CAUTION

PLEASE READ THESE OPERATING INSTRUCTIONS CAREFULLY BEFORE

COMMENCING WORK.

We want you to obtain the best performance from this machine. If you hav e any difficulty in carr y ing out the following

instructions please contact SISIS direct or your local SISIS Territory Manager or SISIS Dealer.

OPERATING PRINCIPAL

Power from the engine is transmitted through a v ee belt clutch mechanism. One belt powers the tine reel through a

cross shaft with a final chain drive. Forward travel power is supplied through a cross shaft, spur gearing and a

differential gearbox, to the ground wheels. The depth of cut is simple to alter w ith the micro-adjuster on the handle

connecting through to the front roller frame.

CONTROLS

CAUTION

DISENGAGE THE REEL CLUTCH BEFORE STARTING THE ENGINE. RAISE THE TINE

REEL CLEAR OF THE GROUND TO PREVENT CONTACT.

E = Cut Depth Micro Adjuster
F = Tine Drive Lever

The blades must be CLEAR of the ground before adjustment
commences. The depth of cut is adjusted by varying the height
of the front rollers, using the micro adjuster. Start the engine
and allow to warm up. Engage the ground w heel and reel drives
and lower the reel using the micro adjuster until the required
amount of thatch is being removed. Always disengage the reel
drive when the machine is stationary on the green.

OPERATING INSTRUCTIONS

The Rotorake principle incorporates a series of blades rotating at
high speed in the opposite direction to that of the conventional
cylinder mower. The blades therefore cut upwards, continuousl y
taking grass fibre away from the surface rather than pushing it into
the surface of the turf. This also ensures that the machine is held
to the ground and a regular working depth maintained.

WHN WORKING ON IT.

REPLACING BLADES

THATCH REMOVAL REEL reference ARR5/TR
THATCH CONTROL REEL reference ARR5/TCR

Remove the washer and split pin at the end of the reel (opposite end to which the bearing is fitted) and strip off the knives and
rubber spacers. Replace the knives making sure that you follow the original spiral patter n, which is shown on the drawing.
Replace the washer and split pin. You w ill find it necessary t o compress t he assembly in order to replace the split pin. Use the
compression tool supplied with the machine. Replace the reel, reversing the procedure for removal.

It is not advisable to fit a few new knives. Always replace with a full set of new knives. On the thatch control reel ONLY, it is
possible to maintain ev en wear on the blades by removing the reel and replacing the blades in the reverse position on the
shaft.

ADJUSTING BELT TENSION

The ground wheel drive belt tension is adjusted by slackening the lock nuts on the cable adjuster, turning and then re-locking
adjuster under guard.

The reel drive belt tension is adjusted by slackening t he lock nut on the barrel of the pull rod. Remove split pin, turn r od to
desired position. Replace split pin and tighten lock nut.

A = Split Pin
B = Lock Nut

FRONT ROLLER ADJUSTMENT

An adjustment pivot nut is fitted at one side of the front r oller
frame assembly. This has been factory set, during assembly and
should not require further adjustment. However, if the machine
has been dismantled for maintenance purposes or mishandled at
any time, the front roller can be adjusted by placing the machine
on a level surface, with the tine reel removed and rotating the
pivot nut. The front roller is aligned correctly with the rear ground
wheels when all three are resting on the surface.

MAINTENANCE & LUBRICATION

FITTING NEW REEL DRIVE V BELTS

Ensure engine is switched off and key is removed. Remov e covers(2 top and 1 side). Slacken engine bolts and move
engine forward. Undo 2 setscrews securing the brake calliper and lift up and pull
away clear of the disc. Place some packing (cardboard is ideal) in-between the brake pads to keep them in position.
Remove belts on the bearing that is close to the disc and slacken the bolts on the bearing near the large chain pinion.
This allows the shaft to be tilted up and the belt can be removed. Fit a new belt and put shaft back into position.
Replace and tighten the bolts.

Disconnect brake rod from brake lever with the engine turned off. Put the tine reel into drive with the over centre lever.
Ensure that belt fingers on engine are not more than 2mm and not less than 1mm away from the tensioned tine drive
belt. Take the over centre lever out of drive and start engine. Put the ov er centre lever into drive and ensure that the
belts stop driving. When the over centre lever is out of driv e. If the belt stops driv ing, tur n off the engine and refit the
brake rod.

CAUTION
