OPERATION MANUAL
The upper blade guide should be as close to the workpiece
as possible. This helps ensure straight cuts by keeping the
blade from twisting or drifting off the cut line. (Fig.4.9)

4.4 SETTING THE DOWN FEED
The down feed is the speed at which the saw blade cuts
through the workpiece. The rate at which the bow saw
drops is controlled by a valve that can be adjusted to in-
crease or decrease the speed that it moves.
To set the feed rate raise the bow to the highest position
and hold it in place with the feed ON/OFF lever. (Fig. 4.11)
Adjust the feed rate dial to the desired feed rate.
Start the saw and coolant pump and begin cutting.
Examining the chips is the best indication of the correct
blade speed and feed rate .
A.
This is the correct chip shape. The chip should be a
silver colour. If the chips are blue then decrease the
feed until they are silver. The shape also indicates that
the blade TPI is correct.
B.
This shape is in-correct. The shape is compressed and
indicates that the chip is too big for the tooth gullet.
This is the most common cause of broken teeth.
Either decrease the feed or change to a larger TPI.
