OPERATION (cont.)
Cutting
It is recommended to first mark your intended cutting line with a pencil or
appropriate marker.
Start the tool and wait a short moment until the blade achieves maximum
speed. Put the bottom of the base on the work piece and move forward
slowly along the cutting line. Take extra care and time when cutting curved
lines, this reduces stress on the blade and avoids blade breakage.
Let the tool work at its own pace. Do not overload.
Cutting Metal
Your jigsaw can be used for cutting light gauge ferrous sheet and non-ferrous
metals such as copper, brass, aluminium, etc. It is advisable when cutting
sheet metal to clamp a backing sheet of soft wood or plywood to the work
as this will enable you to obtain a clean cut without vibration and the
possibility of tearing the metal. Both metal and wood backing are sawn
together. Do not force the cutting blade into the metal as this will reduce the
life of the blade and possibly damage the motor. Cutting thin metal will take
longer than cutting even a relatively thick piece of wood, so do not be
tempted to speed up the operation by forcing the saw. Spread a thin film of
oil along the proposed cutting line before commencing to saw metal. Always
select the right blade for the job.
Pocket and Round Cutting
When needing to start a cut from the centre of a work piece, drill a hole
using a 12mm drill bit to allow the blade to pass through the hole in order to
begin the cut. When cutting tight curves reduce the speed of the saw.
