerous hazards follow all safety
instructions as described throughout this manual.
CHANGING HYDRAULIC OIL AND FILTERS
1. Park the roller on a clean flat work area and set the
parking brake.
3. Remove the return filter and install a new filter. Dispose
of the used filter in an environmentally friendly manner.
4. Disconnect the suction hose and remove the fitting from
the tank. Replace the suction filter. Dispose of the used
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.
This hydraulic system has a freewheel engagement valve
allowing hydraulic oil to be bypassed. Open (turn allen
wrench counterclockwise) this valve (Figure 29) 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.

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
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 toggle switch mounted on 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 switch is in the “OFF” position, this valve is open
allowing oil to go to the steering valve, without driving the
vibration motor.
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.
The drum drive circuit is a series, 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 travel lever located on
the right side of the operator seat. When the travel 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.
With the travel lever in reverse position, oil will flow in the
opposite direction (port B becomes high-pressure and port
A becomes suction).

MAINTENANCE
ALTERNATOR/REGULATOR
This roller is equipped with a 20-amp charging system. This
system uses three charge coils connected in parallel. The
windings of each coil are wound with heavy-duty insulated
wire and are further protected by insulating material for long
life. A voltage regulator is provided to control the amount
of charge voltage being delivered to the 12 volt electrical
system. For servicing this charging system, contact your
Honda dealer.
NEUTRAL SAFETY SWITCH
The travel lever is provided with a neutral safety switch
(Figure 37) that prevents the engine from starting when
the lever is in the forward or reverse drive position. Lever
must be placed in the neutral position in order for the starter
to function.
TRAVEL LEVER
To test the vibration solenoid, turn the ignition switch on.
Check for proper supply voltage and ground. If proper
voltage and ground are present, check the solenoid for
continuity. If no continuity, replace the solenoid coil. If
continuity is present, place your hand on the solenoid and
turn the switch to the ON position; movement should be felt.
DO NOT START THE ENGINE FOR THIS TEST.
Figure 38. Vibration Solenoid
BATTERY
Mishandling of the battery shortens the service life of the
battery and adds to maintenance cost. When handling the
battery do the following:
NEUTRAL SAFETY
SWITCH
WHITE
GREEN
Figure 37. Safety Switch
To check this switch, remove the panel located below and
to the rear of the floor. This switch is mounted to the lower
forward/ reverse lever mechanism. Disconnect the white
and green wires. Place the lever in neutral and test for
continuity. Place the lever in forward or reverse; no continuity
should be present. Repair or replace as required.
VIBRATOR SOLENOID
The vibrator solenoid (Figure 38) is located in the manifold
valve block and is controlled by the vibration switch located
on top of the travel lever. This solenoid controls the vibration
control valve which supplies hydraulic oil to the vibration
drive motor.
Be careful not to let the battery electrolyte come in
contact with your body or clothing.
Always wear eye protection and rubber gloves, since
the battery contains sulfuric acid which burns skin and
eats through clothing.
Check the battery regularly and make sure that each
electrolyte level is to the bottom of the vent well
(Figure 42). If necessary, add only distilled water in a
well-ventilated area.

PREPARATION FOR LONG-TERM STORAGE
ROLLER STORAGE
For storage of the roller for over 30 days, the following is
recommended:
1. Drain the fuel tank completely, or add STA-BIL to the
fuel.
2. Run the engine until the fuel in the injection system is
completely consumed.
3. Completely drain used oil from the engine crankcase
and fill with fresh clean oil, then follow the procedures
described in the engine manual for engine storage.
4. Drain water tank.
5. Clean the entire roller and engine compartment.
6. Remove battery and store it in cool dry place.
7. Cover the roller and place it a clean dry area, that is
protected from harsh elements.
8. Remove ignition key, and store in a safe place.
