Training
What is LPG? LPG stands for liquefied petroleum
gas and is more commonly called propane. LPG is
a liquid fuel that is stored in a tank under pressure.
Before the liquid leaves the tank, it is converted into
a vapor. Since LPG is stored as both liquid and gas,
it may leak from joints or connections that are not
sealed properly. LPG becomes flammable when it is
mixed with air.
5
Safety
CAUTION
DANGER
This machine produces sound levels in
excess of 85 dBA at the operator’s ear and
can cause hearing loss through extended
periods of exposure.
LPG fuel is extremely flammable and vapors
are explosive.
Wear hearing protection when operating this
machine.
• Never smoke around tank(s) and stay
away from an open flame or where fumes
may be ignited by a spark.
A fire or explosion from LPG fuel can burn
you, others, and cause property damage.
• Inspect the area where the equipment is to be
used and remove all rocks, toys, sticks, wires,
bones, and other foreign objects which can be
thrown by the machine and may cause personal
injury to the operator or bystanders.
• Extinguish all sources of spark or flame
when approaching LPG tanks or mowers.
The hazard increases for enclosed trailers
or storage locations where vapor leakage
may occur and collect.
• LPG is heavier than air and may
accumulate in low lying areas, such as
ditches, drains, or pits.
• LPG tank(s) should be filled by trained
and qualified personnel ONLY.
• Never tamper with or repair the tank(s);
contact trained and qualified personnel.
• Do Not change the tank(s) when the
engine is running.
• Before disconnecting the hose(s), purge
all LPG vapors from the system, by
closing the fuel valve(s) on ALL tanks and
allowing the engine to run until it stops.
• Store the tank(s) away from heat, sparks,
or open flames.
• Do Not operate without entire exhaust
system in place and in proper working
condition.

