CORDLESS METAL CUTTER SAFETY WARNINGS GEB058-1

1. Keep hands away from cutting area and the blade.

Keep your second hand on auxiliary handle, or

motor housing. If both hands are holding the tool,

they cannot be cut by blade.

2. Do not reach underneath the workpiece. The guard

cannot protect you from the blade below the

3. Adjust the cutting depth to the thickness of the

workpiece. Less than a full tooth of the blade teeth

should be visible below the workpiece.

4. Never hold piece being cut in your hands or

across your leg. Secure the workpiece to a stable

platform. It is important to support the work properly

to minimize body exposure, blade binding, or loss of

5. Hold power tool by insulated gripping surfaces

when performing an operation where the cutting

tool may contact hidden wiring. Contact with a “live”

wire will also make exposed metal parts of the power

tool “live” and shock the operator.

6. When ripping always use a rip fence or straight

edge guide. This improves the accuracy of cut and

reduces the chance for blade binding.

7. Always use blades with correct size and shape

(diamond versus round) of arbour holes. Blades

that do not match the mounting hardware of the tool

will run eccentrically, causing loss of control.

8. Never use damaged or incorrect blade washers or

bolts. The blade washers and bolt were specially

designed for your tool, for optimum performance and

safety of operation.

9. Causes and operator prevention of kickback;

- Kickback is a sudden reaction to a pinched, bound

or misaligned blade, causing an uncontrolled tool to

lift up and out of the workpiece toward the operator.

- When the blade is pinched or bound tightly by the

kerf closing down, the blade stalls and the motor

reaction drives the unit rapidly back toward the

- If the blade becomes twisted or misaligned in the

cut, the teeth at the back edge of the blade can dig

into the top surface of the workpiece causing the

blade to climb out of the kerf and jump back toward

Kickback is the result of tool misuse and/or incorrect

operating procedures or conditions and can be

avoided by taking proper precautions as given below.

22. Rip fence (Guide rule)

Rated voltage D.C. 18V5

• Maintain a firm grip with both hands on the tool

and position your arms to resist kickback

forces. Position your body to either side of the

blade, but not in line with the blade. Kickback

could cause the tool to jump backwards, but

kickback forces can be controlled by the operator, if

proper precautions are taken.

• When blade is binding, or when interrupting a

cut for any reason, release the trigger and hold

the tool motionless in the material until the

blade comes to a complete stop. Never attempt

to remove the tool from the work or pull the tool

backward while the blade is in motion or

KICKBACK may occur. Investigate and take

corrective actions to eliminate the cause of blade

• When restarting a tool in the workpiece, center

the blade in the kerf and check that blade teeth

are not engaged into the material. If blade is

binding, it may walk up or kickback from the

workpiece as the tool is restarted.

• Support large panels to minimise the risk of

blade pinching and kickback. Large panels tend

to sag under their own weight.

Supports must be placed under the panel on both

sides, near the line of cut and near the edge of the

• Do not use dull or damaged blades.

Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade

binding and kickback.

• Blade depth and bevel adjusting locking levers

must be tight and secure before making cut. If

blade adjustment shifts while cutting, it may cause

binding and kickback.

• Use extra caution when making a “plunge cut”

into existing walls or other blind areas. The

protruding blade may cut objects that can cause

kickback. For plunge cuts, retract lower guard using

10. Check lower guard for proper closing before each

use. Do not operate the tool if lower guard does

not move freely and close instantly. Never clamp

or tie the lower guard into the open position. If tool

is accidentally dropped, lower guard may be bent.

Raise the lower guard with the retracting lever and

make sure it moves freely and does not touch the

blade or any other part, in all angles and depths of cut.

To check lower guard, open lower guard by hand, then

release and watch guard closure. Also check to see

that retracting handle does not touch tool housing.

Leaving blade exposed is VERY DANGEROUS and

can lead to serious personal injury.

11. Check the operation and condition of the lower

guard spring. If the guard and the spring are not

operating properly, they must be serviced before

use. Lower guard may operate sluggishly due to

damaged parts, gummy deposits, or a buildup of

12. Lower guard should be retracted manually only for

special cuts such as “plunge cuts” and

“compound cuts.” Raise lower guard by retracting

handle and as soon as blade enters the material,

the lower guard must be released. For all other

sawing, the lower guard should operate automatically.

13. Always observe that the lower guard is covering

the blade before placing tool down on bench or

floor. An unprotected, coasting blade will cause the

tool to walk backwards, cutting whatever is in its path.

Be aware of the time it takes for the blade to stop after

14. Do not stop the blades by lateral pressure on the

Do not attempt to remove cut material when blade

CAUTION: Blades coast after turn off.

16. Place the wider portion of the tool base on that

part of the workpiece which is solidly supported,

not on the section that will fall off when the cut is

17. Never attempt to make a cut with the tool held

upside down in a vise. This is extremely

dangerous and can lead to serious accidents.

Wear safety goggles and hearing protection

19. Always use blades recommended in this manual.

Do not use any abrasive wheels.

the battery cartridge.

• To remove the battery cartridge, withdraw it from the

tool while sliding the button on the side of the cartridge.

• To insert the battery cartridge, align the tongue on the

battery cartridge with the groove in the housing and slip

it into place. Always insert it all the way until it locks in

place with a little click. If you can see the red part on

the upper side of the button, it is not locked completely.

