OPERATION1) Remove the garden tiller

from its trailer/carrier. Use caution.

2) Familiarize yourself with the machine and itscontrols.

3) Ensure the safety clutch control lever is in thedisengaged position. The safety clutchcontrol lever is located on the left handle bar.The disengaged position of the lever is down.

4) Remove the shaft locking pin located behindthe wheel axle. Store pin in hole provided onleft hand side of handle bar.

5) The wheel axle will now pivot. Lift up on thehandle to allow wheel axle to pivot. Fortransport, keep the wheel axle forward. Whencultivating, keep the wheel axle rearward foradded stability and control. DO NOT transport the tiller with the wheelaxle in the rear position.

6) Adjust depth shoe (if equipped) by removingshaft locking collar and sliding depth shoe todesired position. Replace shaft locking collar.

7) Open fuel shut-off valve. Set choke control to Choke or Start position. Set throttle control to Run or Fast

position. Set enginestop switch to On orRun position. Pullstarter cord rapidly.Repeat (if necessary)with choke off.

8) When in position to begin garden tilling,engage the safety clutch control lever. Thetynes will begin rotating. Wheel axle must be inthe rear position while tilling. Release thesafety clutch control lever to stop the tynesrotating. Tyne speed is governed by enginethrottle setting.

WARNING! – KEEP HANDS ANDFEET CLEAR OF TYNES AT ALLTIMES!

9) Do not hurry the job. Proceed slowly and allowthe machine time to do the job. When groundis extremely hard, reduce engine speed.

WARNING! – IN CASE OF DIFFICULTY,DISENGAGE THE SAFETY CLUTCHCONTROLLEVER. ALL TILLING ACTIONSTOPS. Press the engine "STOP" buttonlocated on the engine.

10) Stop Engine: Release the safety clutch controllever. Move throttle to Slow position. Set enginestop switch to Stop or Off position. DO NOT movechoke control to Chokeor Start position to stopengine. Backfire orengine damage mayoccur.

AFTER USE1) Turn fuel shut off valve to the "OFF"

position.

2) Allow machine to cool down.

3) Wash mud and dirt off of the garden tiller.Ensure no water enters the carburettor.

4) Remove any weeds, wire, rope or othermaterial that may have wrapped around thetynes and rotor assembly.

5) Return wheel axle to forward position fortransport. Replace shaft locking collar.

6) Return depth shoe (if equipped) to full Upposition.

BEFORE USE

1) DO NOT allow any person operate therotary hoe without first reading andunderstanding the safety instructions andoperating instructions.

2) NEVER allow children to operate the rotary hoe.

8) ALWAYS make certain the Tyne Control Lever isset at neutral while loading and unloading therotary hoe, or moving to and away from working area.

9) NEVER run the machine in reverse while the tynesare rotating. Always move the tyne control lever to“OFF” before reversing the wheels.

11) DO NOT leave the machine unattended while theengine is running.

12) DO NOT overspeed the engine or alter the governorsettings. Excessive speed is dangerous and willshorten engine life.

13) NEVER operate the rotary hoe in anenclosed area. Engine exhaust containscarbon monoxide, an odourless andtasteless poison.

14) STOP the engine and disconnect thespark plug lead(s) and allow engine to cool before inspecting or performingmaintenance on the rotary hoe.

15)

1)

REFUELLING * Shut off the engine. DO NOT REFUEL AN ENGINE WHILE OPERATING!* Allow engine to cool. Minimum 5 minutes* USE UNLEADED FUEL ONLY. Use clean, fresh unleaded fuel.* Do not mix oil with unleaded fuel.* Do not over-fill fuel tank. Allow space for fuel expansion.

If you haveany type of physical or mental condition that maybe aggravated by strenuous work, consult withyour physician before you operate this equipment.NEVER operate the rotary hoe under the influenceof medication, alcohol or drugs.

6) DO NOT allow other persons near therotary hoe. It is up to the operator to keepbystanders and animals a minimum of 6

5) ALWAYS operate the rotary hoe on level ground only. Police the area before rotary hoeing. Remove any foreign objects in the digging area - bricks, rocks, wire and sticks. Locate and markany sprinkler heads, water pipes, gas lines, electrical and telephone cables or any other hazardeither below or above ground.

3) ALWAYS wear protective clothing when operatingthe rotary hoe. This includes, but is not limited to;safety glasses, loose fitting gloves, steel capped boots and hearing protection. NEVER wear loose fitting clothing or jewellery when operating the rotary hoe. Keep all clothing away from movingparts. Items could become caught in the machine,resulting in injury.

ALWAYS KEEP YOUR HANDS, FEET AND BODY AWAY FROM THE DIGGING ZONE WHILE ENGINE IS RUNNING.

* Do not smoke. * Allow no naked flame or hot material in refuelling area. * Use only approved fuel containers and funnels. Remember, fuel is a potential hazard .

Be sure Tyne Control Lever is set to “Neutral”while loading and unloading the rotary hoeand when moving to or from jobsite.

Ensure that all grass and weeds have been cutas low as possible.

2) If the rotary hoe is to be used in clay or hardground conditions, it is recommended to waterthe area thoroughly and allow sufficient time for earth to soften.

IGNITION: Must be in “ON” position to start. “OFF”to stop.

ENGINE: Throttle cable controls engine speed.Operate at full throttle (all the way forward).

WHEEL DRIVE CONTROL LEVER: Controls wheelspeed forward or reverse after clutch lever is engaged.

DIGGING BOOM CONTROL LEVER: Raises and lowersthe digging boom.

DIGGING CHAIN CONTROL LEVER: must be in “ON”position BEFORE clutch lever is depressed in orderto start chain in motion. Chain moves in a forwarddirection after clutch lever is engaged.

SAFETY CLUTCH LEVER/OPERATOR PRESENCE CONTROL: (At left handle grip) Activates WHEELDRIVE and DIGGING CHAIN controls when depressed.Stops all motion when released.

FORWARD/REVERSE DIGGING CHAIN CONTROL LEVER: Allows manual operation of chain in forwardor reverse rotation to dislodge objects or dig difficultterrain. (This control can be used with the clutch leverreleased.) To reverse chain, DIGGING CHAIN controlmust be in “OFF” position.

Free Wheel Hub Feature - Operation:Pull one free wheeling pin slightly, using the splitring. Rotate the pin until the 3mm (1/8”) diameter rollpin aligns with the slot in the mounting plate. Allowthe pin to slide through the slot. Repeat for the otherwheel. Roll the trencher until each pin drops into ahole in the hub. The wheel hubs are now locked.Reverse the procedure to unlock the wheels.

2)

DO NOT allow other persons near the hydraulictrencher. It is up to the operator to keepbystanders and animals a minimum of 6 metres(20ft) away from the machine while in operation.

12)

NEVER operate the hydraulic trencher in anenclosed area. Engine exhaust contains carbonmonoxide, an odourless and tasteless poison.
