4. Start - In this position, the starter solenoid is energized and the starter motor
cranks the engine. The switch, when released, automatically returns to the
RUN position.
NOTE: With safety shut-down incorporated, oil pressure below 7 psi and/or coolant
temperature goes above 235° F, will shut-down ignition system. Corrective action
must be taken and key recycled to restart.
When moving the handle to engage the clutch and pick up the load, do so in a
smooth manner. Moving the clutch handle too slowly will cause slippage and wear,
while moving it too fast will cause quick engagement and possible damage to the
power take-off, engine or driven equipment. The normal force required to engage
the clutch is 55 lbf (245 N) for the over-centre type and 25 lbf (110 N) for the spring
loaded type.
A final fine speed adjustment is obtained by turning the throttle control
counterclockwise to increase engine speed or clockwise to decrease engine
speed.
The throttle control adjusts engine speed. Initial engine speed adjustment is
obtained by pressing the throttle control release button while pulling the throttle
knob out to increase the engine speed or pushing it in to decrease the engine
speed.
Throttle Control (where fitted)
Safety Switch (where fitted)
A low oil pressure/high water temperature safety switch may be fitted. This
automatically shuts off the ignition when the oil pressure drops below a pre-set
value, or when the water temperature rises above a pre-set value.
Power Take-off (where fitted)
The power take-off control handle allows engagement and disengagement of the
power take-off clutch. Moving the lever towards the engine disengages the clutch
and moving the lever away from the engine engages the clutch unless otherwise
stated.
