AR13HA-R RIDE-ON ROLLER — 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.

The return filter (Figure 26) is located at the front of the engine compartment. Replace both filters according to the Table 5.

CAUTION - HYDRAULIC SYSTEM HAZARD

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.

2.Remove the hydraulic oil drain plug (Figure 26) and drain the hydraulic oil. Dispose of the used oil in an environmentally friendly manner. Replace the drain plug and tighten.

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

This hydraulic system has a freewheel engagemet 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.

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.
