Before Use Checklist

Ensure that you carry out all procedures below before starting the engine or operating the equipment. All procedures described are generic in nature and slight variations between different

models may exist. Failure to follow the checklist and carry out the procedures correctly may result in

making the product warranty void.

Assembly

Prior to assembly, unpack all components and check that all items have been received.

1. With the engine upside-down, place the gearbox (A) into position over the clutch housing (B) and secure it using 4 M6x20 screws, flat and lock washers (C). Securely tighten the screws using the Allen key.

2. Attach each handle (D) to the sides of the gearbox plate (E) – the handles can be mounted to either the inside (shown) or outside edges of the plate. Ensure that the handles will angle upward when the machine is held vertically. The handle with throttle control and engine switch can be mounted on either left or right-hand side. Secure each handle using 4 M8x25 screws, spring and flat washers and nuts (F). Securely tighten the screws using the Allen key and spanner.

Air Filter

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.

Always check the air filter before starting the engine. See Air Filter.

Fuel

Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • The engine must be cool before refuelling. • Always pre-mix the fuel before

placing it in the fuel tank. • The fuel to 2-stroke engine oil mixture ratio is 25:1. Adequately fill the fuel tank with the correct fuel type.

• Use non-ethanol unleaded petrol mixed at a 25:1 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.

Petrol (Lit re) 1 2 5 10 Gas (US Gal) 0.5 1 2 3

Oil (Millilitre) 40 80 200 400 Oil (Fl. Oz) 2.56 5.12 10.24 15.36

To fill or top up fuel:

1. Place the machine in a vertical position on a flat and level surface with the fuel filler cap facing up.

2. Clean the machine around the fuel filler so that no dirt or other material enters the engine when the cap is removed.

3. Remove (rotate left) the fuel filler cap.

4. Using a funnel, carefully fill the tank with fuel. Do not fill above the top of the strainer (if equipped) or otherwise overfill the tank.

5. When finished, reinstall (rotate right) the fuel filler cap until firm. Wipe away any residual fuel from the machine. If fuel has been spilt, move the machine away from the spillage before starting the engine.

Priming the Fuel System

When an engine is new or has been completely run out of fuel it may be necessary to “prime” the fuel system before attempting to start the engine. This means removing any air from the fuel line. To prime:

1. Ensure the fuel tank is filled with fuel.

2. Press the fuel primer (A) bulb repeatedly until you feel resistance or pressure in the bulb – this indicates that it is full of fuel. Fuel may also be visible in the fuel intake tube.

Attaching the Auge r

Do not use the machine without an auger and bit attached. • The auger parts can be used in combination to extend the depth of the hole. • Do not use additional auger extension pieces beyond

those supplied with the machine.

1. Align the holes in the machine drive pin (A) and the auger bit or extension (B).

2. Insert the locking pi n (C) through the hole in the drive pin/auger and secure it using the R-clip or split pin (D). If using a split pin, bend the legs over t prevent the pin falling out.

3. Screw (rotate right) an auger bit (E) to the thread on the end of the auger. Tighten the bit firmly.

Engine Starting and Stopping

Before starting the engine, ensure that you have followed all procedures described in the

Before Use Checklist. Failure to follow the checklist and carry out the procedures

correctly may result in making the product warranty void. • Once the engine is running at sufficient

speed, the clutch will engage and begin rotating the cutting attachment. • Do NOT start the engine with the machine cutting attachment touching any object. • If the engine is new or is being re-started after

completely running out of fuel, it may be necessary to pull the starter cord several times for fuel to reach the carburettor.

Starting the Engine

1. PRIME – If necessary, "prime" the fuel system.

2. CHOKE – If the engine is cold, place the choke (A) in the "COLD" or "CLOSED" position. If the engine is warm or the ambient temperature is high, place the choke in the "RUN" or "OPEN" position.

3. IGNITION – Place the engine ON/OFF switch (B) in the "ON" ("I") position.

4. START – It is recommended to have the tool on the ground and held firmly in place when starting (for example, using your foot on the drive shaft). Slowly pull out the starter cord (C) 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.

5. WARM-UP – Allow the engine to warm-up and run smoothly. If choke is being applied, place the choke (A) in the "RUN" or "OPEN" position.

If the engine does not start, repeat step 4 onward. If the engine fails to start after several attempts, refer to

Troubleshooting.

Starting 2-Stroke Engines

Stopping the Engine

To stop the engine, release the throttle and place the engine ON/OFF switch in the "OFF" or "STOP" position.

