Pulsa Prime engines (which have no CHOKE
marking or symbol on the control), push the
primer bulb on the side of the engine by the
carburettor, refer engine owner’s manual. (Do this
also if you have just refilled the tank after running
out of fuel). Grasp the starter grip, pull slowly
until a resistance is felt and then pull forcefully to
prevent kick-back. Repeat until the engine starts.
Do not pull the cord with a jerk or release it until
fully rewound.—When the engine starts and has
warmed up for a short time, move the control to
the desired speed. Should the engine not start
due to ‘flooding’, move the control to SLOW and
pull the starter six times to clear the flooding.
ELECTRIC START MODELS.
Please refer to the Electric Start instructions
supplied with your mower.
HINTS FOR EASY STARTING
1. Stand the mower on a paved drive or path
where the blade is clear of the grass. If
you must start on the lawn, move to an
already cut area and/or raise the cutting
height. Do not start the mower on a gravel
surface.
2. Start a warm engine with the control in the
SLOW position.
3. Keep the mower clean underneath.
HARD STARTING CHECK LIST
Look for these faults:-
FUEL 1. Insufficient fuel in tank.
2. Fuel tap shut off.
3. Stale fuel.
4. Water or dirt in fuel.
5. Blocked air vent in fuel tank cap.
IGNITION 1. Loose spark plug wire.
2. Dirty spark plug electrodes.
3. Incorrect spark plug gap.
4.Incorrect spark plug type.
OTHER 1. Choked air filter (Dirt or oil).
2. Engine control cable
mis-adjusted.
3. Cutting blade obstructed.
STOPPING
Move the engine control to stop
DRIVE CONTROLS
To engage the mower drive, simply push forward
on the SP bail arm until it meets the handle grip.
Releasing the pressure on the bail will de-clutch
the drive mechanism. Naturally you may use the
mower as a push model by gripping the handle in
the normal way.
SP DRIVE CLUTCH CABLE ADJUSTMENT
1. Confirm that the cable inner wire will move
at least 26 mm when the SP bail is moved
from the clutch disengaged (open- Fig1and
2) position to the engaged (closed-Fig3)
position against the handle. The first 13mm
moves the lever of the gearbox(Fig4) to the
engaged position and the final 13mm gives
the spring the desired 140N for the required
tension on the gearbox cones to work
properly without slipping under load. Adjust
the contour of the bail slightly if necessary to
achieve this wire stroke.
2. Wheel the mower backwards toward you
while gradually closing the SP bail, and note
the position of the bail when extra resistance
to backward movement indicates that the
drive clutch is just engaging. This extra
resistance should occur when the SP bail is
half way between open and closed (Fig 5).
Fig 5 Fig 6
3. If the engagement point is incorrect, adjust it
by rotating the thumb-wheel on the anchor
block at the top of the cable outer sleeve.
Rotating the wheel clockwise will move
the clutch engagement point nearer to the
bail closed position, and anti-clockwise will
move it toward the bail open position (Fig 6).
4. Confirm that the adjustment is correct by
re-testing the engagement point.
5. Repeat this adjustment after 150 hours use
of the mower or at any time if the mower
drive seems to be slipping.
IMPORTANT: An incorrectly adjusted clutch
cable, or using the mower with the SP bail not
fully against the handle will cause clutch slippage,
gearbox overheating and serious gearbox
damage.
CAUTION
Adjust only to provide positive drive� Excess
pressure will cause cable and belt stretch�
VARIABLE SPEED MODELS
Some models have an extra control mounted at
the side of the handle to allow the travel speed
of the mower to be varied without changing the
engine speed. This control moves into an one
of eight positions. Move the lever forward to
increase travel speed and backward to lower it.
THIS LEVER SHOULD BE MOVED ONLY WHILE
THE ENGINE IS RUNNING.
[If it is inadvertently moved back when the engine
is stationary the drive belt will slacken and slip. To
regain traction, move the lever forward with the
drive disengaged and the engine running.]
Speed changes can be made whether the mower
is moving or not.
CONTRACTOR COMMERCIAL MODELS
Self-propelled 3 Speed models.
The three speed gearbox can be changed to 1st
2nd or 3rd while the engine is running or not with
three distinct positions in the gearbox.
BLADE CONTROL LEVER
FOR BBC MODELS
To start the blade rotation, hold the inner bail arm
against the handle with your left hand. With the
engine running at full speed, push the control
lever quickly all the way forward and then return
it back to the start position. Keep holding the
bail arm against the handle. To stop the blade
rotation, simply release the bail arm. The blade
will stop quickly and the engine will continue to
run.
CAUTION
The blade has been designed to stop and start
while the engine is running.
NEVER PUT YOUR HANDS OR FEET
NEAR THE BLADES WHILE THE ENGINE
IS RUNNING EVEN IF THE BLADES HAVE
STOPPED
