BASIC RECIPROCATING SAW OPERATIONS

–

Check for clearance beyond the workpiece so

the blade will not impact another surface.

–

Mark the line of cut clearly. If cutting metal,

apply cutting oil on the line.

–

Depress the trigger switch to start the saw and

bring it to maximum desired cutting stroke rate

before applying the blade to the workpiece.

–

Do not force the tool. Place the shoe firmly on

the workpiece while cutting. Use only enough

steady pressure on the blade to keep the saw

cutting. Reduce pressure as the blade comes

to the end of the cut.

–

Cutting stroke rates should vary with the

workpiece. Hard materials such as metals

require lower stroke rates, for softer materials

use higher stroke rates.

–

Check wood, chip boards, building materials

etc. for foreign objects (nails, screws, etc.)

before sawing and remove them, if necessary.

–

Position the pivoting footplate onto the surface

of the work and saw through the work applying

uniform contact pressure of feed.

If the saw blade jams, switch off the tool

immediately. Widen the saw cut with a suitable tool

and pull out the saw blade.

9.4 FLUSH CUTTING – FIG. 6

With the use of flexible bimetal saw blades,

projecting items (i.e. water pipes, etc.) can be

sawn off flush to the wall. Pay attention that the

saw blade always extends beyond the diameter of

the pipe being sawn. Danger of kickback.

Position the saw blade sidewards against the wall

and apply some lateral pressure via the tool so the

edge of the pivoting sole plate faces against the

wall. Switch the tool on and make the cut, applying

constant lateral pressure.
