Fuel and Lubrication

Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • The engine must be cool before refuelling. • Do not run the engine on un-mixed fuel or fuel that is not mixed at the correct ratio. Failure to use the correct fuel type / mixture may permanently damage the engine and void product warranty. • Mix the fuel thoroughly before adding to the unit. • Some conventional petrol blends use oxygenates such as alcohol or other compounds to meet emission requirements. This engine is designed to operate satisfactorily on any petrol for automotive use including these types of blends.

Adequately fill the fuel tank with the correct fuel type.

- Use non-ethanol unleaded mixed at a 40:1 ratio with 2-stroke engine oil (higher RON values and good quality 2-stroke oil will provide best engine performance). Do not use old or contaminated fuel/oil. Fuel/oil mix ratio examples are shown below.

Engine Idle Adjustment

In some cases due to operating conditions (altitude, temperature etc.) the engine may not idle reliably after fully warming up. If this occurs, a slight adjustment to the idle speed may be required.

1. Locate the carburettor idle adjustment screw (G).
2. Use a Phillips or slotted-screwdriver to rotate the idle adjustment screw right (clockwise) 1/4 turn.
3. Check the idle. If the engine still does not idle reliably, repeat step 2. If the engine still not idle or further adjustments are necessary, take the machine to an authorised service centre.

User Guide

Starting the Engine

Video Tutorial:

Starting 2-Stroke Engines

Always pull the starter cord straight out. Pulling it at an angle will cause it to rub against the machine, which may damage it and wear it more quickly. • Allow the starter cord to retract slowly – do not let it "snap" back. This could cause the rope to snag or fray and also damage the starter assembly.

1. Place the engine ON / OFF switch (A) in the "ON" ("I") position.
2. If the unit is new, has just been re-fuelled or has not been used for a period of time, press the fuel primer bulb (B) repeatedly until it feels firm.
3. Place the choke (C) in the most suitable position, depending on engine temperature and ambient temperature. For cold engines, use 🔒 "COLD" and for hot engines, use 🔒 "RUN".
4. With the unit on the ground, hold the top handle and step on the bottom frame to steady it. To start the engine, slowly pull the starter cord until you feel it engage the engine, then pull rapidly. Repeat until the engine starts. If the engine does not start after more than 4 attempts, reduce the amount of choke and attempt to start the engine.
5. Once the engine has started, allow it to warm up, gradually reducing choke until it is in the "RUN" position before using the machine.

Stopping the Engine

Emergency Stopping Procedure

Place the engine ON / OFF switch in the "OFF" position.

Normal Stopping Method

For normal stopping, release the trigger and allow the engine to return to idling speed. Then place the engine ON / OFF switch in the "OFF" position.

Operating the Blower

Always wear a face shield when operating the machine. • Maintain a distance of at least 20m (60') between the operator and any bystanders, animals etc. • Never blow debris in the direction of bystanders.

With the engine running, press and hold the lock-out button (A) button, then squeeze the throttle (B) to activate the blower and adjust engine speed.

The velocity of the air stream is dependent on engine speed – use the throttle to adjust engine speed / air velocity as required when using the machine.

• Stand at a distance away from debris that will easily allow you to control its direction as it is blown.
  • Use rakes and brooms to loosen debris before blowing. In dusty conditions, slightly dampen surfaces.

Maintenance

Checking, Cleaning or Replacing the Air Filter

WARNING! Operating the machine without a functional air filter may cause severe engine damage and will void any warranty. • A dirty or oil saturated air filter will restrict air flow, which can be mistaken as fuel system problems. Check the condition of the air filter before adjusting engine idle speed, where applicable. • If the air filter is damaged (torn, broken, disintegrating), replace it.

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal damage to it. The air filter requires regular maintenance as per the maintenance schedule.

Air Filter Inspection and Cleaning

Inspect the air filter for dirtiness and debris, damage etc. Clean or replace the filter element as necessary. To clean air filters:

• For foam filters, wash the filter in warm water and mild detergent, then rinse and allow to dry.
• Clean all other air filter assembly components using water and mild detergent, then dry them.
• For foam filters, place a few drops of clean engine oil on the filter then squeeze it a few times to spread the oil through the filter material and remove any excess oil.

Air Filter Removal/Installation

1. Loosen the knob (A) holding the air filter cover in place.
2. Remove the air filter cover (B) and lift the filter (C) from the air intake assembly.

Cleaning the Fuel Filter

Remove fuel from the tank and store it in an approved container before starting this procedure.

1. Open the fuel cap to slowly release any pressure in the fuel tank, then remove the cap.
2. Use a piece of wire to hook the fuel tube/filter (C), then pull the filter from the tank.
3. Remove the fuel filter from the tube with a twisting motion.
4. Ensure that the fuel tank vent (A) is clean. Clean the fuel filter of obstructions etc using petrol or solvent.

Never operate the blower without the fuel filter. Internal damage could result.

Spark Plug

If the spark plug is damaged (cracked insulator, broken or eroded electrodes etc), replace it. • Always use spark plugs of the same type as originally supplied.

The spark plug is used to ignite the air/fuel mixture inside the engine. The spark plug has electrodes on one end and an electrical terminal on the other. The spark plug requires regular maintenance.

Spark Plug Cleaning and Gap Checking

The spark plug should be checked and cleaned approximately every 6 months.

1. Remove any carbon deposits on the spark plug (A) electrodes (B) with a wire brush.
2. Clean the spark plug threads and the electrical terminal (C) on the top.

To check and adjust the spark plug "gap":

1. Use "feeler" or "thickness" gauges (X) to measure the existing gap. The gauge must drag a little when being slid between the electrodes (2) – this means the measurement is fairly accurate.
2. Adjust the gap to 0.6mm (0.025"). If the gap needs to be reduced, gently tap the electrode as required. If the gap needs to be increased, use pliers to gently pull the electrode as required.
3. Measure the gap again and ensure it is within the specified range before re-installing the spark plug.

Spark Plug Removal/Installation

1. Pull the electrical lead from the terminal on top of the spark plug.
2. Clean the area around the spark plug so that no dirt or other material can enter the engine when the spark plug is removed.
3. Use the spark plug tool to remove the spark plug (rotate left).

To re-install the spark plug:

1. Place the spark plug in its hole and screw it in (rotate right) until "finger tight".
2. Use the spark plug tool to tighten the spark plug approximately one quarter turn (do not over-tighten).
3. Place the electrical lead over the spark plug terminal and push it down so that it connects firmly with the terminal

Storage

Failure to follow these steps may cause varnish to form in the carburettor. If this happens then the carburettor will have difficulty starting.

1. Perform all the general maintenance recommended in the maintenance section of your user manual.
2. Clean the outside surface of the blower.
3. Drain fuel from the fuel tank.
4. After the fuel is drained, start the engine.
5. Run at engine at idle until it stops. This purges the carburettor of fuel.
6. Allow the engine to cool.
7. Remove the spark plug.
8. Pour one teaspoon of clean 2-stroke oil into the combustion chamber. Pull the starter cord slowly several times to coat internal components. Re-install the spark plug.
9. Store the machine in a cool, dry place away from sources of ignition (oil burner, water heater etc).

Removing from Storage

1. Remove the spark plug.
2. Pull the starter cord briskly several time to clear excess oil from the combustion chamber.
3. Re-install the spark plug.
