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
POWER PLANT
The AR13HA/HAR roller is powered by a Honda GX630,
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 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
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
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
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
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
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).
