Maintenance and inspection
For the safety of yourself and others, always keep the machine in good condition.
Missing and damaged parts have to be replaced or repaired immediately.
Never do maintenance the machine while the electricity is
connected!
It is very important to clean the machine after use because of the thick layer of concrete that will
be left on the machine. This layer will keep for a long time, which in turn will cause a corrosive
attack. The layer may also prevent the machine from working properly.
Cleaning the electric motor is especially important since a layer of concrete reduces the motors
air-cooling ability, which may cause overheating, overload and failure.
Motor - loss of output
The motor has a maximum output limit. In addition to the
output required for the sawing, the total output is used for:
- Running the motor and the ball bearing friction,
-Friction in the V-belts, and
-Friction in the shaft bearing.
If the V-belt and/or shaft bearings are not properly adjusted,
this may cause a significant loss of output left for the
sawing. Therefore, keep these parts in good condition and
change shaft bearings when it shows signs of wear.
Control the V-belts
- In the beginning, V-belts must be checked after one day of
use, and if necessary tightened properly.
- Check the V-belts periodically. Loose V-belts will cause
wear and tear, and skidding causes loss of output for the
sawing spindle.
-If one V-belt breaks, change all of them. Missing V-belts
or uneven V-belt sets causes loss of output.
- When changing V-belts, make sure that the spindle, pulley
and the motor is adjusted perfectly on the centre line. Non-
parallel V-belts cause wear and tear on the new V-belts.