Environmental Cons i d erations

Altitude – If the engine is being used in altitudes at or above 1500m (approximately 5000'), adjustments to

the carburettor may be required. This is because there is less oxygen in the air as altitude increases, which effectively "enriches" the ratio of fuel to air going into the engine and the higher the altitude, the richer the fuel mixture becomes. If the engine is being permanently operated at high altitude, it is recommended to have an authorized service centre make the necessary carburettor adjustments. If the engine is used occasionally at altitude (not extreme altitudes), no adjustments should be required, however, a slight decrease in engine performance can be expected.

Post Hole Digger Operation

Before use, ensure that there are no electrical cables, gas or water pipes etc or other buried

or unseen hazards in the work area. Contact the applicable utility providers for assistance. • The machine should be operated on ground that is suitable for digging. Do not attempt to dig into set concrete, rock, tree roots, or other extremely hard surfaces. • Do not use the machine without an auger and bit attached. • Augers and auger tips are consumable parts, and are not covered under warranty.

The machine is used for "drilling" holes in the ground. For example, to erect fencing etc. The machine is designed for manual operation, where the operator both holds and controls it. Note the following:

• Adjust the throttle, which controls the drilling action, only when ready to begin digging the hole.

• Hold the machine as straight as possible when in use to ensure that holes are dug vertically.

• Always check the auger flutes, cutters and bit before digging each hole. Sharpen or replace any worn or

damaged components. Do not use if damaged in any way. Below is an example of the type of condition in which an auger is not to be used:

To dig a hole:

1. Start the machine and allow it to warm up.

2. Position the machine in the required location, with the auger bit against the ground.

3. Holding the machine firmly with both hands (or having an assistant help), use the throttle to activate the

drilling action and dig the hole – once the auger starts to cut there is no need to push down on the machine. Adjust the throttle for the desired drilling rate.

4. Release the throttle – this disengages the drilling action.

5. Lift the machine and auger carefully from the hole.

Using the Throttle and Adjusti ng Drilling Speed

The throttle (A) is used to adjust the engine speed, which in turns controls speed of the drilling action. To adjust the throttle, squeeze to increase engine speed.

Maintenance

Running combustion eng ines in conf ined areas CAN KILL IN MINUTES. Engine exhaust fumes contain carbon-monoxide – a deadly gas that you cannot smell or see. NEVER run

a combustion engine in confined areas EVEN IF windows and doors are open. ONLY run combustion engines OUTDOORS and away from doors, windows and vents. • Petrol / fuel

/ gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • Do not have the engine running during inspection and maintenance unless specifically required. • The engine should be cool enough to touch before performing maintenance activities. • Some maintenance activities may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or do not have the necessary tools, experience or knowledge for – take the unit to an authorised service centre or qualified technician for servicing. • Harsh operating environments such as extreme temperatures, dust etc may necessitate more frequent maintenance. • Failure to follow the maintenance schedule, using

incorrect or non-compatible accessories or replacements parts, or general negligence may result in making the product warranty void.

To keep the machine performing at optimal efficiency, regular checks and maintenance is required. The maintenance schedule below specifies preventative maintenance checks and necessary maintenance tasks and how often they should be performed. The schedule applies to multiple engines; some engines may not include some components, so maintenance on those components is not applicable.

Maintenanc e Schedule

Use the following maintenance schedule for a list of regular maintenance tasks and how often they need to be performed. Maintenance frequency is based on average usage. Be aware of how much the machine is used and be sure to follow the schedule according to time or usage, whichever comes first.

Towards the end of this document is a form you can use for maintenance record keeping. It is recommended that you keep a reference of all maintenance.

Major Servicing and "Heavy-Duty" Usage - For engines that are subject to "heavy-duty" use,

which can be defined as being used under loads of 85% or more and / or in use more than approximately 300 hours per year (for example, generators and water pumps), more frequent "Major Service" maintenance is required. In addition to normal service requirements, and as with many smaller machine and off-road bike engines, the following parts (as applicable for petrol, diesel or 2-stroke engines) may require replacement during a major service:

• Piston rings.

• Big-end bearings.

• Small-end bearings.

• Gudgeon pin.

• Oil rings.

• Gaskets and seals.

• Valve seats. Inspection of the following items is required:

• Piston for cracks and stress fractures.

• Bore for wear requiring reconditioning.

• Full machine for broken, worn or loose parts.

Failure to follow the maintenance schedule, using incorrect or non-compatible accessories or replacements parts, or general negligence may result in making the product warranty void.

Air Filter

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 reduce performance and 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 engine breather may be connected to the air intake assembly – this may lead to a build-up of oil in the air filter over extended use and is normal. The air filter requires regular maintenance as per the maintenance schedule.

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.

• For paper filters, use compressed air to blow particles from it. The air should be blown from the engine

side of the filter.

• 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.

