Engine Starting and Operation

Before starting the engine, ensure that you have followed
all procedures described in the Before Use Checklist. The product is NOT supplied with engine oil, although traces of
oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the
engine before use – see Checking and Changing Engine Oil. Failure to add engine oil will void the product warranty.
Different models may feature variations in design; for example, some have different engine types, electric start etc. The following procedures
and images are typical to all models, however, the position or appearance of controls etc may vary. All major engine controls are identified on the
machine by way of stickers or other markings.
Manual/Pull Starting
01. PRIME – If necessary, "prime" the fuel system.
02. FUEL – Place the fuel tap (A) in the "ON" position.
03. IGNITION – Place the engine ON/OFF switch (C) or key
switch (if equipped) in the "ON" ("START") position.
For key switches, the "OFF" position allows the key
to be removed from the switch. The "ON" position is
reached when the key is rotated to the right from the
"OFF" position.
04. START – Slowly pull out the starter cord (B) until you
feel it engage with the engine, then pull it out rapidly (use both hands
if necessary). The engine should start. Allow the starter cord to rewind
slowly – do not let it "snap" back.
05. WARM-UP – Allow the engine to warm-up and run smoothly.
06. THROTTLE – Adjust the throttle control (C) for the required engine speed
and pumping requirements.
If the engine does not start, repeat step 6 onward. If the engine fails to start after
several attempts, refer to Troubleshooting.
Electric Starting
For models equipped with an electric start option, charge the battery then connect a suitable battery cable (cables may be supplied) between
the battery POSITIVE ("+") terminal and the starter solenoid POSITIVE terminal (this usually has rubber caps for the connectors). Then, connect a
battery cable between the battery NEGATIVE ("-") terminal and the starter solenoid NEGATIVE terminal.
01. Follow steps 1 to 5 as per manual/pull starting.
02. START – Turn the ignition key fully to the right to engage the starter motor. The engine should start.
03. WARM-UP – Allow the engine to warm-up and run smoothly.
04. THROTTLE – Adjust the throttle control for the required engine speed and pumping requirements.
If the engine does not start, repeat step 2 onward. If the engine fails to start after several attempts, refer to Troubleshooting.
