1.10 Application

This machine is designed for compaction of sub-bases and backfill for foundations, roads, parking lots, etc. A selection

of drum types, drum size, and two vibration modes ensures excellent compaction of cohesive-type soils, as well as

loose soils and gravel. The drums protrude past the machine frame, making it ideally suited for working along trench

walls, excavations, pipelines and backfill applications.

1.11 Remote Control Features

This machine is designed specifically for remote control

operation. This feature protects the operator by keeping

him or her a safe distance away from the machine, and

the work area, during operation. When used in excava-

tions, it allows the operator to stand safely above the

trench, rather than in it.

The machine can be operated using either the standard

cable operated control system (a), or through an optional

wireless infra-red remote control system (b).

A built-in override detects if both control systems

are on at the same time. The override will automati-

cally disable the infra-red control system, if it detects

that the cable-operated control system is on.

The cable-operated control system uses a power cord to

connect the control box to the machine. By adding the

optional wireless infra-red control system, operating range

can be extended to 65 ft. (20 m).

Each system provides operator control of the following

machine functions:

1 - Forward ................................. F

2 - Reverse .................................R

3 - Vibration-High ......................

4 - Vibration-Low........................

5 - Steering-Left .......................... L

1.13 Starting

1. Check that the vibration switch on the control box (f)

is centered in the “0” (off) position and that on-off

switch (g) is in the “0” (off) position.

2. Pull throttle control

in position by rotating handle clockwise, until tight.

3. Turn key switch

(e) on machine to the ON position. Set

on-off switch (g) on control box to the “I” (on) position.

Press in engine start button

(h) and hold it down until

engine starts. Leave the key switch and on-off switch

on while operating roller.

CAUTION: DO NOT crank the engine more than 15-

20 seconds at a time or starter motor may overheat.

Wait 30-45 seconds between start-up attempts so

starter motor can cool down.

To operate machine using infra-red remote control,

the on-off switch (g) on the cable-operated control

box must be set to the “0” (off) position, or cable control

box must be disconnected from machine.

See Unit 2, “INFRA-RED CONTROL”, for more

information on the infra-red operating system.

4. Allow engine to warm up for a few minutes before

operating machine.

The yellow indicator light on top of the machine will come

on when the key switch is first turned on and will begin

flashing when the on-off switch on the control box is

switched on. It will continue to flash while the machine is

running.

1.14 Cold Weather Starting

The engine is equipped with a glow plug system to pre-

heat the intake manifold and improve cold weather starts.

The preheat button (d) is located next to the key switch

on the machine control panel. Hold button in for 10-20

seconds to pre-heat intake manifold.

Crank engine immediately after releasing button.

Do not hold pre-heat button in longer than 30 seconds or

glow plug system may be damaged.

1.15 Shutting Machine Off

Turn vibration off. Unlock throttle control and push it in to

return engine to idle. Set on-off switch (g) to the OFF

position to close fuel valve and stop engine. Turn key

switch (e) on machine off.

Note:

The engine cannot be shut down using the throttle

control alone.The throttle lever only returns the engine to

idle.

1 OPERATION

RT 560/820

1-10

1009SD91

1.16 Emergency Stop

Press emergency stop button (a) at any time during

operation to stop machine. The emergency stop but-

ton disconnects the vibration and travel switches on

the control box. Pressing the stop button does not

shut off the engine.

Before resetting stop button, make sure vibration and

travel switches have been returned to their off posi-

tion and no one is near machine. To reset button, turn

it in direction of arrows.

1.18 Vibration

Two vibration modes are available - high and low. Low

amplitude vibration ( ) is typically used for shallow

lifts where only a thin layer of ground needs to be

compacted, or in areas where heavy compaction could

damage structures, such as over pipes or along the

side of foundations. High amplitude vibration ( ) can

be used in most other applications, and is preferred for

cohesive-type soils with heavy clay content.

Vibration operates only with the machine in the

low speed travel mode.

Vibration is controlled by a three-position switch (e)

located next to the travel switch on the control box. To

start vibration, first set machine to low speed travel

( ), then set vibration switch to either high amplitude

( ) or low amplitude ( ) vibration.

Position switch in the center "0" position to stop vibra-

tion.

Because the exciter weights must reverse direction

when switching between vibration modes, there is a

ten second delay built into the vibration circuit. This

allows time for the weights to come to a complete stop

before changing direction.

CAUTION: DO NOT run vibration over hard surfaces

like concrete or compacted asphalt, drum bearings

can be damaged.