Removal/Installation

To remove the air filter:

1. Place the machine in an horizontal ly on a flat and level surface.

2. Unscrew the air filter cover screw (B) (rotate left) until the air filter cover (A) can be removed.

3. Pull the air filter element (C) from the air intake assembly.

To install the air filter:

1. Insert the air filter element into the air intake assembly.

2. Re-install the air filter cover and secure it with the air filter cover screw (rotate right).

Spark Plug

If the spark plug is damaged (cracked insulator, broken or eroded electrodes etc), replace it. •

Always use spark plugs of the correct "heat range" - see Specifications. 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.

Cleaning and Gap Checking

The spark plug should be checked and cleaned as per the maintenance schedule.

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 within specification (see Specifications). 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.

Removal/Installation

1. Pull the electrical lead (A) from the terminal on top of the spark plug (B).

2. If accessible, 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 (C) 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.

Fuel Strainer

A dirty or blocked fuel strainer will restrict fuel flow, which can reduce performance and be mistaken

as fuel system problems. Check the condition of the fuel strai ner before adjusting engine idle speed, where applicable. • If the fuel strainer is no longer serviceable, replace it.

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

Inspection and Cleaning

Inspect the fuel strainer for dirtiness and debris etc. Clean or replace the strainer as necessary. To clean fuel strainers:

• Wash the strainer in clean solvent.

• If possible, use compressed air to assist in removing any blockages. Blow air into the strainer from

where it connects to the tube.

Removal/Installation

To remove the fuel strainer:

1. Place the machine in a horizontal position up on a flat and level surface with the fuel filler cap facing.

2. Remove the fuel tank cap (rotate left) and empty the fuel tank (A).

3. Use a hooked object to capture the fuel intake tube (B) inside the fuel tank and gently pull it from the

tank.

4. The fuel strainer (C) is installed on the end of the tube – to remove it, twist and pull it from the end of the

tube

To install the fuel strainer:

1. Firmly push the fuel strainer onto the fuel intake tube.

2. Place the tube back inside the fuel tank – it should rest along the bottom of the tank.

Gearbox

The gearbox is used to provide the drive mechanism for the auger. The gearbox requires lubrication. To grease the gearbox: It is recommended to grease the gearbox approximately every 6 months or 100 hours use, possibly more frequently if used often. Users will require a grease gun and grease - normal automotive wheel bearing grease is suitable.

1. Attach the grease gun hose to the nipple (A) on the side of the gearbox (B).

2. Inject one squeeze of grease.

Cleaning Guidelines

Do not use solvents, chemicals or abrasives when cleaning the machine, as some surfaces may be damaged. • Wear gloves or use suitable tools to assist in cleaning – do not use bare

hands. • Clean the machine after every use to ensure best performance and longest service life.

• Use a slightly damp cloth and mild detergent for cleaning.

• Use a brush for parts that are difficult to reach.

• Ensure air vents and surfaces designed for heat dissipation are clean and free of obstructions or debris.

• For chainsaw attachments, remove the drive chain cover and clean away any sawdust, wood particles,

dirt etc from the tension adjustment mechanism, chain bar and saw chain.

• It is recommended to lightly oil cutting blades, saw chain etc after cleaning to help prevent corrosion.

• Ensure all guards and safety devices are clean and functioning correctly.

• Ensure that spring-loaded parts, such as the throttle, return to the normal position when released.

• Ensure that all control cables, levers, switches etc are clean and operate normally and smoothly.

Cleaning and Lubricating Cutters

Cutters and blades must be cleaned and lubricated after every use. Failure to do so will reduce

cutting performance and may also damage the machine. Faults or failure resulting from not

maintaining the cutting blades correctly is not covered under warranty.

• Use a non-metallic brush to remove debris from all surfaces of the cutting blades. Wipe away any debris

etc from all blade surfaces and ensure the blades are dry.

• Spray the cutting blades with spray lubricant or wipe down with light machine oil.

Engine Tuning Guideli ne s

Running combustion engines in confined areas CAN KILL IN MINUTES. Engine exhaust fumes contain carbon-monoxide – a deadly gas that you cannot smell or see. NEVER run

a combustion engine in confined areas EVEN IF windows and doors are open. ONLY run combustion engines OUTDOORS and away from doors, windows and vents. • Petrol / fuel

/ gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • Do not have the engine running during inspection and maintenance unless specifically required. • The engine should be cool enough to touch before performing maintenance activities. • Some maintenance activities may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or do not have the necessary tools, experience or knowledge for – take the unit to an authorised service centre or qualified technician for servicing. • Failure to follow the maintenance schedule, using incorrect or

non-compatible accessories or replacements parts, or general negligence may result in making the product warranty void. • Improper tuning can lead to engine failure – engine failure due to improper tuning is not covered under warranty. • If you cannot tune the engine, contact an authorised service

centre for assistance or have the machine checked by a small engine specialist. • The carburettor is supplied factory-set and should run properly. Engine tuning should be attempted only if the machine shows signs of requiring adjustment. • A tachometer is recommended for setting engine idle and full throttle speeds.

