Lifting
Where it is necessary to use lifting equipemnt to position the RT60, check and confi rm that the rubber isolators on the operation handle
is not damaged or cracked. If they are cracked or damaged, replace the rubber isolators before attempting to lift the machine. Also
make sure that the lifting equipment has a WLL (Working Load Limit) suitable for the RT60’s weight (See specifi cation chart or the
machine number plate). Attach suitable chains or slings ONLY to the lifting point on top of the RT60’s operating handle.
•
NEVER leave the engine running whilst transporting or moving the RT60, even if it is only a short distance.
•
The height of the operating handle can be adjusted within the range of 850 ~ 880 mm. Loosen three bolts at each side of the
operating handles base, and retighten them at the desired handle height. Note, that when the handle is set too high,
excessive vibration may be transmitted through the handle.
Having carried out the checks listed in the ‘pre-start’ section, you may start the engine.
The Belle Group RT60 range of tampers are fi tted with a centrifugal clutch, thisallows the engine to run at idle without driving the crank
mechanism. As the engine speed is increased the clutch will engage and the engine will drive the crank mechanism.
•
To avoid damage to the centrifugal clutch, move the throttle lever quickly from the L to H position. For correct operation, the
engine speed should be set to maximum.
•
Avoid operating the machine on a fully compacted, hard, or non-yielding surface. Otherwise, the gear transmission mechanism
will be damaged, and the life of the machine will be greatly reduced.
•
When working in a narrow trench, if the ramming shoe should get caught between the walls of the trench, the rammer may miss-
strike and can be severly damaged. The ramming shoe may especially be damaged severely.
•
Make certain that the rammer is steered only by using the handle grip. It should only be pushed. The rammer must not be
pressed into the materials being compacted. Excessive pressure on the operating handle will lead to the unsatisfactory
compaction due to the fact that the jumping action is hindered.
Transportation.
When transporting or storing the machine, place the machine in an upright position if at all possible. Should the machine be required to
be laid down, NEVER attempt to lay the machine in a manner that the air cleaner faces downwards. Otherwise, the oil in the cylinder
may get into the combustion chamber or in the air cleaner, which may result in starting diffi culties. Laying the machine forwards (The
crankcase cover of the rammer facing downwards) may not cause any spill of the engine oil into the cylinder or air cleaner of the en-
gine. However, if the engine is still hot, spilt fuel on the engine may cause fi re. Lay the machine after the machine is completely cooled.
The machine fi tted with the transporting roller on the operating handle may be easily loaded to and unloaded from a vehicle. Tilt the
machine forwards until the transporting roller touches the fl oor of the vehicle. Lift the lower part of the machine using the grab handle
provided at the ramming shoe, and push forward to load the machine. During transportation, the machine should be tied fi rmly, and
placed in an upright position if at all possible. To unload the machine, tilt the machine forward, until the roller touches the fl oor. Slightly
lift the lower part of the machine, and pull the machine out.
Operation at High Altitude
For continuous High-Altitude operation above 1,000m (3,000FT), it will be necessary to change the engine main jet to a type that will allow
for correct fueling of the engine. Otherwise, the unit will suffer from a lack of engine power and not work correctly.
Please contact BELLE group companies for details.
