Operation

1.
Fitting Sanding Disk.
a) Select disk to be used. (MUST be correct disks with velcro fitting ability).
b) Ensure sander is switched OFF and plug is removed from socket.
c) Line up holes in disk with those on machine pad. (This is necessary for dust
extraction), press disk firmly onto pad to secure it.
2.
Handgrips.
Your sander is fitted with two handgrips to ensure full control of the machine.
a) Fixed handgrip (handle) with ON/OFF switch and power cable.
b) Adjustable support grip. This can be adjusted for position by loosening handgrip
slightly, (unscrew anticlockwise) and rotating handgrip around body of machine,
to desired position, then tighten securely, hand tight only.
3.
Dust Collection.
The dust collection bag is fitted by simply inserting assy into the waste duct bellow
the ON/OFF switch.
Note :
Dust bag must be emptied regularly, do not wait until it is completely full.
Dust bag is emptied as follows.
a) Ensure sander is switched OFF and isolated by removing plug from socket.
b) Gently remove dust bag assy from sander by turning whilst pulling.
c) Take dust bag assy to dustbin and slip bag off, (bag has elasticated top), empty
bag into bin.
d) Reassemble dust bag assy and fit back on to sander.
To operate, insert the plug into the mains socket and switch on, holding sander firmly with
both hands depress ON/Off switch located below handle, variable speed is achieved by
depressing the switch fully for maximum speed or less for slower speed.
To control the speed so that it remains constant, turn the knob located on the switch in the
direction marked, i.e. - = lower speed + = higher speed.
The ON/Off switch can be locked for continuous sanding once depressed, to release the
switch, just depress again and release, (motor will stop).
Once machine has reached required speed, offer disk to workpiece and work gently
backwards and forwards across work until finished, remove sander from workpiece and
release switch, (wait until motor has stopped fully before putting tool down).

Maintenance

Always inspect the tool before use, and ensure it is in top condition.
Ensure all air vents are clear, (use compressed air to clean the machine where possible).
Check the power cable to ensure it is sound and free from cracks, bare wires etc. avoid
using solvents when cleaning plastic parts, most plastics are susceptible to damage from
the various types of commercial solvents.
All bearings etc., in this tool are lubricated with a sufficient amount of high grade lubricant
for the tools lifetime under normal operating conditions, therefore no further lubrication is
required.
