As an indication coins measure the following:-
- 1p 1.58mm (0.063” ) - 2p 1.80mm (0.071” ) - 5p 1.73mm (0.067” )
- 10p 1.84mm (0.072” ) - 50p 1.84mm (0.072” ) - £1.00 3.14mm (0.124” )
Remember height of cut is effected by moisture of turf , weight of machine and the
thatch density. Different makes of machine cut at different heights when set to the
same position with the setting bar. We suggest you set it to a couple of mm above your
planned height and then come down in height by trial.
Always check height of cut/operation with the setting bar provided. Check in two
positions i.e. one at either end of the cassette. Failure to do this could result in an
uneven cut.
General Adjustments
SETTING FOR HEIGHT OF CUT
Always stop the engine before adjusting the height
of cut. Failure to do this may result in serious injury.
The length of grass after cutting depends on
the setting of the front roller in relation to the main
frame of the machine.
To set:
• Slackentheclampnutsonthefrontroller
quadrants (Item 1) [19mm spammer].
• Rotatethequadrants,raisingandloweringthe
machine. As a guide, there are notches in the
quadrant and holes in the side plate. Align these on both sides to level the machine.
XX
To check the height of cut and that the machine is level a setting bar (229524) can be used. Place the bar between the
front and rear rollers, resting the underside of the bolt head on the lip of the shear blade.
Either a ruler or pile of coins can be used to set the setting bar to the correct position. You are measuring the distance
between the bar and the underside of the button head screw (‘XX’ in the Image below).
Item 1

Simplex SP20006_REV_1
General Adjustments
SETTING THE CYLINDER
The cylinder cassette can be set either in or out
of the machine. To remove the cassette see
page 12.
To set:
• Slacken2-offlocknuts(item1)
[19mm spanner]
• Rotatenut(item2)anti-clockwisetobringthe
blade towards the cylinder.
• Checkthesettingusingthinpaperalongthe
length of the cylinder.
• Adjustuntilitcutsalongthewholelength.
• Whenset,tightenthelocknut(item1)
• Recheckadjustment.
• DO NOT set the cylinder hard to the bottom blade. This will cause excessive wear of both components and increase
fuel consumption.
HANDLEBAR ADJUSTMENT
The height of the Handle Bars can be adjusted to
suit various operators. Follow the below
instructions:-
1. Remove Bolt (Item 1) on both sides of the
machine.
2. Select the required position out of the 3
available.
3. Replace the Bolt on both sides of the machine.
GRASS BOX
If using the grass box, place the two locating tabs (projecting from the grass box support plates) into the slots on the
machine side plate. Lower the front of the box until the box support plates rest on the front cross bar of the machine.
Ensure both box support plates are properly located before proceeding.
Always disengage the cylinder drive before removing the grass box for emptying or access by reducing the engine revs
to tick over. Wait for the cutter to stop before removing.
Alwayskeepngersawayfromthecylinderwhentheengineisrunning.Stopthemachinebeforemakingany
adjustments.
Holdthegrassboxrmlyonthelipoftheapertureandplacetheotherhandonthefrontedgeofthebox.

ROLLER CLUTCH
The Primary Rear roller drive belt is shown in Fig 1.
This is a special Kevlar V belt design for clutching
applications. The Rear roller clutch pulley moves
into tension the belt via a control cable. The tension
in the cable can be adjusted as shown in Fig 1
[13mm spanner].
Under tensioning this belt will lead to slip and
cause rapid wear. Over tension will put excessive
stain on the belt and bearings.
The Secondary Rear roller drive belt is shown in Fig 2 (item1). This is a hard wearing poly-V belt. Belt tension is the single
most important factor necessary for long,
satisfactory service life of any belt drive.
Under-tensioning leads to belt slip causing rapid wear; over tensioning means excessive strain on belt and bearings.
Between these two extreme conditions is a reasonable range of tension within which the belt will operate. Belt tension can
beassessedbythe‘deection’method.
Routine Maintenance
CORRECTION CAN BE MADE BY ADJUSTMENT OF THE BELT TENSIONERS. REMOVE
THE DRIVING BELT COVER. THE BELT TENSIONERS ARE RETAINED IN A SLOTTED
HOLE ALLOWING ADJUSTMENT TO BE MADE ONCE THE HOLDING HEXAGON
HEADED BOLTS HAVE BEEN LOOSENED. WHEN ADJUSTED CORRECTLY THE
TENSIONERS SHOULD STILL ROTATE EASILY WITH FINGER PRESSURE. ENSURE THE
TENSIONER BOLTS ARE SECURE BEFORE REPLACING THE COVER.
NOTE
“Beltswillbesufcientlytensionedifthedeectionforceappliedatmidspantoproduceadeectionequalto16mmper

Inpracticaltermsthisrelatestoabout5mmofdeectionundermoderatengerpressureonthenontensionerside.
Ifttingnewbeltsitisadvisabletoobservethedrivefortherst20-30minutes.Itmaybenecessarytomakean
adjustment to compensate for the normal drop in tension during the run-in period.

NOTE
Storage
The machine should always be kept in a clean dry place, free from condensation. After use ensure that the machine is
thoroughly clean, dry and free from grass and mud. Before off season storage smear a thin layer of grease on to the
cutter blades and the shear blade.
Under no circumstances must the machine be steam cleaned as this may remove grease from the pre packed bearings.
Because of the nature of lead free petrol we recomend that if the machine is being left unused for more than 2 weeks the
carburetor is run dry. Allow the engine to run out of fuel with the fuel tap switched off.

General Lubrication
REAR ROLLER
(1-month)
A grease point is located under the belt guard on the side plate of the machine. This is to lubricate the internal spur gear
that provides drive to the rear roller. Apply one pump of grease. Do not over grease.
CONTROL LEVERS AND CABLES
(2-months)
Apply a small amount of oil to the control cables. Flow down the protective cables can be assisted by operating the lever
a few times after lubricating.
FRONT ROLLER ADJUSTERS
(2-months)
Apply a small quantity of copper grease or similar to the adjuster studs to prevent corrosion and ease adjustment.
