PART 5 ADJUSTMENT
CUTTING & FEEDING SPEEDS
• As previously highlights, the
rate of feed
largely affects the
quality
of the final cut. As such,
the blade life is also dependent on the feed at which it is cutting the sample material - in
particular, the type of material & also the crosssectional dimensions. Thus, to extend the
life of the blade,
maintain a firm & steady pressure whilst allowing the blade teeth to cut at
an optimum rate
.
Do not force
the blade through the material! This could cause numerous
problems including breaking the blade teeth, jamming the blade with the cutting part or
fracturing the blade spindle.
• The cutting action also generates a large amount of heat within the cutting sample due to
frictional contact. Should this heat affect the material you are cutting in any way, the heat
should be dissipated using the
coolant system
.
REFILLING THE LUBRICATOR
• To refill the lubricator bowl, twist the bowl anti-clockwise & slide it down to detach it from
the lubricator unit (There is no need to disconnect the air supply to the unit). The unit can
now be refilled to the line positioned near the top of the bowl, which is
approximately 10
millimeters from the top edge
of the bowl. Do not fill the bowl above this line, as the lubri-
cator unit will not function properly.
• Replace the lubricator bowl in a reverse manner by sliding the bowl upwards, ensuring that
the feed tube is located inside the bowl, & twist it clockwise to lock it into position.
ADJUSTING THE BROBOLUBE UNIT
When assembled, the Brobolube unit is a precise instrument that supplies an accurate quan-
tity of lubricant directly to the saw blade before it contacts the workpiece. There are 2 control
variables available for the operator:
1. 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 an adequate airflow to deposit & evenly distributed the lubri-
cant 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.
2. 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 min-
ute. This has been examined to produce a sufficient mix of air & lubricant, & it is recom-
mended 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.
