STARTUP
The controls required to start and run the rototiller are located
on the engine and are the choke and throttle levers. The choke
lever is marked on one end with CHOKE and on the other with
RUN. The throttle lever is marked on one end with a STOP icon
and on the other with a FAST icon. There is also a SLOW icon
next to STOP to indicate a low throttle position.
NOTE: The 6015V does not have the stop function on the
throttle lever and instead has an ON/OFF switch located near
the recoil start.
A more detailed description of engine operation and all related
precautions and procedures can be found in the engine
manufacturer’s manual that accompanies each tiller.
COLD STARTS
1. Turn ON/OFF swith to the ON position, if equipped.
2. Move choke lever to CHOKE position.
3. Move throttle lever to half way between SLOW and FAST.
4. Pull starting rope out slowly one time and allow to return
normally.
5. Pull starting rope out rapidly, and allow rope to return
normally.
6. When engine starts, gradually move choke lever to RUN
position and move throttle lever to FAST position for tilling.
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 half way between SLOW and FAST.
2. Pull starting rope out rapidly, and allow rope to return
normally. Repeat until engine starts.
3. Adjust throttle speed to FAST position for tilling.
STOP

DANGER
ALWAYS KEEP HANDS AND FEET CLEAR OF ROTATING

SLOW FAST
IMPORTANT
IDLE SPEED
Use the SLOW position or a position between SLOW and FAST
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.
OPERATING SPEED
For tilling, set the throttle lever to FAST position.

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.
Proper tension is achieved when the spring compresses 1/4”
when drive lever is engaged.
To increase belt tension:
1. Loosen upper jam nut. (SEE FIGURE 7)
2. Tighten the lower jam nut in 1/8”increments, making sure not
to over adjust the tension.
3. Check adjustment by measuring spring compession when
drive lever is engaged. (Proper spring compression 1/4”)
4. When proper adjustment is achieved, tighten upper jam nut.
This procedure can be repeated until conduit adjustment bolts
are fully adjusted. If no more adjustment can be made, belt may
need to be replaced.

ENGINE MAINTENANCE
Refer to the engine manual included in your parts packet for
information on engine maintenance. Your engine manual
provides detailed information and a maintenance schedule for
performing the following tasks:
1. Check oil level before each use or after every 8 hours of
operation.
2. Change oil after rst 5-8 hours of operation. Change oil while
engine is warm. Rell with new oil of recommended grade.
4. Check spark plug yearly or every 100 hours of operation.
5. Service air cleaner.

7. Check engine and equipment often for loose nuts and bolts,
keep these items tightened.
CHECK OR FILL ENGINE CRANKCASE
1. Add oil according to engine manual. Do not overll. Use a
clean, high quality detergent oil. Use no special additives with
recommended oils. Do not mix oil with gasoline. Oil level
must be full. Check the oil level by removing oil ll plug. Oil
level should be up to the bottom of the ll plug opening.
2. Always check oil level before starting engine. Refer to engine
manual for capacity and type of oil to use.
CHECK TILLER TRANSMISSION GREASE
Check the grease level annually. To check the grease level:
1. Move tiller to level ground, making sure the transmission
cover plate is level.
2. Remove gear case dipstick located between the handlebar
mounts on the engine mount. Correct grease level is indicated
between the high and low levels on the dipstick.
SEE FIGURE 10
3. Replace grease level dipstick in the ller hole.
NOTE: The front wheel transmission and rear tine
transmission share a common reservoir. When you add to
the front transmission, you must wait a short period of time
for the grease to ow rearward and equalize in both front
and rear. The dipstick will read correctly on level ground for
both gear units. (Use Mystic 00, or equivalent, transmission
grease. Do not use 80W, 90W or 85-140.)
CHECK TIRE PRESSURE
Recommended tire pressure is 20 PSI. If tires do not have equal
pressure, tiller will pull to one side.
