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. 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 Engine Oil. Failure to add engine oil will void the product warranty.

Assembly

2 or more persons are required for assembly. • Suitable tools are required for correct

assembly. • Check all parts have been supplied and are in good condition before

commencing assembly. • Firmly secure all fasteners. • Occasionally, additional fasteners may come

supplied, however, these are not used for this machine configuration.

1. Place the depth adjustment handle (A) over the depth adjustment shaft (B). Ensure that the spring (C) is

facing outward.

2. Place a M8 washer (D) in position, and insert a M8x25 bolt (E) through the slot in the handle and screw it

in (rotate right) to the depth adjustment shaft approximately 10mm. Pull the end of the spring over the

bolt, then screw the bolt in further (there is no need to "tighten" the bolt as the spring tension should

prevent it from loosening).

3. Slide the end of the chain arm (F) onto the bar (G) at the front of the machine. Using a suitable spanner

and Allen key, back-off (rotate left) the chain tensioning bolts (F1) on either side of the chain arm so they

are as far back as possible.

4. The chain and cutting teeth assembly (H) needs to be "split' in order to be installed. Find the removable

link (H1) in the chain – it has split pins (H2) to retain the link pins (H3). Remove both split pins (do not

damage or discard them), then using a suitable pin punch and hammer, drive 1 link pin through the chain

link from the split pin side. Remove 1 nut, spring washer and bolt (H4) from the split pin side of the tooth

plate (H5), then remove the link plate (H6) from the split pin side – the chain is now split.

5. Pull the chain around the drive shaft housing underneath the machine (at this stage run the chain next to

the drive gear, and ensure that the cutting teeth are facing forward) so the free end of the chain will lie

along the top of the chain arm. Lift the chain onto the drive gear so the links engage with the drive gear

teeth. Rest the chain on the ridge running the length of the chain arm.

6. Hold the chain in position so it does not roll back around the drive gear, then pull the free end of the

chain over the idler gear at the front end of the chain arm. Bring the two ends of the chain together, then

drive the previously removed link pin through the chain link so the chain is again joined. Place the link

plate over the two link pins, then re-insert the split pins through the link pins. Bend the legs of the split

pins around so the pins cannot fall out. Re-insert the previously removed bolt through the tooth plate and

link plate, then secure it using a spring washer and nut. Use the spanners to firmly tighten (rotate right)

the nut.

7. Using a suitable spanner and Allen key, advance (rotate right)

the chain tensioning bolts (F1) on either side of the chain arm

to increase tension on the chain. Tension the chain so there is

approximately 10 to 20mm of slack in it when you pull it down

from the underside of the chain arm at its centre. When tension

is correct, tighten the nut (F2) against the welded nut (F3) on

both sides.

8. Bring the guide wheel assembly (I) into position next to the

chain arm (left side of the machine when standing behind it).

Attach the guide wheel assembly to the plate on the chain arm

side using 2 M8x25 bolts (E), 4 washers (D), 2 spring washers

(J) and 2 nuts (K). The bolts should pass through a washer,

plate, guide wheel assembly, washer, spring washer, then nut.

Note that it may be necessary to change the chain arm depth

position in order to have access to the bolt holes.

9. On the drive cover side, attach the guide wheel assembly using 2 M8x25 bolts (E), 2 washers (D) and 2

spring washers (J). The bolts should pass through a spring washer, washer, guide wheel assembly, then

into the plate. Firmly tighten (rotate right) all fasteners using the spanners.

10. Attach the front guard (L) to the mounting plate (M) above the chain arm using 2 M10x50 bolts (N),

washers (O) and spring washers (P). The bolts should pass through a spring washer, washer, front

guard, then into the plate. Firmly tighten (rotate right) the fasteners using the spanner.

11. Attach the side guard (Q) to the inside of the

soil ejection chute (R) using 4 M6x20 bolts (S),

washers (T), spring washers (U) and nuts (V). The

bolts should pass through a washer, chute, guard,

spring washer, then nut. Firmly tighten (rotate right)

the fasteners using the spanners.

When assembly is complete, the machine should look

similar to below.

Engine Oil

Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or

irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires

regular maintenance. Check the engine oil level and ensure that the oil level is at or just under the maximum

level indicator.

Always check the engine oil level before starting the engine. See Engine Oil.

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.

Adequately fill the fuel tank with the correct fuel type.

•Use non-ethanol unleaded petrol (higher RON values will provide best engine performance). Do not use

old or contaminated fuel.

To fill or top up fuel:

1. Place the machine on a flat and level surface.

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 pump away from the spillage before starting the engine.

Emergency Stopping

To stop the engine in an emergency, pull the secondary ON/OFF switch lever (A), or push the emergency

stop button (B) on the end of the handlebar. After using the button, rotate it right (clockwise) until it "pops" up.

Environmental Considerations

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.

Temperature – If the engine is being used in extremely cold or

hot environments; for example, desert or snow conditions, the

type of engine oil may need to be changed to suit environmental

temperatures. Oil thickens as the temperature decreases and

thins as temperature increases, which means that if the engine

oil is not suited to the temperature its ability to properly lubricate

the engine may be affected. Use the chart to determine the

correct engine oil.

