1.12 Main Features

The RD15 incorporates the following innovative features:

• Drive on both drums.

• Vibration on both drums at a single amplitude and

frequency.

• Central steering joint.

• Hydrostatic series transmission.

• Hydraulic series powered vibration.

• Hydrostatic steering.

• Negative hydraulic brakes on both drums.

• Water sprinkler equipment on both drums.

• Lighting and electrical equipment to highway code

standard.

• Stainless steel water tank.

• Speeds from 0–4.4 mph (7.0 kph).

1.17 Driving Position

The driving position has a large, comfortable seat provid-

ing good visibility to both sides of the machine. The

steering wheel has a knob. The dashboard houses the

ignition key, an electric hour meter and the engine

warning lights. The forward-reverse, brake, and accel-

erator levers are ergonomically positioned.

1.13 Hydraulic Equipment

The hydrostatic drive of the transmission and vibrating

systems is protected by an oil cooler and filters. The

transmission filter has a “filter clogged” indicator (a

vacuum gauge) on the inlet side of the pump.

1.19 Electrical Equipment

The electrical system is powered by a 12 Volt, 100 Ah

battery. The vehicle is fitted with a complete set of road

and work lights.

1.15 Chassis

The chassis consists of two half-frames linked by a

central steering joint. The front half-frame carries the

engine and transmission equipment and one of the drive/

exciter drums. The rear half-frame carries the driving

controls, the water tank and a drive/exciter drum.

1.14 Engine

The machine has an air-cooled diesel engine with electric

starter. The engine powers the hydraulic pump for the

steering and exciter equipment and the hydraulic trans-

mission pump.

1.16 Steering

A hydraulic gear pump drives the ORBITROL steering

servo which is controlled by the steering wheel. The

steering servo feeds oil to the double-acting steering

cylinders. In the event of a drop or failure in the pressure

supplied by the hydraulic gear pump, the steering will

continue to operate because the ORBITROL servo unit

will also act as a pump.

Turning the steering wheel G to the left or to the right

causes a corresponding movement of the front half-

frame. The steering joint between the two half-frames

has been designed so that the tracks made by the front

and rear drums are identical on all turning circles.

1.18 Operator Presence System

The machine is fitted with a safety device which locks the

engine transmission when the driver stands up or leaves

the driver’s seat. The machine can therefore only be

driven when the driver is seated.

BB00158

1A-12

1A OPERATION RD15

1.20 Transmission

Both roller drums are driven. A variable displacement

pump and hydrostatic transmission drive the hydraulic

motors fitted to each drum. Forward and reverse travel

are selected using a forward-reverse lever located to the

side of the driver’s seat. In order to comply with safety

standards, the machine has a safety device which only

enables starting of the diesel engine when the forward-

reverse lever is in the neutral position.

FORWARD-REVERSE lever

Shift the lever F into “Forward” A or “Reverse” I according

to the direction of travel desired.

An increase or decrease in road speed is obtained by

moving the lever forwards or backwards; road speed

varies from “ZERO” to a permitted maximum of 4.4 mph

(7.0 kph) Road speed is the same in both “Forward” and

“Reverse”. If you wish to change direction of travel from

FORWARD to REVERSE or vice versa, move the lever

to the "N neutral” position, allow the vehicle to come to a

complete stop, then move the lever in the direction

desired. The lever runs in a slider which prevents any

sudden inversion of the lever. The end of this lever is also

fitted with a switch R for the exciter pump.

Note: The machine is equipped with an "operator pres-

ence system". This "system" permits the machine to

move only when the operator is seated in the driving

position. The machine's motion is suspended when the

operator rises from the driving position consequently

activating the negative brake.

To restart:

• sit down in the driving position

• place forward/reverse lever into neutral

• operate forward/reverse lever.

When negotiating gentle slopes, keep the engine at high

rpm's and the Forward/Reverse lever at the minimum

position.

Refer to section 1.30 Driving on slopes and uneven

terrain for gradient limits. Vehicle speed must also be

regulated in accordance with current ground conditions

and vehicle road holding ability.

CAUTION: This vehicle has a hydrostatic transmission

which means that the Forward/Reverse lever can also be

used as an engine brake. Shifting the lever to the neutral

position stops the vehicle.

BB00012

112233

1A-13

RD15 OPERATION 1A

1.21 Exciter System

The exciter is electrically controlled and operates on both

drums. The exciter is driven by a gear pump. The

hydraulic motor, fitted to one side of the rear drum, is

splined onto the shaft of an eccentric weight by a splined

coupling. A switch on the forward-reverse lever operates

the exciter. The vehicle chassis is isolated from vibra-

tions by a series of shockmounts.

Exciter ON/OFF switch

To start vibration, turn the switch R to position 1.

To stop vibration, turn the switch R to position 0.

CAUTION: Do not keep the vibration running when the

vehicle is to remain stationary for some time.

Keeping the exciter on for a prolonged period when the

machine is stationary may cause serious damage to the

exciter equipment.

BB00114

BB00817

1A-14

1A OPERATION RD15

1.22 Braking System

The machine is fitted with negative brakes. Negative

brakes are automatically applied when there is no hy-

draulic system pressure. Hydraulic system pressure falls

when the forward-reverse lever is moved to the “0”

(neutral position), when the diesel engine is switched off,

or when there is a fault in the hydraulic system.

Service brake: this hydrostatic brake is applied when the

forward-reverse lever is moved to its central “neutral”

position.

Safety and parking brake: there is a multi-disc mechani-

cal brake on the rear drum. The brake is controlled by a

pushbutton. In the event of a pressure failure in the

hydraulic braking circuit, the brakes automatically switch

to the “on” position.

The pushbutton H is hydraulic and operates the negative

brake of the hydraulic drive motor.

Position 1 - Brakes on

Position 2 - Brakes off

The “Brakes ON” warning light I comes on when the

lever H is in position “1”.

Note: Negative brakes are automatically applied when

there is no hydraulic system pressure. Hydraulic system

pressure falls when the diesel engine is switched off or

when there is a fault in the hydrostatic transmission.

CAUTION: Do not use the parking or emergency brakes

when the machine is moving. The parking or emergency

brakes can only be used when the machine is moving in

cases of extreme emergency, i.e. following failure of the

main braking system (moving the Forward/Reverse lever

to the neutral position) or on slopes.
