Machine Brushes - should be checked to make sure there is no abnormal wear present this
should be checked at least once a week if used frequently. If the brush has worn more than 2/3 the
original length the brushes should be changed. Failure to do so may cause damage to the
machine.
Magnetic base – before every operation the magnetic base should be checked to make sure that
the base is flat and there is no damage present. An uneven magnet base will cause the magnet not
to hold as efficiently and may cause injury to the operator.
Adjustment of slide and bearing bracket Alignment.
An essential requirement of the machine is that the slide can move in a smooth and controlled
manner, free of lateral movement and vibration.
This situation can be maintained by periodic adjustment of the slide and is accomplished in the
following manner:
1. Place the machine in an upright position and, by means of the capstan, raise the slide to
its highest position. Clean the brass gib strips and apply a small amount of light machine
oil to the wear surfaces.
2. Now lower the slide back to its lowest position. Bring the slide into the centre of the
dovetail slide housing and loosen screws thus allowing free movement of the arbor
support bracket.
3. Commencing with the middle screws, gently feed in all the screws until slight resistance
is encountered.
4. Operate the slide up and down a few times to test the movement and make any further
necessary adjustments. Try to ensure that all the screws are exerting a uniform pressure
on the slide from top to bottom. A perfectly adjusted slide will operate freely up and
down without any sideways movement.
5. Now raise the slide to its highest position. Slightly undo the arbor bearing bracket and,
using fingers only, tighten the screws.
6. Place the machine on a steel plate, connect to supply and switch on magnet. Start up the
motor. If the arbor is incorrectly aligned, the arbor support bracket will be seen to
oscillate. Make any necessary further adjustments to the bracket to ensure correct
alignment of the spindle and finally tighten the screws using a spanner. Lastly tighten the
arbor bearing bracket.
Check machines grease.
The gearbox grease should be checked once a month to ensure all moving components are
covered to prevent wear. The grease should be changed at least once a year to ensure you gain the
best from the machine.
Check Armature of the machine.
This should be checked at least 1 per month to check that there are visual signs of damage to the
body or to the commutator. Some signs of wear will be seen on the commutator over a period of
time this is normal as this is the part that comes in contact with the brushes but any signs of
abnormal damage and the part should be replaced.