1.17 Travel Speed

Travel speed is controlled by a two-position switch (b)

located on the left side of the control box.

There are two travel speeds available: high speed travel

( ) for movement around the jobsite, and low speed

travel ( ) for compaction.

High speed travel operates only in forward.

When operating in high speed the vibration function

becomes inoperative. Although vibration will automati-

cally stop when switching to high speed, it is recom-

mended that the vibration switch (e) be set to the "0" (off)

position. This will prevent vibration from coming on

unexpectedly when switching back to low speed.

OPERATION 1

RT 560/820

1-11

1.20 Engine Speed

During operation run engine at full throttle (2600 rpm).

This ensures maximum exciter speed and will produce

the best compaction.

1.19 Direction & Steering Control

Two switches on the control box control the motion of the

machine. One controls steering

other direction (d) - forward/reverse. To operate, press

switch with thumb in direction desired. Switches return to

their neutral positions when released.

1.21 Jump Starting

(Protecting Electrical System)

Before jump starting a dead battery make certain that the

battery is good and is only "discharged".

Jump starting a shorted or defective battery will cause the

voltage regulator to supply higher than normal voltage.

This can severely damage the digital electronics that

control machine operation. If there is any doubt as to the

battery's condition, a replacement battery should be

used or an attempt should be made to charge the battery

before starting the machine.

CAUTION: Never disconnect the battery (f) with the

machine running or attempt to run the machine without a

battery. Damage to the the electrical system will occur.

WARNING

Always follow safe procedures when jump starting.

Batteries can emit explosive hydrogen gas. Keep all

sparks and and flames away from the battery. Do

not short circuit battery posts. Do not touch frame or

negative terminal when working on positive termi-

nal.

Follow procedure below when jump starting:

1. Stop the engine on the vehicle with the good battery.

2. Connect one end of positive jumper cable to positive

(+) terminal on good battery and other end to positive

(+) terminal on "discharged" battery.

3. Connect negative jumper cable from negative (-)

terminal on good battery to an unpainted portion of the

machine frame away from the "discharged" battery.

4. Start engine on vehicle with good battery. Allow

discharged battery to charge for a few minutes before

cranking engine.

5. Reverse procedure in steps 3 and 2 to remove jumper

cables. Remove negative cable first.

1.23 Operation on Slopes

When operating on slopes or hills special care must be

taken to reduce the risk of personal injury or damage to

the equipment. Whenever possible, operate machine up

and down hills rather than from side to side to improve

stability and reduce the possibility of a rollover. The

machine is equipped with safety switches which will

interrupt the power to the fuel solenoids should the side–

to–side operating angle exceed 45°. Forward/backward

tilt is not limited by the safety switches. For safe operation

and for protection of the engine, continuous duty use

should be restricted to slopes of 14° (25% grade) or less.

WARNING

MAXIMUM RECOMMENDED SLOPE

14°

25%

NEVER operate machine on side slopes greater than

26° (50% grade). At slopes greater than this, the

machine may roll over, even on stable ground.

1009SD66

1.24 Roll-overs

Proper operation of the machine on slopes will prevent

roll-overs. Read and follow Safety instructions in Sec-

tions

1.2 Operating Safety

and

1.23 Operation on Slopes

If a machine rollover does occur care must be used to

prevent damage to the engine. In this position, oil from the

engine crankcase can flow into the combustion chamber,

which can severely damage the engine next time it is

started. If the machine has rolled on its side, immediate

steps should be taken to right the machine.

CAUTION: To prevent damage to the engine after a roll-

over, the machine must NOT be started, AND must be

serviced to remove any oil that may have been trapped

in the combustion chambers. Contact your local WACKER

dealer or Lombardini Engine dealer for

instructions or servicing.

1.22 Safety Back-Up Bar

A safety bar is mounted to the rear section of the machine

behind the control panel.

The safety bar operates in reverse only!

If the machine backs into an obstruction or for some

reason the operator becomes trapped behind it, the bar

will be pressed forward and stop the machine. The

machine will resume reverse travel when the bar is

released.

HOUR

1.26 Charging System Light

The engine is equipped with an alternator and voltage

regulator to maintain the battery charge. The charging

system warning light (b) indicates the condition of the

battery charging system. Although the machine will run

with the light on for a short period of time, continued

operation will drain the battery and eventually cause the

machine to lose all operating functions.

CAUTION: If operating machine in a narrow trench or

other confined area, drive machine into a safer area as

soon as possible to avoid stranding it in a hazardous or

inaccessible location.
