key when engine starts.
IMPORTANT: The engine starter should not be
operated for periods longer then 30 seconds at a time. An
interval of at least two minutes should be allowed between
such cranking periods to protect the starter from overheating
and burn-out.
5. Perform test to make sure safety interlock system is
operating properly. Refer to Safety interlock system
section.
6. Allow the engine to idle a few minutes before
advancing the throttle and engaging the clutch. Press
operator’s presence control levers and rotate the H-bar
slowly forward.
7. Before stopping the engine, place the H-bar handle in
the neutral position, set neutral lock lever in the locked
position, disengage the deck clutch, and throttle back
to 1/2 throttle for a couple of minutes; then rotate
ignition key counter-clockwise to the OFF position.
Remove the key from switch before leaving the tractor.
WARNING: Never leave the machine
unattended with key in ignition switch.
Cold weather pump clutch
The Hydro WalkBehind is equipped with a pump clutch
that disengages the pump clutch belt. When the belt is
disengaged, the engine will start easier in colder temp-
eratures.
To disengage the pump clutch, pull the chain until the
tension is released from the pump drive belt and latch in the
slot. Fig. 3-5
To engage the pump clutch, with H-bar locked in
neutral, release the chain from the latching slot.
Never operate the unit with the pump clutch partially
engaged. Make sure the clutch is completely released and
the chain has slack.
Safety interlock system
The unit is equipped with a safety interlock system
consisting of the neutral lock switch, operator presence
control levers (Fig. 3-3), and deck clutch switch.
Check the safety interlock system daily, prior to
operation. This system is an important safety feature. It
should be repaired immediately if it malfunctions. The
machine incorporates two operator presence control
switches which will stop the tractor engine when the
operator releases both of the operator presence control levers
for any reason while the tractor is operating. However, if
only one operator presence control lever is released, the unit
will continue to operate. This is a safety feature designed to
prevent runaway or accidental entanglement. To inspect the
system:
1. Place the H-bar lever in the neutral position, move
neutral lock lever to the locked (rear position), and
move deck clutch switch to the disengaged (down)
position.
2. Start the engine and allow it to warm up to operating
temperature.
3. With the neutral lock lever in the unlocked (forward)
position and/or the deck clutch switch engaged (up
position), slowly release both operator presence
control levers. The engine should stop within a few
seconds.
