Safety Information
Safety is of the utmost importance when operating
turf equipment.
To ensure safe operation of the R52-ELT Golf Greens
Roller, please follow the following safety guidelines.
• Always make a pre-operation inspection before you
operate the machine. If this procedure is not carried
out damage to property or personnel may occur.
• Keep children, pets and inexperienced personnel
away from the machine. This machine should only be
operated by trained and skilled personnel - check with
your supervisor if you are unsure.
• Know how to stop the machine when in motion.
• Never permit inexperienced operators to use the
machine. This machine requires certain knowledge
and expertise to operate it; you must be a trained
person to use this machine. Unskilled persons can
harm themselves and others if they operate this
machine.
• When transporting the roller, make sure the trailer
lock down mechanism is secure to prevent premature
release of the catch. If the trailer catch is not correctly
engaged while towing and releases accidentally, the
front of the roller can drop and dig into the ground,
causing the machine to move dangerously in any
direction causing bodily injury. When carrying out
maintenance ensure the catch is engaged correctly;
if it is not the trailer arm could y up making contact
with a person(s) causing serious injury.
• When motor is running, always keep hands and loose
clothing away from rotating shafts, chains, belts and
sprockets in the transmission area. If hair, clothing or
loose objects become entangled on a rotating shaft
serious injury could occur. Stop before opening safety
cover tted to the transmission area.
• Never ride on the machine when machine is being
towed.
Operator, remember it is your responsibility to be
aware of your surroundings. To avoid accidents, think
safe and operate safe.

Assembly
Assembly Procedure
Step 1: Attaching the left-hand trailer arm to machine
body.
• Locate the trailer arm support axle 30mm in diameter
(1¼”) which extends out on the left side of the
machine, remove the circlip from the support axle. Oil
machined portion. Slide the left hand side trailer arm,
onto the axle, replace the circlip, ensuring the circlip is
located in the groove correctly.
Step 2: Attaching dampener strut and right hand
trailer arm.
• Locate the trailer arm support axle 30 mm in diameter
(1¼”) which extends out on the right side of the
machine, remove the circlip from the axle. Hold the
right side trailer arm in the vertical position and slide
it part way onto the axle. Locate dampener strut.,
remove packing from the unattached end.
• Place strut onto locating pin and push completely on,
insert washer and cotter pin in place to prevent strut
from coming o the shaft.
• If necessary use a soft headed hammer and tap the
trailer arm onto the axle until the circlip groove is
revealed, t the circlip, ensuring it is located in the
groove correctly.
Step 3: Attaching draw bar to trailer arms.
• Locate the draw bar assembly.
• Gather the ends of the right and left trailer arms.
• Place the draw bar assembly between the trailer arms
and align the holes.
• Place one 2¾” x ³/” bolt through each hole, t ³/”
Nyloc nut to each bolt and tighten securely.
• Test to ensure the trailer catch is correctly locking the
trailer arms in the down position and the catch locking
pin ts correctly when transporting the roller, for
safety.
Step 4: Attaching wheels to trailer arms.
• Locate the two wheels for the left and right side trailer
arms.
• Check tires for the correct air pressure, approximately
15psi. Do not exceed this pressure. The tires act as the
suspension, hence the low P.S.I.
• Remove wheel nuts from both hubs, slide wheels onto
hub with air valves facing outwards. Replace wheel
nuts and tighten securely.
• Ensure the taper on the nuts, mate into the wheel
tapers correctly.
Step 5: Correct dampener strut operation
• When the roller is in the trailing position Carefully
hold the draw bar assembly, release the locking catch,
gently with a rm grip begin to raise the draw bar,
when it has travelled suciently the dampener strut
will take over and prevent the trailer arms rapidly
rotating on it’s axle, allowing the roller to lower to the
surface gently. This prevents the operator from being
injured. When the roller is resting on the ground push
the trailer arms back gently, (do not use excessive
force) until the trailer arms will travel no further. The
dampener strut is designed to hold the trailer arms
back behind the operator with the wheels o the
ground.

Step 6: Lubricate smoothing head pivot bearings.
• There is a grease nipple or zirk located on the three (3)
smoothing head centre ball joint swivels. Apply grease
to lubricate ttings.
• Apply grease to the upper main bearing that supports
and carries the three smoothing heads.
Assembly
Operation procedures
Pre-operation checks
• Check batteries are fully charged.
