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 (cored) power tool or battery-operated (cordless) power tool.

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 switch trigger actuates properly and returns to the "OFF" position when released.
• 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, simply pull the switch trigger. Release the switch trigger to stop.

For continuous operation, pull the switch trigger and then push in the lock button.

To stop the tool from the locked position, pull the switch trigger fully, then release it.

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.

Max. cutting capacities mm ga.
Steel up to 400 N/mm2	3.2 10
Steel up to 600 N/mm2	2.5 13
Steel up to 800 N/mm2	1.5 17
Aluminum up to 200 N/mm2	4.0 9

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.

The service life of the blades varies in terms of the materials to be cut and the fixed blade clearance.

Roughly speaking, a blade can cut about 500m of 3.2mm mild steel with one cutting edge (total 2,000 m with four cutting edges).

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

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.

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.

Then install the lower blade like the upper blade while adjusting the clearance between the upper blade and lower blades. When performing this adjustment, the upper blade should be in the lowered position.

First, semi- tighten the lower blade securing bolt, then insert the thickness gauge for the desired clearance.

The cutting thickness is indicated on the thickness gauge so the combinations shown in the table below should be used. Work the lower blade positioning bolt on the yoke until the clearance is such that the thickness gauge moves only with some difficulty. Then firmly tighten the lower blade securing bolt. Finally, tighten the hex nut to secure the lower blade positioning bolt.

Thickness gauge combinations

Material thick-ness	2.3 mm(14 ga.)	2.5 mm(13 ga.)	3.2 mm(10 ga.)
Thickness gauge combinations	1.0 + 1.5	.0 + 1.5	+ 2.0

OPERATION

CAUTION:

• When cutting, always place the shear on the workpiece so that the material cut away is positioned on the right side to the operator.
• Hold the tool firmly with one hand on the main handle when performing the tool.

Holding material (Fig. 8)

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

Shearing method (Fig. 9)

For smooth cuts, tip the tool slightly backward while advancing it.

Maximum cutting width (Fig. 10)

Stay within the specified maximum cutting width (A):

Case of length 1,800 mm.

Mild steel (thickness)	3.2 mm Under 2.3 mm
Max. cutting width (A)	90 mm No limit

Stainless (thickness) 2.5 mm Under 2.0 mm

Max. cutting width (A) 70 mm No limit

006432

Minimum cutting radius

Minimum cutting radius is 50~mm when cutting 2.3mm mild steel.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

The tool and its air vents have to be kept clean. Regularly clean the tool's air vents or whenever the vents start to become obstructed.

Replacing carbon brushes (Fig. 11 & 12)

Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes.

Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
