The Travelling Lawn Sprinkler will follow the route of the hose at an average of 0-11mtr per hour with a water pressure of about 2.8 bar. Speed also depends on which of the 3 settings you select, High, Low or Neutral. Your travelling sprinkler can be set to turn off at any point along the hose with the automatic shut-off ramp included. To cover narrow area (5mtr), point the spray arms slightly downward, spin the arm in a clockwork circle to make sure they clear the sprinkler body. For maximum (16mtr) coverage, turn the spray arms upward to an approximate 30° angle.
