5.5. Adjusting the
Brobolube
Unit
When assembled, the Brobolube unit is a precise instrument that supplies an accurate quantity of lubricant directly
to the saw blade before it contacts the workpiece. There are 2 control variables available for the operator:
Air Flow (Volume) Delivery
Regulated with the tap (needle valve), this can be adjusted from initial, completely closed to fully open states.
It is highly recommended that the upper end of the flow range be utilized to allow adequate airflow to deposit &
evenly distributed the lubricant onto the blade while maintaining a fine lubricant mix. If the needle valve is not
open sufficiently, the air to lubricant ratio may vary & may result in a substandard distribution of lubricant to
reach the blade teeth.
Lubricator Flow Rate
This controls the fluid flow rate & is adjustable via the slotted needle valve situated on top of the lubricator. The
consumption of Brobolube is factory set to
4 drops per minute
. This has been examined to produce a sufficient mix
of air & lubricant, & it is recommended to use this initial setting. On this setting, approximately
55 cubic centimeters
(lubricator capacity) should last for
20 hours of continuous cutting
. If for some reason the setting needs to be
altered, the needle valve should be turned clockwise to reduce or anti-clockwise to increase the fluid flow
respectively.
NOTE
i.
Although the lubricator is capable of delivering a much higher flow rate of lubricant, it is suggested that you
do not increase the flow rate excessively because:
No significant increase in blade life or lubricating efficiency will be achieved (confirmed by test results).
Excessive application of
Brobolube
will only result in a waste of fluid.
The excessive application will produce swarf that will be wet (oily) & harder to clean up than dry swarf
produced from the correct supply of
Brobolube
.
ii.
The amount of Lubricant (when set correctly) delivered by the lubricator is not easily visible to the naked
eye. If in doubt that lubricant is being delivered, first check to see if lubricator itself is delivering droplets at
its sight glass. If still unsure whether lubricant is being delivered, disconnect the supply tubing to the tap
(needle valve) & hold the tube against some blotting paper for a few seconds while the lubricator is
operating.
