attempt to tow the vehicle.
When transporting the vehicle, it shall be secured to the transporter by means of suitable
straps as follows:
Front Wheels............................One Strap per Wheel to a REARWARD lashing point.
Rear Wheels.............................One Strap per Wheel to a FORWARD lashing point.
Front of Body...........................One Strap each end of Front Bumper to a FORWARD lashing
point.
Rear of Body............................One Strap over each Rear Spring Hanger to an OPPOSITE
REARWARD lashing point.
IDENTIFICATION PLATES

TILTING THE CAB
CAUTION
Before tilting the cab, ensure that there is sufficient space to do so and
that all loose items are safely stowed.
1. Operate the cab-locking lever (located between the seats) by
moving it through approximately180°(see Fig. 2).
2. Close the cab door and raise the cab safety latch, simultaneously
lifting the rear of the cab until it reaches its maximum tilt position.
3. Deploy the cab prop, locating it in its retaining pocket on the
chassis rail.
CAUTION
Before lowering the cab, ensure that area below it is clear of any items
or equipment used while the cab was in the raised position.
4. Lower the cab and engage the locking lever.
WARNING
BEFORE DRIVING THE VEHICLE, ENSURE THAT THE CAB LOCKING LEVER IS
FULLY ENGAGED IN THE LOCKED POSITION.

KEY MAINTENANCE PROCEDURES
CLEANING THE SUCTION FAN
WARNINGS: FAILURE TO COMPLY COULD RESULT IN SERIOUS INJURY.
1. BEFORE WORKING ON THE MACHINE POSITION IT ON FIRM, LEVEL
GROUND, APPLY HANDBRAKE, STOP ENGINE & REMOVE IGNITION KEY.
2. ALWAYS USE THE HOPPER PROP TO SUPPORT A RAISED HOPPER.
3. THE FAN IS AN EXTREMELY HEAVY ROTATING MASS. NEVER ATTEMPT
TO SLOW OR STOP ITS ROTATION BY USING THE HANDS OR BY
INSERTING ANY ITEM INTO THE FAN CHAMBER, EVEN AT LOW SPEEDS.
4. BEFORE REMOVING THE SUCTION FAN ACCESS PANELS, ENSURE THAT
THE ENGINE IS OFF AND THAT THE IGNITION KEY HAS BEEN REMOVED.
5. ALWAYS WEAR SUITABLE EYE PROTECTION WHEN USING THE HAND
LANCE.
1. Raise the hopper and deploy the hopper prop.
2. Switch off the engine and remove the ignition keys.
3. Remove the outer inspection cover from the hopper and the inner
cover from the fan housing to expose the fan (Refer to Fig. 3).
4. Using high-pressure water from the jetting lance and the special
scraper, as necessary, thoroughly clean the fan. Pay particular
attention to the inside curve of each impellor blade and to the
area around the fan hub.
5. Refit the inspection covers and lower the hopper.
WARNING:
LOOSE PARTICLES FROM THE CLEANING PROCESS CAN BE EJECTED FROM
THE FAN CASING VIA THE HOPPER COVER WHEN THE FAN IS RESTARTED.
ENSURE THAT THE AREA AROUND THE MACHINE IS CLEAR BEFORE
RESTARTING.

SUCTION NOZZLE CLEARANCES
inspect the suction nozzle flaps to verify that they are in good condition
and do not exhibit excessive wear. Adjust as necessary to achieve the
correct flap to ground clearances (Refer to Fig. 4).
NOTE:
These clearances are based on the factory set-up. For some operating
conditions, it might be found that, alternative clearances are preferred.
SETTING UP THE BRUSHES & SKIRTS
Maintaining an effective brush set-up is essential to good sweeping
performance,italsodetermine.Thefollowinginstructionsarebasedonthe
factory settings, which produce excellent results in virtually all conditions.
It should be remembered, however, that there is no substitute for
experience and if it is found that, for a specific sweeping job, an
alternative set-up is more effective, this may be adopted when necessary.
SIDE BRUSH
1. The sidebrushshouldbeangled
so that, when deployed, about
33% (120°) of the outer/leading
edge of its circumference is in
contact with the road surface.
2. The rubber skirt adjacent to the
side brush collects / positions
material in the path of the
suction nozzle. Condition and
adjustment are very important.
Position the skirt so that it is just
clear of the ground.

FRONT BRUSHES
1. There are two sweeping configurations with the Front Brushes.
(a)When both brushes are lowered straight down onto the road.
(b)When the curb-side brush is extended outwards to the gully.
On dual sweep machines, both brushes can be extended.
2. On single sweep machines, front brush tilt-angle differs from side to
side. For general sweeping duties, a greater proportion of the
outward-extending brush is in contact with the road surface.
3. To set the correct tilt angles, adjust the Top Link and/or swivel the
Motor Plate, to obtain a satisfactory setting as follows:
4. Extending Brush. Set the brush so that about 40% (150°) of its
circumference, at the outer/leading edge, is in contact with the
road surface, when the brush is in the extended position.
5. Non-extending Brush. Adjust so that about 33% (120°) of its
circumference, at the outer/leading edge, is in contact with the
road surface.

FRONT BRUSHES (Continued)
Dual Sweep Machines
1. Adjust the Top Link and/or Motor Bracket of each brush, until about
40% or 150° of its circumference, at the outer/leading edge, is in
contact with the road surface.
CAUTION:
An incorrect front brush set-up affects not only sweeping efficiency, but
can also greatly influence the rate of brush wear.
REMOVING / REFITTING THE BRUSH HEADS
The Scarab Minor Euro 3 is fitted
with quick-release brush hubs.
These hubs incorporate slotted
holes. Brush removal is
accomplished by loosening the
four flange nuts and rotating the
brush, until the nuts align with the
holes. The brush can then be
taken off and/or refitted without
removing the nuts from the brush
bolts. All Scarab supplied
replacement brushes now have
captive bolts and are supplied
with new flange nuts.
CAUTION:
Care should be taken to ensure that when fitting/refitting brushes they
are correctly positioned on the hubs, in accordance with the illustrated
alignments (see Fig. 7).
FLUID LEVELS
For coolant and hydraulic filler points refer to Fig. 8.
The brake and screen-wash reservoirs are in the cab. Access to the brake
fluid reservoir is gained via a flap on top of the dash panel.
For engine oil filler and dipstick refer to Fig. 9.

Original Issue - 19 August 2003 Operator’s Manual Page 17
LIMITATIONS OF USE
The Scarab Minor is classed as an Urban/Precinct Road Sweeper and, as
such, is intended only for operation in the sweeping and associated roles
for which it has been expressly designed.
OPERATING PROCEDURE - DRIVE MODE
1. Ensure that the Forward/Reverse lever is in the NEUTRAL position
and that the hand brake is applied.
2. Start the engine and select Drive Mode (0) on the Key Switch.
3. Select FORWARD or REVERSE on the Forward/Reverse lever.
4. Release the handbrake and slowly depress the throttle pedal to
move the vehicle in the appropriate direction of travel.
NOTE:
In Drive Mode, the vehicle is controlled, by means of the throttle and brake
pedals, in a similar manner to a vehicle fitted with automatic transmission.
Releasing the throttle pedal at normal road speeds produces a conventional
automotive-style deceleration/over-run.
