and ensure that the clamp bolt is secure. Ensure
that the floor sander is secure and cannot move
when being transported in a vehicle. The floor
sander is heavy. Take care when lifting and
carrying the machine.
2. To prepare the floor sander for use place the
machine on the floor and remove the cable from
the bag frame. Check that the cable is in good
condition and that all fittings are secure.
3. Lower the dust bag support frame and fit a paper
dust bag following the instructions printed on the
bag. Do not reuse or use a non standard bag. If a
cloth type bag is used ensure that it is tied securely
around the dust outlet and that the bag is in good
condition with no holes.
4. To dismantle the floor sander reverse procedure
2 to 3 above.
1. Ensure the power cable is disconnected from the
power supply.
2. Tip the floor sander upside down and rest the
machine on it's top and handles.
3. Remove the Wrench Ref.61 from the clips inside
the skirt of the floor sander situated in between
the castors and remove the Bolt Clamp Ref.59
and Washer Clamp Ref.58 from the center of the
sanding disc.
4. Select a suitable grade of abrasive disc (see
Abrasive Paper Guide on page 5).
5. Place the bolt clamp through the center of the
washer clamp and abrasive disc and carefully
thread the bolt into the sanding disc.
6. Using the wrench, tighten the bolt clamp
ensuring that the abrasive disc is centered and
the washer clamp is properly located. The bolt
should be secure but do not try to over tighten.
Heavy grit abrasive discs will seat down as you
tighten the bolt so take care to ensure the washer
CAUTION - never fit more than one
abrasive disc . If more than one abrasive
disc is fitted the setup of the sander will
be affected and the clamp bolt and
washer and sanding pad will be
damaged.
clamp is properly located. Heavy grit abrasive
discs may not lie flat on the sanding disc, this is
quite normal and the abrasive disc will flatten
immediately upon operation.
7. Do not use damaged or incorrectly sized
abrasive discs under any circumstance, damage
will result to the machine and floor.
1. Where possible remove all furniture from the
area or room. The Pacific Wolverine PF7 Edger
Sander features an efficient dust pickup, however,
some dust will escape. Protect all vulnerable
furnishings with dust sheets.
2. Remove all tacks, staples and other unwanted
fixings from the floor. Failure to do so will result
in damage to the abrasive disc and sanding disc.
3. Punch all nails below the surface of the floor
using a suitable nail punch and hammer. Any
screws used to fix boards should be counter sunk
below the surface. During sanding, any nails or
screws that become exposed must be punched or
counter sunk further.
4. Firmly fix all loose boards or blocks.
5. Remove heavy wax, grease and dirt deposits by
hand.
6. Sweep and vacuum the floor thoroughly to
remove dirt and discarded fixings.
7. Ensure good ventilation by opening windows.

switch OFF (O), release the pressure on the
switch and it will automatically return to the OFF
position.
6. Now lower the floor sander slowly forward so
that the abrasive disc comes into contact with the
floor or work piece. At the same time move the
machine in a sideways motion so when the
abrasive disc comes into contact with the work
surface it is moving to one side. This will ensure
that the sander does not dwell in one position
and damage the floor or work piece.
i. Always ensure that the floor sander is
moving when in operation and the
sanding disc is in contact with the floor.
ii. Never lift the back of the machine when
sanding.
iii. Never apply pressure to try to increase the
rate of sanding. Damage to the floor or
work piece will occur.
iv. Never bounce or drop the floor sander on
to the floor or work piece, always lower the
machine gently.
v. Never dwell in one place, move steadily at
all times.
vi. Never allow the power cable to come into
contact with the sanding disc.
7. When the dust in the dust bag reaches the ‘MAX’
line stop sanding. Switch OFF (O) and
disconnect the power cable from the power
supply and remove the paper dust bag. Turn the
top of the paper dust bag over to stop the escape
of dust and dispose of into a suitable container.

FLOOR SANDING TECHNIQUE
Pacific Rhino PFS 8 Drum Sander
Pacific Wolverine Edger Sander
Hand Sanding
- a powerful floor
sander designed for the rapid leveling and sanding of
all types of wood flooring excluding thin laminated or
veneered floors. Load the sander with abrasive
making sure that it is skin tight around the drum.
Loose sheets will tear. Place the sander on the right
hand wall (unless you are making an angled cut on
uneven floors) with about two thirds of the floor in
front of you. Start the sander with the drum off the
floor then walk forward at an even pace and ease the
drum on to the floor. As you near the end of the pass,
gradually raise the drum off the floor. Practice this
technique before turning on the sander.
