OPERATION HOW TO USE YOUR MOWER TO USE THROTTLE CONTROL (See Fig. 3) TO SET PARKING BRAKE (See Fig. 3) Always operate engine at full throttle. The Throttle control is equipped with a choke detent. Pressing the throttle control all of the way forward will choke the engine. For full throttle, press throttle control forward until you feel resistance. • Operating engine at less than full throttle reduces the battery charging rate • Full throttle offers the best mower performance.
OPERATION NOTE: To begin motion the operator must be in the seat and the parking brake disengaged before the motion control levers can be moved from the neutral slots or the engine will kill. Fig. 4 and 4A. FORWARD REVERSE By moving the levers an equal amount forward or back the machine will move in a straight line in that direction. Fig. 4 and 4A CONTROL LEVER Movement of either lever forward will cause the right or left wheel to rotate in a forward direction.
OPERATION FOOT PEDAL ANTI-SCALP ROLLER LIFT ARM HEIGHT PLATE CZ-8 FIGURE 6 FIGURE 5 TO OPERATE MOWER TO ADJUST ANTI-SCALP ROLLERS (See Figure 6) Your mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the park brake will shut off the engine. • Select desired height of cut. • Start deck blades by pulling the PTO switch up into the engaged position.
OPERATION • • • The slowest speed possible should be used before starting up or down hills. Avoid stopping or changing speed on hills. If stopping is absolutely necessary, pull drive levers into the neutral position and push to the outside of the unit and engage the park brake. IZT BYPASS LINKAGE IMPORTANT: Control levers return to neutral when released. This may cause a sudden stop of the mower. • • • CZ-10 To restart movement, release the park brake.
OPERATION BEFORE STARTING THE ENGINE CAUTION Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it the run until the fuel lines and carburetor are empty.
OPERATION NOTE: Before starting, read the warm and cold MOWING TIPS starting procedures below. • Insert key into the ignition and turn the key clockwise to “START” position and release the key as soon the engine starts. Do not run the starter continuously for more than 15 seconds per minute. If the engine does not start after several attempts, push the throttle control into the choke position, wait a few minutes and try again.
