support the PFS 8 with the rubber wedge supplied in
the Owners Pack. Place the wedge on the floor and
roll the Rhino PFS 8 onto the wedge in the centre of the
machine until it comes to a stop to prevent the drum
rubber developing a flat spot.

1.

Check that power supply is disconnected. Tilt the
machine back and rest the handle on the floor.
Open the drum guard and remove the abrasive
belt if fitted. Inspect the condition of the drum
rubber. A damaged or worn drum rubber must
be replaced to maintain machine performance.
A damaged or worn drum rubber can result in
poor sanding performance with subsequent
damage to the floor surface and can be
dangerous in operation.

If the machine moves from side to side when
sanding or you are experiencing inconsistent
sanding performance this can indicate a worn or
damaged drum rubber. This is caused because
the drum rubber is not gripping the sanding belt.

2.

To replace the drum rubber contact your local
Service Agent.

Pacific Floor Care operate a

simple exchange program to replace Rhino PFS
8 Sanding Drums.

Please contact your local

service agent for information, service levels and
pricing.

3. Check the condition of the Abrasive Guides

(Ref.142). It is very important that the Abrasive
Guides are maintained in good condition. The
Abrasive Guides ensure that the abrasive belt
runs evenly and centred on the sanding drum.
Worn Abrasive Guides will cause wear to the
drum rubber, result in poor sanding
performance and cause damage to the machine
and floor surface.

Worn guides will also

damage the abrasive belt and may cause it to
tear.

The Abrasive Guides should not be worn by more
than 1/8” (3mm). The thickness from new is 1/4”
(7mm).

4.

When fitting new Abrasives Guides or when
replacing the Drum Guard (Ref. 35) ensure that
the correct gap is maintained between the edge
of th sanding drum and the Abrasive Guides .

Remove abrasive belt if fitted, using the Spacer
Guide Abrasive (Ref.143) adjust the gap
between the Abrasive Guide and the edge of the
sanding drum on both sides of the drum as
follows;

8in wide abrasive - gap 3/32 to 5/32in

200mm wide abrasive - gap 1.5 to 2.5mm

The Spacer Abrasive Guide are of various
thicknesses.

User the thicker guides first and

adjust the gap using the thinner spacers if

required.

5.

Check the condition of the rear wheels (Rollers
Ref.61). The wheels must be free from dirt and
rotate freely. Check the condition of the Shaft
Roller Ref.60, use a straight edge to make sure
the shaft is not bent.

1.

The motor must be kept free from grease and
dust. DO NOT use high pressure air to blow the
motor clean. Use a vacuum and soft brush to
clean the motor and brush block assembly.

2.

The motor brushes must be checked regularly,
inspect the brushes every three months or every
300 hours from new and then every 100 hours of
use thereafter.

3.

Replace ALL FOUR motor brushes when any one
brush has worn to 1/2” or less in length. Brushes
MUST slide freely in the brush holders.

When any one motor brush is worn down to the
ware indicator inspect the brushes ever 100hrs.
Replace all four motor brushes when any ONE
(1) motor brush is worn down to the minimum
brush length as indicated by the bottom of the
triangle stamped on the motor brush.

4.

To inspect and replace motor Brushes Ref.104,
with the brush block assembly removed.

i.

Remove the three Screws Ref.82 and

remove the Wall End Guard Ref.84 to
expose the motor brush assembly.

ii.

Remove the four retaining Screws Ref.31

from the Shield Wall End Ref.30, insert two
of the screws into the ‘jacking holes’
situated adjacent to the countersunk
retaining holes.

iii.

Carefully tighten these screws until the

shield wall end is jacked clear of the outer
casting. Withdraw the shield-wall end.

iv.

With the brush block assembly complete

and the connecting leads still attached.
You will note that as the brush block
assembly is withdrawn the brushes spring
towards the center and often the brush
springs fall clear as the brushes are no
longer at a height to retain them. Take care
not to lose any springs.

v.

To remove a brush spring with a brush in

the operating position push the brush
spring down and towards the brush and lift
out.

vi.

Using a cross recess screwdriver remove

the four brush shunt (pigtail) retaining
Screws Ref.105 and lock Washers Ref.100.