Cover the same path you made on the forward cut by
pulling the machine backwards and easing the drum
to the floor as you begin the backward pass until you
reach the original starting point, then ease the drum
off the floor.
When two thirds of the floor is sanded, turn the floor
sander around and sand the remaining third in the
same way. Overlap the one third area by 0.6 to 0.9
meters (2 to 3 feet ) with the two thirds area to blend
the two areas together.
- a powerful disc
floor sander designed for sanding along the edges of
a floor without damaging the baseboards or
moldings. Also suitable for smaller areas where the
HT8-1.2 Floor Sander will not reach like stair treads
and closets load the abrasive disc making sure the
retaining bolt is tight. Start the edger with the disc off
the floor then lower the disc to the floor as you move
the sander. Work progressively moving the sander in
a sweeping motion from side to side.
- to sand difficult to reach areas
scrape and sand the floor by hand. Use a scraper to
remove old finishes, always scraping in the direction
of the grain, and then sand by hand using the same
grit abrasive as you finished with when machine
sanding. See Floor Sanding Technique diagrams on
page 5.
WARNING - never bounce the sanding
drum or dwell in one place as this will
sand dips and hollows in the floor.
FLOOR TYPES
PLANK & STRIP FLOORS
PARQUET & BLOCK FLOORS
Old floors in good condition
Uneven floors
Floors with an existing finish
- when the floor is in
good condition - no uneven edges, cupping or
crowning of planks and strips - and you want to re-
surface the floor, sanding back to new wood, start
sanding in the direction of the planks or strips - with
the wood grain. Start with a grit abrasive.
Complete the first cut with the Pacific Rhino PFS 8
Drum Sander then sand up to the baseboards and
door thresholds with the Pacific Wolverine Edger,
using a grit abrasive, blending the edges in
with the main floor area. Sweep the floor. Using a
grit abrasive, sand the main floor area
with the drum sander and then complete the floor with
the edger using a grit abrasive. Sweep the floor.
Finish sanding the main floor area with the drum floor
sander using a grit abrasive.
- when the floor is uneven sand
diagonally at 45 across the room in both directions
using the Pacific Rhino PFS 8 Drum Sander with a
coarse grit abrasive. Only make one cut on both
diagonals, this will achieve a basic level. Now
complete the floor as for a level strip or plank floor.
Use the same grit abrasive as was used on the 45 cut
for the first cut parallel to the planks or strips.
- when re-finishing a
floor remove as little of the existing surface as
possible. If the floor is badly marked and scratched
and has to be sanded back to new wood use the
Pacific Rhino PFS 8 Drum Sander and Pacific
Wolverine Edger Sander. Always try a medium grit
paper first, particularly on a diagonal cut. If 90% of
the old finish is removed and the floor is generally
leveled, you do not need to use a coarse grit abrasive.
The grain of the wood will run in a number of
directions so sand the floor in the direction of the
main source of natural light in the room. If there is no
source of natural light sand in the direction of the
longest side of the room or, if the room is square, in
the direction the furniture is laid out and how people
normally use and view the room.
This technique will help mask any imperfections in the
floor. Complete the sanding operation as detailed
for plank or strip floors.

SERVICE & ROUTINE MAINTENANCE
CAUTION - maintenance and repairs
must be carried out by authorized
personnel only. To prevent injury, always
remove the power cable from the power
supply before undertaking any work on
the machine. Do not operate this
machine unless it is fully assembled and
all guards are in place. Use Pacific Floor
Care genuine spare parts only.
General
Visual Inspection
1. Always make a list when first examining the
machine, to remind you of parts or action
needed on completion of repair/service.
2. The Pacific Wolverine PF7 Edger Sander is
subject to high speeds. All screws should be
fitted using a suitable thread lock compound.
3. On completion of any work or service on an
electrical tool or appliance statutory safety tests
must be carried out by a competent person and
recorded (see Testing for Electrical Safety page 7
and 8).
4. The needs
no lubrication during routine servicing.
5. Always ensure that the electrical supply is
disconnected before starting any routine
servicing or repair.
1. To clean the machine and remove dust, use a
vacuum cleaner to avoid damage and prevent
inhalation of dust.
2. Examine all guards and mechanical parts for
condition including the Disc Guard Ref.54 which
should be undamaged and moving freely.
3. Examine the sanding pad, a worn or damaged
pad must be replaced to maintain performance
and to avoid injury. There must be a minimum of
5/32” ‘tread depth’.
4. Examine the power cable for damage. If the
outer insulation shows the slightest of abrasions
or the inner conductors are exposed then the
cable must be replaced. The cable must not be
repaired with tape or insulation sleeve.
