To get a good result
• Always run the engine at full throttle or near full
throttle.
• Always adapt the speed of the product to the
snow situation and adjust the speed with the
drive speed control lever. Make sure that the
product throws snow evenly.
• It is easier and more efficient to remove snow
immediately after it falls.
• Always throw snow downwind whenever
possible.
• On flat surfaces, like asphalt roads, raise the skid
plates up to 5-6 mm (0.2-0.25 in) off the ground.
• The scraper bar is reversible. When it becomes
worn almost to the edge of the housing, reverse
it. Replace the scraper bar if it is damaged, or if
both sides are worn.
• Do not dispatch the chute deflector if it is
clogged.
• If the product does not move forward due to
unforeseen circumstances, release the drive
engagement immediately or move the ON/OFF
key to the "OFF" position.