• Ensure steering joystick has no looseness.
• Check that foot pedal depresses under normal foot
pressure and returns to the neutral position.
• Ensure that the draw bar locking catch mechanism is
securely locked to the main draw bar and the safety
pin is tted when trailing the roller.
• Check and tighten grub screws tted to the end
bearing lock rings on the rubber coated drive roller
bearings on each smoothing head and main support
bearing.
• Grease lightly Bearings tted to Drive Roller and
Smoothing Head pivot bearings. Replace plastic caps if
tted.
• Grease rod ends, sparingly.
• Check tire pressure for proper operating pressure
(15psi). Do not over inate.
• Lubricate the drive chain with a suitable chain
lubricant.
Standard operation procedures
• Inspect and check that the roller is serviceable prior to
departing from workshop.
• Use a suitable towing vehicle to move roller from
green to green.
• Maximum recommended towing speed would be
equal to a motorized golf buggy. Approximately
4mph/7kph. Towing at excess speed or across rough
terrain may cause damage to the machine and trailer.
• When approaching the green do not tow the roller
onto the green to set up, put the roller on the fringe
of the green. Put trailer in the up position, start up the
roller and drive it onto the green.
• Greens can be rolled in any direction; take care to
ensure there are no crease lines produced on the
surface.
• When rolling the green hold the accelerator pedal
down to a pre-determind speed and use the
directional control switch tted to the top of the
joystick to change directions, this can be done on
the y. The roller will gently come to a stop and
then gently take o in the opposite direction until
it reaches full speed, which is 8-10 mph. Spinning of
the roller will not occur. The other method is to use
the accelerator pedal to slow down to a stop, change
direction on the switch then accelerate o in the
opposite direction. This is the operators choice. Keep
the roller on the greens surface, it is not necessary to
roll onto the colloars or fringes.
• The gentle take o and stopping is controlled
electronically, it is unlikely that spinning on the green
would be possible; the electronics avoid this from
happening.
• There is no mechanical braking tted to the roller, all
braking is done by the motor which has regenerative
braking built in, this is quite safe, the operator needs
to become familiar with the timing required to stop
and the distance required to do so at the speed being
travelled, remembering the roller is quite heavy.
• If rolling up a steep slope, say o the green ensure

Maintenance
• Ensure the batteries are fully charged before going
to the greens. When you connect the charger you
will notice the needle on the meter will be showing
maximum charge input into the batteries, as the
batteries become charged the needle will fall away to
“0” on the meter, the charger will automatically stop
charging. It is only when this occurs that the batteries
are fully charged.
Ideally it is better to charge the batteries before they
are totally at, if you were to continually atten the
batteries and then recharge, the life of the batteries
will be reduced. Charging can be done at any stage of
use; the batteries do not have a memory that may stop
them from being fully charged.
Until you have charged the unit a number of times,
initially there will be a lot of heat generated from the
charger, the mains lead plugged into the power supply
and the lead connected to the batteries, this is normal
so do not be alarmed.
Important: Use the meter on the battery charger to
indicate the amount of charge in the batteries not the
gauge tted to the roller. This gauge is only a indicator
and does not show an accurate amount of charge in
the batteries.
Storing
• Important: Store this roller in the towing position.
This ensures the trailer strut is in the closed position,
protecting the shaft from corrosion.
• It reduces the load on the bearings.
• Do not store with machine weight on the drive
roller, the internal couplings will distort causing
the drive roller to be out of balance.
Total drive roller replacement would be
required.
Service of the drive chain system
• Replacement - Some chains and belts look
a like, but they are not, use only the chain,
belts and sprockets recommended as per the
correct spare parts number. Wrong pitch drive
chain and belts tted will cause excessive
sprocket wear and possible drive failure.
• Tensioning the drive chain or belt - No
adjustment is required; the chain and belt
tension is automatically adjusted.
Lubrication
• If tted lubricate drive chain with a chain lube
such as Molykote, Innox or ChunkaRocol ITW.
Spray on the inside of the chain so that the
lubricant is forced into each roller and around
each pin prior to rolling of the Greens.
Service of smoothing roller bearings
• Whilst the Roller is suspended by the Trailer,
check operational smoothness of the bearings
tted to each smoothing roller by rotating
the rollers by hand. If bearing tightness,
roughness or excessive looseness is detected,
replace the faulty bearings.
