Hour Meter Product Overview The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance (Figure 6). Fuel Gauge The fuel gauge is located with the hour meter, and the bars light up when the ignition switch is in the On position (Figure 6). The indicator light appears when the fuel level is low (approximately one gallon remaining in the fuel tank).
Blade-control Switch (PTO) Specifications The blade-control switch (PTO) is used to engage the electric clutch and drive the mower blades. Pull the switch up to engage the blades and release. To disengage the blades, push the blade-control switch (PTO) down or move a motion-control lever into the neutral-lock position. Note: Specifications and design are subject to change without notice. Width: Ignition Switch This switch is used to start the mower engine and has 3 positions: Start, Run and Off.
Operation DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Using the Rollover Protection System (ROPS) of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank WARNING Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand. To avoid injury or death from rollover: keep the roll bar in the fully raised locked position and use the seat belt. 1. Park the machine on level ground. Ensure the seat is secured to the machine.
DANGER Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. There is no rollover protection when the roll bar is down. Always keep the roll bar in the raised and locked position and use the seat belt. Read and follow the rollover protection instructions and warnings. To avoid loss of control and possibility of rollover: • Do not operate near drop-offs or near water.
Operating the Mower Blade-control Switch (PTO) The use of protective equipment for eyes, ears, feet, and head is recommended. 1 2 The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.
