  • Page 29: Mowing Tips

    Mowing Tips • Observe and mark rocks and other fixed objects in order to avoid collisions. • The cutting deck should be properly leveled for best mowing performance. The blades should be parallel to the ground or slightly tipped down in the front.
  • Page 30 • Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and the grass clippings will fasten under the cowling. • Hose the mower deck with water after each use. Hose especially underneath. Do not spray high pressure spray directly on top of spindles.
  • Page 31: Stopping

    Stopping Emergency stop Release both hands from the operator presence lever handles. When both operator presence levers return to their outer position, the engine will quit and the mower will stop. Pull both motion control levers firmly against handle grips and hold them securely in place. Use thumb latches to lock both motion control levers in neutral positions.
  • Page 32: Stopping The Engine

    Stopping the Engine Allow the engine to idle a minute in order to attain normal operating temperature before stopping it, if it has been worked hard. Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling. When the machine is standing still, activate the parking brake by moving the thumb latches to the park brake position.
  • Page 33: Adjustment Of Cutting Height

    Adjustment of cutting height The cutting height can be adjusted by three methods: • Moving spacers between the upper side and the lower side of the caster swivel according to "Cutting height table".

If adjustments are necessary, they can be made as follows for the cable: Loosen the clamping screw for the cable’s outer casing.
  • Page 42: Kawasaki Engine Air Filter

    Kawasaki Engine Air Filter If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a dirty air filter, the spark plugs can become fouled and disrupt operation. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).
  • Page 43: Kohler Engine Air Filter

    Kohler Engine Air Filter If the engine seems to lack power or runs rough the reason may be that the air filter is clogged. It is therefore important to service the air filter at regular intervals (see “Maintenance Schedule” on page 35 for correct service interval).
  • Page 44: Replacing The Fuel Filter

    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: Move the hose clamps away from the filter. Use flat-nosed pliers. Pull the filter loose from the hose ends. Push the new filter into the hose ends.
  • Page 45: Checking The Parking Brake

    Checking the Parking Brake Visually check that no damage is found on the thumb latches. Perform a test drive and check that there is a sufficent braking action. To adjust the brake, contact the service workshop if you are uncertain. Set the thumb latches in the neutral locked position.
  • Page 46: Checking The Blades

    Checking the Blades In order to attain the best mowing effect, it is important that the blades are well sharpened and not damaged. Bent or cracked blades or blades with large nicks must be replaced. Check the blade mounts. IMPORTANT INFORMATION The replacement or sharpening of blades should be carried out by an authorized service workshop.
  • Page 47: Cleaning And Washing

    Cleaning and Washing Regular cleaning and washing, especially under the mower deck, will increase the machine’s lifespan. Make it a habit to clean the machine directly after use, before the dirt sticks. Do not spray high pressure water directly on the top of the deck. Caster Wheels Check every 200 hours.

  • Page 53 LUBRICATION The oil level should lie between the markings on the dipstick. If the level is approaching the ”ADD” mark, fill the oil to the ”FULL” mark on the dipstick. Never fill above the ”FULL” mark. The oil is filled through the hole for the dipstick.
  • Page 54 Kohler Engine Changing the Engine Oil Change oil after every 100 hours of operation (more frequently under severe conditions). Refill with service class SG, SH, SJ or higher oil as specified in the Viscosity Grades table on page 54. Change the oil while the engine is still warm. The oil will flow more freely and carry away more impurities.
  • Page 55 Checking the Oil Level The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use as follows: Make sure the engine is stopped, level, and is cool so the oil has had time to drain into the oil pan.
  • Page 56 Oil Recommendations Using the proper type and weight of oil in the crankcase is extremely important. So is checking oil daily and changing oil regularly. Failure to use the correct oil, or using dirty oil, causes premature engine wear and failure. Oil Type Use high quality detergent oil of API (American Petroleum Institute) service class...