Trencher Operation

Trenchers are high-speed, fast-cutting equipment with exposed teeth that can cause

serious or fatal injury if not used correctly or without taking proper safety

precautions. It is extremely important that you read and fully understand the information in this

section and all other safety warnings / recommendations and usage instructions before using the

equipment. • 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 trenching by machine. • Do not attempt to trench through

concrete, rock, tree roots, heavy clay or other hard or problematic surfaces. If you come across material that

cannot be trenched by the machine, use some other method to remove the material before continuing

trenching (for example, a jackhammer etc) • Do not use attachments or accessories beyond those supplied

with the machine. • Augers and auger tips are consumable parts, and are not covered under warranty.

The machine is used for digging and clearing narrow trenches, up to 600mm deep, in suitable ground

material. The machine is designed for manual operation, where the operator both holds and controls it. Note

the following:

•Adjust the throttle, which engages the trenching chain and controls its speed, only when ready to begin

trenching.

•Guide the machine as straight as possible when in use to ensure straight trenches.

•Depending on the softness of the ground material and the depth of trench, it may require several passes

at greater depths each time to complete the trench.

•Always check the trenching chain and cutting teeth before trenching. Replace any worn or damaged

components. Do not use if damaged in any way.

•If the machine is getting "stuck" during trenching, reduce depth and/or investigate other resons such as

suitablility of the ground material, obstacles etc.

•When moving the machine, disengage the wheel locks, then push down on the handlebars to raise the

trenching arm, then move the machine.

To trench:

1. Position the machine in the required location, with the front of the machine at the end of the trench – that

is, trenching is performed by moving the machine backwards.

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

3. Set the trenching arm to the required depth. It may be necessary to hold the trenching arm up by putting

weight on the handlebar.

4. Engage the wheel locks.

5. Use the throttle to increase engine speed and drive the trenching chain.

6. Holding the handlebar firmly with both hands, carefully lower the trenching arm into the ground, Allow the

cutting teeth to "dig in" to the ground material.

7. When the guide wheel contacts the ground the trench is at full depth. Put weight on the handlebar to

raise the trenching arm, then disengage the wheel locks and move the machine backwards 100 to

150mm (4 to 6").

8. Repeat steps 4 to 7 as necessary to cut the trench.

9. When finished, stop the engine and raise the trenching arm.

Adjusting Handlebar Position

1. Rotate the locking handle (A) left (anti-clockwise)

until the top section of the handle (B) can be

rotated.

2. Move the handle to the required position – where it

is comfortable for you to hold, and to raise the front

of the machine. Generally, waist height is a good

starting point.

3. Rotate the locking handle right (clockwise) until the

handlebar assembly is firmly held.

Adjusting Trench Depth

1. Pull the depth adjustment handle (C) upward so it disengages from the setting plate (D).

2. Move the handle forward to increase trench depth, or backward to reduce depth as required. Note that it

may be necessary to raise the front of the machine off the ground to allow the trenching arm to drop.

3. Release the depth adjustment handle, ensuring that the tab at its bottom is fully engaged in a slot in the

setting plate.

Using the Wheel Locks

The wheels use spring-loaded pins to lock them in position while

trenching. This is to help reduce forward "creep" caused by the digging

action of the cutting teeth.

1. Pull and hold the lever on the right handlebar (E) to disengage the

wheel locking pins.

2. Move the machine as required.

3. Release the lever. Note that there may be a small amount of

movement before the locking pins fully engage.

The wheel lock mechanism comes factory set, however, can be

adjusted, if required (for example, if the locking pins are not fully

disengaging). Before adjusting, visually inspect the wheel lock on each side of the machine – whilst looking

at the mechanism, pull the wheel lock lever (E) and check if the locking pin (F) is retracting fully from the

holes in the wheel hub (G). Release the lever – the

locking pin should enter the hole in the hub sufficiently

to prevent the wheel from rotating. If the cables require

adjustment:

•If adjustment is required for one wheel only,

loosen the lock nut (H). Rotate the adjusting

screw (I) "IN" (right / clockwise) to reduce how

much the locking pin retracts when the lever is

pulled; rotate "OUT" (left / anti-clockwise) to

increase locking pin retraction. When adjustment

is complete, tighten the lock nut.

•If adjustment is required equally for both wheels,

use spanners to loosen lock nuts (J) at the rear of

the machine – there is a second on the inside of

the plate (K). Rotate the adjusting screw (L) "IN"

(right / clockwise) to reduce how much the locking

pins retracts when the lever is pulled; rotate

"OUT" (left / anti-clockwise) to increase locking

pin retraction. When adjustment is complete,

tighten the lock nuts.

Using the Throttle

The throttle lever (F), located on the

handlebar column, is used to adjust the

engine speed, which in turn engages the

trenching chain. To adjust the throttle,

press and hold the button at the top of

the lever, rotate the lever to the required

position, then release the button.
