Record the test results.
8.
Complete a functional (run) test and record
results.
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.
1.
Check that power supply is disconnected. Tilt the
machine back and rest the handle on the floor.
Open the drum guard and examine the drum
cover.
A damaged or worn cover must be
replaced to maintain machine performance. A
damaged or worn cover can result in poor
sanding with subsequent damage to the floor
surface and can be dangerous in operation. A
cover that is worn to 1/4“ or less in thickness
must be replaced.
2.
To replace the drum cover see the detailed
instructions included in each genuine Pacific
Floor Care Drum Cover Kit Ref.167 Part #
R162312. The use of an impact screwdriver may
assist.
3.
It is recommended that at each service interval
the drum cover is checked and trimmed
(dressed) if necessary to provide a true uniform
diameter.
4.
First check that the condition of the rear castors.
These must be in good condition and free from
dust and dirt. Check that the casters rotate freely
and are not worn with any flat spots. Check that
the axle between the castors is not bent by using
a straight edge along its length.
Use the standard test for electrical safety for a
grounded (earthed) appliance. Do not exceed
1250 volt insulation test duration of 3 seconds
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.
Sanding Drum.

5.
Fit a sheet of fine grit abrasive paper (120 grit),
abrasive side up on to a level floor surface.
Remove any abrasive paper from the drum and
re-tighten the clamp bar screws. Make sure the
clamp bar screws are tight.
Position the floor sander over the abrasive paper
and connect the power cable to the power
supply. Tip the floor sander back to raise the
sanding drum off the floor and switch on.
Gently lower the floor sander so the sanding
drum 'just' touches the abrasive paper. Hold the
sander in position for a few seconds then tip back
and switch off.
Disconnect the power cable and tip the floor
sander back so that it rests on it's handle. Lift the
drum guard and check the condition of the drum
cover. If it is uniform an even surface will be
witnessed, if not, continue to dress the drum until
all high and low spots are removed. Take care
not to remove too much material as this will
reduce the life of the drum cover.
6.
When a uniform surface is achieved it is
advisable to slightly ‘feather’ both edges of the
drum cover. Switch off and disconnect the power
cable from the power supply. Tilt the machine
back and lift the drum guard to expose the drum
cover.
Using a medium to fine grit abrasive
paper carefully feather the edge of both sides of
the drum cover by holding the abrasive paper
against the edge and rotating the drum.
Be
careful not to trap your fingers. The softer edge
provided will help prevent ‘cut’ lines witnessed
on the floor surface when sanding particularly in
softer woods. Always feather the edges of a new
drum cover.
WARNING - the sanding drum and drum
cover must be correctly adjusted and
maintained to ensure the best sanding
performance. Failure to do so can result
in damage to the floor surface and can
be dangerous.
