SET-UP Equipment set-up 1. Remove crate top and sides. 2. Remove upper handle bar assembly and lay aside. HARDWARE 3. Open bag containing loose hardware. WASHERS (2) COTTER PINS (2) 4. Using four (4) screws, flat washers and nuts attach the upper handle bar assembly to lower handle bar assembly. See Figure 1. UPPER HANDLE BAR ADJUSTING ROD NOTE: Handle fit is tight. When aligning holes use a tapered type pilot to help align holes (i.e. punch or phillips style screw driver). COTTER PIN (1) 5.
SET-UP 8. Attach the yoke to the brake’s top mounting hole using the clevis pin and cotter pin. Make sure the rod is positioned in the bracket as shown in Figure 4. NOTE: Adjust the brake before inserting hair pin. To engage brake, pull back on handle until brake rod assembly goes “over center” and locks the brake ON. Turning the yoke clockwise shortens the rod tightening the grip on the brake disc by the brake pads. counterclockwise loosens the clamping force.
SET-UP ENGINE THROTTLE CONTROL LEVER 14. Insert “L” end of throttle cable into the outside hole of the engine throttle control lever. Figure 7. THROTTLE CABLE FORWARD FIGURE 7 15. Attach the throttle cable to the engine using the double wire clamp removed in step nine. Figure 8. 16. Test throttle control by pulling back throttle handle on console. Throttle arm on engine should be pushed completely forward. Cable should not slip in clamp when doing this test. 17.

CONTROLS Starter The starter is of the magnapull type with spring return. To replace the return spring or starter cord, contact an authorized service workshop. Starter handle Misuse of the starter handle can damage the starter. Do not twist the starter cord around your hand. Pull out the handle slowly until the gears mesh. Do not pull out the starter cord completely and do not let go of the starter handle when extended.
CONTROLS Spark plug The engine spark plug is hidden under the ignition cable shoe. When performing service, it is important that the engine cannot start accidentally. For this reason, always remove the ignition cable shoe from the spark plug. To avoid pulling the cable, the cable shoe is equipped with a special handle; see the illustration. Type of spark plug, see “Technical data”. Service instructions, see “Maintenance/Electrical system”.
CONTROLS Fuel tank Underneath the tank, there is a fuel filter combined with the fuel valve. The tank volume is 1.72 Gal. (6.5 liters) Fueling Read the safety instructions before fueling. Keep the fuel and fuel tank clean. Avoid filling the machine with dirty fuel. Make sure the fuel cap is properly tightened and the gasket is not damaged, particularly before washing the machine. Use unleaded gasoline with minimum 86 octane rating. Never use gasoline mixed with two-cycle oil.
CONTROLS Throttle . The lever controls engine speed. With the lever down, the engine runs at idle and functions as start position. When the engine speed increases, the centrifugal clutch drive automatically engages the cutting wheel. On/Off Engine switch on the panel The ON/OFF engine switch can be used to stop the engine. The illustration shows the toggle switch in the OFF position (short circuited electrical system).
OPERATION Starting the engine Check that all daily maintenance as described in the maintenance schedule has been performed. Check that there is sufficient fuel in the tank. Fuel valve Open the fuel valve. Place the lever all the way to the right. FUEL VALVE 8011-182 Choke control When starting the engine warm, the lever should be in the right position; see the illustration.
