Using the Machine
(a)
Using the Grinding Wheel
(b)
Using the Sanding Belt
1. Position the sander work rest as required (see fig. 4) and adjust as stated in Maintenance (page 9)
2. Switch the motor ON by pushing the rocker switch so that the “ I ” is depressed, and allow the
machine to reach full speed. To switch the motor OFF push the switch so that the “ 0 ” is depressed.
3. Hold the workpiece firmly on the work rest and apply slight pressure to the sanding belt, allowing
the machine to do the work. If the belt does not run centrally, refer to page 11.
(1) For thin work pieces or sanding curves
(2) For general sanding and thicker work

Note : Although the unit is supplied assembled there is a possibility that the guards may
have moved during transit. Check the guards and make any adjustments necessary
(see Maintenance ) before starting the motor.
1. Turn the wheel by hand to ensure it is free, then switch ON by pushing the rocker switch so that
the “ I “ is depressed. To switch OFF push the switch so that the “ 0 ” is depressed.
2. Allow the machine to reach full speed, then hold the tool firmly on the tool rest and apply
slight pressure on to the grinding wheel, allowing the grinder to do the work.
Note : Never attempt to grind a piece of metal that is thinner than the gap between the tool
rest and the wheel (1.6 mm)
WARNING ! Applying excessive force to the grinding wheel can be dangerous and could
cause damage to the machine.
WARNING ! Do not attempt to use the side of the grinding wheel

Maintenance
WARNING ! Ensure the grinder is disconnected from the mains before carrying out any
maintenance.
(a)
Setting the Spark Arrester / Shield
Due to the reduction in diameter of the grinding wheel caused by wear, it is necessary
to check and adjust the clearance gap of the spark arrester and tool rest to maintain
suitable clearance from the wheel. It is recommended that a gap of 1.6 mm is maintained.
Slacken the spark arrestor securing screw and
position the arrester so that the recess is adjacent
to the wheel with a clearance of approximately
1.6 mm, (as shown in fig (5)). Tighten the screw to
secure in position.
Note: The Plastic Eye Shield, attached to the spark
arrester should be tight enough so that it does not
move under operational vibration, but loose enough
so that it may easily be positioned by hand.
(b)
Setting the Tool Rest
Slacken the two tool rest securing bolts and position
the rest so that it is adjacent to the wheel with a
clearance of approximately 1.6 mm, (as shown in
fig (6)). Tighten the two bolts to secure in position.
Note: The clearance between the grinding wheel
and tool rest should be maintained. If the clearance
gap is greater than the thickness of the metal being
ground there is a danger that the force of grinding
will cause the work piece to be pulled into the gap
with great force and is potentially very dangerous.
An incorrect gap could also cause “chatter” which
could result in damage to the wheel.
(c)
Setting the Sander Tool Rest
Slacken the knob that secures the work rest
in place and position the rest so that it is adjacent
to the belt edge and at 90
0
to the belts surface
with approximately 1.6 mm clearance (as shown
in fig (7)).Tighten the knob to secure in position.
Note: It is recommended that a set square is used to
gain the 90
0
angle. This will ensure an accurate square
finish when the workpiece is placed on rest.
