Assembly and Transport
To help with the following instructions please refer to
the parts drawings on page 12 and 13
1. The HT8-1.2 breaks down into three component
parts, the main body, handle assembly and dust
tube for easy handling and transport. To
assemble loosen the Clamp Bracket Ref.21 and
slide the handle assembly into the Handle
Bracket Ref.51. Adjust the height of the handle
so that your arms are slightly bent when standing
upright behind the machine. This will provide
you with maximum control in operation. Tighten
the clamp bracket firmly. Always ensure that the
clamp bracket is tight, check periodically during
use.
2. Connect the Cable Handle Ref.20 to the Body
Twist Lock Ref.24 at the rear right hand side of the
floor sander body. Align the plug with the pins,
push in and twist clockwise to lock.
3. Slide the Exhaust Tube Ref.59 into the Exhaust
Bracket Ref.56 and push fully home.
4. Fit a paper dust bag following the instructions
printed on the bag. If a cloth bag is used ensure
that it is tied securely around the dust tube neck
and that the bag is in good condition with no
holes.
5. To prepare the floor sander for use place the
machine on the floor and remove the main cable
from it's storage position on the handle
assembly. Check that the cable is in good
condition and that all fittings are secure.
6. To dismantle the floor sander reverse procedure
1 to 5 above.
7. Always 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.
Installing Abrasive Belt
1. Ensure the power cable is disconnected from the
power supply.
2. Tip the floor sander back so that it rests on the
rubber buffer on the rear of the handle.
3. Lift the Drum Guard Ref.35 to expose the
sanding drum.
4 belt. Select a suitable grade of abrasive (see
Abrasive Paper Guide on page ).7 Check
direction arrows printed on inside of the abrasive
belt. The arrows must point clockwise in the same

Take care not to trap fingers around the main
frame and dust shoe.
6. Lower the drum guard and stand the machine
up. The floor sander is now ready for use.
Note: Use Hiretech genuine floor sander abrasives
for the best sanding performance and finish. They
will also reduce the risk of tearing due to poor fit
which is a common problem with generic and non
standard abrasives.
PREPARATION
1. Where possible remove all furniture from the
area or room. The HT8-1.2 Floor Sander
features an efficient dust pickup, however, some
dust will escape.
2. Remove all tacks, staples and other unwanted
fixings from the floor. Failure to do so will result
in damage to the abrasive paper and sanding
drum.
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.
OPERATION
DANGER - never operate the machine
without an abrasive belt installed on the
sanding drum.
1. Move the floor sander to the location of your
work.
2. Connect the power cable to a suitable power
supply ideally located behind or to one side of
the machine and work area.
3. Wear a dust mask and ear protection.
4. Hold both handles with the main cable held in a
small loop in the left hand and then passed over
the left shoulder.
5. Apply light downwards pressure on the handles
to tip the floor sander back to raise the sanding
drum off the floor. Switch on by pushing the
ON/OFF switch to the ‘I’ position.
CAUTION - the HT8-1.2 Floor Sander is a
powerful machine. Always ensure that
you have a firm grip before switching on.
6. Now move the floor sander slowly forward and
at the same time release the pressure on the
handles to gently lower it so that the sanding
drum comes into contact with the floor.
7. Guide the floor sander in a straight line at a slow
walking pace. Do not force or hold the floor
sander back. Allow the machine to do the work
and always move at an even pace.
8. At the end of the pass while still moving forward
tilt the floor sander back so that the sanding
drum comes clear of the floor. Now moving
backwards lower the floor sander again and pull
it backwards over the area just sanded moving at
a steadily even pace. Take care to ensure that
the power cable is kept clear of the sanding drum
at all times. At the end of the sanding pass and
while still moving backwards tilt the floor sander
back so once again the sanding drum comes
clear of the floor.
Move the machine over so that it overlaps the
area just sanded by 3" (75mm) and start to sand
3
the next pass repeating the above technique.
CAUTION - to prevent damage to the
floor surface, work piece or machine
follow these rules.
i. Always ensure that the floor sander is
moving when in operation and the
sanding drum 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 and
machine will occur.
iv. Never bounce or drop the floor sander on
to the floor. 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 drum.
9. When the dust in the dust bag reaches the ‘MAX’
line stop sanding. 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. Dampen the dust bag down
with water to reduce the risk of spontaneous
combustion. Never reuse the paper dust bag or
empty it or dispose of it into a fire. If a cloth bag
is used empty into a suitable container being
careful to contain the dust. Do not dispose of the
contents into a fire.
10. Fit a new paper dust bag or refit the cloth bag.
Reconnect the floor sander to the power supply
and continue sanding.
11. When taking a break from work disconnect the
power cable from the supply, remove and
dispose of the paper dust bag, or empty the cloth
bag as detailed in 8. above. Never leave the
floor sander unattended with the dust bag in
place containing dust.
12. On completion disconnect the power cable from
the supply. Remove and dispose of the paper
dust bag, or empty the cloth bag as detailed in 8.
above. Stow the cable on the handle assembly
and if required dismantle for transportation.
Carry out maintenance as recommended in
Maintenance and Servicing.
DANGER - never leave the floor sander
unattended with dust in the dust bag.
Always remove the dust bag and dispose
of into a suitable container.

