Servicing The Engine - Exmark LAZER Z XS Setup Instructions

SERVICING THE ENGINE

Service Engine Oil
Engine is shipped with oil; check oil level and
if necessary fill to the appropriate level with
oil as specified in Engine Owner's Manual.
Service Engine Coolant
Machine is shipped filled with engine coolant.
WARNING
POTENTIAL HAZARD
♦ Engine coolant is hot and pressurized.
♦ Radiator and surrounding parts are hot.
WHAT CAN HAPPEN
♦ Spray or steam from hot, pressurized liquid
in the engine cooling system and touching a
hot radiator may cause severe burns.
HOW TO AVOID THE HAZARD
♦ Allow the engine to cool completely before
removing the radiator cap or servicing any
component of the cooling system.
POTENTIAL HAZARD
♦ Engine coolant is toxic.
WHAT CAN HAPPEN
♦ Swallowing coolant can cause poisoning.
HOW TO AVOID THE HAZARD
♦ Do not swallow
♦ Keep out of reach of children and pets.
With cool engine, check that coolant level is
up to the indicator line on the overflow bottle.
If not, add 50/50 coolant mix to overflow
bottle to bring the level up to the indicator
line. Also check coolant level in radiator. Fill
it as high as possible with 50/50 coolant mix.
NOTE: Units should only be filled with Dex
Cool© extended life coolant, which can
be identified by its orange color.
CAUTION
Service the Hydraulic Oil
The machine is shipped with hydraulic oil in the
reservoir.
1. Run the machine for approximately 15 minutes
to allow any extra air to purge out of the
hydraulic system.
2. Check hydraulic reservoir and if necessary fill
the reservoir to the appropriate level with Mobil 1
15W-50 synthetic motor oil.
3. Replace hydraulic reservoir cap and tighten until
snug. Do not overtighten.
NOTE: The baffle is labeled "HOT" and "COLD".
The oil level varies with the temperature of the oil.
The "HOT" level shows the level of oil when it is at
225°F (107°C). The "COLD" level shows the level of
the oil when it is at 75°F (24°C). Fill to the
appropriate level depending upon the temperature of
the oil. For example: If the oil is about 150° F
(65°C). Fill to halfway between the "HOT" and
"COLD" levels. If the oil is at room temperature
(about 75° F (24°C)), fill only to the "COLD" level.
Unit Tracking
Operate unit with both drive levers pushed to the full
forward position. Verify that the unit tracks in a
straight line. If not, adjust motion control linkages to
correct tracking as described in Operator's Manual
Adjustment Section 4.2.13.
Engine High Idle Speed
When the throttle lever is pushed full forward, verify
that engine high idle speed is 3750 RPM plus or
minus 50 RPM. If not, adjust throttle stops on
engine linkage to obtain correct settings.
Checking Safety Interlock System
1. Check starting circuit. The starter should crank
with the parking brake engaged, PTO
disengaged, the operator in the seat, and
motion control levers moved out in the neutral
lock position.
Disengage parking brake. The starter must not
crank.
Engage parking brake and engage PTO. The
starter must not crank.
Disengage parking brake and move each drive
lever in separately. Starter must not crank.
Move both drive levers in. Starter must not
crank.
