Water System Accumulator; Operating Precautions; Starting And Stopping The Engine; Training Period - Toro 09802 Operator's Manual

Water System Accumulator

The Hydroject accumulator contains a high pressure
nitrogen gas pre-charge. The safety system on the
aerator will disable the water injection if the accumulator
pressure is too low or too high, and will illuminate one
of the accumulator pressure lights on the operators
console.
Due to the operational requirements of the accumulator
design, the high pressure internal gas pre-charge can
bleed out during periods of inactivity. Storing the
Hydroject for extended periods of time (3 months or
longer) and/or seasonal temperature variances can
affect the accumulators ability to retain a sufficient
pre-charge and seasonal servicing (recharge) may be
required.
If one of the accumulator charge indicator lamps
illuminates, contact your authorized Toro Distributor
for accumulator maintenance services.

Operating Precautions

Follow these precautions when operating the aerator:
• Before aerating, inspect the work area for debris and
obstacles. Determine the best direction and pattern
to operate the machine. Always maintain awareness
of what lies ahead in the direction of forward travel.
• If the machine starts to vibrate abnormally, shut the
engine off. Remove the key from the ignition switch
to prevent the possibility of accidental starting.
Check the machine for damaged parts. Repair any
damage before restarting the engine and operating
the machine.
• Only use the aerator in daylight or when there is
good artificial light. Watch for holes or other hidden
hazards. Do not transport the machine close to a
sand trap, ditch, creek, or other hazard.
• To prevent roller marks, always raise the machine to
the transport position when parked on a green.
• Do not operate the water injection system
on concrete or asphalt because water jets will
permanently damage these surfaces. Do not run
over the hose as damage will occur.
• Do not operate the aerator with the roller or
injection system over the edge of anything that
could be hit, damaged, or injured by high velocity
water blasts.
• Water jets from the injection system should not
damage irrigation heads on one pass of the machine.
Do not allow multiple shots from the injection
system to hit irrigation heads as damage will occur.
• Use a good, clean, quality water supply in the
system. If good quality water is not available,
additional filtration equipment may be required. Do
not use chemicals in the water system.
• Do not allow the machine to be subject to freezing
temperatures without draining, as damage to the
system will occur.
Starting and Stopping the
Engine
1. Make sure that the wires are installed on the spark
plugs and the fuel shut-off valve is open.
2. Make sure that the parking brake is engaged.
3. Pull the choke lever out to the FULL position and
move the throttle lever to the half throttle position.
Note: When starting a warm engine, the choke
may not be necessary, but HALF throttle is.
4. Insert the key into the ignition switch and rotate it
clockwise to start the engine. Release the key when
the engine starts. Gradually return the choke lever
to the OFF position (lever all the way in) after the
engine starts and warms up.
Important: To prevent overheating of the
starter motor, do not engage the starter longer
than 30 seconds. After 30 seconds of continuous
cranking, wait 2 minutes before engaging the
starter motor again.
Important: The engine is equipped with an
oil pressure interlock switch which interrupts
the engine operation if there is not sufficient
oil pressure in the engine during starting or
operation. The engine may start but will not
continue to run due to a lack of oil pressure.
5. To stop the engine, move the throttle control
downward to the SLOW position and turn the
ignition key to OFF. Remove the ignition key.

Training Period

Before aerating with the machine, it is suggested that
you find a clear area and practice starting and stopping,
raising and lowering machine, turning, etc. This training
period will be beneficial to the operator in gaining
confidence in the performance of the aerator.
