dovetail slide housing and loosen screws thus allowing free movement of the arbor
support bracket.

resistance is encountered.

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.

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.
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.
