YOU MUST ADD ENGINE OIL BEFORE STARTING
ENGINE.
1. Move choke lever to full choke position.
2. Move throttle lever to “start”.
3. Pull starting rope out slowly one time and alloreturn
normally.
!
DANGER
4. Pull starting rope out rapidly, and allow rto turn normally.
ALWAYS KEEP HANDS AND FEET CLEAR OF
ROTATING MACHINE PARTS.
5. When engine starts, gradually move e lever to “no choke”
position and increase throttle speed.
RESTARTING A WARM ENGINE
Restarting an engine that is already warm from previous running does
not normally require use of the choke.
1. Move throttle lever to “start” position.
2. Pull starting rope out rapidly until engine starts.Allow rope to return
normally. Repeat until engine starts.

Operation
IDLE SPEED
!
WARNING
Use the “low” position on the throttle lever to reduce stress on the
engine when tilling is not being performed.Lowering the engine speed
to “idle” will help extend the life of the motor, as well as conserve fuel
and reduce the noise level of the equipment.
TEMPERATUREOFMUFFLERANDNEARBYAREAS
MAY EXCEED 150 F. AVOID THESE AREAS.
DO NOT MOVE CHOKE CONTROL TO CHOKE TO
STOP ENGINE. BACKFIRE OR ENGINE DAMAGE
MAY OCCUR.
OPERATING SPEED
For normal tilling, set the throttle lever to “fast”.
TO STOP WHEELS AND TINES AT ANY TIME, RE-
LEASE DRIVE SAFETY CONTROL LEVERS TO
NEUTRAL POSITION.
SHUTTING DOWN
To stop the engine at any time, move throttle control to the off position.
To stop wheels and tines at any time, release drive safety control
levers to neutral position.
ALWAYS RELEASE DRIVE SAFETY CONTROL
LEVERS TO NEUTRAL POSITION BEFORE
ADJUSTING THE DEPTH OF THE REGULATOR
LEVER.
TILLING
1. Adjust the depth regulator lever to desired tilling depth.
NOTE: Raise depth regulator lever up one hole at a time,
testing tiller operation after each raise. Raising depth
regulator lever too high can result in loss of control of
tiller!
!
DANGER
ENGINE AND SURROUNDING PARTS BECOME
EXTREMELY HOT DURING NORMAL USE ANDWILL
CAUSE SERIOUS BURN INJURIES IF TOUCHED
BEFORE THE ENGINE HAS COOLED.
2. Move the throttle control to fast.
3. Place the tiller in forward by pushing down on the drive safet
control lever labeled “FORWARD”--this will engage the whels a

by putting slight downward pressure on the handlebars.You
can stop the tiller by releasing the drive safety rol levers
to the neutral position.
IMPORTANT
PRACTICE OPERATING THE CONTROLS AND
TILLER WITH TINES OUT OF GROUND BEFORE
BEGINNING TO TILL. IT IS IMPORTANT THAT YOU

operate tiller with only one wheel locked.
To place wheels in free-wheel position.
1. Remove lock pin. Slide wheel inward toward machine.
2. Insert pin in axle only.
3. Wheel should turn freely on axle.
HANDLEBAR HEIGHT ADJUSTMENT
Adjust handlebar height.
The ideal height of the handlebar varies with operator height and the
depth of tilling. To adjust handlebar height: (SEE FIGURE 3)

WARNING
Tilling depth is controlled by the height of the depth regulator lever.
To adjust tilling depth. (SEE FIGURE 4)
1. Remove detent pin.
DO NOT ADJUST TILLING DEPTH UNLESS DRIVE
SAFETY CONTROL LEVERS ARE RELEASED TO
NEUTRAL POSITION.
2. Raise the depth regulator lever to position tines at chosen tilling
depth.
ALWAYS SET THE DEPTH REGULATOR LEVER IN
THE TRANSPORT POSITION BEFORE STARTING
ENGINE, THAT IS, PLACE THE DETENT PIN IN
THE HIGHEST HOLE OF THE DEPTH REGULATOR
LEVER.
3. Align hole in depth regulator lever with hole in depth regulator
bracket and replace detent pin.
Depth Regulator Lever Down = Shallower tilling. Place the
detent pin in the top hole of the depth regulator lever for shallowest
tilling.
Depth Regulator Lever Up = Deeper tilling. Place the detent
pin in the bottom hole of the depth regulator lever for deepest
tilling.
BELT TENSION ADJUSTMENT
Proper belt tension is critical to good performance. After 1/2 hour of
operation, all cables may have to be adjusted due to initial stretch.
Thereafter, check tension after every 2 hours of operation.
