variable and is controlled by applying pressure to the drive pedal.
Avoid pressing the drive pedal with a jerky movement, otherwise the hydraulic
system could be damaged as a result.
Negotiate slopes with engine at full speed but sweeper travelling slowly (drive
pedal pressed only ½ way down).

ly.
Avoid braking the sweeper abruptly by pressing the pedal against the
direction of travel, as this could cause damage to the hydraulic system.
