Exmark Viking Hydro 920000 - Manual (Page 17)

Operation
The knob can be adjusted so that machine will
“track” straight ahead with the drive levers released.
PTO Engagement Control
Located on left side of control console.
To engage the blades, the knob must be pulled
toward the operator until the turnbuckle (attached
to the blade engagement idler) locks over-center. To
disengage the blades, push the knob down until the
assist arm contacts the pin on the deck.
Park brake must be disengaged before PTO is
engaged or engine will kill.
Cold Start Kit
Located on the right hand side of engine deck, below
and slightly ahead of the hydro control shield.
The cold start kit is used to ease the starting of the
unit in cold weather or when the unit has not been
operated for a period of time. The cold start kit
moves the idler pulley away from the pump belt,
releasing the tension on the belt which allows the
engine to turn over with less resistance (see Starting
the Engine section in Operation).
Pre-Start
Fill fuel tank on level ground. For best results use
only clean, fresh regular grade unleaded gasoline with
an octane rating of 87 or higher.
Important: Never use methanol, gasoline
containing methanol, gasohol containing more
than 10% ethanol, premium gasoline, or white
gas because the fuel system could be damaged.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Fill the fuel tank to the
bottom of the filler neck. The empty space in the
tank allows gasoline to expand. Overfilling may result
in fuel leakage or damage to the engine or emission
system.
Make sure you understand the controls, their
locations, their functions, and their safety
requirements.
Refer to the Maintenance section and perform all the
necessary inspection and maintenance steps.
Operating Instructions
Open the Fuel Shut-Off Valve
Rotate the valve 1/4 turn counterclockwise to turn
fuel on.
Starting the Engine
Note: Operator must have PTO disengaged and
speed control lever in neutral position when starting
the engine.
Lock drive levers in neutral and engage park brake
Note: A cold weather starting kit has been added for
ease of starting in either cold weather or when the
unit has not been run for a period of time.
• To use cold start kit:
1. Pull split ring straight out the side of the unit,
and hook the ring over the lower front hydro
control shield bolt.
2. Start engine. Refer to the following guidelines
for further starting suggestions.
• To engage pump drive (disengage cold start kit):
1. Pull chain straight out from the side of the
unit until the split ring can be removed from
the bolt.
2. Slowly release tension on chain.
1. Pull out the choke control. Place the throttle
control midway between the “Slow” and “Fast”
positions. Turn the key switch to the “Run”
position.
2. Pull recoil rope to start engine. After engine
warms up, gradually push in the choke control.
Do Not run warm engine with the choke in the
“ON” position.
Note: Kawasaki engines generally need to be
“choked” even when warm.