FLOOR SANDING TECHNIQUE
HT8-1.2 Floor Sander (Drum) - 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.
WARNING - never bounce the sanding
drum or dwell in one place as this will
sand dips and hollows in the floor.
HT7-2 Disc Floor Sander (Edger) - 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.
HTF-2 Floor Sander (Orbital) - a orbital action
floor sander designed for re-finishing, sanding
between coats of varnish and re-surfacing floors in
good condition. load the abrasive sheet, pad or strip.
Start the sander, move immediately and sand in the
direction of the grain using the same technique as the
drum floor sander. For difficult to reach areas use the
disc floor sander with a fine grit abrasive, or sand by
hand.
Hand Sanding - 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.
FLOOR TYPES
PLANK & STRIP FLOORS
Old floors in good condition - 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 medium grit abrasive.
Complete the first cut with the HT8-1.2 Floor Sander
then sand up to the baseboards and door thresholds
with the HT7-2 Disc Floor Sander, using a medium
grit abrasive, blending the edges in with the main
floor area. Sweep the floor. Using a medium/fine grit
abrasive, sand the main floor area with the drum
sander and then complete the floor with the edger
using a fine grit abrasive. Sweep the floor. Finish
sanding the main floor area with the drum floor
sander using a fine grit abrasive. If the floor is in
particularly good condition (level with no deep
scratches or blemishes) you may re-surface the floor
using the HTF-2 Floor Sander, however, as the
sanding action of this machine is less aggressive than
the HT81.2 Floor Sander the job will take more time.
Uneven floors - when the floor is uneven sand
diagonally at 45 across the room in both directions
o
using the HT8-1.2 Floor 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
o
parallel to the planks or strips.
Floors with an existing finish - when re-finishing a
floor remove as little of the existing surface as
possible. If the old finish is worn and the floor is
generally in good condition use the HTF-2 Floor
Sander with Hiretech abrasive pads and strips which
have been especially designed for re-finishing floors.
These will maintain the integrity of any stain used to
colour the wood and prepare the surface for a new
coat of finish. If the floor is badly marked and
scratched and has to be sanded back to new wood
use the HT8-1.2 Floor Sander and HT7-2 Disc Floor
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.
VENEERED, LAMINATED & THINNER FLOORS
Use the HTF-2 Floor Sander for veneered and
laminated floors or thinner floors that may have been
subjected to repeated sanding. The HTF-2 will
remove old surface finishes and prepare the floor for
re-finishing. Sand the floor using the same method
as a strip, plank, or parquet floor. If the floor has
deeper scratches or marks these should be sanded
4

5
out by hand and blended in with the main floor. To
check the wood depth in the floor remove a
baseboard or molding from around the edge of the
floor. This should provide access to the edge of the
floor for inspection.
PARQUET & BLOCK FLOORS
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.
BETWEEN COATS OF FINISH (VARNISH)
Use the HTF-2 Floor Sander to sand between coats of
floor finish, particularly when using water based
varnishes. These types of finishes tend to raise the
wood grain when first applied to raw wood. Allow
each coat of varnish to dry completely following the
manufactures directions. Use Hiretech abrasive pads
to sand between each coat of varnish. The fine
abrasive pads will remove light brush/applicator
marks and raised grain while maintaining the
integrity of the coat of varnish applied

