Frequently Asked Questions - JS1602 MAKITA

What materials can I cut with the Makita JS1602 shear?

You can cut mild steel (up to 1.6 mm), hard steel (up to 1.2 mm), stainless steel (up to 0.8 mm) and aluminum (up to 2.5 mm). The capacities depend on the material strength, expressed in N/mm².

How do I change or rotate the blades on the JS1602?

Unplug the tool. Use the supplied hex wrench to remove the clamping bolts. The upper and lower blades each have four cutting edges: you can rotate them to expose fresh edges. Replace the blades when all edges are dull. Tighten the bolts securely after changing.

What is the minimum cutting radius of the JS1602?

The minimum cutting radius is 30 mm when cutting in 1.0 mm mild steel.

How do I adjust the blade clearance?

A positioning screw for the lower blade is factory set and must not be modified. When reassembling, ensure there is no play between the upper blade and the blade holder, and that the lower blade touches the beveled parts of the yoke.

Can I use the shear continuously?

Yes, the slide switch can be locked in the ON position for continuous operation. To lock, press the front of the switch; to unlock, press the rear then push to OFF.

What are the important safety instructions?

Wear gloves and thick-soled shoes. Hold the tool firmly, secure the workpiece, keep hands away from blades. Do not cut electrical wires. Allow blades to cool after cutting. Do not leave the tool running unattended.

What to do if the blades are dull?

The blades have eight cutting edges in total. Rotate them to expose fresh edges. When all are dull, replace the blades with new ones (Makita part numbers). Use the supplied hex wrench.

What is the maximum cutting width?

For cut length up to 1800 mm, the maximum width is 100 mm for mild steel (1.6 mm) and 80 mm for stainless steel (1.2 mm). For thinner materials, the width is unlimited.

Is the shear double insulated?

Yes, the JS1602 has double insulation (class II) and can be plugged in without grounding. Ensure the voltage matches the rating plate.

Where can I get my Makita shear repaired?

Repairs, inspection, and carbon brush replacement must be carried out at an authorized Makita service center, using only Makita replacement parts to ensure safety and reliability.

ENE037-1

Intended use

The tool is intended for cutting sheet steel and stainless sheet steel.

ENF002-2

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated and can, therefore, also be used from sockets without earth wire.

General Power Tool SafetyWarnings

WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

GEB027-3

SHEAR SAFETY WARNINGS

1. Hold the tool firmly.
2. Secure the workpiece firmly.
3. Keep hands away from moving parts.
4. Edges and chips of the workpiece are sharp. Wear gloves. It is also recommended that you put on thickly bottomed shoes to prevent injury.
5. Do not put the tool on the chips of the workpiece. Otherwise it can cause damage and trouble on the tool.
6. Do not leave the tool running. Operate the tool only when hand-held.
7. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.
8. Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
9. Avoid cutting electrical wires. It can cause serious accident by electric shock.
10. Do not operate the tool at no-load unnecessarily.

SAVE THESE INSTRUCTIONS.

WARNING:

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Switch action (Fig. 1)

CAUTION:

• Before plugging in the tool, always check to see that the slide switch actuates properly and returns to the "OFF" position when the rear of the slide switch is depressed.
• Switch can be locked in "ON" position for ease of operator comfort during extended use. Apply caution when locking tool in "ON" position and maintain firm grasp on tool.

To start the tool, slide the slide switch toward the "I (ON)" position. For continuous operation, press the front of the slide switch to lock it.

To stop the tool, press the rear of the slide switch, then slide it toward the "O (OFF)" position.

Permissible shearing thickness (Fig. 2)

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 indicated will result in tool breakdown and/or possible injury. Keep within the thickness shown in the table.

Material	Tensile Strength (N/mm2)	Max. cutting thickness (mm)
Mild steel (A) 40	0 1.6 (16 ga)
Hard steel (B) 60	0 1.2 (18 ga)
Stainless steel 80	0 0.8 (22 ga)
Aluminum plate 200	0 2.5 (13 ga)

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Blade inspection

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.

Rotating or replacing blades (Fig. 3, 4, 5, 6, 7 & 8) 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.

Some tools have one washer between the upper blade and the blade holder. When the tool has the washer, be sure to use the thin washer when reassembling.

NOTE:

• No thin washers are used for the lower blade.

Install the upper blade and tighten the upper blade securing bolt with the hex wrench. Press up on the upper blade while tightening it.

After securing the upper blade, be sure that there is no gap left between the upper blade and the beveled surface of the blade holder.

When installing the lower blade onto the yoke, the lower blade should be pressed against the yoke so as to be contacting the beveled portions A and B of the yoke and the tip C of the lower blade positioning screw while you tighten the lower blade securing bolt. There must be no clearance between A, B and C during installation.

NOTE:

• The lower blade positioning screw is factory-assembled. Do not tamper with it.

OPERATION

Holding material and shearing method (Fig. 9)

WARNING:

• Before operating the tool, be sure to firmly tighten the upper blade securing bolt and the lower blade securing bolt. Loosen bolts may cause blades coming off, resulting in a serious injury.
• When cutting, always place the shear on the workpiece so that the material cut away is positioned on the right side to the operator.

The materials for cutting should be fastened to the workbench by means of workholders.

Always hold the tool firmly with one hand on housing. Do not touch the metal part.

Keep the shear moving parallel with the material.
