– Check/Cleaning
Open the left-hand door to the engine compartment to
gain access to the radiator and the hydraulic fluid
cooler.
Ensure that air can flow unrestricted through the cooler
and radiator, (1), (2) and (3).
Blow a dirty cooler and radiator clean with compressed
air, or wash using a high-pressure washing jet.
Take care when using a high-pressure
washing jet, do not hold the nozzle too close to
the cooler.
Use protective goggles when working with
compressed air.
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.
