2.1 Operating Safety
FAMILIARITY AND PROPER TRAINING ARE REQUIRED FOR THE SAFE OPERATION OF EQUIPMENT.
WARNING Equipment operated improperly or by untrained personnelcan be dangerous. Read the
operating instructions contained in boththis manual and the engine manual and familiarize yourself with
thelocation and proper use of all controls. Inexperienced operators shouldreceive instruction from
someone familiar with the equipment beforebeing allowed to operate the machine.
2.1.1 ALWAYS read, understand, and follow procedures in the Operator’s Manual before attempting to operate the
equipment.
ALWAYS disengage and stow the locking bar for the articulated steering joint before operating the machine. The
machine cannot be steered when the locking bar is engaged.
2.1.2 ALWAYS check that all controls are functioning properly immediately after start-up!
DO NOT operates the machine unless all controls operate correctly.
2.1.3 ALWAYS remain aware of changing positions and the movement of other equipment and personnel on the job site.
2.1.4 ALWAYS remain seated at all times while operating the machine
2.1.5 ALWAYS remain aware of changing surface conditions and use extra care when operating over uneven ground, on
hills, or over soft or coarse material. The machine could shift or slide unexpectedly.
2.1.6 ALWAYS use caution when operating near the edges of pits, trenches or platforms. Check to be sure that the
ground surface is stable enough to support the weight of the machine with the operator and that there is no danger of the
roller sliding, falling, or tipping.
2.1.7 ALWAYS wear protective clothing appropriate to the job site when operating equipment.
2.1.8 ALWAYS keep hands, feet, and loose clothing away from moving parts of the machine.
2.1.9 ALWAYS read, understand, and follow procedures in the Operator’s manual before attempting to operate the
equipment.
2.1.10 ALWAYS stores the equipment properly when it is not being used. Equipment should be stored in a clean, dry
location out of the reach of children.

and save water.
Note: Press the “Menu key”, “Time of spray on” start to flash, then press “Adjust key” to adjust time. Then press again the
“Menu key”,“Time of spray on” set up and stored in the system.
At same time, “Time of spray off” start to flash, and then press the “Menu key” third time, “Time of spray off”
set up and stored in the system. The light flash 10 seconds, if don’t operate within 10 seconds, will store to
system automatically and stop flash.
If any fault lights on, the buzzer will ring. Please check the machine faults.
10) Spray water switch
11) Working lamp switch
It controls the on/off of working lamp. Open the working lamp when night construction.
12) E-stop button
When press down the e-stop button, forward/backward stop, vibration stop, and engine stops
4.7 Stopping/Parking
4.7.1 Turn vibration off.
4.7.2 Close both watering valves.

WWW.TMGINDUSTRIAL.COM 11 /48 Toll Free:1-877-761-2819
4.7.3Return the engine throttle to idle by pressing the throttle switch,and allowthe engine to cool down.
4.7.4Stop the engine by turning the ignition switch to OFF.
4.7.5 Set the parking brake. Alwaysset the parking brake before leaving the machine.
Note: The parking brake engages the rear drum only .
CAUTION: Avoid parking the roller on a hill or an incline. If the rollermust be parked on a hill, block the drums in addition
to setting thebrake to prevent the roller from moving.
4.8 Direction and Speed
The forward/reverse lever controls both the direction and speed of theroller. Use the control lever, rather than the throttle,
to control thespeed of the machine while compacting.Daily, before operating, check the machine for drift (movement
with theforward/reverse control in the NEUTRAL position) and adjust asneeded. See section Adjusting the Drive Control
Cable .
Speed is controlled by the amount the lever is moved in the directionof travel—forward or reverse.
While operating the machine, run it at full throttle. To run the machineat full throttle, press and release the throttle switch.
This ensuresmaximum travel speeds and will produce the best compaction results.Operating the machine at slower
engine speeds will reducecompaction, slow down machine functions, and damage hydrauliccomponents.
4.9 Braking Machine
The machine will brake automatically when the control lever is returnedto neutral. If the machine continues to drift, shift
the control leverslightly in the opposite direction to stop movement and then return thelever to neutral. If the machine will
not remain stationary in neutral,adjust it.
Emergency stop pushbutton
When pushed, the emergency stop pushbutton not only stops all travel(either forward or reverse) and applies the brake,
but also stops excitervibration.
4.10 Vibration
CAUTION: If the machine has been turned off with the vibration on, thevibration will come on as soon as the machine is
restarted. Therefore,for easier starting and to keep the surface finish smooth, be ready toswitch vibration off should it
come on while cranking the engine.
4.11 Watering System
The watering system is controlled by two valves, one for each drum.
The valve handles are located to the right of the operator. Rotatethe valve handles to control the amount of water being
applied to thedrum.
4.12 Articulation Joint Lockarm
A lockarm, located above the articulated joint, is provided to securethe front and rear halves of the roller together. Once
secured, thelockarm prevents the two halves from swinging together.
To avoid being pinched by machine halves, set the lockarm

WWW.TMGINDUSTRIAL.COM 12 /48 Toll Free:1-877-761-2819
WARNINGbefore lifting the machine for transport or repairs!
To set lockarm, release it from its holder and swing it out from its storedposition. Place theforward
end of the arm into the hole provided in thefront frame of the machine. Secure it in this position using
the largehairpin cotter provided.
4.13 Adding Ballast to Rear Drum
The rear drum can be filled with ballast to provide additional weight.Add ballast through plug opening.If water is used as
ballast, add antifreeze or drain drum after use, inareas where temperatures are below freezing.
4.14 Roll Over Protection Structure (ROPS)
The machine is fitted with a Roll Over Protection Structure (ROPS).
The machine is normally delivered to the customer with the ROPSfolded forward to facilitate transport.
Before using the machine, position the ROPS in the fully uprightposition as follows:
4.14.1Support the ROPSusing a crane and suitable rigging capable of
supporting 48 kg. (105 lbs.), or two individuals capable of supportingthe ROPS.
4.14.2 Loosen the screws(one on each side) without removing them.
4.14.3 Raise the ROPS to the upright position.
4.14.4 Insert the screws into the holesand torque all screws to 120 Nm
(88 ft.lbs.).
4.14.5 Remove the rigging from the ROPS.
CAUTION: Do not use the ROPS to lift the machine.
WARNING Each month, check that the screws holding the ROPS in place aretight. Check that the ROPS
frame is not rusty, cracked, broken ordamaged in any way.
If the frame has been removed from the machine, it must be reinstalledbefore the machine is used. When reinstalling a
safety frame, use theoriginal nuts and bolts.
Keep the safety frame upright when working with the roller, and
WARNING use the safety belt provided.
4.15 Hour Meter / Tachometer
The hour meter/tachometeris located on the steering column.When the engine is running, it acts as a tachometer. When
the engineis shut down, it records the actual running time of the engine. Use then hour meter when planning scheduled
maintenance.
4.16 Operation on Slopes
When operating on slopes or hills special care must be taken to reducethe risk of personal injury or damage to the
equipment. Alwaysoperate the machine up and down hills rather than from side to side.For safe operation and for
protection of the engine, continuous dutyuse should be restricted to front/rear slopes of 17°(30% grade) or less.

WWW.TMGINDUSTRIAL.COM 13 /48 Toll Free:1-877-761-2819
NEVER operate machine on side slopes. The machine may roll
WARNING over,even on stable ground.
4.17Battery Disconnect
Isolate the battery using this switch before performing any
WARNING maintenance operations on electrical equipment.
