Maintenance; Periodic Maintenance - Exmark Laser Z Ultra Vac Operator's & Parts Manual

POTENTIAL HAZARD
♦ Loading a unit on a trailer or truck increases the possibility of
backward tip-over.
WHAT CAN HAPPEN
♦ Backward tip-over of the unit could cause serious injury or
death.
HOW TO AVOID THE HAZARD
♦ Use extreme caution when operating a unit on a ramp.
♦ Use only a single, full width ramp; DO NOT use individual
ramps for each side of the unit.
♦ If individual ramps must be used, use enough ramps to create
an unbroken ramp surface wider than the unit.
♦ DO NOT exceed a 15° angle between ramp and ground or
between ramp and trailer or truck.
♦ Avoid sudden acceleration while driving unit up a ramp to
avoid tipping backward.
♦ Avoid sudden deceleration while backing unit down a ramp to
avoid tipping backward.
2. Loading a Unit: Empty grass bags before attempting to load unit on trailer or truck.
Use extreme caution when loading units on trailers or trucks. One full width ramp that is
wide enough to extend beyond the rear tires is required instead of individual ramps for
each side of the unit. The lower rear section of the tractor frame extends back between
the rear wheels and serves as a stop for tipping backward. Having a full width ramp
provides a surface for the frame members to contact if the unit starts to tip backward. If it
is not possible to use one full width ramp, use enough individual ramps to simulate a full
width continuous ramp.
Ramp should be long enough so that the angles between the ramp and the ground and the
ramp and the trailer or truck do not exceed 15°. A steeper angle may cause mower deck
components to get caught as the unit moves from ramp to trailer or truck. Steeper angles
may also cause the unit to tip backward. If loading on or near a slope, position the trailer or
truck so it is on the down side of the slope and the ramp extends up the slope. This will
minimize the ramp angle. The trailer or truck should be as level as possible.
DO NOT attempt to turn the unit while on the ramp, you may lose control and drive off the
side.
Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing
down a ramp. Both maneuvers can cause the unit to tip backward.

5. MAINTENANCE:

5.1 PERIODIC MAINTENANCE

IMPORTANT: Before conducting any maintenance, shut off deck drive, stop engine and
wait for all moving parts to stop. Remove spark plug wire(s) or remove key.
5.1.1 Blower Housing/Impeller
Inspect for wear or damage daily. Replace or repair worn parts as needed.
Note: When mowing in areas with sandy soil, use low lift blades on the cutting
deck and higher cutting heights to minimize wear on the blower components.
WARNING
Service Interval: Daily.