Safety
DANGER
DANGER
LPG fuel is extremely flammable and vapors
are explosive.
LPG vapors and liquid escaping from the
tank may cause serious injury or death.
Vapors or liquid may cause suffocation,
freezing of tissue, or frostbite.
• In case of fire take the following steps:
1. If you can safely do so, stop the flow of
gas as quickly as possible. Never put
out flame unless gas can be shut off.
• Store and service the mower in a well
ventilated area.
2. Notify the Fire Department and clear
immediate area of all people.
• An approved LPG detector installed
in trailers and storage areas is
recommended.
3. When gas flow is stopped, put out
the fire. Usually when flow of gas is
cutoff, fire will automatically stop.
• LPG is heavier than air and may
accumulate in low lying areas, such as
ditches, drains, or pits.
4. If gas flow cannot be immediately
stopped, direct water on tanks to keep
them cool, but Do Not put out fire.
• Avoid breathing of vapors.
• Keep away from vent valve.
• Storage locations and trailers should
be equipped with at least one approved
portable fire extinguisher having a
minimum capacity of 18 lb (8.2 kg) dry
chemical with a B:C rating. Do Not
use Carbon Tetrachloride extinguishers
(Pyrene etc.).
• Keep away from eyes and skin.
• Contact trained and qualified personnel if
tank shows signs of frosted areas, makes
a hissing sound, or emits a foul odor.
• Obtain immediate medical attention if
contact occurs with vapors or liquid.
• Check that the operator’s presence controls,
safety switches, and shields are attached and
functioning properly. Do Not operate unless they
are functioning properly.
Inspection
It is very important to check the LPG tank and
components for wear or leaks.
Important: Never check for leaks using an open
flame.
Important: Never use bare hands when
checking the fitting or valve. Escaping LPG
vapor and liquid freezes skin on contact.
Important: Only hand tighten tank connection
fitting. Over tightening by the use of tools may
cause damage. If hand tightening does not stop
a leak, contact trained and qualified personnel
immediately.
• Before each use:
– Visually inspect the tank, hose, and fitting and
be alert to a foul odor coming from the tank.
7
Safety
– The LPG tank should be free of dents or
damage. If the tank show signs of dents or
damage, replace it immediately.
so, remove the tank from your mower;
otherwise, contact trained and qualified
personnel immediately.
– Check the valve and fitting openings for dirt
and debris.
◊ If no bubbles are detected, the LPG tank
may be used.
– Slowly open the valve all the way and listen
for a continuous hiss from the regulator, it
may indicate a leak.
• Weekly:
– Check the entire LPG fuel delivery system for
damage or deterioration.
– LPG has a rotten egg or skunk smell added
to it to help detect a gas leak. If you detect
a gas leak:
– Check the entire LPG fuel delivery system for
leaks at all joints using the same method as
described in the previous section.
◊ Turn off the LPG valve if you can safely
do so.
– Follow all the inspection checks as specified
in the two previous inspection sections.
◊ Leave the area.
• Tank Requalification:
◊ Contact trained and qualified personnel
immediately.
– USDOT (United States Department of
Transportation) regulations require LPG
tanks to be inspected, requalified, and marked
within 12 years of the manufacture date and
on a regular basis thereafter. Typically this
occurs when the tank is refilled; contact a
trained and qualified LPG tank provider for
more details.
– Do Not use if the hoses are abraded, damaged,
kinked, or flattened.
– Make sure the tank is securely mounted to
the mower. If the tank is loose, the hose or
fittings may leak.
• With each tank change:
– Check all gauges, fittings, and valves for
damage.
– Do Not fill the LPG tank if it is beyond the
requalification period.
– Look for deterioration, damaged or missing
o-rings on tank connection fitting.
– Do Not fill damaged or rusted LPG tanks.
Operation
– Inspect the LPG tank and the fuel connection
joint for leaks. Use the following procedure
below to detect leaks:
WARNING
◊ Apply an approved leak detector solution,
obtained from a trained and qualified
LPG distributor, or a thick non-ammonia
soapy water solution (50% non-ammonia
soap and 50% water). (A leak detector
solution that contains ammonia will cause
the fittings to corrode and leak.)
Operating engine parts, especially the
muffler, become extremely hot. Severe burns
can occur on contact and debris, such as
leaves, grass, brush, etc. can catch fire.
◊ Using a small brush or spray bottle, apply
the solution around all the fittings of the
LPG tank and the fuel connection joint.
• Remove accumulated debris from muffler
and engine area.
• Allow engine parts, especially the muffler,
to cool before touching.
• Install and maintain in working order a
spark arrester before using equipment
on forest-covered, grass-covered, or
brush-covered unimproved land.
◊ Slowly open the gas valve a half-turn.
◊ If bubbles are detected, the joint or fitting
has a leak. Shut off the valve, tighten
the leaking connection, and slowly open
the valve again. If bubbles still appear,
Do Not use the tank. If it is safe to do

causing personal injury. Driving on a street
or roadway without such equipment may also
be a violation of State laws and the operator
may be subject to traffic tickets and/or fines.
• For LZAS-LP Units:
A. Torque the 3/8–16 whizlock nut to 30-35
ft-lb (41-47 N-m) (Figure 19).
B. Torque the 3/8 nyloc nut to 30–35 ft-lb
(41-47 N-m).
Do Not drive a unit on a public street or
roadway.