5. Ensure all labels are sound, readable and secure.
6. Check that the castors are sound and moving
freely. If a castor is found to be loose or damaged
then the ‘cutting’ angle must be checked and
reset as necessary (see Setting Castors page 9).
Replace damaged castors.
Pacific Wolverine PF7 Edger Sander
7. Check the condition of the Bolt-Clamp Ref.59
and clean the threads.
8. Check that the Wrench Ref.61 is in place and in
good condition.
9. If a cloth type bag is in service check the condition,
clogged dust bags or bags with holes make for
inefficient dust pickup.
1. Turn the sander upside down and rest the
machine on the handles. Check the dust skirt for
pieces of abrasive disc and build up of dust.
Clean as needed.
1. The dive gear does not require maintenance
under normal operating conditions.
1. The features
sealed for life bearings which do not require any
lubrication. In the unlikely event that a bearing
has to be replaced use a Pacific Floor Care
genuine spare part only as the grease contained
in the bearings is special. A standard bearing is
not suitable and may result in further damage.
2. Should the gearbox require service the gear
housing and gears must be cleaned thoroughly
and the gearbox refilled with grease Part No.
R011270. This is a special grease designed for
the high speed and temperatures generated
within the gear box. Under no circumstances
must a standard automotive grease be used.
Using such a grease will result in gear failure and
damage to the motor and other components.
The grease may also melt and leak from the gear
box staining the floor or work piece being
sanded.
1. The motor must be kept clean and free from
grease and dust.
2. The motor brushes must be checked regularly.
As it is necessary to remove the Cover Motor
Ref.4 during routine electrical testing, it is then a
simple matter to check the condition of the motor
brushes and avoid costly breakdowns.
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.
There is no need to remove or disconnect any
internal leads when changing the brushes, only
the small braided shunt (pigtail) is disconnected
to release the brush.

housing using a soft brush and a suitable
vacuum cleaner.
vi. Inspect the four brushes for damage or
wear and if any one brush is found to be
damaged or worn to a length of
1/2” or less then replace all four brushes.
Always replace all four brushes together.
vii. When replacing brushes ensure that each
brush moves freely in each holder and fit
the brush with the shunt (pigtail) in such a
position as to allow free movement
throughout the brush life. Ensure that
each brush shunt is connected securely
with the Screw and Washer Ref.16. (two
spare screws and washers are provided
with each pack of brushes). The brush
should be fitted so that the brush shunt
(pigtail) is at the bottom of the brush.
viii. Refit the brush springs by inserting into the
holder with the coil spring over the brush
then push in until the tag comes into
contact with the holder, slide the tag away
from the brush and release. The brush
spring will clip into position. Check the
springs and brushes for correct alignment
and free movement.
ix. Carry out electrical safety test and record
results (see Testing for Electrical Safety
page 7 and 8).
x. Finally check that all leads and cables are
clear of moving parts and will not be
trapped when refitting the cover motor.
xi. Refit the cover motor and secure with the
four Screws Ref.1.
Sanding Pad
Reasons for Removing/Replacing the Sanding Pad
Removal and Replacement of the Sanding Pad
It is very important to maintain the Pacific Wolverine
PF7 Edger Sander sanding pad in perfect condition
for score free sanding and to maximize the life of the
abrasive disc.
In normal operation the sanding pad needs little
maintenance apart from periodic trimming, however,
if the pad is worn below its minimum thickness or it is
damaged it must be replaced.
1. The sanding pad is worn below its minimum
tread thickness of 5/32”.
2. Physical damage that cannot be removed by
trimming.
3. To gain access to maintain/repair the fan, gears,
motor and bearings.
4. To remove an obstruction from the dust pickup.
1. Disconnect the edger from the power supply.
2. Turn the edger upside down and rest it on its
handles.
3. Remove the Bolt Clamp (Ref.59) and Clamp
Washer (Ref.58).
4. Using a 11/16“ hardwood dowel approximately
6" long, lock the Fan Intake (Ref.31) in position to
stop it turning by inserting the dowel through the
underside of the edger to the rear of the sanding
pad.
5. Using service tool Part No.R011730 Sanding Pad
Wrench, remove the sanding pad in a counter
clockwise direction (right hand thread). Take care
to support the edger.
Note: The sanding pad can be tight, if needed use a
soft mallet to tap the wrench to help removal.
6. Thoroughly clean the Guard Disc (Ref.54) and
refit all the Shims (Ref. 56) if removed.
7. Fit a new sanding pad and tighten using the
service tool.