The engine must be maintained in a reasonable "state of tune" to ensure best performance and safety. If the engine is running roughly, emitting excessive smoke, not revving properly, not idling properly, showing signs of reduced power, not responding crisply to the throttle etc, it may require "tuning". Before any engine tuning:

• Service the air filter.

• Service the spark plug.

• Use fresh fuel.

2-Stroke Engine

Basic tuning for 2-stroke engines by owners is not difficult, however, care should be taken in understanding the tuning process and learning how to recognise the symptoms for when engine tuning is required and where and how to make adjustments. Note that factors such as altitude, fuel mixture, ambient temperature etc may all affect engine running characteristics. There are two basic engine conditions that determine improper tune:

• Rich - An adjustment that is too rich will cause the engine to smoke, have insufficient power, result in

additional carbon build up and may damage the engine. The proportion of fuel in the air/fuel mixture is so high that the fuel does not burn well. The partially burned mixture is expelled into the exhaust and exits the engine as smoke. Carbon build-up may affect the performance of the spark arrestor (if equipped) and cylinder ports if run for a period of time. Outside of carburettor adjustments this can also be caused by having too much oil mixed with the fuel, and/or old fuel.

• Lean - An adjustment that is too lean will also cause the engine to have insufficient power and is more

likely to damage the engine than a rich mixture. The proportion of fuel in the air/fuel mixture is so low that there is not enough fuel to burn. Lean running causes the cylinder temperature to rise, which often leads to engine seizure, and for excessive revving which may result in connecting rod bearing failure. Other causes for a lean running condition include lack of oil in the fuel mix, and when the fuel tank runs empty.

Carburettor Adjust men ts

The carburettor has 2 adjustments available:

• Idle Speed – Controls how open the throttle is when released. If idle speed is too low, the engine may

stop when the throttle is released due to a lack of air/fuel mixture. If idle speed is too high, the engine may idle at a speed that engages the clutch and cause the cutting attachment to rotate – this is a dangerous condition that should never be allowed.

• High Speed Mixture – Controls the proportion of fuel in the air/fuel mixture at working speed. If the high

speed mixture is too rich, the engine may not reach the speed necessary for maximum power, emit excessive smoke and respond poorly to throttle movement. If the high speed m ixture is too lean, the

BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG

engine may reach speeds where bearing failure and piston seizure are possible. It will also lack power and tend to run very hot.

The idle speed screw (A) and high speed mixture screw (B) are accessed from the rear of the engine.

Factory Settings

Each adjustment screw has a general "factory setting", which is measured from the adjustment screw being rotated "IN" (right / clockwise) until fully seated (but not tight). From this point, the setting is made by counting the number of full rotations of the screw "OUT" (rotate left / anti-clockwise). Factory settings are:

• Idle Speed – Approximately 5 turns out.

• High Speed Mixture – Approximately 2 turns out.

Use the factory settings as the basis for tuning. Set all adjustment screws to factory settings, then test the engine before further tuning. Use a suitable flat-blade screwdriver and ensure that the screwdriver is properly engaged with the adjustment screw before rotating.

Tuning

1. Start and allow the engine to idle until it is warmed up – tuning a cold engine will result in rich running

when the engine is warm. If the engine does not idle, use the throttle to keep the engine running ("blip" the throttle; do not run the engine continuously at high speed).

2. Adjust Idle Speed – Rotate the adjustment screw one quarter (¼) turn at a time – rotate "IN" (right /

clockwise) to increase idle speed; rotate "OUT" (left / anti-clockwise) to reduce idle speed. Set the speed so the engine idles as fast as possible without engaging the clutch. Never set the idle so the cutter attachment rotates when the throttle is released. If the engine will not idle, adjust the high speed mixture (step 3).

3. Adjust High Speed Mixture – Rotate the adjustment screw one quarter (¼) turn at a time – rotate "IN"

(right / clockwise) to lean the high speed mixture; rotate "OUT" (left / anti-clockwise) to richen high speed mixture. Rotate the screw OUT until the engine begins slowing and running roughly at full throttle. Then, rotate the adjustment screw IN – the engine should start running better. Keep rotating the screw IN until the engine reaches maximum speed. Then, rotate the screw OUT one eighth (1/8) to one quarter (¼) of a turn to richen the air/fuel mixture for engine cooling purposes.
