Page 6 of 17
Use only accessories that are recommended by the manufacturer for use with your product.
Accessories that may be suitable for one product may create a risk of injury when used with
another tool. Never use an accessory that has a lower operating speed or operating pressure than
the tool itself.
Keep guards in place and in working order. Never operate the product without the guards in place.
Do not leave the tool running unattended.
Specific Operation Warnings
⚠WARNING
Do not use to cut sheet metal that is thicker than 14 gauge.
To reduce the risk of injury, always wear eye protection.
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Never leave the tool unattended when it is plugged into an electrical outlet.
Never lay the tool down until the motor has come to a complete stop.
Grounding
⚠WARNING
This machine must be grounded while in use to protect the operator from electrical shock. This
unit is equipped with an electrical cord that has an equipment grounding conductor and a
grounding plug. The plug MUST be plugged into a matching receptacle that is properly installed
and grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper
receptacle installed by a qualified electrician.
CHECK with a qualified electrician or service person if you do not completely understand the
grounding instructions, or if you are not sure the tool is properly grounded.
Grounded Tools: Tools with 3-Prong Plugs
Tools marked with Grounding Required have a 3-wire cord and 3-prong grounding plug. The plug
must be connected to a properly grounded outlet. If the tool should electrically malfunction or break
down, grounding provides a low resistance path to carry electricity away from the user, reducing the
risk of electric shock. (See Figure A.)
The grounding prong in the plug is connected through the green wire inside the cord to the grounding
system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding
system and must never be attached to an electrically live terminal.
Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance
with all codes and ordinances. The plug and outlet should look like those in the following illustration.

Page 7 of 17
Double Insulated Tools: Tools with Two-Prong Plugs
Tools marked Double Insulated do not require grounding. They have a special double insulation
system which satisfies OSHA requirements and complies with the applicable standards of
Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code.
(See Figure B.)
Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration.
Extension Cords
⚠WARNING
USE A PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and cause
overheating.
Be sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it. Protect your extension
cords from sharp objects, excessive heat and damp or wet areas.
Grounded tools require a 3-wire extension cord. Double Insulated tools can use either a 2- or 3-
wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in
loss of power and possible tool damage.
The smaller the wire’s gauge number, the greater the capacity of the cord. For example, a 14-
gauge cord can carry a higher current than a 16-gauge cord. Minimum extension cord wire size is
shown in the following table:

When using more than one extension cord to make up the total length, make sure each cord
contains at least the minimum wire size required.
If you are using one extension cord for more than one tool, add the nameplate amperes and use
the sum to determine the required minimum cord size.
If you are using an extension cord outdoors, make sure it is marked with the suffix W-A (Win
Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition. Always replace
a damaged extension cord or have it repaired by a qualified electrician before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

Lubricating the Metal Shear
1. Make sure that the power switch is in the OFF position and plug in the metal shear.
2. Turn on the metal shear and run for one minute.
3. Turn off the metal shear and unplug from the outlet.
4. Place 3-4 drops of light machine oil in the oil port.
5. Turn the metal shear on its side and place 1-2 drops of light machine oil above the upper blade.
Note: Make a few practice cuts on scrap material before cutting your workpiece.
Operating Instructions
⚠WARNING
Do not use to cut sheet metal that is thicker than 14 gauge.
To reduce the risk of injury, always wear eye protection.
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Never leave the tool unattended when it is plugged into an electrical outlet.
Never lay the tool down until the motor has come to a complete stop.
The edge of sheet metal is very sharp. Always wear protective gloves when handling sheet metal.
DO NOT touch, change, or adjust the angle grinder until it is cool. Blades heat up dramatically
while in use and can burn you.
Do not use with the trigger locked on.

Adjusting the Cutting Blades
1. Using a probe through the motor vents in the side of the cover, turn the fan until the cutting blades
are open to the maximum amount. You can measure the gap between the blades using an
automotive feeler gauge (not included).
2. To determine the best spacing, use the following formula:
Distance in mm (L) =0.2x thickness of steel plate in mm.
This is the same as the gap being equal to the material thickness divided by 5. For example, a thin
steel plate which is 1 mm thick should be cut with a metal shear blade setting of 0.2 mm. This
assumes a hardness of the material of 390N/mm. For softer material, reduce the gap. For harder
material, increase the gap.
3. Loosen the socket head screw (6) that holds the upper shear blade (12) in place. Adjust the upper
shear blade until the space between the upper and lower cutting edge is between 0.1 mm and 0.6
mm. Then tighten the socket head screw (6) to move the upper shear blade (12) in position.
Note: Hold the metal shear by the insulated gripping surfaces when performing an operation where
the cutting accessory may contact hidden wiring or its own cord.

After Each Use
⚠WARNING
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
Do not touch the metal shear right after use.
Replacing the Blades
1. Remove the screw and washer (6, 5, 4) holding the upper shear blade (reference area 12) and
remove it as shown in the image below, using the included hex key.
2. Remove the screw and washer (6, 5, 4) holding the lower shear blade (reference area 2) and
remove it as in image below.
3. To reinstall sharpened blades or new blades, first reinstall the lower shear blade (2) and tighten it.
Then install the upper shear blade (12) but leave it just loose enough to slide.
4. The upper shear blade (12) has an adjusting screw (8) and second screw (6) that are used to
adjust the blade’s position. The screw (6) should be loosened with a wrench. Then the lock nut (7)
should be loosened and held using a box-end wrench (not included) and the adjusting screw can be
adjusted. The upper shear blade (12) should be adjusted for different material types or thicknesses.
Adjusting the Upper Shear Blade (12)
For sheet steel the formula is: Gap = steel thickness divided by 5.
The gap will be slightly smaller for rubbery or soft materials. The gap should be slightly larger for hard
materials.
When the two blades line up with the proper gap, tighten and hold the adjusting screw (8) while you
tighten the lock nut (7). Then, tighten the screw (6).
5. Check that the blades will operate properly before use. The machine should always be tested on
scrap material before use on final work material.
6. If you sharpen the blades, maintain the original dimensions of a 12° angle on the upper shear blade
(12) with an 8° angle across its thickness. Maintain a 4° angle on the butt of the lower shear blade (2)
as shown in the illustration on the following page.
