Assembly Procedure
Step 5: 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, ensure it is in the
correct direction as per the manual drawing.
• Place one 2 1/2” x 3/8” bolt through each hole,
fi
t
3/8” 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
fi
ts correctly when transporting
the roller, for safety.
Step 6: 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 18-24psi. 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 7: Correct dampener strut operation
• When the roller is in the trailing position:
1. Carefully hold the draw bar assembly.
2. Lower machine until the front rests on the
ground.
3. Release the locking catch.
4. Gently with a
fi
rm grip begin to raise the draw
bar.
5. When it has travelled su
ffi
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.
