TILLER

OPERATION

1) Remove the garden tiller 

from its trailer/carrier. Use caution.

2) Familiarize yourself with the machine and its

controls.

3) Ensure the safety clutch control lever is in the

disengaged position. The safety clutch

control lever is located on the left handle bar.

The disengaged position of the lever is down. 

4) Remove the shaft locking pin located behind

the wheel axle. Store pin in hole provided on

left hand side of handle bar.

5) The wheel axle will now pivot. Lift up on the

handle to allow wheel axle to pivot. For

transport, keep the wheel axle forward. When

cultivating, keep the wheel axle rearward for

added stability and control. 

DO NOT transport the tiller with the wheel

axle in the rear position. 

6) Adjust depth shoe (if equipped) by removing

shaft locking collar and sliding depth shoe to

desired 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 engine

stop switch to On or

Run position. Pull

starter cord rapidly.

Repeat (if necessary)

with choke off.

8) When in position to begin garden tilling,

engage the safety clutch control lever. The

tynes will begin rotating. Wheel axle must be in

the rear position while tilling. Release the

safety clutch control lever to stop the tynes

rotating. Tyne speed is governed by engine

throttle setting.

WARNING! – KEEP HANDS AND

FEET CLEAR OF TYNES AT ALL

TIMES!

9) Do not hurry the job. Proceed slowly and allow

the machine time to do the job. When ground

is extremely hard, reduce engine speed.

WARNING! – IN CASE OF DIFFICULTY,

DISENGAGE THE SAFETY CLUTCH

CONTROL LEVER. ALL TILLING ACTION

STOPS. Press the engine "STOP" button

located on the engine.

10) Stop Engine: Release the safety clutch control

lever. Move throttle to Slow position. Set engine

stop switch to Stop or Off position. DO NOT move

choke control to Choke

or Start position to stop

engine. Backfire or

engine damage may

occur.

AFTER USE

1)

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 other

material that may have wrapped around the

tynes and rotor assembly.

5) Return wheel axle to forward position for

transport. Replace shaft locking collar.

6) Return depth shoe (if equipped) to full Up

position.

1)   Remove the stump grinder from its carrying 

vehicle or trailer. 

ALWAYS USE CAUTION

2)    Familiarize yourself with this stump grinder 

and its controls. Learn where all engine controls 

are and be prepared to stop this machine quickly 

in case of emergency.

3)

 Wear safety glasses or helmet and visor 

combination, loose fitting gloves, hearing protection, 

and steel caps boots when operating this machine. 

4)    Move choke control to Choke or Start position:

5)  Manoeuvre the stump grinder to the area where 

the stump is to be removed. This can be done by 

pushing the stump grinder using the free wheeling 

feature, or driving the machine using its own power.

6)    Position the stump grinder so that the grinding disc 

is just over the front edge of the stump.

7)  Release the spring loaded pin located behind 

 

and at the base of the handle bar, this is the  

handle release pin. Place the handle bar into the 

position that best suits to operator and secure the 

locking pin.

8)   Release the spring loaded swivel locking pin 

located on the main body right behind the engine, 

this is the main body release pin. This will allow the 

stump grinder to pivot over center.

9)   You should now be in position at the stump 

and ready to start grinding. Slowly increase the 

operating RPM of the engine to approximately 2000 

RPM and activate the clutch engagement switch 

to on. This will engage the grinding disc.

maximum RPM.

10) Slowly lower the stump grinder until the grinding disc 

comes in contact with the stump. Pivot, slew, or oscillate 

the stump grinder from left to right in a long slow 

sweeping motion. Maintain the same elevation until 

the front section of the stump has been removed, then 

move the machine forward lower the stump grinder and 

repeat the process to remove the next section. 

11)  Precision control at the stump can be achieved by 

operating the wheel control levers for each wheel 

effectively  and  efficiently.  Alternate  between  the 

two wheels by effectively crabbing, alternating the 

wheels from left to right in order to cover the entire 

width of the stump, and any surface roots.

  

NOTE: The constant build up of grinding debris 

may inhibit the stump grinder from performing 

effectively. To help insure safe, effective, and 

efficient working results, keep the working area 

raked level and free of grinding debris. ALWAYS 

USE A rAKE.
