PRESENTATION Presentation This operator’s manual describes the Husqvarna Lever-Steered Rider. The rider is fitted with a Kawasaki four-stroke V-Twin engine developing 23/25 horse power. Transmission from the engine is made via two belt-driven hydraulic pumps, which in turn drive a hydraulic motor for each drive wheel. Using the left and right steering controls, the flow is regulated and thereby the direction and speed. 8011-583 Lever-Steered Rider 8011-602 Locations of the controls Control Locations 1.
PRESENTATION Choke Control The choke control is used for cold starts in order to provide the engine with a richer fuel mixture. For cold starts the control shall be pulled out. 8011-508 Choke control Throttle Control The throttle control regulates the engine speed and thereby even the rate of rotation of the blades, assuming the control for engaging the mower deck is pulled out, see Engaging the Mower Deck.

MAINTENANCE Start motor Ignition system Works Does not work 8011-553 Safety system English-28
MAINTENANCE Checking the Engine's Cooling Air Intake Check that the engine’s cooling air intake is free from leaves, grass, and dirt. If the cooling air intake is clogged, engine cooling deteriorates, which can lead to engine damage. 8011-625 Checking and Adjusting the Throttle Cable Check and clean the cooling air intake Check that the engine responds to throttle increases and that a good engine speed is attained at full throttle. If doubts arise, contact the service workshop.
MAINTENANCE Replacing the Air Filter If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a soiled air filter, the spark plugs can obtain a coating that disrupts operation. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).
MAINTENANCE Replacing the Fuel Filter Replace the line-mounted fuel filter every 100 hours (once per season) or more regularly if it is clogged. Replace the filter as follows: 1. Move the hose clamps away from the filter. Use flat-nosed pliers. 2. Pull the filter loose from the hose ends. 3. Push the new filter into the hose ends. Position the filter with the ”FLOW” arrow pointing up toward the fuel pump. If necessary, a soap solution can be applied to the filter ends to ease mounting. 4.
MAINTENANCE Checking the Parking Brake Visually check that no damage is found on the lever, links, or switch belonging to the parking brake. Perform a test drive and check that there is a braking effect. To adjust the handbrake, contact the service workshop. 8011-511 The parking brake in the disengaged position Checking the Blades In order to attain the best mowing effect, it is important that the blades are well sharpened and not damaged.
