Radiator – Check/clean
EVERY 250 OPERATING HOURS (MONTHLY)
Place the roller on a level surface. Switch
the engine off and push in the reserve/
parking brake knob for all checking and
adjustments on the roller, unless otherwise
specified.
Check that air can flow freely through the radiators (1)
and (2).
A dirty radiator should be blown clean with compressed
air, or alternatively cleaned with a high-pressure washer.
Blow or wash the cooler in the opposite direction to that
of the cooling air.
Be careful when using a high-pressure washer
– do not place the nozzle too close to the
radiator.
Use protective goggles when working with
compressed air or a high-pressure washer.
Check all the rubber elements (1), and replace them all if
more than 25% of the elements on the same side of the
roller have cracks deeper than 10–15 mm (0.4-0.6 in).
Use a knife blade or other pointed tool when carrying
out this check.
Check also that the screw fasteners (2) are tightened.