SERVICE & ROUTINE MAINTENANCE
CAUTION - maintenance and repairs
must be carried out by authorised
personnel only. To prevent injury, always
remove the power cable from the power
supply before undertaking any work on
the machine. Do not operate the floor
sander unless it is fully assembled and all
guards are in place. Use Hiretech
genuine spare parts only.
General
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 HT8-1.2 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
8).
4. The HT8-1.2 needs no lubrication during routine
servicing.
5. Always ensure that the electrical supply is
disconnected before starting any routine
servicing or repair.
Visual Inspection
1. Check that the drum guard Ref.35 is in good
condition and functioning correctly. Ensure that
the Warning Label Ref.36 is present and legible.
2. Check all other guards and mechanical parts are
in good condition.
3. Examine the power cable Ref.39 and the handle
cable Ref.20. 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
4. Examine both the mains plug and the
interconnecting socket, Body Twist Lock Ref.24.
The plugs must be opened and examined (see
Electrical Testing page 8).
5. If a cloth type bag is in service check the
condition, old clogged cloth dust bags make for
an inefficient dust pickup.
6. Ensure that all labels are present and in good
condition.
Drive Belts
1. To examine the condition of the Drive Belts
Ref.164 and Ref.165 remove the four screws
Ref.83 and the Belt Guard Ref.81.
2. Lift the Fan Belt Ref.165 while rotating the pulley
remove the fan belt. Repeat for the Drum Belt
Ref.164.
CAUTION - take care to avoid trapping
your fingers when removing or replacing
the drive belts.
3. Examine the pulleys for wear, worn or damaged
pulleys should be replaced
4. To reduce the instance of belt breakage, examine
the drive belts, look for cracks or fraying and
replace if necessary with new belts. To replace
reverse the above procedure taking care to avoid
bending the belts tighter than the pulley diameter
as this can result in damaged belts. Refit the belt
guard.
Dust Control System
1. For efficient dust pick up ensure that cloth type
dust bags are clean and unclogged and that the
intake is clear and properly adjusted.
2. Turn the machine on to its side and loosen the
three Screws Ref.71 and remove the Dust Shoe
Ref.72 and clear any obstruction. The grit from
the abrasive paper can wear away the leading
edge of the dust shoe, if this has occurred then
file or grind the leading edge level before
refitting.
Install the dust shoe ensuring that the clearance
between the shoe and the drum is maintained at
3/8“ (10mm).
Lubrication
1. The HT8-1.2 is completely lubricated. The
bearings are sealed and do not require
lubrication. In the unlikely event that a bearing
requires replacement use a Hiretech genuine
spare part only as the grease contained in these
bearings is special. A standard bearing is not
suitable and may result in further damage.
Sanding Drum.
Note: In operation The sanding belt is held in place
on the sanding drum by centrifugal force. It is
important that the drum rubber and abrasive guides
are maintained in good condition at all times.
Store and transport the HT8 EX with a sanding belt in
place at all times to protect the drum rubber.
1. Check that power supply is disconnected. Tilt the
machine back and rest the handle on the floor.

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
Hiretech Service Agent. Hiretech operate a
simple exchange program to replace HT8 EX
Sanding Drums. Please contact your local
service agent for information, service levels and
pricing. For further information visit.

Check the condition of the Abrasive Guides3.
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 3mm (0.12in).
4. When fitting new Abrasives Guides ensure that
the correct gap is maintained between the edge
of th sanding drum and the Abrasive Guide fitted
to the inside face of sanding drum (frame side).
Remove any abrasive belt fitted, using the Spacer
Guide Abrasive Ref.143 adjust the gap between
the Abrasive Guide and the edger of the sanding
drum as follows;
200mm wide abrasive - gap 1.5 to 2.5mm
8in wide abrasive - gap 3/32 to 5/32in
Note: The Abrasive Guide fitted to the Drum
Guard Ref.35 is fixed and does not require
adjustment.
5. heckC 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.
Care of Motor
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 12mm ( / ”) or less in length.
15
32
Brushes MUST slide freely in the brush holders.
Brush ware is also indicated by the ‘triangular’
ware indicator stamped on genuine Hiretech
motor brushes marked with the HT symbol. See
illustration opposite.
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.

