Makita JS1600 ASSEMBLY

Permissible shearing thickness

The groove on the yoke serves as a thickness gauge for shearing mild or

stainless steel plate. If the material fits within the groove, it is shearable.

The thickness of materials to be sheared depends upon the type (strength) of

the material. The maximum shearing thickness is indicated in the table below

in terms of various materials. Attempting to shear materials thicker than indi-

cated will result in tool breakdown and/or possible injury. Keep within the thick-

ness shown in the table.

ASSEMBLY CAUTION:

•Always be sure that the tool is switched off and unplugged before

carrying out any work on the tool.

Before using the tool, check the blades for wear. Dull, worn blades will result in

poor shearing action, and the service life of the tool will be shortened.

Both the upper and lower blades have four cutting edges on each side (the

front and back). When the cutting edge becomes dull, rotate both the upper

and the lower blades 90° to expose new cutting edges.

When all eight edges are dull on both the upper and lower blades, replace

both blades with new ones. Each time blades are rotated or replaced, proceed

as follows.

Remove the blade securing bolts with the hex wrench provided and then rotate

or replace the blades.
