hand.
SECTION 1 BEFORE USE
Preparing the ENGINE UNIT
The engine operating booklet supplied with your Merry Tiller gives full de-
tails of pre run and starting procedure. Please refer to this booklet.
Remember that on a new Merry Tiller there is no oil in the engine sump
nor in the chaincase.
The engine unit is a four stroke petrol engine and NO OIL should be put in
the petrol tank.
Preparing the MERRY TILLER
The transmission chaincase should re-
ceive 1 pint of S.A.E. 30 oil or oil as
specified for the engine.
To Fill: Pull out the oil filler plug. Lean the
machine onto its left side and pour in the
oil. Replace the plug.
As the chaincase has no high speed moving parts there is no possibility of
oil escaping in the form of spray, and unless the oil leaks from the case
then the level of oil in the case will remain constant. It is, however,
advisable to change the oil in the chaincase periodically but not as
regularly as the oil in the engine.
SECTION 2 USE
To Start the Engine: Refer to the Engine Booklet.
IMPORTANT
Ensure clutch is in released position before attempting to start the
engine.
(1) Pull out choke ‘A’ on carburettor. (See illustration overleaf).
(2) Push throttle lever into fast running position marked ‘F’.
(3) Pull the starter cord evenly and without jerking.
Allow the cord to return steadily avoiding 'springing back' which
can damage the starter mechanism.

Running
Once the engine starts, push choke W in by hand. Engine speed can be reduced
by pulling the throttle lever back towards 'S' and increased by pushing the lever
towards 'F'.
To Stop Engine
Move throttle lever into the 'Stop' position.
To Operate the MERRY TILLER
Select the rotors for your particular job and attach them to the rotor shaft with the
pins and spring clips provided, noting that the head of the pin should lean forward
at the top at all times to ensure that the clip remains closed.
When at the area to be cultivated, remove the transport wheels or turn them up-
side down on the hitch casting.
In Work
Ideally, when the machine is at its required working depth, then the operators po-
sition in relation to the machine should be such that the arms are almost straight
and the body virtually upright.
Whilst there is no setting position in relation to the rear skid to give a set depth it
should be set so that the length of the skid below the centre line of the machine is
approximately the depth required. On machines with Adjustable Handles further
adjustment can be made on the handles for comfort in operation.
Start the engine and set it at half throttle. Push
the rear skid into the ground and slowly raise
the clutch lever when the rotors will turn. Press
down on the handles until the machine has dug
to the depth required and then apply only suffi-
cient pressure to the handles to maintain that
depth. To dig more deeply apply more pressure
to the handles and release pressure to dig less
deeply.
Adjusting rear skid height.
FURTHER OPERATING SUGGESTIONS
To control the depth of tilling, the Merry Tiller must be operated with both the
proper throttle speed and correct up and down pressure on the handles.
Raising up means going forward, as by so doing the skid bar is allowed to come
out of the ground and the machine moves forward. Pushing down means slowing
the machine as the skid is pushed further into the soil, at the same time the ma-
chine will dig deeper. When you are first learning to use your Merry Tiller it is not
unlikely that it will tend to buck or move from side to side. This tendency will soon
be overcome with use.
To acquire the knack of letting the machine do the work without effort on the part
of the operator, we offer the following suggestions.
1 Concentrate on keeping your arms relaxed.
2 When working across a slope turn the front of the machine slightly uphill
to combat any tendency for the machine to run downhill.
3 For best results operate at reduced throttle settings when the ground is
very hard or rough.
4 Do not hurry the job proceed at a slow walk thus giving the machine
time to do its work.
5 It is advisable to re adjust the height of the rear skid to maintain the cor-
rect height of the handles, after the tiller has dug down to its required
depth.
6 The rear wheels may be used to steady the machine in work but should
never be used as a depth control.
7 It is better to release the clutch and go over the ground again if the ma-
chine starts to run away, rather than straining to hold it back which should
not be necessary.
8 Cultivate only when it is suitable to do so. Frozen or waterlogged ground,
if cultivated, can cause poor soil moisture movement.
9Cultivate at a different depth each season to stop the possibility of
'panning' in the sub soil.
SECTION 3 REGULAR MAINTENANCE
ENGINE
Refer to the engine booklet. In very dusty conditions it may be
necessary to change the oil in the engine and certainly in the air
cleaner more often than recommended.
Remember that the engine unit depends upon the flow of air over
the cylinder head and barrel for efficient cooling.
Do not allow dirt or trash to build up in the cooling fins or behind the metal cowl-
ings.
Throttle Control Adjustment
IMPORTANT
Do not attempt to adjust throttle control with the engine running.