Insert it fully until the red part cannot be seen. If not, it

may accidentally fall out of the tool, causing injury to

you or someone around you.

• Do not use force when inserting the battery cartridge. If

the cartridge does not slide in easily, it is not being

Adjusting depth of cut (Fig. 2)

• After adjusting the depth of cut, always tighten the lever

Loosen the lever on the side of the rear handle and move

the base up or down. At the desired depth of cut, secure

the base by tightening the lever.

For cleaner, safer cuts, set cut depth so that no more than

one blade tooth projects below workpiece. Using proper

cut depth helps to reduce potential for dangerous

KICKBACKS which can cause personal injury.

When cutting, align the A position on the front of the base

with your cutting line on the workpiece.

Switch action (Fig. 4)

• Before inserting the battery cartridge into the tool,

always check to see that the switch trigger actuates

properly and returns to the “OFF” position when

• Do not pull the switch trigger hard without pressing the

lock-off lever. This can cause switch breakage.

To prevent the switch trigger from being accidentally

pulled, a lock-off lever is provided. To start the tool, press

the lock-off lever and pull the switch trigger.

Release the switch trigger to stop.

• For your safety, this tool is equipped with lock-off lever

which prevents the tool from unintended starting.

NEVER use the tool if it runs when you simply pull the

switch trigger without pressing the lock-off lever. Return

tool a MAKITA service center for proper repairs

BEFORE further usage.

• NEVER tape down or defeat purpose and function of

Lighting the lamp (Fig. 5)

with the lock-off lever being pressed.

• Use a cotton stick to wipe the dirt off the lens of lamp.

Be careful not to scratch the lens of lamp, or it may

lower the illumination.

• Do not use gasoline, thinner or the like to clean the lens

of lamp. Using such substances will damage the lens.

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

battery cartridge is removed before carrying out any

Removing or installing blade (Fig. 6)

• Be sure the blade is installed with teeth pointing up at

the front of the tool.

• Use only the Makita wrench to install or remove the

blade cannot revolve and use the wrench to loosen the

hex bolt counterclockwise. Then remove the hex bolt,

outer flange and blade.

To install the blade, follow the removal procedure in

reverse. BE SURE TO TIGHTEN THE HEX BOLT CLOCKWISE SECURELY. (Fig. 7)

When changing blade, make sure to also clean upper and

lower blade guards of accumulated chips and particles.

Such efforts do not, however, replace the need to check

lower guard operation before each use.7

Hex wrench storage (Fig. 8)

When not in use, store the hex wrench as shown in the

figure to keep it from being lost.

• Always insert the battery cartridge all the way until it

locks in place. If you can see the red part on the upper

side of the button, it is not locked completely. Insert it

fully until the red part cannot be seen. If not, it may

accidentally fall out of the tool, causing injury to you or

• Be sure to move the tool forward in a straight line

gently. Forcing or twisting the tool will result in

overheating the motor and dangerous kickback,

possibly causing severe injury.

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for

15 minutes before proceeding with a fresh battery.

• Never twist or force the tool in the cut. This may cause

motor overload and/or a dangerous kickback, resulting

in serious injury to the operator.

• Always wear eye protection or goggle before operation.

Hold the tool firmly. The tool is provided with both a front

grip and rear handle. Use both to best grasp the tool. If

both hands are holding the tool, they cannot be cut by the

blade. Set the base on the workpiece to be cut without the

blade making any contact. Then turn the tool on and wait

until the blade attains full speed. Now simply move the

tool forward over the workpiece surface, keeping it flat

and advancing smoothly until the cutting is completed.

To get clean cuts, keep your cutting line straight and your

speed of advance uniform. If the cut fails to properly follow

your intended cut line, do not attempt to turn or force the

tool back to the cut line. Doing so may bind the blade and

lead to dangerous kickback and possible serious injury.

Release switch, wait for blade to stop and then withdraw

tool. Realign tool on new cut line, and start cut again.

Attempt to avoid positioning which exposes operator to

chips and particles being ejected from the tool. Use eye

protection to help avoid injury.

The sight grooves in the base makes it easy to check the

distance between the front edge of the blade and the

workpiece whenever the blade is set to the maximum

depth of cut. (Fig. 10)

• Do not stack materials when cutting them.

• Do not cut hardened steel, stainless steel, wood,

plastics, concrete, tile, etc. Cut only mild steel and

• Do not touch the blade, workpiece or cutting chips with

your bare hand immediately after cutting, they may be

extremely hot and could burn your skin.

• Always use the blades appropriate for your job.

The use of inappropriate blades may cause a poor

cutting performance and/or present a risk of personal

Rip fence (guide rule) (Accessory)

The handy rip fence allows you to do extra-accurate

straight cuts. Simply slide the rip fence up snugly against

the side of the workpiece and secure it in position with the

screw on the front of the base. It also makes repeated

cuts of uniform width possible.

MAINTENANCE CAUTION:

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

battery cartridge is removed before attempting to

perform inspection or maintenance.

• Check the blade carefully for cracks or damage before

and after each use. Replace a cracked or damaged

• Continuing to use a dull blade may cause a dangerous

kickback and/or motor overload.

Replace with a new blade as soon as it no longer cuts

• Blades for metal cutter cannot be re-sharpened.

Replacing carbon brushes (Fig. 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. (Fig. 13)
