Pre-Start; Mowing - Exmark Lazer Z HP Operator's Manual

Brake must be engaged, motion control levers out (neutral lock position) and
PTO switch "OFF" to start engine. (It is not necessary for the operator to be in
the seat to start the engine.)
3.1.9 Hour Meter: Located on the right fuel tank.
The hour meter is connected to a pressure switch installed in the engine block and
it records the number of hours that the engine has run. If ignition switch is left on
without engine running, hour meter will not run.
NOTE: This switch is not a low oil sensor and will not alert the operator if the engine
oil is low.
3.1.10 Fuel Shut-Off Valve: Located in the fuel line beside the engine, near the fuel filter.
Rotate the valve 1/4 turn clockwise to shut off fuel. Rotate the valve 1/4 turn
counter-clockwise to turn on fuel.
3.1.11 Fuel Gauge: Located on the left fuel tank. The fuel gauge monitors the amount of
fuel in both tanks. Fuel is used evenly from both tanks.
3.1.12 Drive Wheel Release Valves: Located on the right front corner of the hydrostatic
pumps. Drive wheel release valves are used to release the hydrostatic drive
system to allow the machine to be pushed without the engine running. Unhook
seat latch and tilt seat up to gain access to pumps.
With a 5/8 wrench, turn both valves one turn counter-clockwise to release drive
system.
Turn clockwise to reset system. DO NOT overtighten. DO NOT tow machine.

3.2 PRE-START

3.2.1 Fill fuel tanks. For best results use only clean, fresh regular grade unleaded gasoline
with an octane rating of 87 or higher. Regular grade leaded gasoline may also be
used; however, combustion chamber and cylinder head will require more frequent
service. See Engine Owner's Manual. DO NOT add oil to gasoline.
Do Not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a
level that is 1/2" below the bottom of the filler neck to allow for fuel expansion and
prevent fuel spillage.
3.2.2 Make sure you understand the controls, their locations, their functions, and their
safety requirements.
3.2.3 Refer to Maintenance, Section 4, and perform all the necessary inspection and
maintenance steps.

3.3 MOWING

3.2.1 Operate units with the roll bar in the raised and locked position and use seat belt.
There is no rollover protection when the roll bar is down. If it is necessary to lower
roll bar do not wear the seat belt. Raise the roll bar as soon as clearance permits.
3.3.2 Open fuel shut-off valve.
3.3.3 Starting Engine:
Brake must be engaged, the PTO switch disengaged, and the motion control
levers out (neutral lock position). (The operator does not need to be in the seat
to start the engine.)
On a cold engine, place the throttle midway between the "SLOW" and "FAST"
positions and push choke lever forward to the "ON" position. Turn ignition switch
to the "start" position. Release the switch as soon as the engine starts.
IMPORTANT: DO NOT crank the engine continuously for more than ten (10)
seconds at a time. If the engine does not start, allow a 60 second cool-down
period between starting attempts. Failure to follow these guidelines can
burn out the starter motor.