Operation
tipping, or physical damage relative to other
tanks or to the storage cage while in transit.
WARNING
Loading a unit on a trailer or truck increases
the possibility of backward tip-over.
Backward tip-over could cause serious injury
or death.
– Place tanks so that valves, fittings, or gauges
are protected from physical damage during
transport.
• Place tank(s) in a well-ventilated trailer.
• Use extreme caution when operating a
unit on a ramp.
• Do Not store the tank(s) or machine with
tank(s) in an area where the temperature can rise
above 120°F (49°C). If the temperature exceeds
approximately 160°F (71°C), the tank will release
highly flammable propane vapor. See Preparation
in the Safety Section.
• 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 transport LPG tank(s) in the passenger
space of a vehicle.
• Do Not exceed a 15° angle between ramp
and ground or between ramp and trailer
or truck.
• Do Not transport leaking fuel tanks.
• Trailers must have appropriate markings to
transport LPG.
• Avoid sudden acceleration while driving
unit up a ramp to avoid tipping backward.
• Follow NFPA 58 and state and local regulations
for transporting LPG.
• Avoid sudden deceleration while backing
unit down a ramp to avoid tipping
backward.
Loading a Unit
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 recommended 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.
WARNING
Loading the mower onto a trailer without
strong enough or properly supported ramps
could be dangerous. The ramps could
collapse causing the unit to fall, which could
cause injury.
• Use proper ramps that are secured to the
truck or trailer.
• Keep feet and legs out from under the
unit when loading and unloading.
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.
• If necessary, use assistance when loading.
Consult the NFPA 58: Liquefied Petroleum Gas
Code for additional information regarding LPG
transportation.
• Be sure the fuel valve is closed on the tank(s).
• Place spare LPG tank(s) in a DOT approved
storage cage.
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
– Transport tanks in an upright, vertical and
secure position to minimize movement,
31
Operation
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.

Adjustments
6. Insert the height adjustment pin into the 3 inch
(7.6 cm) cutting height location.
Note: Disengage PTO, shut off engine, wait for
all moving parts to stop, engage parking brake, and
remove key before servicing, cleaning, or making any
adjustments to the unit.
7. Release the transport lock and allow the deck to
lower to the cutting height.
8. Raise the discharge deflector.
9. Measure from the level surface to the front tip of
the center blade. The measurement should read
3 inches (7.6 mm).
CAUTION
Raising the mower deck for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous. The
mechanical or hydraulic jacks may not be
enough support or may malfunction allowing
the unit to fall, which could cause injury.
Note: In most conditions, the back tips on the
side blades should be adjusted 1/4 inch (6.4 mm)
higher than the front.
Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands
or equivalent support.
Deck Leveling
1. Position the mower on a flat surface.
2. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
3. Check the tire pressure in the drive tires. Proper
inflation pressure for tires is 13 psi (90 kPa).
Adjust if necessary.

E. Using a 0.010 inch thick feeler gauge, verify
that a gap is present between the rotor and
armature face on both sides of the brake pole
as shown. (Due to the way the rotor and
armature faces wear (peaks and valleys) it is
sometimes difficult to measure the true gap.)
3. Check the condition of the wire harness leads,
connectors, and terminals. Clean or repair as
necessary.
4. Verify that 12V is present at the clutch connector
when the PTO switch is engaged.
5. Measure the gap between the rotor and armature.
If the gap is greater than .04 inch (1 mm), proceed
with the following steps:
A. Loosen both brake mounting bolts one-half
to one full turn (see Figure 35).
G011733
Note: Do Not remove the brake pole from
the field shell/armature. The brake pole has
worn to match the armature and needs to
continue to match after the shim is removed
to ensure proper brake torque.

This warranty includes the cost of parts and labor for a period of two
years and the cost of parts for one additional year. This warranty does not
cover pickup and delivery charges to and from any authorized Exmark
Service Dealer.
Owner’s Responsibilities
If your product requires warranty service it must be returned to an
authorized Exmark service dealer within the warranty period. This
warranty extends only to turf equipment operated under normal

This warranty applies to Exmark Lazer Z, Lazer Z AS X, and Vantage
turf equipment sold in the U.S. or Canada for a period of five years or
750 hours (whichever occurs first) for residential usage.
Residential usage means use of the product on the same lot as your home.
Use at more than one location is considered commercial use, and the
commercial use warranty detailed above would apply.
This warranty only includes the cost of parts and labor. For the first
warrantable service repair, Exmark will cover up to $45 for associated
pick-up and delivery charges to and from any authorized Exmark Service
Dealer. Additional transportation charges may apply, contact your Dealer
for details.
General Conditions
The sole liability of Exmark and Exmark Warranty Company with respect