CAUTION - when the sanding pad
becomes loose carefully remove it by
hand. Take care not to lose the Shims
(Ref.56) which may come away with the
sanding pad. These shims, which may
vary in quantity with a minimum of two,
are used on the Shaft Drive (Ref.47) to
pack out the sanding pad.

floor sander abrasive (120 grit) face up to a solid
flat board that is large enough to stand on and
operate the edger. Place the board on a flat even
floor and the edger on top of the board with the
pad over the abrasive. Do not fit an abrasive
disc.
CAUTION - make sure that the Clamp
Bolt (Ref.59) is secure and properly
tightened
4. Connect the edger to the power supply, stand on
the board and tip the edger back and switch 'ON'.
Carefully lower the edger so that the sanding pad
comes into contact with the abrasive. Move the
edger from side to side across the abrasive under
its own weight for a few seconds. Tip the edger
back and switch 'OFF’
5. Disconnect from the power supply and check the
condition of the sanding pad. You should witness
an even surface with no high or low spots around
the whole surface of the sanding pad in the
contact area as shown in the diagram below.
Note: Do not hold the edger in place, always keep it
moving across the abrasive sheet. Do not over trim
the sanding pad or you will reduce it's life. Do not lift
or force the edger while trimming the pad, allow the
edger to move under it's own weight. The sanding pad
minimum tread depth is 5/32“.
Reasons for Trimming the Sanding Pad
Trimming the Sanding Pad
1. As part of routine maintenance.
2. The sanding pad has been damaged.
3. The sanding pad has been replaced.
4. The sanding pad has been removed to gain
access to other components or to remove an
obstruction from the dust pick-up.
5. The castors have been replaced and/or adjusted.
1. Disconnect the edger from the electrical supply
and place the edger on a flat, smooth surface
such as a work bench. Visually check to see that
only the front of the sanding pad is in contact
with the surface it is standing on. That is, the
castors are adjusted so that the edger is ‘tipped’
forward.
2. Use a piece of paper or 0.005" feeler gauge to
check under and around the sanding pad to
confirm that only the front part of the sanding
pad is in contact with the surface it is standing on.
The correct contact area is illustrated in the
diagram below.

Adjusting the Castors
The castors are set to achieve the correct contact
area across the sanding pad as illustrated in the
diagrams above.
1. To check the castor setting place a clean sheet of
glass across the two castors and the sanding pad.
Inserting a 0.005" feeler gauge (or a sheet of
paper) between the glass and the sanding pad.
Check the correct contact area is achieved (see
diagram above - Sanding Pad Static Contact
Area)
An alternative method is to lightly dampen the
rubber sanding pad and then place the glass
sheet across the two castors and sanding pad.
Apply light pressure to the glass sheet, which will
witness the dampened area of the sanding pad
in contact with the glass.
WARNING - use toughened glass only
with a minium thickness of 1/4” with
rounded/polished edges. Take care
when handling glass. Always use suitable
gloves, eye protection and protective
clothing.
2 To adjust the castors loosen the two castor lock
nuts using the special tool Part No. R011720 and
5mm ball allen key. Adjust the castors and check
the contact area on the sanding pad. When the
contact area is correct tighten the two castor lock
nuts securely. Use a suitable thread lock
compound. Finally check the contact area is still
correct after tightening the castor lock nuts.
4. Trim the sanding pad as detailed above.
Electrical Testing.
CAUTION - testing for electrical safety
should only be undertaken by a
competent person and all results
recorded. Do not exceed 1250 volt
insulation test duration of 3 seconds.
CAUTION - when undertaking a
functional (run) test make sure the
machine is secure. Remember the
sanding disc will rotate..
1. Examine the power cable for damage. If the
outer insulation shows the slightest of abrasions
or the inner conductors are exposed then the
cable must be replaced. The cable must not be
repaired with tape or insulation sleeve.
2. Open and check the mains plug for condition,
loose connections, damaged wires, etc.
3. Remove the four Screws Ref.1 and lift off the
Cover Motor Ref.4 to check the switch,
connections, leads etc. Pay special attention to
any gaskets, ‘O’ rings and seals intended to
exclude dust from the switch and switch housing
area. These must be maintained in good
condition.
Carefully brush and vacuum clean the switch
and brush block assembly and inside the cover
motor.
4. Refit the cover motor taking care not to trap any
leads.
5. Using a piece of insulation tape or a small soft
wedge lock the bias off switch in the ‘ON’
position.
6. Use the standard test for electrical safety for a
grounded (earthed) appliance. Do not exceed
1250 volt insulation test duration of 3 seconds.
7. Record the test results.
8. Complete a functional (run) test and record
results.