• If bearings are faulty
(a) Remove the complete smoothing head
from the machine, undo the four swivel
mount bolts on upper body, steering rod
and stabilizer rod, wheel the roller away
until the total head is exposed to work on.
Maintenance
Points to remember
• Make sure the roller is serviceable before rolling.
• Ensure batteries are fully charged.
• Start rolling from the fringe of the green.
• Smooth operation on the foot pedal.
• Pick a point on the other side of the green to roll to.
• Do not look at the green close to the roller; it makes it
dicult to steer the roller straight; look well ahead.
• Use ¹/power until you become a procient operator.
• Once you choose your rolling line hold the joystick
steady, correcting direction gently as required.
• Move the steering joystick a little at a time to change
direction; excessive movement of the joystick makes it
dicult to maintain a straight line.
• Move o the green when rolling is complete before
putting the trailer in the down position.
the drive roller (rubber coated) is on the lower side to
maximize the traction. If you try to roll with the drive
roller leading up a steep slope when o the green
spinning will occur.
• Roll the green only, this maximizes the battery power.
• Extra eort is required to raise the roller o the
ground into it’s towing position. An extra extension
bar that pivots open to extend the drawbar which
is magnetically held in place can be extended to
lengthen the drawbar to give the operator more
mechanical advantage making it easier to raise the
roller into it’s towing position.
• Be careful were you uncouple the roller when you
reach a green as it is dicult to move the roller on the
grass, ideally park it on a at surface or on a down hill
to make it easier to connect to the towing vehicle.
• The correct procedure for rolling the green is:
(a) Select the correct direction to roll the green,
remember this roller can roll the greens in all
directions.
(b) Start on one side of the green and work your
way across the green in a zigzag fashion, slightly
overlapping each lap you roll: this makes sure you
miss no part of the green and all of the green is
rolled. Avoid coming back across the green to roll
missed areas if possible. You should be able to
complete the rolling of 18 greens in the same time
or quicker than by mowing using a triplex mower.
• When rolling of the green is completed, move the
roller onto the fringe, stop, lock the trailer into the
trailing position, connect it to the towing vehicle then
move o to the next green to be rolled. Do not put
the trailer down into the towing position on the green;
damage may occur to the green from the roller tires
and body.

Fault Finding
Roller will not move one or either way, check
• Batteries are not at
• Ignition is on
• Chain or Belt are okay
• Sprockets are not worn or slipping on the shaft
• Foot control is operating correctly
• For Sheared Sprocket Keys
Roller will not steer, check
• Woodru Key is in place and not sheared
• Rod ends are connected to smoothing roller head and
the steering arm
• Rod ends are not broken or seized
• Centre swivel bearing on top centre of each
smoothing roller head has not seized
• Connecting rod are in place and serviceable
Smoothing rollers seized, check
• Bearings are OK and not rough or seized
• Replace if necessary
Rubber drive roller will not rotate, check
• Roller shaft end bearings have not seized
• Broken chain or Belt
• Slipping sprockets
• Accumulated dry debris is not locking the
smoothing rollers. (Clean properly after use)
• Internal bolts securing the coupling to the roller tube
loose or came out
Fault Finding
(b) Remove roller shaft bolts from end plates, remove
rollers from the heads.
(c) Screw a bolt back into the shaft end, knock out one
end bearing, then use the same shaft to knock out
the other end bearing.
(d) Fit new bearings, replace rollers into the heads,
lubricate shaft bolts with an anti seize compound
before installing them. Tighten securely and ensure
rollers rotate freely when fully tightened.
(e) Be sure the spacing washers are tted to the shaft
ends before installing the rollers into the heads, in
the correct sequence smaller diameter washer rst
and the larger diameter washer last.
(f) Sometimes, if the rollers do not rotate freely when
installed use a soft headed hammer to hit the
securing bolts on each end of the head, this will seat
all parts and allow the roller to rotate freely.
(g) If the rods are removed or lengths altered ensure
they are correctly adjusted so that the three heads
are parallel to each other when in the straight
ahead position. Adjust if necessary.
Changing transmission oil
• Refer to the manufacturers recommendations.
Contour following drive roller
• Do not disassemble this unit unless you correctly mark
the coupling to tube alignment.
• This is important when re-assembling to ensure the
correct balance is achieved.
• Damage to either section of this roller means a
complete drive roller assembly is required, the supply