vii. Remove the four brushes. Remove the two
‘jacking’ screws.
viii. Thoroughly clean the brush assembly and
housing using a soft brush and a suitable
vacuum cleaner.
ix. Inspect the four brushes for damage or
wear and if any one brush is found to be
damaged or worn to a length of 5/8“
(16mm) or less in length then replace all
four brushes.
x. When replacing brushes ensure free
movement in each brush holder and fit the
brush with the shunt (pigtail) towards the
field coil. Ensure that each brush shunt is
connected securely with the screw, and
lock washer, two spare screws and lock
washers are provided with each pack of
brushes. Do not fit the brush springs at this
stage.
xi. Pull each brush up to the top of the holder
using the shunt wire to retain it in this
position for the next stage.
xii. Enter the assembly into the main frame
taking care to avoid contact between the
brushes and the commutator of the
armature, that the shield wall end is
correctly aligned with the main frame and
that no leads are trapped. There is a
depressed pattern on the shield wall end
and on the main frame to assist alignment.
Both the bearing fit and the main frame fit
are ‘light contact’ and may require lightly
tapping into position using a soft mallet.
DO NOT FORCE.
xiii. Replace and tighten the four countersunk
Screws Ref.31.
xiv. Remove the four brush block retaining
Screws Ref.31 and the single timing Screw
Ref.34 from the Shield-Wall End Ref.30.
The brush block assembly is now free to
rotate. To fit the brush springs rotate the
brush block assembly counter clockwise
(over towards the rear of the machine) until
the lower brush holder is accessible, fit the
brush spring by inserting into the holder
with the coil spring over the brush then
push down 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 spring and
brush for correct alignment and free
movement.
xv. Rotate the brush block assembly clockwise

Electrical Testing
CAUTION - testing for electrical safety
should be undertaken by a competent
person and all results recorded. Do not
exceed 1250 volt insulation test duration
of 3 seconds.
1. Examine the power cable and handle cable for
damage, if the outer insulation shows more than
the slightest of abrasions or the inner conductors
are exposed then the cable must be replaced.
The cables must not be repaired with tape or
insulation sleeve.
2. Open and check mains plug and interconnecting
socket Ref.24 for condition, loose connections,
damaged wires etc. Ensure that the strain relief
of the power cable plug is correctly secured to the
outer cable insulation.
3. Open and examine the Switch Housing Ref.11
for loose connections, damaged wires, and
general condition. 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.
4. Ensure that the Strain Relief Ref.5 is correctly
secured to the outer cable insulation.
Note: HT8-1.2 Floor Sanders manufactured from
October 1993 starting with Serial Number 00532
(110/120V) and 00779 (220/240V) feature a fully
protected circuit breaker which incorporates 'Low Volt
Protection'. This means that should the mains supply
be interrupted during use the switch will immediately
return to the 'OFF' position to protect the operator.
This feature, by preventing a circuit through the switch
unless mains voltage is present, also prevents a full
10
insulation (flash) test unless the test instrument has
' ' facility.test on run
If your instrument has this facility then:- replace the
switch cover 'A' taking care to avoid trapping leads
and ensuring that all dust gaskets are correctly
positioned. Check that the circuit breaker 'ON'
button does not lock in the 'ON' position when
depressed. The button must only lock 'ON' when
current is present. Before carrying out test ensure that
the motor is connected by the twist lock socket Ref. 24
and that all safety measures have been taken.
(Class 1 Earthed Appliance [U.K.] ) Carry out 'test on
run' procedure.
If your instrument does not have 'test on run' facility
then Continue as follows:-
5. While you have the switch housing open for
visual inspection remove the circuit breaker
cover 'B' together with the 'low volt coil 'C'(see
below). Do not disconnect or disturb any cables.
The 'low volt coils will remain within the cover 'B'.
The circuit breaker will now lock into the 'ON'
position without current present. Before carrying
out an insulation (flash) test ensure that the motor
is connected by the twist lock socket Ref. 24 and
that all safety measures have been taken.
6. Using standard procedure test for electrical
safety (Class 1 Earthed Appliance [U.K.] ). Do
not exceed 1250 volt flash duration of 3 seconds.
7. Record the test results.
8. Complete a functional (run) test and record
results.
CAUTION - when undertaking a
functional test ensure that the machine is
secure, remember the sanding drum will
rotate, ensure that the drum cannot come
into contact with the work bench/service
area.
9. After carrying out the tests disconnect the
machine from the test station and snap the 'Low
Volt Coil' 'C' back into position and replace cover
'B'.
10. Replace the switch cover 'A' taking care to avoid
trapping leads and ensuring that all dust gaskets
are correctly positioned. Check that the circuit
breaker 'ON' button does not lock in the 'ON'
position when depressed. The button must only
lock 'ON' when current is present.
11. Finally test the machine once again to ensure
good earth and insulation of the mains cable
and switch. Do not exceed 1250 volt flash
duration of 3 seconds.
