Having carried out the checks listed in the 'pre start' section, you may start the engine.
The Belle Group BWR-Series Hand-Guided Rollers are ¿ tted with a centrifugal clutch; this allows the engine to run at idle without
driving the Hydraulic pump.
As the engine speed is increased the clutch will engage and the engine will drive the Hydraulic Pump to send the hydraulic
power to drive the drums, and to drive the vibration mechanism as well. To avoid any damage to the centrifugal clutch, move
the throttle lever quickly from L to H position. For correct operation, the engine speed should be set to maximum during the
compaction operation
·
Avoid operating the machine on a fully compacted, hard, or non-yielding surface. Otherwise, the bearings and other
mechanical components will be damaged, and the life of the machine will be greatly reduced.
·
When working on a steep slope, pay extra care in operating the machine so that the machine may not collapse or fall down.
Always work up or down the slop. Do not work across the slope.
·
When the machine is going reverse, make sure not to stand behind the Operation Handle. Always walk along the Operation
Handle and face toward the direction of travel.
·
Lifting
Where it is necessary to use lifting equipment to position the BWR, make sure the lifting equipment has a WLL (Working Load
Limit) suitable for the machine's weight (see speci¿ cation chart on page 5 or the machine number plate.) Attach suitable
chains or slings ONLY0to the lifting point Provided at the center of the machine (One-Point Hook) or at each corner of the
machine (Lifting Eyes).

TRANSPORTATION
Transportation on a vehicle.
Make sure to lock the Handle and use proper slopes of suf¿ cient width, length, and strength on loading to and unloading from

close to the operation handle to avoid any injury.
Apply the parking brake, and tie the machine ¿ rmly to the vehicle during the transportation.