With the throttle lever pushed fully forward i.e.
past 'Fast' running position, bend the inner
core of the throttle cable at right angles 1 5/8"
from the outer cable end. Next bend cable at
right angles again as shown below
Feed cable between petrol tank bracket and
the rear of the blower housing. Fit clamp in
place over the outer cable and lightly tighten
clamp screw. Insert inner cable through the
nut on the end of the vertical throttle link rod.
Adjust the outer cable in the clamp until ap-
proximately 1 1/4" protrudes above the top of the clamp. Pull the throttle control
lever into the 'STOP' position and, if setting is correct, the cut out mechanism on
the carburettor will operate. If the cut out does not operate, draw the outer cable
down through the clamp until the cut out operates. If the cut out operates before
the throttle lever is in the 'STOP' position push outer cable up through the clamp
to adjust. When the correct setting and operation is obtained tighten clamp screw.
Refit the air filter.
TRANSMISSION CHAINCASE
On the chaincase there is no oil level indicator as for reasons previously stated,
providing there is no oil leak, then the level will remain constant.
It is suggested that the oil in the case be changed each season as even though
there are no fast moving parts, the oil will tend to lose its lubricating properties
after a time.
CLUTCH ADJUSTMENT
The clutch should engage when the lever is raised about two thirds. When disen-
gaged the belt should be completely slack and not binding in the engine pulley.
Always use the correct belt. The Merry Tiller is supplied with a specially made belt
which has a low length tolerance variation and non rubberised casing. This gives
the correct clutch control for this machine and a rubber cased belt may cause
creeping forward of the machine due to friction.
IMPORTANT Do not attempt to adjust the clutch with the engine running.
Initial Adjustment
The clutch cable provided has a standard length with adjusting links at the lever
end. Connect the control spring to link 5 before adjusting dutch. This will give the
correct overall length of cable. Remove the belt guard by releasing the holding
knob.
Undo adjustment nut A so that the clutch wire is slack and the nut at its lowest
position.
Loosen nut B. This locks the idler arm in relation to the spindle. Adjust the idler
arm in relation to the spindle to take up some of the slack on the belt. Retighten
nut B.
Sufficiently tighten nut A to correctly set the clutch.
If it is found that the idler pulley wheel is not in line with the engine and drive pul-
leys, adjustment can be made by turning the idler arm in relation to the spindle, in
or out.
To do this it will be necessary to remove the lower guard bracket.
Further Adjustment
If it is noted that the clutch is getting slack due to possible stretching of the cable
and/or belt then this slack can be quickly taken up by turning nut A on the hook
bolt.
BELT SLIPPAGE
Always use the correct Merry Tiller belt. This can only be obtained from your deal-
er. Do not use rubber cased belts.
OIL SEALS
If oil leaks from the seals on the rotor shaft then this is a job for your dealer as
these cannot be removed without special tools.
Oil leaking at the drive shaft (top) seal can be easily overcome. First remove the
drive pulley, key and washer, and then prise out the old seal with a screwdriver.

Make sure that the keyway and shaft are free from any dirt or burrs before fitting
the new seal.
Place the seal in position and tap evenly all round until seated. Replace the wash-
er, key and pulley and make sure that the grub screw in the pulley is tight.
GENERAL HINTS
1 When storing the Merry Tiller for long periods, make sure that the engine
is stored as per the instructions.
2 Make sure that all nuts and bolts are tight before and after use.
3 Do not carry out adjustments to the engine or clutch of the machine with
the engine running.
4 It is advisable to have your machine overhauled periodically by your deal-
er.
5 The life of your machine will be greatly improved if it is kept clean.
